Spansion Inc. reserves the right to change or discontinue work on this proposed product without notice. Data Sheet (Advance Information) General Description The S29AL016J is a 16 Mbit, 3.0 Volt-only Flash memory organized as 2,097,152 bytes or 1,048,576 words. The device is offered in 48-ball Fine-pitch BGA (0.8 mm pitch), 64-ball Fortified BGA (1.0 mm pitch) and 48pin TSOP packages. The word-wide data (x16) appears on DQ15-DQ0; the byte-wide (x8) data appears on DQ7-DQ0. This device is designed to be programmed in-system with the standard system 3.0 volt VCC supply. A 12.0 V VPP or 5.0 VCC are not required for write or erase operations. The device can also be programmed in standard EPROM programmers. The device offers access time of 55 ns allowing high speed microprocessors to operate without wait states. To eliminate bus contention the device has separate chip enable (CE#), write enable (WE#) and output enable (OE#) controls. The device requires only a single 3.0 volt power supply for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations. The S29AL016J is entirely command set compatible with the JEDEC single-power-supply Flash standard. Commands are written to the command register using standard microprocessor write timings. Register www..com contents serve as input to an internal state-machine that controls the erase and programming circuitry. Write cycles also internally latch addresses and data needed for the programming and erase operations. Reading data out of the device is similar to reading from other Flash or EPROM devices. Device programming occurs by executing the program command sequence. This initiates the Embedded Program algorithm--an internal algorithm that automatically times the program pulse widths and verifies proper cell margin. The Unlock Bypass mode facilitates faster programming times by requiring only two write cycles to program data instead of four. Device erasure occurs by executing the erase command sequence. This initiates the Embedded Erase algorithm--an internal algorithm that automatically preprograms the array (if it is not already programmed) before executing the erase operation. During erase, the device automatically times the erase pulse widths and verifies proper cell margin. The host system can detect whether a program or erase operation is complete by observing the RY/BY# pin, or by reading the DQ7 (Data# Polling) and DQ6 (toggle) status bits. After a program or erase cycle has been completed, the device is ready to read array data or accept another command. The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the data contents of other sectors. The device is fully erased when shipped from the factory. Hardware data protection measures include a low VCC detector that automatically inhibits write operations during power transitions. The hardware sector protection feature disables both program and erase operations in any combination of the sectors of memory. This can be achieved in-system or via programming equipment. The Erase Suspend/Erase Resume feature enables the user to put erase on hold for any period of time to read data from, or program data to, any sector that is not selected for erasure. True background erase can thus be achieved. The hardware RESET# pin terminates any operation in progress and resets the internal state machine to reading array data. The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the device, enabling the system microprocessor to read the boot-up firmware from the Flash memory. The device offers two power-saving features. When addresses have been stable for a specified amount of time, the device enters the automatic sleep mode. The system can also place the device into the standby mode. Power consumption is greatly reduced in both these modes. Spansion combines years of flash memory manufacturing experience to produce the highest levels of quality, reliability and cost effectiveness. The device electrically erases all bits within a sector simultaneously via Fowler-Nordheim tunneling. The data is programmed using hot electron injection. 4 S29AL016J S29AL016J_00_04 March 25, 2008 Data Sheet (Advance Information) Table of Contents Distinctive Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 General Description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 1. 2. 3. 4. 5. 6. 7.

Device Bus Operations This section describes the requirements and use of the device bus operations, which are initiated through the internal command register. The command register itself does not occupy any addressable memory location. The register is composed of latches that store the commands, along with the address and data information needed to execute the command. The contents of the register serve as inputs to the internal state machine. The state machine outputs dictate the function of the device. Table 7.1 lists the device bus operations, the inputs and control levels they require, and the resulting output. The following subsections describe each of these operations in further detail. Table 7.1 S29AL016J Device Bus Operations DQ8-DQ15 Operation Read Write CE# L L VCC 0.3 V L X OE# L H X H X WE# H L X H X RESET# H H VCC 0.3 V H L WP# X (Note 3) H X X Addresses (Note 1) AIN AIN X X X Sector Address, A6 = L, A3 = A2 = L, A1 = H, A0 = L Sector Address, A6 = H, A3 = A2 = L, A1 = H, A0 = L AIN DQ0- DQ7 DOUT (Note 4) High-Z High-Z High-Z BYTE# = VIH DOUT (Note 4) High-Z High-Z High-Z BYTE# = VIL DQ8-DQ14 = High-Z, DQ15 = A-1 High-Z High-Z High-Z www..com Standby Output Disable Reset Sector Protect (Note 2) L H L VID X (Note 4) X X Sector Unprotect (Note 2) Temporary Sector Unprotect L H L VID H (Note 4) X X X X X VID H (Note 4) (Note 4) High-Z Legend L = Logic Low = VIL; H = Logic High = VIH; VID = 8.5 V to 12.5 V; X = Don't Care; AIN = Address In; DOUT = Data Out Notes 1. Address In = Amax:A0 in WORD mode (BYTE#=VIH), Address In = Amax:A-1 in BYTE mode (BYTE#=VIL). Sector addresses are Amax to A12 in both WORD mode and BYTE mode. 2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See the "Sector/Sector Block Protection and Unprotection" section. 3. If WP# = VIL, the outermost sector(s) remains protected (determined by device configuration). If WP# = VIH, the outermost sector protection depends on whether the sector(s) was last protected or unprotected using the method described in Section 7.10, Sector Protection/Unprotection on page 19. 4. DIN or DOUT as required by command sequence, data polling, or sector protection algorithm. 7.1 Word/Byte Configuration The BYTE# pin controls whether the device data I/O pins DQ15-DQ0 operate in the byte or word configuration. If the BYTE# pin is set at logic 1, the device is in word configuration, DQ15-DQ0 are active and controlled by CE# and OE#. If the BYTE# pin is set at logic 0, the device is in byte configuration, and only data I/O pins DQ0-DQ7 are active and controlled by CE# and OE#. The data I/O pins DQ8-DQ14 are tri-stated, and the DQ15 pin is used as an input for the LSB (A-1) address function. 7.2 Requirements for Reading Array Data To read array data from the outputs, the system must drive the CE# and OE# pins to VIL. CE# is the power control and selects the device. OE# is the output control and gates array data to the output pins. WE# should remain at VIH. The BYTE# pin determines whether the device outputs array data in words or bytes. The internal state machine is set for reading array data upon device power-up, or after a hardware reset. This ensures that no spurious alteration of the memory content occurs during the power transition. No command is necessary in this mode to obtain array data. Standard microprocessor read cycles that assert valid addresses 14 S29AL016J S29AL016J_00_04 March 25, 2008 Data Sheet (Advance Information) on the device address inputs produce valid data on the device data outputs. The device remains enabled for read access until the command register contents are altered. See Reading Array Data on page 27 for more information. Refer to the AC Read Operations on page 41 for timing specifications and to Figure 17.1 on page 41 for the timing diagram. ICC1 in DC Characteristics on page 39 represents the active current specification for reading array data. 7.3 Writing Commands/Command Sequences To write a command or command sequence (which includes programming data to the device and erasing sectors of memory), the system must drive WE# and CE# to VIL, and OE# to VIH. For program operations, the BYTE# pin determines whether the device accepts program data in bytes or words. See Word/Byte Configuration on page 14 for more information. The device features an Unlock Bypass mode to facilitate faster programming. Once the device enters the Unlock Bypass mode, only two write cycles are required to program a word or byte, instead of four. Word/ Byte Program Command Sequence on page 28 has details on programming data to the device using both www..com standard and Unlock Bypass command sequences. An erase operation can erase one sector, multiple sectors, or the entire device. Table 7.2 on page 17 and Table 7.1 on page 18 indicate the address space that each sector occupies. A "sector address" consists of the address bits required to uniquely select a sector. The Command Definitions on page 27 has details on erasing a sector or the entire chip, or suspending/resuming the erase operation. After the system writes the autoselect command sequence, the device enters the autoselect mode. The system can then read autoselect codes from the internal register (which is separate from the memory array) on DQ7-DQ0. Standard read cycle timings apply in this mode. Refer to Autoselect Mode on page 19 and Autoselect Command Sequence on page 27 for more information. ICC2 in DC Characteristics on page 39 represents the active current specification for the write mode. AC Characteristics on page 41 contains timing specification tables and timing diagrams for write operations. 7.4 Program and Erase Operation Status During an erase or program operation, the system may check the status of the operation by reading the status bits on DQ7-DQ0. Standard read cycle timings and ICC read specifications apply. Refer to Write Operation Status on page 33 for more information, and to AC Characteristics on page 41 for timing diagrams. 7.5 Standby Mode When the system is not reading or writing to the device, it can place the device in the standby mode. In this mode, current consumption is greatly reduced, and the outputs are placed in the high impedance state, independent of the OE# input. The device enters the CMOS standby mode when the CE# and RESET# pins are both held at VCC 0.3 V. (Note that this is a more restricted voltage range than VIH.) If CE# and RESET# are held at VIH, but not within VCC 0.3 V, the device will be in the standby mode, but the standby current will be greater. The device requires standard access time (tCE) for read access when the device is in either of these standby modes, before it is ready to read data. If the device is deselected during erasure or programming, the device draws active current until the operation is completed. ICC3 and ICC4 represents the standby current specification shown in the table in DC Characteristics on page 39. March 25, 2008 S29AL016J_00_04 S29AL016J 15 Data Sheet (Advance Information) 7.6 Automatic Sleep Mode The automatic sleep mode minimizes Flash device energy consumption. The device automatically enables this mode when addresses remain stable for tACC + 30 ns. The automatic sleep mode is independent of the CE#, WE#, and OE# control signals. Standard address access timings provide new data when addresses are changed. While in sleep mode, output data is latched and always available to the system. ICC4 in the DC Characteristics on page 39 represents the automatic sleep mode current specification. 7.7 RESET#: Hardware Reset Pin The RESET# pin provides a hardware method of resetting the device to reading array data. When the system drives the RESET# pin to VIL for at least a period of tRP, the device immediately terminates any operation in progress, tristates all data output pins, and ignores all read/write attempts for the duration of the RESET# pulse. The device also resets the internal state machine to reading array data. The operation that was interrupted should be reinitiated once the device is ready to accept another command sequence, to ensure data integrity. www..com Current is reduced for the duration of the RESET# pulse. When RESET# is held at VSS 0.3V, the device draws CMOS standby current (ICC4). If RESET# is held at VIL but not within VSS 0.3/0.1V, the standby current will be greater. The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the Flash memory, enabling the system to read the boot-up firmware from the Flash memory. If RESET# is asserted during a program or erase operation, the RY/BY# pin remains a 0 (busy) until the internal reset operation is complete, which requires a time of tREADY (during Embedded Algorithms). The system can thus monitor RY/BY# to determine whether the reset operation is complete. If RESET# is asserted when a program or erase operation is not executing (RY/BY# pin is 1), the reset operation is completed within a time of tREADY (not during Embedded Algorithms). The system can read data tRH after the RESET# pin returns to VIH. Refer to the tables in AC Characteristics on page 41 for RESET# parameters and to Figure 17.2 on page 42 for the timing diagram. 7.8 Output Disable Mode When the OE# input is at VIH, output from the device is disabled.

This mode is primarily intended for programming equipment to automatically match a device to be programmed with its corresponding programming algorithm. However, the autoselect codes can also be accessed in-system through the command register. When using programming equipment, the autoselect mode requires VID (8.5 V to 12.5 V) on address pin A9. Address pins A6 and A3-A0 must be as shown in Table 7.5. In addition, when verifying sector protection, the sector address must appear on the appropriate highest order address bits (see Table 7.2 on page 17 and Table 7.1 on page 18). Table 7.5 shows the remaining address bits that are don't care. When all necessary bits have been set as required, the programming equipment may then read the corresponding identifier code on DQ7-DQ0. To access the autoselect codes in-system, the host system can issue the autoselect command via the command register, as shown in Table 10.1 on page 32. This method does not require VID. See Command Definitions on page 27 for details on using the autoselect mode. www..com Table 7.5 S29AL016J Autoselect Codes (High Voltage Method) A19 to A10 X X Byte Word Byte L L L L L L L L H H X H H SA VID X L X L L H X X X L X L H L X X L X L H H X 00h (unprotected) 8Eh (factory locked) 0Eh (not factory locked) 96h (factory locked) 16h (not factory locked) 49h 01h (protected) A8 to A7 X X A5 to A4 X X A3 to A2 L L DQ8 to DQ15 X 22h VID L L H X 22h C4h 49h DQ7 to DQ0 01h C4h Description Manufacturer ID: Spansion Device ID: S29AL016J (Top Boot Block) Device ID: S29AL016J (Bottom Boot Block) Sector Protection Verification Mode CE# L OE# L L WE# H H A9 VID A6 L A1 L A0 L Word L VID VID VID Secured Silicon Sector Indicator Bit (DQ7) Top Boot Block Secured Silicon Sector Indicator Bit (DQ7) Bottom Boot Block L L H X L L H X X L X L H H X Legend L = Logic Low = VIL; H = Logic High = VIH; SA = Sector Address; X = Don't care Note The autoselect codes may also be accessed in-system via command sequences. See Table 10.1 on page 32. 7.10 Sector Protection/Unprotection The hardware sector protection feature disables both program and erase operations in any sector. The hardware sector unprotection feature re-enables both program and erase operations in previously protected sectors. The device is shipped with all sectors unprotected. Spansion offers the option of programming and protecting sectors at its factory prior to shipping the device through Spansion's ExpressFlashTM Service. Contact a Spansion representative for details. It is possible to determine whether a sector is protected or unprotected. See Autoselect Mode on page 19 for details. Sector protection/unprotection can be implemented via two methods. The primary method requires VID on the RESET# pin only, and can be implemented either in-system or via programming equipment. Figure 7.3 on page 21 shows the algorithms and Figure 17.12 on page 48 shows the timing diagram. This method uses standard microprocessor bus cycle timing. For sector unprotect, all unprotected sectors must first be protected prior to the first sector unprotect write cycle. The alternate method intended only for programming equipment requires VID on address pin A9 and OE#. This method is compatible with programmer routines written for earlier 3.0 volt-only Spansion flash devices. Details on this method are provided in a supplement, publication number 21468. Contact a Spansion representative to request a copy.

The Sector Unprotect mode is activated by setting the RESET# pin to VID. During this mode, formerly protected sectors can be programmed or erased by selecting the sector addresses. Once VID is removed from the RESET# pin, all the previously protected sectors are protected again. Figure 7.2 shows the algorithm, and Figure 17.11 on page 48 shows the timing diagrams, for this feature.

Secured Silicon Sector Flash Memory Region The Secured Silicon Sector feature provides a 256-byte Flash memory region that enables permanent part identification through an Electronic Serial Number (ESN). The Secured Silicon Sector uses a Secured Silicon Sector Indicator Bit (DQ7) to indicate whether or not the Secured Silicon Sector is locked when shipped from the factory. This bit is permanently set at the factory and cannot be changed, which prevents cloning of a factory-locked part. This ensures the security of the ESN once the product is shipped to the field. Spansion offers the device with the Secured Silicon Sector either factory-locked or customer-lockable. The factory-locked version is always protected when shipped from the factory, and has the Secured Silicon Sector Indicator Bit permanently set to a 1. The customer-lockable version is shipped with the Secured Silicon Sector unprotected, allowing customers to utilize the that sector in any manner they choose. The customerlockable version has the Secured Silicon Sector Indicator Bit permanently set to a 0. Thus, the Secured Silicon Sector Indicator Bit prevents customer-lockable devices from being used to replace devices that are factory locked. The system accesses the Secured Silicon Sector through a command sequence (see Enter/Exit Secured Silicon Sector Command Sequence on page 28). After the system writes the Enter Secured Silicon Sector www..com command sequence, it may read the Secured Silicon Sector by using the addresses normally occupied by the boot sectors. This mode of operation continues until the system issues the Exit Secured Silicon Sector command sequence, or until power is removed from the device. On power-up, or following a hardware reset, the device reverts to sending commands to the boot sectors. 8.1 Factory Locked: Secured Silicon Sector Programmed and Protected at the Factory In a factory locked device, the Secured Silicon Sector is protected when the device is shipped from the factory. The Secured Silicon Sector cannot be modified in any way. The device is available pre-programmed with one of the following: A random, secure ESN only. Customer code through the ExpressFlash service. Both a random, secure ESN and customer code through the ExpressFlash service. In devices that have an ESN, a Bottom Boot device has the 16-byte (8-word) ESN in sector 0 at addresses 00000h-0000Fh in byte mode (or 00000h-00007h in word mode). In the Top Boot device, the ESN is in sector 34 at addresses 1FFFF0h-1FFFFFh in byte mode (or FFFF8h-FFFFFh in word mode). Customers may opt to have their code programmed by Spansion through the Spansion ExpressFlash service. Spansion programs the customer's code, with or without the random ESN. The devices are then shipped from the Spansion factory with the Secured Silicon Sector permanently locked. Contact a Spansion representative for details on using the Spansion ExpressFlash service. 8.2 Customer Lockable: Secured Silicon Sector NOT Programmed or Protected at the Factory The customer lockable version allows the Secured Silicon Sector to be programmed once, and then permanently locked after it ships from Spansion. Note that the unlock bypass functions is not available when programming the Secured Silicon Sector. The Secured Silicon Sector area can be protected using the following procedures: Write the three-cycle Enter Secured Silicon Region command sequence, and then follow the in-system sector protect algorithm as shown in Figure 7.3 on page 21, except that RESET# may be at either VIH or VID. This allows in-system protection of the Secured Silicon Sector without raising any device pin to a high voltage. Note that this method is only applicable to the Secured Silicon Sector. To verify the protect/unprotect status of the Secured Silicon Sector, follow the algorithm shown in Figure 8.1 on page 23. Once the Secured Silicon Sector is locked and verified, the system must write the Exit Secured Silicon Sector Region command sequence to return to reading and writing the remainder of the array. 22 S29AL016J S29AL016J_00_04 March 25, 2008 Data Sheet (Advance Information) The Secured Silicon Sector protection must be used with caution since, once protected, there is no procedure available for unprotecting the Secured Silicon Sector area, and none of the bits in the Secured Silicon Sector memory space can be modified in any way.

Common Flash Memory Interface (CFI) The Common Flash Interface (CFI) specification outlines device and host system software interrogation handshake, which allows specific vendor-specified software algorithms to be used for entire families of devices. Software support can then be device-independent, JEDEC ID-independent, and forward- and backward-compatible for the specified flash device families. Flash vendors can standardize their existing interfaces for long-term compatibility. This device enters the CFI Query mode when the system writes the CFI Query command, 98h, to address 55h in word mode (or address AAh in byte mode), any time the device is ready to read array data. The system can read CFI information at the addresses given in Table 9.1 to Table 9.4 on page 25. In word mode, the upper address bits (A7-MSB) must be all zeros. To terminate reading CFI data, the system must write the reset command. The system can also write the CFI query command when the device is in the autoselect mode. The device enters the CFI query mode, and the system can read CFI data at the addresses given in Table 9.1 to Table 9.4 on page 25.

In addition, the following hardware data protection measures prevent accidental erasure or programming, which might otherwise be caused by spurious system level signals during VCC power-up and power-down transitions, or from system noise. 9.1.1 Low VCC Write Inhibit When VCC is less than VLKO, the device does not accept any write cycles. This protects data during VCC power-up and power-down. The command register and all internal program/erase circuits are disabled, and the device resets. Subsequent writes are ignored until VCC is greater than VLKO. The system must provide the proper signals to the control pins to prevent unintentional writes when VCC is greater than VLKO. 9.1.2 Write Pulse Glitch Protection Noise pulses of less than 5 ns (typical) on OE#, CE# or WE# do not initiate a write cycle. 9.1.3 Logical Inhibit Write cycles are inhibited by holding any one of OE# = VIL, CE# = VIH or WE# = VIH. To initiate a write cycle, CE# and WE# must be a logical zero while OE# is a logical one. 9.1.4 Power-Up Write Inhibit If WE# = CE# = VIL and OE# = VIH during power up, the device does not accept commands on the rising edge of WE#. The internal state machine is automatically reset to reading array data on power-up. 26 S29AL016J S29AL016J_00_04 March 25, 2008 Data Sheet (Advance Information) 10. Command Definitions Writing specific address and data commands or sequences into the command register initiates device operations. Table 10.1 on page 32 defines the valid register command sequences. Writing incorrect address and data values or writing them in the improper sequence resets the device to reading array data. All addresses are latched on the falling edge of WE# or CE#, whichever happens later. All data is latched on the rising edge of WE# or CE#, whichever happens first. Refer to the appropriate timing diagrams in AC Characteristics on page 41. 10.1 Reading Array Data The device is automatically set to reading array data after device power-up. No commands are required to retrieve data. The device is also ready to read array data after completing an Embedded Program or Embedded Erase algorithm. After the device accepts an Erase Suspend command, the device enters the Erase Suspend mode. The system can read array data using the standard read timings, except that if it reads at an address within erasewww..com suspended sectors, the device outputs status data. After completing a programming operation in the Erase Suspend mode, the system may once again read array data with the same exception. See Erase Suspend/ Erase Resume Commands on page 30 for more information on this mode. The system must issue the reset command to re-enable the device for reading array data if DQ5 goes high, or while in the autoselect mode. See Reset Command on page 27. See also Requirements for Reading Array Data on page 14 for more information. The Read Operations on page 41 provides the read parameters, and Figure 17.1 on page 41 shows the timing diagram. 10.2 Reset Command Writing the reset command to the device resets the device to reading array data. Address bits are don't care for this command. The reset command may be written between the sequence cycles in an erase command sequence before erasing begins. This resets the device to reading array data. Once erasure begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in a program command sequence before programming begins. This resets the device to reading array data (also applies to programming in Erase Suspend mode). Once programming begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in an autoselect command sequence. Once in the autoselect mode, the reset command must be written to return to reading array data (also applies to autoselect during Erase Suspend). If DQ5 goes high during a program or erase operation, writing the reset command returns the device to reading array data (also applies during Erase Suspend). 10.3 Autoselect Command Sequence The autoselect command sequence allows the host system to access the manufacturer and devices codes, and determine whether or not a sector is protected. Table 10.1 on page 32 shows the address and data requirements. This method is an alternative to that shown in Table 7.5 on page 19, which is intended for PROM programmers and requires VID on address bit A9. The autoselect command sequence is initiated by writing two unlock cycles, followed by the autoselect command. The device then enters the autoselect mode, and the system may read at any address any number of times, without initiating another command sequence. A read cycle at address XX00h retrieves the manufacturer code. A read cycle at address XX01h returns the device code. A read cycle containing a sector address (SA) and the address 02h in word mode (or 04h in byte mode) returns 01h if that sector is protected, or 00h if it is unprotected. Refer to Table 7.2 on page 17 and Table 7.1 on page 18 for valid sector addresses. The system must write the reset command to exit the autoselect mode and return to reading array data. March 25, 2008 S29AL016J_00_04 S29AL016J 27 Data Sheet (Advance Information) 10.4 Enter/Exit Secured Silicon Sector Command Sequence The Secured Silicon Sector region provides a secured data area containing a random, sixteen-byte electronic serial number (ESN). The system can access the Secured Silicon Sector region by issuing the three-cycle Enter Secured Silicon Sector command sequence. The device continues to access the Secured Silicon Sector region until the system issues the four-cycle Exit Secured Silicon Sector command sequence. The Exit Secured Silicon Sector command sequence returns the device to normal operation. Table 10.1 on page 32 shows the addresses and data requirements for both command sequences. Note that the unlock bypass mode is not available when the device enters the Secured Silicon Sector. See also Secured Silicon Sector Flash Memory Region on page 22 for further information. 10.5 Word/Byte Program Command Sequence The system may program the device by word or byte, depending on the state of the BYTE# pin. Programming is a four-bus-cycle operation. The program command sequence is initiated by writing two unlock write cycles, followed by the program set-up command. The program address and data are written next, which in turn initiate the Embedded Program algorithm. The system is not required to provide further controls or timings. www..com The device automatically generates the program pulses and verifies the programmed cell margin. Table 10.1 on page 32 shows the address and data requirements for the byte program command sequence. When the Embedded Program algorithm is complete, the device then returns to reading array data and addresses are no longer latched. The system can determine the status of the program operation by using DQ7, DQ6, or RY/BY#. See Write Operation Status on page 33 for information on these status bits. Any commands written to the device during the Embedded Program Algorithm are ignored. Note that a hardware reset immediately terminates the programming operation. The Byte Program command sequence should be reinitiated once the device has reset to reading array data, to ensure data integrity. Programming is allowed in any sequence and across sector boundaries. A bit cannot be programmed from a 0 back to a 1. Attempting to do so may halt the operation and set DQ5 to 1, or cause the Data# Polling algorithm to indicate the operation was successful. However, a succeeding read will show that the data is still 0. Only erase operations can convert a 0 to a 1. 10.6 Unlock Bypass Command Sequence The unlock bypass feature allows the system to program bytes or words to the device faster than using the standard program command sequence. The unlock bypass command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle containing the unlock bypass command, 20h. The device then enters the unlock bypass mode. A two-cycle unlock bypass program command sequence is all that is required to program in this mode. The first cycle in this sequence contains the unlock bypass program command, A0h; the second cycle contains the program address and data. Additional data is programmed in the same manner. This mode dispenses with the initial two unlock cycles required in the standard program command sequence, resulting in faster total programming time. Table 10.1 on page 32 shows the requirements for the command sequence. During the unlock bypass mode, only the Unlock Bypass Program and Unlock Bypass Reset commands are valid. To exit the unlock bypass mode, the system must issue the two-cycle unlock bypass reset command sequence. The first cycle must contain the data 90h; the second cycle the data 00h. Addresses are don't care for both cycles. The device then returns to reading array data. Figure 10.1 on page 29 illustrates the algorithm for the program operation. See Erase/Program Operations on page 44 for parameters, and to Figure 17.5 on page 45 for timing diagrams. 28 S29AL016J S29AL016J_00_04 March 25, 2008 Data Sheet (Advance Information) Figure 10.1 Program Operation START Write Program Command Sequence Embedded Program algorithm in progress Data Poll from System Verify Data? No www..com Yes No Increment Address Last Address? Yes Programming Completed Note See Table 10.1 on page 32 for program command sequence. 10.7 Chip Erase Command Sequence Chip erase is a six bus cycle operation. The chip erase command sequence is initiated by writing two unlock cycles, followed by a set-up command. Two additional unlock write cycles are then followed by the chip erase command, which in turn invokes the Embedded Erase algorithm. The device does not require the system to preprogram prior to erase. The Embedded Erase algorithm automatically preprograms and verifies the entire memory for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or timings during these operations. Table 10.1 on page 32 shows the address and data requirements for the chip erase command sequence. Any commands written to the chip during the Embedded Erase algorithm are ignored. Note that a hardware reset during the chip erase operation immediately terminates the operation. The Chip Erase command sequence should be reinitiated once the device has returned to reading array data, to ensure data integrity. The system can determine the status of the erase operation by using DQ7, DQ6, DQ2, or RY/BY#. See Write Operation Status on page 33 for information on these status bits. When the Embedded Erase algorithm is complete, the device returns to reading array data and addresses are no longer latched. Figure 10.2 on page 31 illustrates the algorithm for the erase operation. See Erase/Program Operations on page 44 for parameters, and Figure 17.6 on page 45 for timing diagrams. March 25, 2008 S29AL016J_00_04 S29AL016J 29 Data Sheet (Advance Information) 10.8 Sector Erase Command Sequence Sector erase is a six bus cycle operation. The sector erase command sequence is initiated by writing two unlock cycles, followed by a set-up command. Two additional unlock write cycles are then followed by the address of the sector to be erased, and the sector erase command. Table 10.1 on page 32 shows the address and data requirements for the sector erase command sequence. The device does not require the system to preprogram the memory prior to erase. The Embedded Erase algorithm automatically programs and verifies the sector for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or timings during these operations. After the command sequence is written, a sector erase time-out of 50 s begins. During the time-out period, additional sector addresses and sector erase commands may be written. Loading the sector erase buffer may be done in any sequence, and the number of sectors may be from one sector to all sectors. The time between these additional cycles must be less than 50 s, otherwise the last address and command might not be accepted, and erasure may begin. It is recommended that processor interrupts be disabled during this time to ensure all commands are accepted. The interrupts can be re-enabled after the last Sector Erase command is written. If the time between additional sector erase commands can be assumed to be less than 50 s, the www..com system need not monitor DQ3. Any command other than Sector Erase or Erase Suspend during the time-out period resets the device to reading array data. The system must rewrite the command sequence and any additional sector addresses and commands. The system can monitor DQ3 to determine if the sector erase timer has timed out. (See DQ3: Sector Erase Timer on page 37.) The time-out begins from the rising edge of the final WE# pulse in the command sequence. Once the sector erase operation has begun, only the Erase Suspend command is valid. All other commands are ignored. Note that a hardware reset during the sector erase operation immediately terminates the operation. The Sector Erase command sequence should be reinitiated once the device has returned to reading array data, to ensure data integrity. When the Embedded Erase algorithm is complete, the device returns to reading array data and addresses are no longer latched. The system can determine the status of the erase operation by using DQ7, DQ6, DQ2, or RY/BY#. (Refer to Write Operation Status on page 33 for information on these status bits.) Figure 10.2 on page 31 illustrates the algorithm for the erase operation. Refer to Erase/Program Operations on page 44 for parameters, and to Figure 17.6 on page 45 for timing diagrams. 10.9 Erase Suspend/Erase Resume Commands The Erase Suspend command allows the system to interrupt a sector erase operation and then read data from, or program data to, any sector not selected for erasure. This command is valid only during the sector erase operation, including the 50 s time-out period during the sector erase command sequence. The Erase Suspend command is ignored if written during the chip erase operation or Embedded Program algorithm. Writing the Erase Suspend command during the Sector Erase time-out immediately terminates the time-out period and suspends the erase operation. Addresses are don't-cares when writing the Erase Suspend command. When the Erase Suspend command is written during a sector erase operation, the device requires a maximum of 35 s to suspend the erase operation. However, when the Erase Suspend command is written during the sector erase time-out, the device immediately terminates the time-out period and suspends the erase operation. After the erase operation has been suspended, the system can read array data from or program data to any sector not selected for erasure. (The device "erase suspends" all sectors selected for erasure.) Normal read and write timings and command definitions apply. Reading at any address within erase-suspended sectors produces status data on DQ7-DQ0. The system can use DQ7, or DQ6 and DQ2 together, to determine if a sector is actively erasing or is erase-suspended. See Write Operation Status on page 33 for information on these status bits. After an erase-suspended program operation is complete, the system can once again read array data within non-suspended sectors. The system can determine the status of the program operation using the DQ7 or DQ6 status bits, just as in the standard program operation. See Write Operation Status on page 33 for more information. 30 S29AL016J S29AL016J_00_04 March 25, 2008 Data Sheet (Advance Information) The system may also write the autoselect command sequence when the device is in the Erase Suspend mode. The device allows reading autoselect codes even at addresses within erasing sectors, since the codes are not stored in the memory array. When the device exits the autoselect mode, the device reverts to the Erase Suspend mode, and is ready for another valid operation. See Autoselect Command Sequence on page 27 for more information. The system must write the Erase Resume command (address bits are don't care) to exit the erase suspend mode and continue the sector erase operation. Further writes of the Resume command are ignored. Another Erase Suspend command can be written after the device has resumed erasing.

Write Operation Status The device provides several bits to determine the status of a write operation: DQ2, DQ3, DQ5, DQ6, DQ7, and RY/BY#. Table 11.1 on page 37 and the following subsections describe the functions of these bits. DQ7, RY/BY#, and DQ6 each offer a method for determining whether a program or erase operation is complete or in progress. These three bits are discussed first. 11.1 DQ7: Data# Polling The Data# Polling bit, DQ7, indicates to the host system whether an Embedded Algorithm is in progress or completed, or whether the device is in Erase Suspend. Data# Polling is valid after the rising edge of the final WE# pulse in the program or erase command sequence. During the Embedded Program algorithm, the device outputs on DQ7 the complement of the datum programmed to DQ7. This DQ7 status also applies to programming during Erase Suspend. When the Embedded Program algorithm is complete, the device outputs the datum programmed to DQ7. The system must provide the program address to read valid status information on DQ7. If a program address falls within a www..com protected sector, Data# Polling on DQ7 is active for approximately 1 s, then the device returns to reading array data. During the Embedded Erase algorithm, Data# Polling produces a 0 on DQ7. When the Embedded Erase algorithm is complete, or if the device enters the Erase Suspend mode, Data# Polling produces a 1 on DQ7. This is analogous to the complement/true datum output described for the Embedded Program algorithm: the erase function changes all the bits in a sector to 1; prior to this, the device outputs the complement, or 0. The system must provide an address within any of the sectors selected for erasure to read valid status information on DQ7. After an erase command sequence is written, if all sectors selected for erasing are protected, Data# Polling on DQ7 is active for approximately 100 s, then the device returns to reading array data. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. When the system detects DQ7 has changed from the complement to true data, it can read valid data at DQ7- DQ0 on the following read cycles. This is because DQ7 may change asynchronously with DQ0-DQ6 while Output Enable (OE#) is asserted low. Figure 17.8 on page 46, illustrates this. Table 11.1 on page 37 shows the outputs for Data# Polling on DQ7. Figure 11.2 on page 36 shows the Data# Polling algorithm. March 25, 2008 S29AL016J_00_04 S29AL016J 33 Data Sheet (Advance Information) Figure 11.1 Data# Polling Algorithm START Read DQ7-DQ0 Addr = VA DQ7 = Data? Yes No No www..com DQ5 = 1? Yes Read DQ7-DQ0 Addr = VA DQ7 = Data? Yes No FAIL PASS Notes 1. VA = Valid address for programming. During a sector erase operation, a valid address is an address within any sector selected for erasure. During chip erase, a valid address is any non-protected sector address. 2. DQ7 should be rechecked even if DQ5 = 1 because DQ7 may change simultaneously with DQ5. 11.2 RY/BY#: Ready/Busy# The RY/BY# is a dedicated, open-drain output pin that indicates whether an Embedded Algorithm is in progress or complete. The RY/BY# status is valid after the rising edge of the final WE# pulse in the command sequence. Since RY/BY# is an open-drain output, several RY/BY# pins can be tied together in parallel with a pull-up resistor to VCC. If the output is low (Busy), the device is actively erasing or programming. (This includes programming in the Erase Suspend mode.) If the output is high (Ready), the device is ready to read array data (including during the Erase Suspend mode), or is in the standby mode. Table 11.1 on page 37 shows the outputs for RY/BY#. Figures Figure 17.1 on page 41, Figure 17.2 on page 42, Figure 17.5 on page 45 and Figure 17.6 on page 45 shows RY/BY# for read, reset, program, and erase operations, respectively. 34 S29AL016J S29AL016J_00_04 March 25, 2008 Data Sheet (Advance Information) 11.3 DQ6: Toggle Bit I Toggle Bit I on DQ6 indicates whether an Embedded Program or Erase algorithm is in progress or complete, or whether the device has entered the Erase Suspend mode. Toggle Bit I may be read at any address, and is valid after the rising edge of the final WE# pulse in the command sequence (prior to the program or erase operation), and during the sector erase time-out. During an Embedded Program or Erase algorithm operation, successive read cycles to any address cause DQ6 to toggle. (The system may use either OE# or CE# to control the read cycles.) When the operation is complete, DQ6 stops toggling. After an erase command sequence is written, if all sectors selected for erasing are protected, DQ6 toggles for approximately 100 s, then returns to reading array data. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. The system can use DQ6 and DQ2 together to determine whether a sector is actively erasing or is erasesuspended. When the device is actively erasing (that is, the Embedded Erase algorithm is in progress), DQ6 www..com toggles. When the device enters the Erase Suspend mode, DQ6 stops toggling. However, the system must also use DQ2 to determine which sectors are erasing or erase-suspended. Alternatively, the system can use DQ7 (see DQ7: Data# Polling on page 33). If a program address falls within a protected sector, DQ6 toggles for approximately 1 s after the program command sequence is written, then returns to reading array data. DQ6 also toggles during the erase-suspend-program mode, and stops toggling once the Embedded Program algorithm is complete. Table 11.1 on page 37 shows the outputs for Toggle Bit I on DQ6. Figure 11.2 on page 36 shows the toggle bit algorithm in flowchart form, and Reading Toggle Bits DQ6/DQ2 on page 36 explains the algorithm. Figure 17.9 on page 47 shows the toggle bit timing diagrams. Figure 17.10 on page 47 shows the differences between DQ2 and DQ6 in graphical form. See also the subsection on DQ2: Toggle Bit II on page 35. 11.4 DQ2: Toggle Bit II The "Toggle Bit II" on DQ2, when used with DQ6, indicates whether a particular sector is actively erasing (that is, the Embedded Erase algorithm is in progress), or whether that sector is erase-suspended. Toggle Bit II is valid after the rising edge of the final WE# pulse in the command sequence. DQ2 toggles when the system reads at addresses within those sectors that have been selected for erasure. (The system may use either OE# or CE# to control the read cycles.) But DQ2 cannot distinguish whether the sector is actively erasing or is erase-suspended. DQ6, by comparison, indicates whether the device is actively erasing, or is in Erase Suspend, but cannot distinguish which sectors are selected for erasure. Thus, both status bits are required for sector and mode information. Refer to Table 11.1 on page 37 to compare outputs for DQ2 and DQ6. Figure 11.2 on page 36 shows the toggle bit algorithm in flowchart form, and the section Reading Toggle Bits DQ6/DQ2 on page 36 explains the algorithm. See also the DQ6: Toggle Bit I on page 35 subsection. Figure 17.9 on page 47 shows the toggle bit timing diagram. Figure 17.10 on page 47 shows the differences between DQ2 and DQ6 in graphical form. March 25, 2008 S29AL016J_00_04 S29AL016J 35 Data Sheet (Advance Information) 11.5 Reading Toggle Bits DQ6/DQ2 Refer to Figure 11.2 on page 36 for the following discussion. Whenever the system initially begins reading toggle bit status, it must read DQ7-DQ0 at least twice in a row to determine whether a toggle bit is toggling. Typically, the system would note and store the value of the toggle bit after the first read. After the second read, the system would compare the new value of the toggle bit with the first. If the toggle bit is not toggling, the device has completed the program or erase operation. The system can read array data on DQ7-DQ0 on the following read cycle. However, if after the initial two read cycles, the system determines that the toggle bit is still toggling, the system also should note whether the value of DQ5 is high (see the section on DQ5). If it is, the system should then determine again whether the toggle bit is toggling, since the toggle bit may have stopped toggling just as DQ5 went high. If the toggle bit is no longer toggling, the device has successfully completed the program or erase operation. If it is still toggling, the device did not complete the operation successfully, and the system must write the reset command to return to reading array data. The remaining scenario is that the system initially determines that the toggle bit is toggling and DQ5 has not gone high. The system may continue to monitor the toggle bit and DQ5 through successive read cycles, www..com determining the status as described in the previous paragraph. Alternatively, it may choose to perform other system tasks. In this case, the system must start at the beginning of the algorithm when it returns to determine the status of the operation (top of Figure 11.2 on page 36). Figure 11.2 Toggle Bit Algorithm START (Note 1) Read DQ7-DQ0 Read DQ7-DQ0 Toggle Bit = Toggle? Yes No No DQ5 = 1? Yes (Notes 1, 2) Read DQ7-DQ0 Twice Toggle Bit = Toggle? No Yes Program/Erase Operation Not Complete, Write Reset Command Notes 1. Read toggle bit twice to determine whether or not it is toggling. See text. 2. Recheck toggle bit because it may stop toggling as DQ5 changes to 1. See text. Program/Erase Operation Complete 36 S29AL016J S29AL016J_00_04 March 25, 2008 Data Sheet (Advance Information) 11.6 DQ5: Exceeded Timing Limits DQ5 indicates whether the program or erase time has exceeded a specified internal pulse count limit. Under these conditions DQ5 produces a 1. This is a failure condition that indicates the program or erase cycle was not successfully completed. The DQ5 failure condition may appear if the system tries to program a 1 to a location that is previously programmed to 0. Only an erase operation can change a 0 back to a 1. Under this condition, the device halts the operation, and when the operation has exceeded the timing limits, DQ5 produces a 1. Under both these conditions, the system must issue the reset command to return the device to reading array data. 11.7 DQ3: Sector Erase Timer After writing a sector erase command sequence, the system may read DQ3 to determine whether or not an erase operation has begun. (The sector erase timer does not apply to the chip erase command.) If additional sectors are selected for erasure, the entire time-out also applies after each additional sector erase command. www..com When the time-out is complete, DQ3 switches from 0 to 1. The system may ignore DQ3 if the system can guarantee that the time between additional sector erase commands will always be less than 50 s. See also Sector Erase Command Sequence on page 30. After the sector erase command sequence is written, the system should read the status on DQ7 (Data# Polling) or DQ6 (Toggle Bit I) to ensure the device has accepted the command sequence, and then read DQ3. If DQ3 is 1, the internally controlled erase cycle has begun; all further commands (other than Erase Suspend) are ignored until the erase operation is complete. If DQ3 is 0, the device will accept additional sector erase commands. To ensure the command has been accepted, the system software should check the status of DQ3 prior to and following each subsequent sector erase command. If DQ3 is high on the second status check, the last command might not have been accepted. Table 11.1 shows the outputs for DQ3.
