MXIC's Flash memories offer the most cost-effective and reliable read/write nonvolatile random access memory. The MX29LV065 is packaged in 48-pin TSOP and 63-ball CSP. It is designed to be reprogrammed and erased in system or in standard EPROM programmers. The standard MX29LV065 offers access time as fast as 90ns, allowing operation of high-speed microprocessors without wait states. To eliminate bus contention, the MX29LV065 has separate chip enable (CE) and output enable (OE) controls. MXIC's Flash memories augment EPROM functionality P/N:PM0893 REV. 0.4, JUL. 22, 2003 1 MX29LV065 with in-circuit electrical erasure and programming. The MX29LV065 uses a command register to manage this functionality. MXIC Flash technology reliably stores memory contents even after 100,000 erase and program cycles. The MXIC cell is designed to optimize the erase and program mechanisms. In addition, the combination of advanced tunnel oxide processing and low internal electric fields for erase and programming operations produces reliable cycling. The MX29LV065 uses a 3.0V to 3.6V VCC supply to perform the High Reliability Erase and auto Program/Erase algorithms. The highest degree of latch-up protection is achieved with MXIC's proprietary non-epi process. Latch-up protection is proved for stresses up to 100 milliamps on address and data pin from -1V to VCC + 1V. AUTOMATIC SECTOR ERASE The MX29LV065 is sector(s) erasable using MXIC's Auto Sector Erase algorithm. Sector erase modes allow sectors of the array to be erased in one erase cycle. The Automatic Sector Erase algorithm automatically programs the specified sector(s) prior to electrical erase. The timing and verification of electrical erase are controlled internally within the device. AUTOMATIC ERASE ALGORITHM MXIC's Automatic Erase algorithm requires the user to write commands to the command register using standard microprocessor write timings. The device will automatically pre-program and verify the entire array. Then the device automatically times the erase pulse width, provides the erase verification, and counts the number of sequences. A status bit toggling between consecutive read cycles provides feedback to the user as to the status of the programming operation. Register contents serve as inputs to an internal statemachine which controls the erase and programming circuitry. During write cycles, the command register internally latches address and data needed for the programming and erase operations. During a system write cycle, addresses are latched on the falling edge, and data are latched on the rising edge of WE . MXIC's Flash technology combines years of EPROM experience to produce the highest levels of quality, reliability, and cost effectiveness. The MX29LV065 electrically erases all bits simultaneously using Fowler-Nordheim tunneling. The bytes are programmed by using the EPROM programming mechanism of hot electron injection. During a program cycle, the state-machine will control the program sequences and command register will not respond to any command set. During a Sector Erase cycle, the command register will only respond to Erase Suspend command. After Erase Suspend is completed, the device stays in read mode. After the state machine has completed its task, it will allow the command register to respond to its full command set. AUTOMATIC PROGRAMMING The MX29LV065 is byte programmable using the Automatic Programming algorithm. The Automatic Programming algorithm makes the external system do not need to have time out sequence nor to verify the data programmed. The typical chip programming time at room temperature of the MX29LV065 is less than 42sec. AUTOMATIC PROGRAMMING ALGORITHM MXIC's Automatic Programming algorithm require the user to only write program set-up commands (including 2 unlock write cycle and A0H) and a program command (program data and address). The device automatically times the programming pulse width, provides the program verification, and counts the number of sequences. A status bit similar to DATA polling and a status bit toggling between consecutive read cycles, provide feedback to the user as to the status of the programming operation. AUTOMATIC CHIP ERASE The entire chip is bulk erased using 50 ms erase pulses according to MXIC's Automatic Chip Erase algorithm. Typical erasure at room temperature is accomplished in less than 205 seconds. The Automatic Erase algorithm automatically programs the entire array prior to electrical erase. The timing and verification of electrical erase are controlled internally within the device.

P/N:PM0893 REV. 0.4, JUL. 22, 2003 12 MX29LV065 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 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 address 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. STANDBY MODE MX29LV065 can be set into Standby mode with two different approaches. One is using both CE and RESET pins and the other one is using RESET pin only. When using both pins of CE and RESET, a CMOS Standby mode is achieved with both pins held at Vcc 0.3V. Under this condition, the current consumed is less than 0.2uA (typ.). If both of the CE and RESET are held at VIH, but not within the range of VCC 0.3V, the device will still be in the standby mode, but the standby current will be larger. During Auto Algorithm operation, Vcc active current (Icc2) is required even CE = "H" until the operation is completed. The device can be read with standard access time (tCE) from either of these standby modes. When using only RESET, a CMOS standby mode is achieved with RESET input held at Vss 0.3V, Under this condition the current is consumed less than 1uA (typ.). Once the RESET pin is taken high, the device is back to active without recovery delay. In the standby mode the outputs are in the high impedance state, independent of the OE input. MX29LV065 is capable to provide the Automatic Standby Mode to restrain power consumption during read-out of data. This mode can be used effectively with an application requested low power consumption such as handy terminals. To active this mode, MX29LV065 automatically switch themselves to low power mode when MX29LV065 addresses remain stable during access time of tACC+30ns. It is not necessary to control CE, WE, and OE on the mode. Under the mode, the current consumed is typically 0.2uA (CMOS level). WRITE COMMANDS/COMMAND SEQUENCES To program data to the device or erase sectors of memory , the system must drive WE and CE to VIL, and OE to VIH. An erase operation can erase one sector, multiple sectors , or the entire device. Table indicates the address space that each sector occupies. A "sector address" consists of the address bits required to uniquely select a sector. The "Writing specific address and data commands or sequences into the command register initiates device operations. Table 1 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". Section has details on erasing a sector or the entire chip, or suspending/resuming the erase operation. After the system writes the auto-select command sequence, the device enters the auto-select mode. The system can then read auto-select codes from the internal register (which is separate from the memory array) on Q7-Q0. Standard read cycle timings apply in this mode. Refer to the Auto-select Mode and Auto-select Command Sequence section for more information. ICC2 in the DC Characteristics table represents the active current specification for the write mode. The "AC Characteristics" section contains timing specification table and timing diagrams for write operations. AUTOMATIC SLEEP MODE The automatic sleep mode minimizes Flash device energy consumption. The device automatically enables this mode when address remain stable for tACC+30ns. 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 table represents the automatic sleep mode current specification. REV. 0.4, JUL. 22, 2003 P/N:PM0893 13 MX29LV065 OUTPUT DISABLE With the OE input at a logic high level (VIH), output from the devices are disabled. This will cause the output pins to be in a high impedance state. force VID on address pin A9 and control pin OE, (suggest VID = 12V) A6 = VIL and CE = VIL. (see Table 2) Programming of the protection circuitry begins on the falling edge of the WE pulse and is terminated on the rising edge. Please refer to sector group protect algorithm and waveform. MX29LV065 also provides another method. Which requires VID on the RESET only. This method can be implemented either in-system or via programming equipment. This method uses standard microprocessor bus cycle timing. To verify programming of the protection circuitry, the programming equipment must force VID on address pin A9 ( with CE and OE at VIL and WE at VIH). When A1=1, it will produce a logical "1" code at device output Q0 for a protected sector. Otherwise the device will produce 00H for the unprotected sector. In this mode, the addresses, except for A1, are don't care. Address locations with A1 = VIL are reserved to read manufacturer and device codes. (Read Silicon ID) It is also possible to determine if the group is protected in the system by writing a Read Silicon ID command. Performing a read operation with A1=VIH, it will produce a logical "1" at Q0 for the protected sector. RESET OPERATION The RESET pin provides a hardware method of resetting the device to reading array data. When the RESET pin is driven low for at least a period of tRP, the device immediately terminates any operation in progress, tristates all output pins, and ignores all read/write commands 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 Current is reduced for the duration of the RESET pulse. When RESET is held at VSS0.3V, the device draws CMOS standby current (ICC4). If RESET is held at VIL but not within VSS0.3V, the standby current will be greater. The RESET pin may be tied to system reset circuitry. A system reset would that 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 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 AC Characteristics tables for RESET parameters and to Figure 14 for the timing diagram. CHIP UNPROTECTED OPERATION The MX29LV065 also features the chip unprotected mode, so that all sectors are unprotected after chip unprotected is completed to incorporate any changes in the code. It is recommended to protect all sectors before activating chip unprotected mode. To activate this mode, the programming equipment must force VID on control pin OE and address pin A9. The CE pins must be set at VIL. Pins A6 must be set to VIH. (see Table 2) Refer to chip unprotected algorithm and waveform for the chip unprotected algorithm. The unprotected mechanism begins on the falling edge of the WE pulse and is terminated on the rising edge. MX29LV065 also provides another method. Which requires VID on the RESET only. This method can be implemented either in-system or via programming equipment. This method uses standard microprocessor bus cycle timing. It is also possible to determine if the chip is unprotected in the system by writing the Read Silicon ID command. Performing a read operation with A1=VIH, it will produce 00H at data outputs(Q0-Q7) for an unprotected sector. It REV. 0.4, JUL. 22, 2003 SECTOR GROUP PROTECT OPERATION The MX29LV065 features hardware sector group protection. This feature will disable both program and erase operations for these sector group protected. In this device, a sector group consists of four adjacent sectors which are protected or unprotected at the same time. To activate this mode, the programming equipment must P/N:PM0893 14 MX29LV065 is noted that all sectors are unprotected after the chip unprotected algorithm is completed. TEMPORARY SECTOR GROUP UNPROTECTED OPERATION This feature allows temporary unprotected of previously protected sector to change data in-system. The Temporary Sector Unprotected mode is activated by setting the RESET pin to VID(11.5V-12.5V). During this mode, formerly protected sectors can be programmed or erased as unprotected sector. Once VID is remove from the RESET pin, all the previously protected sectors are protected again. SILICON ID READ OPERATION Flash memories are intended for use in applications where the local CPU alters memory contents. As such, manufacturer and device codes must be accessible while the device resides in the target system. PROM programmers typically access signature codes by raising A9 to a high voltage. However, multiplexing high voltage onto address lines is not generally desired system design practice. MX29LV065 provides hardware method to access the silicon ID read operation. Which method requires VID on A9 pin, VIL on CE, OE, A6, and A1 pins. Which apply VIL on A0 pin, the device will output MXIC's manufacture code of C2H. Which apply VIH on A0 pin, the device will output MX29LV065 device code of 93H.

During power up the device automatically resets the state machine in the Read mode. In addition, with its control register architecture, alteration of the memory contents only occurs after successful completion of specific command sequences. The device also incorporates several features to prevent inadvertent write cycles resulting from VCC power-up and power-down transition or system noise. uct is shipped to the field. The MX29LV065 offers the device with 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 customerlockable version is shipped with the Secured Silicon Sector unprotected, allowing customs to utilize that sector in any form they prefer. The customer-lockable version has the secured sector Indicator Bit permanently set to a "0". Therefore, the Secured Silicon Sector Indicator Bit permanently set to a "0". Therefore, the Second Silicon Sector Indicator Bit prevents customer, lockable device from being used to replace devices that are factory locked. The system access the Secured Silicon Sector through a command sequence (refer to "Enter Secured Silicon/ Exit Secured Silicon Sector command Sequence). After the system has written the Enter Secured Silicon Sector command sequence, it may read the Secured Silicon Sector by using the address normally occupied by the first sector (SA0). 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 command to sector SA0. SECURED SILICON SECTOR The MX29LV065 features a Flash memory region where the system may access through a command sequence to create a permanent part identification as so called Electronic Serial Number (ESN) in the device. Once this region is programmed, any further modification on the region is impossible. The secured silicon sector is a 128 words in length, and uses a Secured Silicon Sector Indicator Bit (Q7) 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 prevent duplication of a factory locked part. This ensures the security of the ESN once the prodP/N:PM0893 REV. 0.4, JUL. 22, 2003 16 MX29LV065 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 write when VCC is greater than VLKO. FACTORY LOCKED:Secured Silicon Sector Programmed and Protected At the Factory In device with an ESN, the Secured Silicon Sector is protected when the device is shipped from the factory. The Secured Silicon Sector cannot be modified in any way. A factory locked device has an 16-byte random ESN at address 000000h-00000Fh. WRITE PULSE "GLITCH" PROTECTION Noise pulses of less than 5ns(typical) on CE or WE will not initiate a write cycle. CUSTOMER LOCKABLE:Secured Silicon Sector NOT Programmed or Protected At the Factory As an alternative to the factory-locked version, the device may be ordered such that the customer may program and protect the 256-byte Secured Silicon Sector. Programming and protecting the Secured Silicon Sector must be used with caution since, once protected, there is no procedure available for unprotected the Secured Silicon Sector area and none of the bits in the Secured Silicon Sector memory space can be modified in any way. The Secured Silicon Sector area can be protected using one of the following procedures: Write the three-cycle Enter Secured Silicon Sector Region command sequence, and then follow the in-system sector protect algorithm as shown in Figure 2, except that RESET may be at either VIH or VID. This allows insystem protection of the Secured Silicon Sector without raising any device pin to a high voltage. Note that method is only applicable to the Secured Silicon Sector. Write the three-cycle Enter Secured Silicon Sector Region command sequence, and then alternate method of sector protection described in the :Sector Group Protection and Unprotected" section. Once the Secured Silicon Sector is programmed, 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. LOGICAL INHIBIT Writing is 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. POWER-UP SEQUENCE The MX29LV065 powers up in the Read only mode. In addition, the memory contents may only be altered after successful completion of the predefined command sequences. POWER-UP WRITE INHIBIT In order to reduce power switching effect, each device should have a 0.1uF ceramic capacitor connected between its VCC and GND. POWER SUPPLY DE COUPLING In order to reduce power switching effect, each device should have a 0.1uF ceramic capacitor connected between its VCC and GND. P/N:PM0893 REV. 0.4, JUL. 22, 2003 17 MX29LV065 SOFTWARE COMMAND DEFINITIONS Device operations are selected by writing specific address and data sequences into the command register. Writing incorrect address and data values or writing them in the improper sequence will reset the device to the read mode. Table 2 defines the valid register command sequences. Note that the Erase Suspend (B0H) and Erase Resume (30H) commands are valid only while the Sector Erase operation is in progress. Either of the two reset command sequences will reset the device(when applicable). All addresses are latched on the falling edge of WE or CE, whichever happens later.

Command is valid when device is ready to read array data or when device is in auto-select mode. 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 Automatic Program or Automatic 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 erasesuspended 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 rase Suspend/Erase Resume Commands" for more information on this mode. The system must issue the reset command to re-enable the device for reading array data if Q5 goes high, or while in the auto-select mode. See the "Reset Command" section, next. 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 SILICON ID READ command sequence. Once in the SILICON ID READ mode, the reset command must be written to return to reading array data (also applies to SILICON ID READ during Erase Suspend). If Q5 goes high during a program or erase operation, writing the reset command returns the device to reading array data (also applies during Erase Suspend). 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 SILICON ID READ COMMAND SEQUENCE The SILICON ID READ command sequence allows the host system to access the manufacturer and devices codes, and determine whether or not a sector is protected. Table 2 shows the address and data requirements. P/N:PM0893 REV. 0.4, JUL. 22, 2003 19 MX29LV065 This method is an alternative to that shown in Table 1, which is intended for PROM programmers and requires VID on address bit A9. The SILICON ID READ command sequence is initiated by writing two unlock cycles, followed by the SILICON ID READ command. The device then enters the SILICON ID READ 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 returns 01h if that sector is protected, or 00h if it is unprotected. Refer to Table for valid sector addresses. The system must write the reset command to exit the auto-select mode and return to reading array data. BYTE PROGRAM COMMAND SEQUENCE The command sequence requires four bus cycles, and 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. The device automatically generates the program pulses and verifies the programmed cell margin. Table 1 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 Q7, Q6, or RY/BY. See "Write Operation Status" 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 Q5 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". P/N:PM0893 REV. 0.4, JUL. 22, 2003 20 MX29LV065 SETUP AUTOMATIC CHIP/SECTOR ERASE Chip erase is a six-bus cycle operation. There are two "unlock" write cycles. These are followed by writing the "set-up" command 80H. Two more "unlock" write cycles are then followed by the chip erase command 10H, or the sector erase command 30H. The MX29LV065 contains a Silicon-ID-Read operation to supplement traditional PROM programming methodology. The operation is initiated by writing the read silicon ID command sequence into the command register. Following the command write, a read cycle with A1=VIL,A0=VIL retrieves the manufacturer code of C2H. A read cycle with A1=VIL, A0=VIH returns the device code of 93H for MX29LV065. TABLE 3. SILICON ID CODE Pins Manufacture code Device code for MX29LV065 A0 VIL VIH A1 VIL VIL Q7 1 1 Q6 1 0 Q5 0 1 Q4 0 0 Q3 0 0 Q2 0 0 Q1 1 1 Q0 0 1 Code(Hex) C2H 93H AUTOMATIC CHIP/SECTOR ERASE COMMAND The device does not require the system to preprogram prior to erase. The Automatic Erase algorithm automatically preprogram 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 2 shows the address and data requirements for the chip erase command sequence. Any commands written to the chip during the Automatic 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 Q7, Q6, Q2, or RY/BY. See "Write Operation Status" for information on these status bits. When the Automatic Erase algorithm is complete, the device returns to reading array data and addresses are no longer latched. Figure 3 illustrates the algorithm for the erase operation. See the Erase/Program Operations tables in "AC Characteristics" for parameters, and to Figure 16 for timing diagrams. SECTOR ERASE COMMANDS The Automatic Sector Erase does not require the device to be entirely pre-programmed prior to executing the Automatic Set-up Sector Erase command and Automatic Sector Erase command. Upon executing the Automatic Sector Erase command, the device will automatically program and verify the sector(s) memory for an all-zero data pattern. The system is not required to provide any control or timing during these operations. When the sector(s) is automatically verified to contain an all-zero pattern, a self-timed sector erase and verify begin. The erase and verify operations are complete when the data on Q7 is "1" and the data on Q6 stops toggling for two consecutive read cycles, at which time the device returns to the Read mode. The system is not required to provide any control or timing during these operations. When using the Automatic Sector Erase algorithm, note that the erase automatically terminates when adequate erase margin has been achieved for the memory array (no erase verification command is required). Sector erase is a six-bus cycle operation. There are two "unlock" write cycles. These are followed by writing the set-up command 80H. Two more "unlock" write cycles are then followed by the sector erase command 30H. The sector address is latched on the falling edge of WE or CE, whichever P/N:PM0893 REV. 0.4, JUL. 22, 2003 21 MX29LV065 happens later , while the command(data) is latched on the rising edge of WE or CE, whichever happens first. Sector addresses selected are loaded into internal register on the sixth falling edge of WE or CE, whichever happens later. Each successive sector load cycle started by the falling edge of WE or CE, whichever happens later must begin within 50us from the rising edge of the preceding WE or CE, whichever happens first. Otherwise, the loading period ends and internal auto sector erase cycle starts. (Monitor Q3 to determine if the sector erase timer window is still open, see section Q3, Sector Erase Timer.) Any command other than Sector Erase(30H) or Erase Suspend(B0H) during the time-out period resets the device to read mode. QUERY COMMAND AND COMMON FLASH INTERFACE (CFI) MODE MX29LV065 is capable of operating in the CFI mode. This mode all the host system to determine the manufacturer of the device such as operating parameters and configuration. Two commands are required in CFI mode. Query command of CFI mode is placed first, then the Reset command exits CFI mode. These are described in Table 3. The single cycle Query command is valid only when the device is in the Read mode, including Erase Suspend, Standby mode, and Read ID mode; however, it is ignored otherwise. The Reset command exits from the CFI mode to the Read mode, or Erase Suspend mode, or read ID mode. The command is valid only when the device is in the CFI mode. ERASE SUSPEND This command only has meaning while the state machine is executing Automatic Sector Erase operation, and therefore will only be responded during Automatic Sector Erase operation. When the Erase Suspend command is issued during the sector erase operation, the device requires a maximum 20us to suspend the sector 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 this command has been executed, the command register will initiate erase suspend mode. The state machine will return to read mode automatically after suspend is ready. At this time, state machine only allows the command register to respond to the Erase Resume, program data to, or read data from any sector not selected for erasure. The system can determine the status of the program operation using the Q7 or Q6 status bits, just as in the standard program operation. After an erase-suspend program operation is complete, the system can once again read array data within non-suspended blocks. ERASE RESUME This command will cause the command register to clear the suspend state and return back to Sector Erase mode but only if an Erase Suspend command was previously issued. Erase Resume will not have any effect in all other conditions. Another Erase Suspend command can be written after the chip has resumed erasing.

However, successive reads from the erase-suspended sector will cause Q2 to toggle. P/N:PM0893 REV. 0.4, JUL. 22, 2003 25 MX29LV065 Q7: Data Polling The Data Polling bit, Q7, indicates to the host system whether an Automatic 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 Automatic Program algorithm, the device outputs on Q7 the complement of the datum programmed to Q7. This Q7 status also applies to programming during Erase Suspend. When the Automatic Program algorithm is complete, the device outputs the datum programmed to Q7. The system must provide the program address to read valid status information on Q7. If a program address falls within a protected sector, Data Polling on Q7 is active for approximately 1 us, then the device returns to reading array data. During the Automatic Erase algorithm, Data Polling produces a "0" on Q7. When the Automatic Erase algorithm is complete, or if the device enters the Erase Suspend mode, Data Polling produces a "1" on Q7. This is analogous to the complement/true datum output described for the Automatic 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 Q7. After an erase command sequence is written, if all sectors selected for erasing are protected, Data Polling on Q7 is active for approximately 100 us, then the device returns to reading array data. If not all selected sectors are protected, the Automatic Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. When the system detects Q7 has changed from the complement to true data, it can read valid data at Q7-Q0 on the following read cycles. This is because Q7 may change asynchronously with Q0-Q6 while Output Enable (OE) is asserted low. after the rising edge of the final WE or CE, whichever happens first pulse in the command sequence (prior to the program or erase operation), and during the sector time-out. During an Automatic Program or Erase algorithm operation, successive read cycles to any address cause Q6 to toggle. The system may use either OE or CE to control the read cycles. When the operation is complete, Q6 stops toggling. After an erase command sequence is written, if all sectors selected for erasing are protected, Q6 toggles for 100us and returns to reading array data. If not all selected sectors are protected, the Automatic Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. The system can use Q6 and Q2 together to determine whether a sector is actively erasing or is erase suspended. When the device is actively erasing (that is, the Automatic Erase algorithm is in progress), Q6 toggling. When the device enters the Erase Suspend mode, Q6 stops toggling. However, the system must also use Q2 to determine which sectors are erasing or erase-suspended. Alternatively, the system can use Q7. If a program address falls within a protected sector, Q6 toggles for approximately 2us after the program command sequence is written, then returns to reading array data. Q6 also toggles during the erase-suspend-program mode, and stops toggling once the Automatic Program algorithm is complete. Table 4 shows the outputs for Toggle Bit I on Q6. Q2:Toggle Bit II The "Toggle Bit II" on Q2, when used with Q6, indicates whether a particular sector is actively erasing (that is, the Automatic Erase algorithm is in process), or whether that sector is erase-suspended. Toggle Bit II is valid after the rising edge of the final WE or CE, whichever happens first pulse in the command sequence. Q2 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 Q6:Toggle BIT I Toggle Bit I on Q6 indicates whether an Automatic 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 P/N:PM0893 REV. 0.4, JUL. 22, 2003 26 MX29LV065 cycles.) But Q2 cannot distinguish whether the sector is actively erasing or is erase-suspended. Q6, 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 sectors and mode information. Refer to Table 4 to compare outputs for Q2 and Q6. only operating functions of the device under this condition. If this time-out condition occurs during sector erase operation, it specifies that a particular sector is bad and it may not be reused. However, other sectors are still functional and may be used for the program or erase operation. The device must be reset to use other sectors. Write the Reset command sequence to the device, and then execute program or erase command sequence. This allows the system to continue to use the other active sectors in the device. If this time-out condition occurs during the chip erase operation, it specifies that the entire chip is bad or combination of sectors are bad. If this time-out condition occurs during the byte programming operation, it specifies that the entire sector containing that byte is bad and this sector may not be reused, (other sectors are still functional and can be reused). The time-out condition may also appear if a user tries to program a non blank location without erasing. In this case the device locks out and never completes the Automatic Algorithm operation. Hence, the system never reads a valid data on Q7 bit and Q6 never stops toggling. Once the Device has exceeded timing limits, the Q5 bit will indicate a "1". Please note that this is not a device failure condition since the device was incorrectly used. The Q5 failure condition may appear if the system tries to program a to a "1" 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, Q5 produces a "1". Reading Toggle Bits Q6/ Q2 Whenever the system initially begins reading toggle bit status, it must read Q7-Q0 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 Q7-Q0 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 Q5 is high (see the section on Q5). 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 Q5 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 system initially determines that the toggle bit is toggling and Q5 has not gone high. The system may continue to monitor the toggle bit and Q5 through successive read cycles, 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. Q3:Sector Erase Timer After the completion of the initial sector erase command sequence, the sector erase time-out will begin. Q3 will remain low until the time-out is complete. Data Polling and Toggle Bit are valid after the initial sector erase command sequence. If Data Polling or the Toggle Bit indicates the device has been written with a valid erase command, Q3 may be used to determine if the sector erase timer window is Q5:Program/Erase Timing Q5 will indicate if the program or erase time has exceeded the specified limits (internal pulse count). Under these conditions Q5 will produce a "1". This time-out condition indicates that the program or erase cycle was not successfully completed. Data Polling and Toggle Bit are the P/N:PM0893 REV. 0.4, JUL. 22, 2003 27 MX29LV065 still open. If Q3 is high ("1") the internally controlled erase cycle has begun; attempts to write subsequent commands to the device will be ignored until the erase operation is completed as indicated by Data Polling or Toggle Bit. If Q3 is low ("0"), the device will accept additional sector erase commands. To insure the command has been accepted, the system software should check the status of Q3 prior to and following each subsequent sector erase command. If Q3 were high on the second status check, the command may not have been accepted. If the time between additional erase commands from the system can be less than 50us, the system need not to monitor Q3. RY/BY:READY/BUSY OUTPUT 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.
