GENERAL DESCRIPTION
The MX29F002T/B is a 2-mega bit Flash memory organized as 256K bytes of 8 bits only. MXIC's Flash memories offer the most cost-effective and reliable read/write nonvolatile random access memory. The MX29F002T/B is packaged in 32-pin PDIP,PLCC and 32-pin TSOP(I). It is designed to be reprogrammed and erased in-system or instandard EPROM programmers. The standard MX29F002T/B offers access time as fast as 55ns, allowing operation of high-speed microprocessors without wait states. To eliminate bus contention, the MX29F002T/B has separate chip enable (CE) and output enable (OE) controls. MXIC's Flash memories augment EPROM functionality with in-circuit electrical erasure and programming. The MX29F002T/B uses a command register to manage this functionality. The command register allows for 100% TTL level control inputs and fixed power supply levels during erase and programming, while maintaining maximum EPROM compatibility. MXIC's Flash technology reliably stores memory contents even after 100,000 erase and program cycles. The MXIC cell is designed to optimize the erase and programming mechanisms. In addition, the combination of advanced tunnel oxide processing and low internal electric fields for erase and programming operations produces reliable cycling. The MX29F002T/B uses a 5.0V 10% 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 PROGRAMMING
The MX29F002T/B is byte programmable using the Automatic Programming algorithm. The Automatic Programming algorithm does not require the system to time out or verify the data programmed. The typical chip programming time of the MX29F002T/B at room temperature is less than 3.5 seconds.
cally pre-program and verify the entire array. Then the device automatically times the erase pulse width, verifies the erase, and counts the number of sequences. A status bit similar to DATA polling and status bit toggling between consecutive read cycles provides feedback to the user as to the status of the programming operation. Commands are written to the command register using standard microprocessor write timings. Register contents serve as inputs to an internal state-machine 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 MX29F002T/B electrically erases all bits simultaneously using Fowler-Nordheim tunneling. The bytes are programmed one byte at a time 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 CHIP ERASE
Typical erasure at room temperature is accomplished in less than 3 seconds. The device is erased using the Automatic Erase algorithm. The Automatic Erase algorithm automatically programs the entire array prior to electrical erase. The timing and verification of electrical erase are internally controlled by the device.
AUTOMATIC SECTOR ERASE
The MX29F002T/B 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 internally controlled by the device.
AUTOMATIC PROGRAMMING ALGORITHM
MXIC's Automatic Programming algorithm requires the user to only write a program set-up commands include 2 unlock write cycle and A0H and a program command (program data and address). The device automatically times the programming pulse width, verifies the program, and counts the number of sequences. A status bit similar to DATA polling and a status bit toggling between consecutive read cycles, provides feedback to the user as to the status of the programming operation.

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 1 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).

MX29F002/002N T/B
READ/RESET COMMAND
The read or reset operation is initiated by writing the read/ reset command sequence into the command register. Microprocessor read cycles retrieve array data. The device remains enabled for reads until the command register contents are altered. If program-fail or erase-fail happen, the write of F0H will reset the device to abort the operation. A valid command must then be written to place the device in the desired state.
SET-UP AUTOMATIC CHIP/SECTOR ERASE COMMANDS
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. The Automatic Chip Erase does not require the device to be entirely pre-programmed prior to executing the Automatic Chip Erase. Upon executing the Automatic Chip Erase, the device will automatically program and verify the entire memory for an all-zero data pattern. When the device is automatically verified to contain an all-zero pattern, a selftimed chip erase and verify begin. The erase and verify operations are completed when the data on Q7 is "1" 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 Chip Erase algorithm, note that the erase automatically terminates when adequate erase margin has been achieved for the memory array(no erase verify command is required). If the Erase operation was unsuccessful, the data on Q5 is "1" (see Table 4), indicating the erase operation exceed internal timing limit. The automatic erase begins on the rising edge of the last WE pulse in the command sequence and terminates 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.
SILICON-ID-READ COMMAND
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. The MX29F002T/B 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 B0h for MX29F002T, 34h for MX29F002B.

SET-UP AUTOMATIC COMMANDS
SECTOR
ERASE
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 does not require 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 verification begin. The erase and verification 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 does 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 verify command is required). Sector erase is a sixbus 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, while the command(data) is latched on the rising edge of WE. Sector addresses selected are loaded into internal register on the sixth falling edge of WE. Each successive sector load cycle started by the falling edge of WE must begin within 30us from the rising edge of the preceding WE. 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 (BOH) during the time-out period resets the device to read mode.
the Sector Erase time-out 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 Read Memory Array, Erase Resume and Program commands. 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-suspended program operation is complete, the system can once again read array data within nonsuspended sectors.
ERASE SUSPEND
This command is only valid while the state machine is executing Automatic Sector Erase operation, and therefore will only be responded during Automatic Sector Erase operation. Writing the Erase Suspend command during

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.
fourth WE pulse of the four write pulse sequences for automatic program. While the Automatic Erase algorithm is in operation, Q7 will read "0" until the erase operation is competed. Upon completion of the erase operation, the data on Q7 will read "1". The Data Polling feature is valid after the rising edge of the sixth WE pulse of six write pulse sequences for automatic chip/sector erase. The Data Polling feature is active during Automatic Program/ Erase algorithm or sector erase time-out.(see section Q3 Sector Erase Timer)
SET-UP AUTOMATIC PROGRAM COMMANDS
To initiate Automatic Program mode, a three-cycle command sequence is required. There are two "unlock" write cycles. These are followed by writing the Automatic Program command A0H. Once the Automatic Program command is initiated, the next WE pulse causes a transition to an active programming operation. Addresses are latched on the falling edge, and data are internally latched on the rising edge of the WE pulse. The rising edge of WE also begins the programming operation. The system does not require to provide further controls or timings. The device will automatically provide an adequate internally generated program pulse and verify margin. If the program operation was unsuccessful, the data on Q5 is "1", indicating the program operation exceed internal timing limit. The automatic programming operation is completed when the data read on Q6 stops toggling for two consecutive read cycles and the data on Q7 and Q6 are equivalent to data written to these two bits, at which time the device returns to the Read mode(no program verify command is required).
Q6:Toggle BIT I
The MX29F002T/B features a "Toggle Bit" as a method to indicate to the host system that the Auto Program/Erase algorithms are either in progress or completed. 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 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(see the subsection on Q7:Data Polling). If a program address falls within a protected sector, Q6 toggles for approximately 2 us 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. The Write Operation Status table shows the outputs for Toggle Bit I on Q6. Refer to the toggle bit algorithm.
REV. 1.5, MAR. 28, 2005
WRITE OPERATION STATUS DATA POLLING-Q7
The MX29F002T/B also features Data Polling as a method to indicate to the host system that the Automatic Program or Erase algorithms are either in progress or completed. While the Automatic Programming algorithm is in operation, an attempt to read the device will produce the complement data of the data last written to Q7. Upon completion of the Automatic Program Algorithm an attempt to read the device will produce the true data last written to Q7. The Data Polling feature is valid after the rising edge of the

MX29F002/002N T/B
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 I is valid after the rising edge of the final WE 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 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.
system must start at the beginning of the algorithm when it returns to determine the status of the operation (top of the toggle bit algorithm flow chart).
Q5 Exceeded Timing Limits
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 which indicates that the program or erase cycle was not successfully completed. Data Polling and Toggle Bit are the 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 maynot be reused, (other sectors are still functional and can be reused). The Q5 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.
Reading Toggle Bits Q6/ Q2
Refer to the toggle bit algorithm for the following discussion. 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

MX29F002/002N T/B
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 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.
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 SUPPLY DECOUPLING
In order to reduce power switching effect, each device should have a 0.1uF ceramic capacitor connected between its VCC and GND.
SECTOR PROTECTION WITH 12V SYSTEM
The MX29F002T/B features hardware sector protection. This feature will disable both program and erase operations for these sectors protected. To activate this mode, the programming equipment must 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 protect algorithm and waveform. 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 in "don't care" state. Address locations with A1 = VIL are reserved to read manufacturer and device codes.(Read Silicon ID) It is also possible to determine if the sector 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.
DATA PROTECTION
The MX29F002T/B is designed to offer protection against accidental erasure or programming caused by spurious system level signals that may exist during power transition. 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.
WRITE PULSE "GLITCH" PROTECTION
Noise pulses of less than 5ns(typical) on CE or WE will not initiate a write cycle.

CHIP UNPROTECT WITH 12V SYSTEM
The MX29F002T/B also features the chip unprotect mode, so that all sectors are unprotected after chip unprotect is completed to incorporate any changes in the code. It is recommended to protect all sectors before activating chip unprotect 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 unprotect algorithm and waveform for the chip unprotect algorithm. The unprotection mechanism begins on the falling edge of the WE pulse and is terminated on the rising edge. 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 is noted that all sectors are unprotected after the chip unprotect algorithm is completed.
