The standard A29L320A offers access times of 70,80,90 and 120ns, allowing high-speed microprocessors to operate without wait states. To eliminate bus contention the device has separate chip enable ( CE ), write enable The A29L320A is a 32Mbit, 3.3 volt-only Flash memory organized as 2,097,152 words of 16 bits or 4,194,304 bytes of 8 bits each. The 8 bits of data appear on I/O0 - I/O7; the 16 bits of data appear on I/O0~I/O15. The A29L320A is offered in 48-ball TFBGA and 48-Pin TSOP packages. This device is designed to be programmed in-system with the standard system 3.3 volt VCC supply. Additional 12.0 volt VPP is not required for in-system write or erase operations. However, the A29L320A can also be programmed in standard EPROM programmers. The A29L320A has the first toggle bit, I/O6, which indicates whether an Embedded Program or Erase is in progress, or it is in the Erase Suspend. Besides the I/O6 toggle bit, the A29L320A has a second toggle bit, I/O2, to indicate whether the addressed sector is being selected for erase. The A29L320A also offers the ability to program in the Erase (November, 2007, Version 1.1) ( WE ) and output enable ( OE ) controls. The device requires only a single 3.3 volt power supply for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations. The A29L320A is entirely software command set compatible with the JEDEC single-power-supply Flash standard. Commands are written to the command register using standard microprocessor write timings. Register 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 1 AMIC Technology, Corp. A29L320A Series contents of other sectors. The A29L320A is fully erased when shipped from the factory. The hardware sector protection feature disables operations for both program and erase in any combination of the sectors of memory. This can be achieved 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 other 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. erase operations. Reading data out of the device is similar to reading from other Flash or EPROM devices. Device programming occurs by writing the proper program command sequence. This initiates the Embedded Program algorithm - an internal algorithm that automatically times the program pulse widths and verifies proper program margin. Device erasure occurs by executing the proper 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 erase margin. The Unlock Bypass mode facilitates faster programming times by requiring only two write cycles to program data instead of four. The host system can detect whether a program or erase operation is complete by observing the RY / BY pin, or by reading the I/O7 ( Data Polling) and I/O6 (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 Pin Configurations TSOP (I) A15 A14 A13 A12 A11 A10 A9 A8 A19 A20 WE RESET NC WP/ACC RY/BY A18 A17 A7 A6 A5 A4 A3 A2 A1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 (November, 2007, Version 1.1) A29L320AV 2 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 A16 BYTE VSS I/O 15(A-1) I/O7 I/O14 I/O6 I/O 13 I/O5 I/O 12 I/O4 VCC I/O 11 I/O3 I/O 10 I/O2 I/O9 I/O1 I/O8 I/O0 OE VSS CE A0 AMIC Technology, Corp.

The contents of the register serve as inputs to the internal state machine. The state machine outputs dictate the function of the device. The appropriate device bus operations table lists the inputs and control levels required, and the resulting output. The following subsections describe each of these operations in further detail. 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 Table 1.

See “Sector/Sector Block Protection and Unprotection”. 3. If WP /ACC=VIL, the two outermost boot sectors remain protected. If WP /ACC=VIH, the two outermost boot sector protection depends on whether they were last protected or unprotected using the method described in “Sector/Sector Block Protection and Unprotection. If WP /ACC = VHH, all sectors are unprotected. 4. DIN or DOUT as required by command sequence, data polling, or sector protection algorithm. (November, 2007, Version 1.1) 5 AMIC Technology, Corp. A29L320A Series Characteristics" section contains timing specification tables and timing diagrams for write operations. Word/Byte Configuration The BYTE pin determines whether the I/O pins I/O15-I/O0 operate in the byte or word configuration. If the BYTE pin is set at logic ”1”, the device is in word configuration, I/O15-I/O0 are active and controlled by CE and OE . 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 I/O7 - I/O0. Standard read cycle timings and ICC read specifications apply. Refer to "Write Operation Status" for more information, and to each AC Characteristics section for timing diagrams. If the BYTE pin is set at logic “0”, the device is in byte configuration, and only I/O0-I/O7 are active and controlled by CE and OE . I/O8-I/O14 are tri-stated, and I/O15 pin is used as an input for the LSB(A-1) address function. Standby Mode Requirements for Reading Array Data 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. 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 all the time during read operation. The BYTE pin determines whether the device outputs array data in words and 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 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" for more information. Refer to the AC Read Operations table for timing specifications and to the Read Operations Timings diagram for the timing waveforms, lCC1 in the DC Characteristics table represents the active current specification for reading array data. The device enters the CMOS standby mode when the CE & RESET pins are both held at VCC ± 0.3V. (Note that this is a more restricted voltage range than VIH.) If CE and RESET are held at VIH, but not within VCC ± 0.3V, the device will be in the standby mode, but the standby current will be greater. The device requires the standard access time (tCE) 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 in the DC Characteristics tables represent the standby current specification. Automatic Sleep Mode The automatic sleep mode minimizes Flash device energy consumption. The device automatically enables this mode when addresses 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. 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, Refer to “Word/Byte Configuration” 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. The “ Word / Byte Program Command Sequence” section has details on programming data to the device using both standard and Unlock Bypass command sequence. An erase operation can erase one sector, multiple sectors, or the entire device. The Sector Address Tables indicate the address range that each sector occupies. A "sector address" consists of the address inputs required to uniquely select a sector. See the "Command Definitions" section for 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 I/O7 - I/O0. Standard read cycle timings apply in this mode. Refer to the "Autoselect Mode" and "Autoselect Command Sequence" sections for more information. ICC2 in the DC Characteristics table represents the active current specification for the write mode. The "AC (November, 2007, Version 1.1) Output Disable Mode When the OE input is at VIH, output from the device is disabled. The output pins are placed in the high impedance state. 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 low 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. 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 ± 0.3V, the standby current will be greater. 6 AMIC Technology, Corp. A29L320A Series 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 return to VIH. Refer to the AC Characteristics tables for RESET parameters and diagram. 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 tREADY (during Embedded Algorithms). The system can thus monitor Table 2.

When all necessary bits have been set as required, the programming equipment may then read the corresponding identifier code on I/O7 - I/O0.To access the autoselect codes in-system, the host system can issue the autoselect command via the command register, as shown in the Command Definitions table. This method does not require VID. See "Command Definitions" for details on using the autoselect mode. Autoselect Mode The autoselect mode provides manufacturer and device identification, and sector protection verification, through identifier codes output on I/O7 - I/O0. 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 (8.5V to 10.5V) on address pin A9.

A29L320A Series Sector Protection/Unprotection Write Pulse "Glitch" Protection 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. It is possible to determine whether a sector is protected or unprotected. See “Autoselect Mode” 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 2 shows the algorithm and the Sector Protect / Unprotect Timing Diagram illustrates the timing waveforms for this feature. 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 for protection and unprotection is by software sector block protect/unprotect command. See Figure 2 for Command Flow. The device is shipped with all sectors unprotected. It is possible to determine whether a sector is protected or unprotected. See "Autoselect Mode" for details. Noise pulses of less than 5ns (typical) on OE , CE or WE do not initiate a write cycle. 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. 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 the initial power-up. Temporary Sector Unprotect This feature allows temporary unprotection of previous protected sectors to change data in-system. 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 1 shows the algorithm, and the Temporary Sector Unprotect diagram shows the timing waveforms, for this feature. Hardware Data Protection The requirement of command unlocking sequence for programming or erasing provides data protection against inadvertent writes (refer to the Command Definitions table). 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 transitions, or from system noise. The device is powered up to read array data to avoid accidentally writing data to the array. (November, 2007, Version 1.1) 13 AMIC Technology, Corp.

The system can read CFI information at the addresses given in Table 5-8. 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 5-8. The system must write the reset command to return the device to the autoselect mode. 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 interface for long-term compatibility.

A29L320A Series Command Definitions Autoselect Command Sequence Writing specific address and data commands or sequences into the command register initiates device operations. The Command Definitions table 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 the "AC Characteristics" section. The autoselect command sequence allows the host system to access the manufacturer and devices codes, and determine whether or not a sector is protected. The Command Definitions table shows the address and data requirements. This method is an alternative to that shown in the Autoselect Codes (High Voltage Method) table, 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 and another read cycle at XX11h retrieves the continuation code. A read cycle at address XX01h returns the device code. A read cycle containing a sector address (SA) and the address 02h in returns 01h if that sector is protected, or 00h if it is unprotected. Refer to the Sector Address tables for valid sector addresses. The system must write the reset command to exit the autoselect mode and return to reading array data. 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 erase-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" for more information on this mode. The system must issue the reset command to re-enable the device for reading array data if I/O5 goes high, or while in the autoselect mode. See the "Reset Command" section, next. See also "Requirements for Reading Array Data" in the "Device Bus Operations" section for more information. The Read Operations table provides the read parameters, and Read Operation Timings diagram shows the timing diagram. 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. The device automatically provides internally generated program pulses and verify the programmed cell margin. Table 9 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 longer latched. The system can determine the status of the program operation by using I/O7, I/O6, or RY/ BY . See “White 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 I/O5 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”. 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 I/O5 goes high during a program or erase operation, writing the reset command returns the device to reading array data (also applies during Erase Suspend). (November, 2007, Version 1.1) 20 AMIC Technology, Corp. A29L320A Series 00h. Addresses are don’t care for both cycle. The device returns to reading array data. Figure 3 illustrates the algorithm for the program operation. See the Erase/Program Operations in “AC Characteristics” for parameters, and to Program Operation Timings for timing diagrams. START Write Program Command Sequence 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. The Command Definitions table 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. The system can determine the status of the erase operation by using I/O7, I/O6, or I/O2. See "Write Operation Status" 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 4 illustrates the algorithm for the erase operation. See the Erase/Program Operations tables in "AC Characteristics" for parameters, and to the Chip/Sector Erase Operation Timings for timing waveforms. Data Poll from System Embedded Program algorithm in progress Verify Data ? No Yes Increment Address No Last Address ? Yes Programming Completed 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. The Command Definitions table 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 timeout of 50μs 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 50μs, 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 50μs, the system need not monitor I/O3. 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. Note : See the appropriate Command Definitions table for program command sequence. Figure 3. Program Operation 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 9 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 twocycle unlock bypass reset command sequence. The first cycle must contain the data 90h; the second cycle the data (November, 2007, Version 1.1) 21 AMIC Technology, Corp. A29L320A Series The system can monitor I/O3 to determine if the sector erase timer has timed out. (See the " I/O3: Sector Erase Timer" section.) 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. 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 I/O7, I/O6, or I/O2. Refer to "Write Operation Status" for information on these status bits. 4 illustrates the algorithm for the erase operation. Refer to the Erase/Program Operations tables in the "AC Characteristics" section for parameters, and to the Sector Erase Operations Timing diagram for timing waveforms. 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. START Write Erase Command Sequence 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 50μs 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 20μs 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 I/O7 - I/O0. The system can use I/O7, or I/O6 and I/O2 together, to determine if a sector is actively erasing or is erasesuspended. See "Write Operation Status" for information on these status bits. After an erase-suspended program operation is complete, the system can once again read array data within nonsuspended sectors. The system can determine the status of the program operation using the I/O7 or I/O6 status bits, just as in the standard program operation. See "Write Operation Status" for more 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" for more information.

See "Autoselect Command Sequence" for more information. 9. Once a reset command is applied, software temporary unprotect is exit to return to read array data. But under erase suspend condition, this command is still effective even a reset command has been applied. The reset command which can deactivate the software temporary unprotect command is useful only after the erase command is complete. 10.

(November, 2007, Version 1.1) 24 AMIC Technology, Corp. A29L320A Series Write Operation Status Several bits, I/O2, I/O3, I/O5, I/O6, I/O7, RY/ BY are provided in the A29L320A to determine the status of a write operation. Table 10 and the following subsections describe the functions of these status bits. I/O7, I/O6 and RY/ BY each offer a method for determining whether a program or erase operation is complete or in progress. These three bits are discussed first. START Read I/O7-I/O0 Address = VA I/O7: Data Polling The Data Polling bit, I/O7, 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 Yes I/O7 = Data ? 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 I/O7 the complement of the datum programmed to I/O7. This I/O7 status also applies to programming during Erase Suspend. When the Embedded Program algorithm is complete, the device outputs the datum programmed to I/O7. The system must provide the program address to read valid status information on I/O7. If a program address falls within a protected sector, Data Polling on I/O7 is active for approximately 2μs, then the device returns to reading array data. During the Embedded Erase algorithm, Data Polling produces a "0" on I/O7. When the Embedded Erase algorithm is complete, or if the device enters the Erase Suspend mode, Data Polling produces a "1" on I/O7.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 I/O7. After an erase command sequence is written, if all sectors selected for erasing are protected, Data Polling on I/O7 is active for approximately 100μs, 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 I/O7 has changed from the complement to true data, it can read valid data at I/O7 - I/O0 on the following read cycles. This is because I/O7 may change asynchronously with I/O0 - I/O6 while Output Enable ( OE ) is asserted low. The Data Polling Timings (During Embedded Algorithms) figure in the "AC Characteristics" section illustrates this. Table 10 shows the outputs for Data No No I/O5 = 1? Yes Read I/O7 - I/O0 Address = VA Yes I/O7 = Data ? No FAIL Note : 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. I/O7 should be rechecked even if I/O5 = "1" because I/O7 may change simultaneously with I/O5. Polling on I/O7. Figure 5 shows the Data Polling algorithm. (November, 2007, Version 1.1) PASS Figure 5. Data Polling Algorithm 25 AMIC Technology, Corp. A29L320A Series RY/ BY : Read/ Busy I/O2: Toggle Bit II 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 10 shows the outputs for RY/ BY . Refer to “ RESET Timings”, “Timing Waveforms for Program Operation” and “Timing Waveforms for Chip/Sector Erase Operation” for more information. I/O6: Toggle Bit I Toggle Bit I on I/O6 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 I/O6 to toggle. (The system may use either OE or CE to control the read cycles.) When the operation is complete, I/O6 stops toggling. After an erase command sequence is written, if all sectors selected for erasing are protected, I/O6 toggles for approximately 100μs, 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 I/O6 and I/O2 together to determine whether a sector is actively erasing or is erase-suspended. When the device is actively erasing (that is, the Embedded Erase algorithm is in progress), I/O6 toggles. When the device enters the Erase Suspend mode, I/O6 stops toggling. However, the system must also use I/O2 to determine which sectors are erasing or erase-suspended. Alternatively, the system can use I/O7 (see the subsection on " I/O7 : Data Polling"). If a program address falls within a protected sector, I/O6 toggles for approximately 2μs after the program command sequence is written, then returns to reading array data. I/O6 also toggles during the erase-suspend-program mode, and stops toggling once the Embedded Program algorithm is complete. The Write Operation Status table shows the outputs for Toggle Bit I on I/O6. Refer to Figure 6 for the toggle bit algorithm, and to the Toggle Bit Timings figure in the "AC Characteristics" section for the timing diagram. The I/O2 vs. I/O6 figure shows the differences between I/O2 and I/O6 in graphical form. See also the subsection on " I/O2: Toggle Bit II". (November, 2007, Version 1.1) 26 The "Toggle Bit II" on I/O2, when used with I/O6, 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. I/O2 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 I/O2 cannot distinguish whether the sector is actively erasing or is erase-suspended. I/O6, 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 10 to compare outputs for I/O2 and I/O6. Figure 6 shows the toggle bit algorithm in flowchart form, and the section " I/O2: Toggle Bit II" explains the algorithm. See also the " I/O6: Toggle Bit I" subsection. Refer to the Toggle Bit Timings figure for the toggle bit timing diagram. The I/O2 vs. I/O6 figure shows the differences between I/O2 and I/O6 in graphical form. Reading Toggle Bits I/O6, I/O2 Refer to Figure 6 for the following discussion. Whenever the system initially begins reading toggle bit status, it must read I/O7 - I/O0 at least twice in a row to determine whether a toggle bit is toggling. Typically, a 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 I/O7 - I/O0 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 I/O5 is high (see the section on I/O5). 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 I/O5 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 I/O5 has not gone high. The system may continue to monitor the toggle bit and I/O5 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 (top of Figure 6). I/O5: Exceeded Timing Limits I/O5 indicates whether the program or erase time has exceeded a specified internal pulse count limit. Under these conditions I/O5 produces a "1." This is a failure condition that indicates the program or erase cycle was not successfully completed. AMIC Technology, Corp. A29L320A Series The I/O5 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, I/O5 produces a "1." Under both these conditions, the system must issue the reset command to return the device to reading array data. START Read I/O7-I/O0 I/O3: Sector Erase Timer After writing a sector erase command sequence, the system may read I/O3 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. When the time-out is complete, I/O3 switches from "0" to "1." The system may ignore I/O3 if the system can guarantee that the time between additional sector erase commands will always be less than 50μs. See also the "Sector Erase Command Sequence" section. After the sector erase command sequence is written, the system should read the status on I/O7 ( Data Polling) or I/O6 (Toggle Bit 1) to ensure the device has accepted the command sequence, and then read I/O3. If I/O3 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 I/O3 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 I/O3 prior to and following each subsequent sector erase command. If I/O3 is high on the second status check, the last command might not have been accepted. Table 10 shows the outputs for I/O3. Read I/O7-I/O0 Toggle Bit = Toggle ? (Note 1) No Yes No I/O5 = 1? Yes Read I/O7 - I/O0 Twice Toggle Bit = Toggle ? (Notes 1,2) No Yes Program/Erase Operation Not Commplete, Write Reset Command Program/Erase Operation Complete 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 I/O5 changes to "1". See text. Figure 6.

The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes program faster than the maximum byte program time listed. If the maximum byte program time given is exceeded, only then does the device set I/O5 = 1. See the section on I/O5 for further information. 3. In the pre-programming step of the Embedded Erase algorithm, all bytes are programmed to 00h before erasure. 4. System-level overhead is the time required to execute the four-bus-cycle command sequence for programming. See Table 9 for further information on command definitions. 5. The device has a guaranteed minimum erase and program cycle endurance of 100,000 cycles. (November, 2007, Version 1.1) 41 AMIC Technology, Corp.
