Word mode data appears on I/O0–I/O15; byte mode data appears on I/O0– I/O7. The device is designed to be programmed in-system with the standard 3.0 volt VCC supply, and can also be programmed in standard EPROM programmers. The device is available with an access time of 70ns. The devices are offered in 69-ball Fine-pitch BGA. Standard control pins—chip enable ( CE_F ), write enable ( WE ), and output enable ( OE )—control normal read and write operations, and avoid bus contention issues. The device requires only a single 3.0 volt power supply for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations. A82DL32x4T(U) Features The device offers complete compatibility with the JEDEC single-power-supply Flash command set standard. Commands are written to the command register using standard microprocessor write timings. Reading data out of the device is similar to reading from other Flash or EPROM devices. The host system can detect whether a program or erase operation is complete by using the device status bits: RY/ BY pin, I/O7 ( Data Polling) and I/O6/I/O2 (toggle bits). After a program or erase cycle has been completed, the device automatically returns to reading array data. The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the data contents of other sectors. The device is fully erased when shipped from the factory. Hardware data protection measures include a low VCC detector that automatically inhibits write operations during power transitions. The hardware sector protection feature disables both program and erase operations in any combination of the sectors of memory. This can be achieved in-s y s t e m or via programming equipment. 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 modes. Simultaneous Read/Write Operations with Zero Latency The Simultaneous Read/Write architecture provides simultaneous operation by dividing the memory space into two banks. The device can improve overall system performance by allowing a host system to program or erase in one bank, then immediately and simultaneously read from the other bank, with zero latency. This releases the system from waiting for the completion of program or erase operations. The A82DL32x4T(U) devices uses multiple bank architectures to provide flexibility for different applications.

The command register itself does not occupy any addressable memory location. The register is composed of latches that store the commands, along with the address and data information needed to execute the command. The contents of the register serve as inputs to the internal state machine. The state machine outputs dictate the function of the device. 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.

If the BYTE_F pin is set at logic ”1”, the device is in word configuration, I/O15I/O0 are active and controlled by CE_F and OE . If the BYTE_F pin is set at logic “0”, the device is in byte configuration, and only I/O0-I/O7 are active and controlled by CE_F 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. Characteristics" section contains timing specification tables and timing diagrams for write operations. Accelerated Program Operation The device offers accelerated program operations through the ACC function. This is one of two functions provided by the WP /ACC pin. This function is primarily intended to allow faster manufacturing throughput at the factory. If the system asserts VHH on this pin, the device automatically enters the aforementioned Unlock Bypass mode, temporarily unprotects any protected sectors, and uses the higher voltage on the pin to reduce the time required for program operations. The system would use a two-cycle program command sequence as required by the Unlock Bypass mode. Removing VHH from the WP /ACC pin returns the device to normal operation. Note that the WP /ACC pin must not be at VHH for operations other than accelerated programming, or device damage may result. In addition, the WP /ACC pin must not be left floating or unconnected; inconsistent behavior of the device may result. Autoselect Functions If 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. Requirements for Reading Array Data To read array data from the outputs, the system must drive the CE_F and OE pins to VIL. CE_F is the power control and selects the device. OE is the output control and gates array data to the output pins. WE should remain at VIH. The BYTE_F pin determines whether the device outputs array data in words or bytes. The internal state machine is set for reading array data upon device power-up, or after a hardware reset. This ensures that no spurious alteration of the memory content occurs during the power transition. No command is necessary in this mode to obtain array data. Standard microprocessor read cycles that assert valid addresses on the device address inputs produce valid data on the device data outputs. Each bank remains enabled for read access until the command register contents are altered. See "Requirements for Reading Array Data" for more information. Refer to the AC Read-Only Operations table for timing specifications and to Figure 11 for the timing waveform, lCC1_F in the DC Characteristics table represents the active current specification for reading array data. Simultaneous Read/Write Operations with Zero Latency This device is capable of reading data from one bank of memory while programming or erasing in the other bank of memory. An erase operation may also be suspended to read from or program to another location within the same bank (except the sector being erased). Figure 18 shows how read and write cycles may be initiated for simultaneous operation with zero latency. ICC6_F and ICC7_F in the DC Characteristics table represent the current specifications for read-while-program and read-while-erase, respectively. Standby Mode When the system is not reading or writing to the device, it can place the device in the standby mode. In this mode, current consumption is greatly reduced, and the outputs are placed in the high impedance state, independent of the OE input. The device enters the CMOS standby mode when the CE_F & RESET pins are both held at VCC_F ± 0.3V. (Note that this is a more restricted voltage range than VIH.) If CE_F and RESET are held at VIH, but not within VCC_F ± 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) for read access when the device is in either of these standby modes, before it is ready to read data. If the device is deselected during erasure or programming, the device draws active current until the operation is completed. ICC3_F in the DC Characteristics tables represent the standby 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_F to VIL, and OE to VIH. For program operations, the BYTE_F 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 a bank 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 3-4 indicate the address range that each sector occupies. The device address space is divided into two banks: Bank 1 contains the boot/parameter sectors, and Bank 2 contains the larger, code sectors of uniform size. A “bank address” is the address bits required to uniquely select a bank. Similarly, a “sector address” is the address bits required to uniquely select a sector. ICC2_F in the DC Characteristics table represents the active current specification for the write mode. The "AC PRELIMINARY (August, 2005, Version 0.0) 10 AMIC Technology, Corp. A82DL32x4T(U) Series 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_F , 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_F in the DC Characteristics table represents the automatic sleep mode current specification. 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 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. 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_F ). If RESET is held at VIL but not within VSS ± 0.3V, the standby current will be greater.

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 12.5 V) on address pin A9. Address pins A6, A1, and A0 must be as shown in Table 5. In addition, when verifying sector protection, the sector address must appear on the appropriate highest order address bits. (see Table 3-4). Table 5 shows the remaining address bits that are don't care. When all necessary bits have been set as required, the programming equipment may then read the corresponding identifier code on 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 Table 12. This method does not require VID. Refer to the Autoselect Command Sequence section for more information. Table 5.

The hardware sector unprotection feature re-enables both program and erase operations in previously protected sectors. Sector protection and 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 algorithms and Figure 23 shows the timing diagram. This method uses standard microprocessor bus cycle timing. For sector unprotect, all unprotected sectors must first be protected prior to the first sector unprotect write cycle. The sector unprotect algorithm unprotects all sectors in parallel. All previously protected sectors must be individually re-protected. To change data in protected sectors efficiently, the temporary sector unprotect function is available. See “Temporary Sector/Sector Block Unprotect”. The alternate method for protection and unprotection is by software temporary sector /sector block 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 the Autoselect Mode section for details. Write Protect ( WP /ACC) The Write Protect function provides a hardware method of protecting certain boot sectors without using VID. This function is one of two provided by the WP /ACC pin. If the system asserts VIL on the WP /ACC pin, the device disables program and erase functions in the two “outermost” 8 Kbyte boot sectors independently of whether those sectors were protected or unprotected using the method described in “Sector/Sector Block Protection and Unprotection”. The two outermost 8 Kbyte boot sectors are the two sectors containing the lowest addresses in a bottom-boot-configured device, or the two sectors containing the highest addresses in a top-boot-configured device. If the system asserts VIH on the WP /ACC pin, the device reverts to whether the two outermost 8 Kbyte boot sectors were last set to be protected or unprotected. That is, sector protection or unprotection for these two sectors depends on whether they were last protected or unprotected using the method described in “Sector/Sector Block Protection and Unprotection”. Note that the WP /ACC pin must not be left floating or unconnected; inconsistent behavior of the device may result. Temporary Sector/Sector Block Unprotect (Note: For the following discussion, the term “sector” applies to both sectors and sector blocks. A sector block consists of two or more adjacent sectors that are protected or unprotected at the same time (see Tables 6 and 7). This feature allows temporary unprotection of previously protected sectors to change data in-system. The Sector Unprotect mode is activated by setting the RESET pin to VID (8.5V-12.5V). 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 Figure 22 shows the timing diagrams, for this feature.

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_F power-up and power-down transitions, or from system noise. Low VCC Write Inhibit When VCC_F is less than VLKO, the device does not accept any write cycles. This protects data during VCC_F power-up and power-down. The command register and all internal program/erase circuits are disabled, and the device resets to reading array data. Subsequent writes are ignored until VCC_F is greater than VLKO. The system must provide the proper signals to the control pins to prevent unintentional writes when VCC_F is greater than VLKO. Write Pulse “Glitch” Protection Noise pulses of less than 5ns (typical) on OE , CE_F or Power-Up Write Inhibit If WE = CE_F = VIL and OE = VIH during power up, the device does not accept commands on the rising edge of WE . The internal state machine is automatically reset to reading array data on power-up. COMMON FLASH MEMORY INTERFACE (CFI) The Common Flash Interface (CFI) specification outlines device and host system software interrogation handshake, which allows specific vendor-specified software algorithms to be used for entire families of devices. Software support can then be device-independent, JEDEC ID-independent, and forward- and backward-compatible for the specified flash device families. Flash vendors can standardize their existing interfaces for long-term compatibility. This device enters the CFI Query mode when the system writes the CFI Query command, 98h, to address 55h in word mode (or address AAh in byte mode), any time the device is ready to read array data. The system can read CFI information at the addresses given in Tables 8-11. 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 Tables 8-11. The system must write the reset command to return the device to the autoselect mode. WE do not initiate a write cycle. Logical Inhibit Write cycles are inhibited by holding any one of OE = VIL, CE_F = VIH or WE = VIH. To initiate a write cycle, CE_F and WE must be a logical zero while OE is a logical one. Table 8.

Table 12 defines the valid register command sequences. Writing incorrect address and data values or writing them in the improper sequence may place the device in an unknown state. A reset command is then required to return the device to reading array data. All addresses are latched on the falling edge of WE or CE_F , whichever happens later. All data is latched on the rising edge of WE or CE_F , whichever happens first. Refer to the AC Characteristics section for timing diagrams. (or erase-suspend-read mode if that bank was in Erase Suspend). Autoselect Command Sequence The autoselect command sequence allows the host system to access the manufacturer and device codes, and determine whether or not a sector is protected. Table 12 shows the address and data requirements. This method is an alternative to that shown in Table 5, which is intended for PROM programmers and requires VID on address pin A9. The autoselect command sequence may be written to an address wit h in a bank that is either in t he read or erasesuspend-read mode. The autoselect command may not be written while the device is actively programming or erasing in the other bank. The autoselect command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle that contains the bank address and the autoselect command. T he bank then enter s the autoselect mode. The system may read at any address within the same bank any number of times without initiating another autoselect command sequence: A read cycle at address (BA)XX00h (where BA is the bank address) returns the manufacturer code. A read cycle at address (BA)XX01h in word mode (or (BA)XX02h in byte mode) returns the device code. A read cycle to an address containing a sector address (SA) within the same bank, and the address 02h on A7-A0 in word mode (or the address 04h on A6-A-1 in byte mode) returns 01h if the sector is protected, or 00h if it is unprotected. (Refer to Tables 3-4 for valid sector addresses). The system must write the reset command to return to reading array data (or erase-suspend-read mode if the bank was previously in Erase Suspend). 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 corresponding bank enters the erase-suspend-read mode, after which the system can read data from any non-erasesuspended sector within the same bank. After completing a programming operation in the Erase Suspend mode, the system may once again read array data with the same exception. See the Erase Suspend/Erase Resume Commands section for more information. The system must issue the reset command to return a bank to the read (or erase-suspend-read) mode if I/O5 goes high during an active program or erase operation, or if the bank is in the autoselect mode. See the next section, Reset Command, for more information. See also Requirements for Reading Array Data in the Device Bus Operations section for more information. The Read-Only Operations table provides the read parameters, and Figure 11 shows the timing diagram. Byte/Word Program Command Sequence The system may program the device by word or byte, depending on the state of the BYTE_F 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 verifies the programmed cell margin. Table 12 shows the address and data requirements for the byte program command sequence. When the Embedded Program algorithm is complete, that bank then returns to reading array data and addresses are no longer latched. The system can determine the status of the program operation by using I/O7, I/O6, or RY/ BY . Refer to the Write Operation Status section 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 program operation. The program command sequence should be reinitiated once that bank has returned to reading array data, to ensure data integrity. Programming is allowed in any sequence and across sector boundaries. A bit cannot be programmed from “0” back to a “1.” Attempting to do so may cause that bank to set I/O5 = 1, or cause the I/O7 and I/O6 status bits 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.” 25 Reset Command Writing the reset command resets the banks to the read or erase-suspend-read mode. Address bits are don’t cares for this command. The reset command may be written between the sequence cycles in an erase command sequence before erasing begins. This resets the bank to which the system was writing 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 bank to which the system was writing to reading array data. If the program command sequence is written to a bank that is in the Erase Suspend mode, writing the reset command returns that bank to the erase-suspend-read 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. If a bank entered the autoselect mode while in the Erase Suspend mode, writing the reset command returns that bank to the erase-suspend-read mode. If I/O5 goes high during a program or erase operation, writing the reset command returns the banks to reading array data PRELIMINARY (August, 2005, Version 0.0) AMIC Technology, Corp. A82DL32x4T(U) Series Unlock Bypass Command Sequence The unlock bypass feature allows the system to program bytes or words to a bank 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 12 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 device then returns to reading array data. The device offers accelerated program operations through the WP /ACC pin. When the system asserts VHH on the WP /ACC pin, the device automatically enters the Unlock Bypass mode. The system may then write the two-cycle Unlock Bypass program command sequence. The device uses the higher voltage on the WP /ACC pin to accelerate the operation. Note that the WP /ACC pin must not be at VHH any operation other than accelerated programming, or device damage may result. In addition, the WP /ACC pin must not be left floating or unconnected; inconsistent behavior of the device may result. Figure 3 illustrates the algorithm for the program operation. Refer to the Erase and Program Operations table in the AC Characteristics section for parameters, and Figure 15 for timing diagrams.

The chip erase command sequence is initiated by writing two unlock cycles, followed by a set-up command. Two additional unlock write cycles are then followed by the chip erase command, which in turn invokes the Embedded Erase algorithm. The device does not require the system to preprogram prior to erase. The Embedded Erase algorithm automatically preprograms and verifies the entire memory for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or timings during these operations. Table 12 shows the address and data requirements for the chip erase command sequence. When the Embedded Erase algorithm is complete, that bank 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, I/O2, or RY/ BY . Refer to the Write Operation Status section for information on these status bits. Any commands written during the chip erase operation are ignored. However, note that a hardware reset immediately terminates the erase operation. If that occurs, the chip erase command sequence should be reinitiated once that bank has returned to reading array data, to ensure data integrity. Figure 4 illustrates the algorithm for the erase operation. Refer to the Erase and Program Operations tables in the AC Characteristics section for parameters, and Figure 17 section for timing diagrams. When the Embedded Erase algorithm is complete, the bank returns to reading array data and addresses are no longer latched. Note that while the Embedded Erase operation is in progress, the system can read data from the non-erasing bank. The system can determine the status of the erase operation by reading I/O7, I/O6, I/O2, or RY/ BY in the erasing bank. Refer to the Write Operation Status section for information on these status bits. Once the sector erase operation has begun, only the Erase Suspend command is valid. All other commands are ignored. However, note that a hardware reset immediately terminates the erase operation. If that occurs, the sector erase command sequence should be reinitiated once that bank has returned to reading array data, to ensure data integrity. Figure 4 illustrates the algorithm for the erase operation. Refer to the Erase and Program Operations tables in the AC Characteristics section for parameters, and Figure 17 section for timing diagrams Erase Suspend/Erase Resume Commands The Erase Suspend command, B0h, allows the system to interrupt a sector erase operation and then read data from, or program data to, any sector not selected for erasure. This command is valid only during the sector erase operation, including the 50 µs 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. When the Erase Suspend command is written during the sector erase operation, the device requires a maximum of 20 µs to suspend the erase operation. However, when the Erase Suspend command is written during the sector erase timeout, the device immediately terminates the time-out period and suspends the erase operation. After the erase operation has been suspended, the bank enters the erase-suspend-read mode. The system can read data from or program data to any sector not selected for erasure. (The device “erase suspends” all sectors selected for erasure.) Reading at any address within erase-suspended sectors produces status information 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 erase-suspended. Refer to the Write Operation Status section for information on these status bits. After an erase-suspended program operation is complete, the bank returns to the erase-suspend-read mode. The system can determine the status of the program operation using the I/O7 or I/O6 status bits, just as in the standard Byte Program operation. Refer to the Write Operation Status section for more information. In the erase-suspend-read mode, the system can also issue the autoselect command sequence. Refer to the Autoselect Mode and Autoselect Command Sequence sections for details. To resume the sector erase operation, the system must write the Erase Resume command. The bank address of the erase-suspended bank is ignored when writing this command. Further writes of the Resume command are ignored. Another Erase Suspend command can be written after the chip has resumed erasing. 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 cycles are written, and are then followed by the address of the sector to be erased, and the sector erase command. Table 12 shows the address and data requirements for the sector erase command sequence. The device does not require the system to preprogram prior to erase. The Embedded Erase algorithm automatically programs 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. After the command sequence is written, a sector erase timeout of 50 µs occurs. During the time-out period, additional sector addresses and sector erase commands within the bank 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 erasure may begin. Any sector erase address and command following the exceeded time-out may or may not be accepted. 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. Any command other than Sector Erase or Erase Suspend during the time-out period resets that bank to reading array data. The system must rewrite the command sequence and any additional addresses and commands. The system can monitor I/O3 to determine if the sector erase timer has timed out (See the section on I/O3: Sector Erase Timer.). The time-out begins from the rising edge of the final WE pulse in the command sequence.

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. PRELIMINARY (August, 2005, Version 0.0) 29 AMIC Technology, Corp. A82DL32x4T(U) Series WRITE OPERATION STATUS The device provides several bits to determine the status of a program or erase operation: I/O2, I/O3, I/O5, I/O6, and I/O7. Table 13 and the following subsections describe the function of these bits. I/O7 and I/O6 each offer a method for determining whether a program or erase operation is complete or in progress. The device also provides a hardware-based output signal, RY/ BY , to determine whether an Embedded Program or Erase operation is in progress or has been completed. 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 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 1µs, 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. 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 bank 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. However, if the system reads I/O7 at an address within a protected sector, the status may not be valid. Just prior to the completion of an Embedded Program or Erase operation, I/O7 may change asynchronously with I/O0– I/O6 while Output Enable ( OE ) is asserted low. That is, the device may change from providing status information to valid data on I/O7. Depending on when the system samples the I/O7 output, it may read the status or valid data. Even if the device has completed the program or erase operation and I/O7 has valid data, the data outputs on I/O0-I/O6 may be still invalid. Valid data on I/O0-I/O7 will appear on successive read cycles. Table 13 shows the outputs for Data Polling on I/O7. Figure 5 shows the Data Polling algorithm. Figure 19 in the AC Characteristics section shows the Data Polling timing diagram. I/O7 = Data ? Yes No No I/O5 = 1? Yes Read I/O7 - I/O0 Address = VA Yes I/O7 = Data ? No FAIL PASS 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/O . 5 Figure 5. Data Polling Algorithm PRELIMINARY (August, 2005, Version 0.0) 30 AMIC Technology, Corp. A82DL32x4T(U) Series RY/ BY : Ready/ Busy The RY/ BY is a dedicated, open-drain output pin that indicates whether an Embedded algorithm is in progress or complete. The RY/ BY status is valid after the rising edge of the final WE pulse in the command sequence. Since RY/ BY is an open-drain output, several RY/ BY pins can be tied together in parallel with a pull-up resistor to VCC_F. 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 13 shows the outputs for RY/ BY . START Read I/O7-I/O0 Read I/O7-I/O0 (Note 1) 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_F 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 1µs 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. Table 13 shows the outputs for Toggle Bit I on I/O6. Figure 6 shows the toggle bit algorithm. Figure 20 in the “AC Characteristics” section shows the toggle bit timing diagrams. Figure 23 shows the differences between I/O2 and I/O6 in graphical form. See also the subsection on I/O2: Toggle Bit II. Toggle Bit = Toggle ? Yes No No I/O5 = 1? Yes Read I/O7 - I/O0 Twice (Notes 1,2) Toggle Bit = Toggle ? No Yes Program/Erase Operation Not Commplete, Write Reset Command Program/Erase Operation Complete Note: The system should recheck the toggle bit even if I/O5=”1" because the toggle bit may stop toggling as I/O5 changes to “1”. See the subsections on I/O6 and I/O2 for more information. Figure 6. Toggle Bit Algorithm PRELIMINARY (August, 2005, Version 0.0) 31 AMIC Technology, Corp. A82DL32x4T(U) Series I/O2: Toggle Bit II 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_F 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 8 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. Figure 20 shows the toggle bit timing diagram. Figure 21 shows the differences between I/O2 and I/O6 in graphical form. 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. The device may output a “1” on I/O5 if the system tries to program a “1” to a location that was 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 timing limit has been exceeded, I/O5 produces a “1.” . Under both these conditions, the system must write the reset command to return to reading array data (or to the erasesuspend-read mode if a bank was previously in the erasesuspend-program mode). 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 (Except 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 13 shows the status of I/O3 relative to the other status bits. 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).

Typical program and erase times assume the following conditions: 25°C, 3.0V VCC_F, 10,000 cycles. Additionally, programming typically assumes checkerboard pattern. 2. Under worst case conditions of 90°C, VCC_F = 2.7V, 100,000 cycles. 3. 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. 4. In the pre-programming step of the Embedded Erase algorithm, all bytes are programmed to 00h before erasure. 5. System-level overhead is the time required to execute the four-bus-cycle command sequence for programming. See Table 12 for further information on command definitions. 6.
