Bottom boot configuration is shown in the following table. Bank Bank 1 Bank 2 Bank 3 Bank 4 Megabits 4 Mb 12 Mb 12 Mb 4 Mb Sector Sizes Eight 32 Kword Twenty-four 32 Kword Twenty-four 32 Kword Eight 4 Kword, Seven 32 Kword Am29DL640H and Am29DL320G Features Am29DL640H is a 64 megabit, 3.0 volt-only flash memory device, organized as 4,194,304 words. The Am29DL320G is a 32 megabit, 3.0 volt-only flash memory device, organized as 2,097,152 words. Word mode data appears on DQ15–DQ0. 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 70 or 85 ns and is offered in a 73-ball FBGA package. Standard control pins—chip enable (CE#fx), 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. Available on Am29DL640H and Am29DL320G, the SecSi™ (Secured Silicon) Sector is an extra 256 byte sector capable of being permanently locked by AMD or customers. The Secure SectorSecSi Indicator Bit (DQ7) is permanently set to a 1 if the part is factory locked, and set to a 0 if customer lockable. This way, customer lockable parts can never be used to replace a factory locked part. Factory locked parts provide several options. The Secure SectorSecSi Sector may store a secure, random 16 byte ESN (Electronic Serial Number), customer code (programmed through AMD’s ExpressFlash service), or both. Customer Lockable parts may utilize the Secure SectorSecSi Sector as a one-time programmable area. The AMD DMS (Data Management Software) manages data programming, enables EEPROM emulation, and eases historical sector erase flash limitations. For more information on DMS or to obtain the software, contact AMD or an authorized representative. 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, DQ7 (Data# Polling) and DQ6/DQ2 (toggle bits). After a program or erase cycle has been completed, the device automatically returns to the read mode. 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 m easures include a low V CC d etector that automatically inhibits write operations during power transitions. The hardware sector protection feature disables both program and erase operations in any combination of the sectors of memory. This can be achieved in-system or via programming equipment. The 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 b y dividing the memory space into four banks. Sector addresses are fixed, system software can be used to form user-defined bank groups. During an Erase/Program operation, any of the three non-busy banks may be read from. Note that only two banks can operate simultaneously. 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 Am29DL640H can be organized as both a top and bottom boot sector configuration.

The command register itself does not occupy any addressable memory location. The register is a latch used to 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. Tables 1-2 lists the device bus operations, the inputs and control levels they require, and the resulting output. The following subsections describe each of these operations in further detail. 10 Am75DL9608HG November 17, 2003 ADVANCE Table 1.

If WP#/ACC = VIL, the boot sectors will be protected. If WP#/ACC = VIH the boot sectors protection will be removed. If WP#/ACC = VACC (9V), the program time will be reduced by 40%. 5. The sector protect and sector unprotect functions may also be implemented via programming equipment. See the “Sector/Sector Block Protection and Unprotection” section. 6. 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 will be unprotected. 7. Only one flash device should be accessed at a time. For Am29DL640H flash access, CE#f1 = VIL, CE#f2 = VIH. For Am29DL320G flash access, CE#f1 = VIH, CE#f2 = ViL. 8. CE#1s= VIL, CE2s= VIH, CE#f1=VIH and CE#f2=VIH when accessing pseudo SRAM.

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 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. Refer to the AC Read-Only Operations table for timing specifications and to Figure 14 for the timing diagram. ICC1 in the DC Characteristics table represents the active current specification for reading array data. 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 VHH must not be asserted on WP#/ACC 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. See “Write Protect (WP#)” on page 23 for related information. 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 DQ15–DQ0. Standard read cycle timings apply in this mode. Refer to the Sector/Sector Block Protection and Unprotection and Autoselect Command Sequence sections for more information. 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. 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 “Byte/Word Program Command Sequence” section has details on programming data to the device using both standard and Unlock Bypass command sequences. An erase operation can erase one sector, multiple sectors, or the entire device. Table 2 indicates the address space that each sector occupies. Similarly, a “sector address” is the address bits required to uniquely select a sector. The “Flash Command Definitions” section has details on erasing a sector or the entire chip, or suspending/resuming the erase operation. The device address space is divided into four banks. A “bank address” is the address bits required to uniquely select a bank. ICC2 in the DC Characteristics table represents the active current specification for the write mode. The Flash AC 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 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 19 shows how read and write cycles may be initiated for simultaneous operation with zero latency. ICC6f and ICC7f in the 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 and RESET# pins are both held at VCC ± 0.3 V. (Note that this is a more restricted voltage range than V IH .) If CE#f and RESET# are held at V IH , but not within VCC ± 0.3 V, the device will be in the standby mode, but the standby current will be greater. The de- 12 Am75DL9608HG November 17, 2003 ADVANCE INFORMATION 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±0.3 V, the device draws CMOS standby current (I CC4 f). If RESET# is held at VIL but not within VSS±0.3 V, the standby current will be greater. The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the Flash memory, enabling the system to read the boot-up firmware from the Flash memory. If RESET# is asserted during a program or erase operation, the RY/BY# pin remains a “0” (busy) until the internal reset operation is complete, which requires a time of tREADY (during Embedded Algorithms). The system can thus monitor RY/BY# to determine whether the reset operation is complete. If RESET# is asserted when a program or erase operation is not executing (RY/BY# pin is “1”), the reset operation is completed within a time of tREADY ( not during Embedded Algorithms). The system can read data tRH a fter the RESET# pin returns to VIH. Refer to the Flash AC Characteristics tables for RESET# parameters and to Figure 15 for the timing diagram. vice requires standard access time (tCE) for read access when the device is in either of these standby modes, before it is ready to read data. If the device is deselected during erasure or programming, the device draws active current until the operation is completed. ICC3f in the table represents 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 t ACC + 30 ns. 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. ICC5f in the table represents the automatic sleep mode current specification. RESET#: Hardware Reset Pin The RESET# pin provides a hardware method of resetting the device to reading array data. When the RESET# pin is driven low for at least a period of tRP, the device immediately terminates any operation in progress, tristates all output pins, and ignores all read/write commands for the duration of the RESET# pulse. The device also resets the internal state machine to reading array data. The operation that was interrupted should be reinitiated once the device is 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. November 17, 2003 Am75DL9608HG 13 ADVANCE Table 2.

Table 12. WP# Input Voltage Sector protection/unprotection 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 24 shows the timing diagram. For sector unprotect, all unprotected sectors must first be protected prior to the first sector unprotect write cycle. Note that 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 Unprotect”. The device is shipped with all sectors unprotected. AMD offers the option of programming and protecting sectors at its factory prior to shipping the device through AMD’s ExpressFlash™ Service. Contact an AMD representative for details. It is possible to determine whether a sector is protected or unprotected. See the Sector/Sector Block Protection and Unprotection section for details. WP#/ACC Modes Am29DL640H Disables programming and erasing in SA0, SA1, SA140, and SA141 Enables programming and erasing in SA0, SA1, SA140, and SA141 Am29DL320G Disables programming and erasing in SA0 and SA1 or SA69 and SA70 Enables programming and erasing in SA0 and SA1 or SA60 and SA70 VIL VIH VHH Enables accelerated programming (ACC). See “Accelerated Program Operation” on page 11. Temporary Sector 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 Table 9). 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. 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 23 shows the timing diagrams, for this feature. If the WP#/ACC pin is at VIL while the Am29DL640H is enabled, sectors 0, 1, 140, and 141 of that device will remain protected during the Temporary sector Unprotect mode. Similarly, If the WP#/ACC pin is at VIL while the Am29DL320G is enabled, the two outermost boot sectors (SA0 and 1 on bottom boot devices or SA69 and 70 on top boot devices) of that device will remain protected during the Temporary sector Unprotect mode. Write Protect (WP#) The Write Protect function provides a hardware method of protecting without using VID. This function is one of two provided by the WP#/ACC pin. If the system asserts VIL o n the WP#/ACC pin while the Am29DL640H is enabled (CE#f1), the device disables program and erase functions in sectors 0, 1, 140, and 141, independently of whether those sectors were protected or unprotected using the method described in “Sector/Sector Block Protection and Unprotection”. Similarly, the two outermost boot sectors (SA0 and 1 on bottom boot devices or SA69 and 70 on top boot devices) on the Am29DL320G are protected when VIL i s asserted on the WP#/ACC pin while the Am29DL320G is enabled (CE#f2). If the system asserts VIH on the WP#/ACC pin, the device reverts to whether the aforementioned sectors were last set to be protected or unprotected. That is, sector protection or unprotection for these sectors depends on whether they were last protected or unprotected using the method described in “Sector/Sector Block Protection and Unprotection”. 24 Am75DL9608HG November 17, 2003 ADVANCE INFORMATION START RESET# = VID (Note 1) Perform Erase or Program Operations RESET# = VIH Temporary Sector Unprotect Completed (Note 2) Notes: 1.

The SecSi Sector is 256 bytes in length, and uses a SecSi Sector Indicator Bit (DQ7) to indicate whether or not the SecSi Sector is locked when shipped from the factory. This bit is permanently set at the factory and cannot be changed, which prevents cloning of a factory locked part. This ensures the security of the ESN once the product is shipped to the field. AMD offers the device with the SecSi Sector either fac t or y l ocke d or c u s t om e r l o ckabl e. T he fac tory-locked version is always protected when shipped from the factory, and has the SecSi (Secured Silicon) Sector Indicator Bit permanently set to a “1.” The customer-lockable version is shipped with the SecSi Sector unprotected, allowing customers to utilize the that sector in any manner they choose. The customer-lockable version has the SecSi (Secured Silicon) Sector Indicator Bit permanently set to a “0.” Thus, the SecSi Sector Indicator Bit prevents customer-lockable devices from being used to replace devices that are factory locked. The system accesses the SecSi Sector Secure Sector through a command sequence (see “Enter SecSi™ Sector/Exit SecSi Sector Command Sequence”). After the system has written the Enter SecSi Sector command sequence, it may read the SecSi Sector by using the addresses normally occupied by the boot sectors. This mode of operation continues until the system issues the Exit SecSi Sector command sequence, or until power is removed from the device. Note that the ACC function and unlock bypass modes are not available when the SecSi Sector is enabled. On power-up, or following a hardware reset, the device reverts to sending commands to the first 256 bytes of Sector 0. Factory Locked: SecSi Sector Programmed and Protected At the Factory In a factory locked device, the SecSi Sector is protected when the device is shipped from the factory. The SecSi Sector cannot be modified in any way. The device is preprogrammed with both a random number and secure ESNs. See Table 13 for address location details. Am29DL640H Am29DL320GB (Bottom boot) Am29DL320GT (Top boot) The device is available preprogrammed with one of the following: ■ Random number and secure ESNs only ■ Customer code through the ExpressFlash service ■ Random number, secure ESNs, and customer code through the ExpressFlash service. Customers may opt to have their code programmed by AMD through the AMD ExpressFlash service. AMD programs the customer’s code, with or without the random ESN. The devices are then shipped from AMD’s factory with the SecSi Sector permanently locked. Contact an AMD representative for details on using AMD’s ExpressFlash service. Customer Lockable: SecSi Sector NOT Programmed or Protected At the Factory If the security feature is not required, the SecSi Sector can be treated as an additional Flash memory space. The SecSi Sector can be read any number of times, but can be programmed and locked only once. Note that the accelerated programming (ACC) and unlock bypass functions are not available when programming the SecSi Sector. The SecSi Sector area can be protected using one of the following procedures: ■ Write the three-cycle Enter SecSi Sector Region command sequence, and then follow the in-system sector protect algorithm as shown in Figure 2, except that RESET# may be at either VIH or VID. This allows in-system protection of the SecSi Sector Region without raising any device pin to a high voltage. Note that this method is only applicable to the SecSi Sector. ■ To verify the protect/unprotect status of the SecSi Sector, follow the algorithm shown in Figure 3. Once the SecSi Sector is locked and verified, the system must write the Exit SecSi Sector Region command sequence to return to reading and writing the remainder of the array. The SecSi Sector lock must be used with caution since, once locked, there is no procedure available for unlocking the SecSi Sector area and none of the bits in the SecSi Sector memory space can be modified in any way.

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 14–17. To terminate reading CFI data, the system must write the reset command.The CFI Query mode is not accessible when the device is executing an Embedded Program or embedded Erase algorithm. 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 14–17. The system must write the reset command to return the device to reading array data.

SecSi Sector Protect Verify Hardware Data Protection The command sequence requirement of unlock cycles for programming or erasing provides data protection against inadvertent writes (refer to Table 22 for command definitions). In addition, the following hardware data protection measures prevent accidental erasure or programming, which might otherwise be caused by spurious system level signals during V CC power-up and power-down transitions, or from system noise. Low VCC Write Inhibit When VCC is less than VLKO, the device does not accept any write cycles. This protects data during VCC power-up and power-down. The command register and all internal program/erase circuits are disabled, and the device resets to the read mode. Subsequent writes are ignored until VCC is greater than VLKO. The system must provide the proper signals to the control pins to prevent unintentional writes when V CC i s greater than VLKO. Write Pulse “Glitch” Protection Noise pulses of less than 5 ns (typical) on OE#, CE#f or WE# do not initiate a write cycle. 28 Am75DL9608HG November 17, 2003 ADVANCE Table 14.

Table 22 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 Flash AC Characteristics section for timing diagrams. 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 the read mode. If the program command sequence is written to a bank that is in the Erase Suspend mode, writing the reset co m m an d re tur ns th a t ba nk to the e ra s e- s us pend-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 the read mode. 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 DQ5 goes high during a program or erase operation, writing the reset command returns the banks to the read mode (or erase-suspend-read mode if that bank was 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. Each bank is ready to read array data after completing an Embedded Program or Embedded Erase algorithm. After the device accepts an Erase Suspend command, the corresponding ban k enters the erase-suspend-read mode, after which the system can read data from any non-erase-suspended sector within the same bank. The system can read array data using the standard read timing, 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 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 DQ5 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 section for more information. The Read-Only Operations table provides the read parameters, and Figure 14 shows the timing diagram. 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. The autoselect command sequence may be written to an address within a bank that is either in the read or erase-suspend-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. The bank then enters the autoselect mode. The system may read any number of autoselect codes without reinitiating the command sequence. Table 22 shows the address and data requirements. To determine sector protection information, the system must write to the appropriate bank address (BA) and sector address (SADD). Table 2 shows the address range and bank number associated with each sector. The system must write the reset command to return to the read mode (or erase-suspend-read mode if the bank was previously in Erase Suspend). 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 the read mode. Once erasure begins, however, the device ignores reset commands until the operation is complete. Enter SecSi™ Sector/Exit SecSi Sector Command Sequence The SecSi Sector region provides a secured data area containing a random, sixteen-byte electronic serial number (ESN). The system can access the SecSi Sector region by issuing the three-cycle Enter SecSi November 17, 2003 Am75DL9608HG 35 ADVANCE INFORMATION DQ6 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.” 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. That bank 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 22 shows the requirements for the command sequence. During the unlock bypass mode, only the Unlock Bypass Program and Unlock Bypass Reset commands are valid. To exit the unlock bypass mode, the system must issue the two-cycle unlock bypass reset command sequence (See Table 12). 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 V HH a ny 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 16 for timing diagrams. Sector command sequence. The device continues to access the SecSi Sector region until the system issues the four-cycle Exit SecSi Sector command sequence. The Exit SecSi Sector command sequence returns the device to normal operation. The SecSi Sector is not accessible when the device is executing an Embedded Program or embedded Erase algorithm. Table 22 shows the address and data requirements for both command sequences. Note that the ACC function and unlock bypass modes are not available when the SecSi sector is enabled. See also “SecSi™ (Secured Silicon) Sector SectorFlash Memory Region” for further information. Program Command Sequence 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 22 shows the address and data requirements for the byte program command sequence. Note that the SecSi Sector, autoselect, and CFI functions are unavailable when a program operation is in progress. When the Embedded Program algorithm is complete, that bank then returns to the read mode and addresses are no longer latched. The system can determine the status of the program operation by using DQ7, DQ6, or RY/BY#. Refer to the Flash 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 the read mode, to ensure data integrity. Programming is allowed in any sequence and across sector boundaries. A b it cannot be programmed from “0” back to a “1.” A ttempting to do so may cause that bank to set DQ5 = 1, or cause the DQ7 and 36 Am75DL9608HG November 17, 2003 ADVANCE INFORMATION 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 18 section for timing diagrams. START Write Program Command Sequence Embedded Program algorithm in progress Data Poll from System 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 22 shows the address and data requirements for the sector erase comm a n d s e q u e n c e. N o te t h a t t h e S e cS i S e ct o r, autoselect, and CFI functions are unavailable when a erase operation is in progress. 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 time-out of 80 µs occurs. 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 80 µs, 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 the read mode. The system must rewrite the command sequence and any additional addresses and commands. The system can monitor DQ3 to determine if the sector erase timer has timed out (See the section on DQ3: Sector Erase Timer.). The time-out begins from the rising edge of the final WE# pulse in the command sequence. 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 Verify Data? No Yes No Increment Address Last Address? Yes Programming Completed Note: See Table 22 for program command sequence. Figure 4. Program Operation Chip Erase Command Sequence Chip erase is a six bus cycle operation. The chip erase command sequence is initiated by writing two unlock cycles, followed by a set-up command. Two additional unlock write cycles are then followed by the chip erase command, which in turn invokes the Embedded Erase algorithm. The device does not require the system to preprogram prior to erase. The Embedded Erase algorithm automatically preprograms and verifies the entire memory for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or timings during these operations. Table 22 shows the address and data requirements for the chip erase command sequence. Note that the SecSi Sector, autoselect, and CFI functions are unavailable when a erase operation is in progress. When the Embedded Erase algorithm is complete, that bank returns to the read mode and addresses are no longer latched. The system can determine the status of the erase operation by using DQ7, DQ6, DQ2, or RY/BY#. Refer to the Flash Write Operation Status section for information on these status bits. November 17, 2003 Am75DL9608HG 37 ADVANCE INFORMATION data from the non-erasing bank. The system can determine the status of the erase operation by reading DQ7, DQ6, DQ2, or RY/BY# in the erasing bank. Refer to the Flash 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 18 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. The bank address is required when writing this command. This command is valid only during the sector erase operation, including the 80 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 time-out, the device immediately terminates the time-out period and suspends the erase operation. Addresses are “don’t-cares” when writing the Erase suspend command. 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 DQ7–DQ0. The system can use DQ7, or DQ6 and DQ2 together, to determine if a sector is actively erasing or is erase-suspended. Refer to the Flash 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 DQ7 or DQ6 status bits, just as in the standard Byte Program operation. Refer to the Flash Write Operation Status section for more information. In the erase-suspend-read mode, the system can also issue the autoselect command sequence. 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. Refer to the Sector/Sector Block Protection and Unprotection and Autoselect Command Sequence sections for details. To resume the sector erase operation, the system must write the Erase Resume command (address bits are don’t care). The bank address of the erase-suspended bank is required 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.

Notes: 1. See Tables 1 to 2 for description of bus operations. 2. All values are in hexadecimal. 3. Except for the read cycle and the fourth cycle of the autoselect command sequence, all bus cycles are write cycles. 4. Data bits DQ15–DQ8 are don’t care in command sequences, except for RD and PD. 5. Unless otherwise noted, address bits A21–A12 are don’t cares for unlock and command cycles, unless SADD or PA is required. 6. No unlock or command cycles required when bank is reading array data. 7. The Reset command is required to return to the read mode (or to the erase-suspend-read mode if previously in Erase Suspend) when a bank is in the autoselect mode, or if DQ5 goes high (while the bank is providing status information). 8. The fourth cycle of the autoselect command sequence is a read cycle. The system must provide the bank address to obtain the manufacturer ID, device ID, or SecSi Sector factory protect information. Data bits DQ15–DQ8 are don’t care. See the Autoselect Command Sequence section for more information. 9. The device ID must be read across the fourth, fifth, and sixth cycles. At address x0E, the data is 02h for Am29DL640H and 0Ah for Am29DL320G. At address x0F, the data is 01h for 10. 11. 12. 13. 14. 15. 16. Am29DL640H and Am29DL320G (top boot) and 00h for Am29DL320G (bottom boot). For Am29DL640H, the data is 80h for factory locked, 40h for customer locked and 00h for not locked. For Am29DL320G, they are 81H and 01h respectively. The data is 00h for an unprotected sector/sector block and 01h for a protected sector/sector block. The Unlock Bypass command is required prior to the Unlock Bypass Program command. The Unlock Bypass Reset command is required to return to the read mode when the bank is in the unlock bypass mode. The system may read and program in non-erasing sectors, or enter the autoselect mode, when in the Erase Suspend mode. The Erase Suspend command is valid only during a sector erase operation, and requires the bank address. The Erase Resume command is valid only during the Erase Suspend mode, and requires the bank address. Command is valid when device is ready to read array data or when device is in autoselect mode. November 17, 2003 Am75DL9608HG 39 ADVANCE INFORMATION FLASH WRITE OPERATION STATUS The device provides several bits to determine the status of a program or erase operation: DQ2, DQ3, DQ5, DQ6, and DQ7. Table 23 and the following subsections describe the function of these bits. DQ7 and DQ6 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. pleted the program or erase operation and DQ7 has valid data, the data outputs on DQ15–DQ0 may be still invalid. Valid data on DQ15–DQ0 (or DQ7–DQ0 for byte mode) will appear on successive read cycles. Table 23 shows the outputs for Data# Polling on DQ7. Figure 5 shows the Data# Polling algorithm. Figure 20 in the Flash AC Characteristics section shows the Data# Polling timing diagram. DQ7: Data# Polling The Data# Polling bit, DQ7, indicates to the host system whether an Embedded Program or Erase algorithm is in progress or completed, or whether a bank is in Erase Suspend. Data# Polling is valid after the rising edge of the final WE# pulse in the command sequence. During the Embedded Program algorithm, the device outputs on DQ7 the complement of the datum programmed to DQ7. This DQ7 status also applies to programming during Erase Suspend. When the Embedded Program algorithm is complete, the device outputs the datum programmed to DQ7. The system must provide the program address to read valid status information on DQ7. If a program address falls within a protected sector, Data# Polling on DQ7 is active for approximately 1 µs, then that bank returns to the read mode. During the Embedded Erase algorithm, Data# Polling produces a “0” on DQ7. When the Embedded Erase algorithm is complete, or if the bank enters the Erase Suspend mode, Data# Polling produces a “1” on DQ7. The system must provide an address within any of the sectors selected for erasure to read valid status information on DQ7. After an erase command sequence is written, if all sectors selected for erasing are protected, Data# Polling on DQ7 is active for approximately 100 µs, then the bank returns to the read mode. 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 DQ7 at an address within a protected sector, the status may not be valid. When the system detects DQ7 has changed from the complement to true data, it can read valid data at DQ15–DQ0 (or DQ7–DQ0 for byte mode) on the following read cycles. Just prior to the completion of an Embedded Program or Erase operation, DQ7 may change asynchronously with DQ15–DQ8 (DQ7–DQ0 in byte mode) while Output Enable (OE#) is asserted low. That is, the device may change from providing status information to valid data on DQ7. Depending on when the system samples the DQ7 output, it may read the status or valid data. Even if the device has comSTART Read DQ7–DQ0 Addr = VA DQ7 = Data? Yes No No DQ5 = 1? Yes Read DQ7–DQ0 Addr = VA DQ7 = Data? Yes No FAIL PASS Notes: 1. VA = Valid address for programming. During a sector erase operation, a valid address is any sector address within the sector being erased. During chip erase, a valid address is any non-protected sector address. 2. DQ7 should be rechecked even if DQ5 = “1” because DQ7 may change simultaneously with DQ5. Figure 6. Data# Polling Algorithm 40 Am75DL9608HG November 17, 2003 ADVANCE INFORMATION DQ6 also toggles during the erase-suspend-program mode, and stops toggling once the Embedded Program algorithm is complete. Table 23 shows the outputs for Toggle Bit I on DQ6. Figure 6 shows the toggle bit algorithm. Figure 21 in the “Flash AC Characteristics” section shows the toggle bit timing diagrams. Figure 22 shows the differences between DQ2 and DQ6 in graphical form. See also the subsection on DQ2: Toggle Bit II. RY/BY#: Ready/Busy# The RY/BY# is a dedicated, open-drain output pin which 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 in the read mode, the standby mode, or one of the banks is in the erase-suspend-read mode. Table 23 shows the outputs for RY/BY#. START DQ6: Toggle Bit I Toggle Bit I on DQ6 indicates whether an Embedded Program or Erase algorithm is in progress or complete, or whether the device has entered the Erase Suspend mode. Toggle Bit I may be read at any address, and is valid after the rising edge of the final WE# pulse in the command sequence (prior to the program or erase operation), and during the sector erase time-out. During an Embedded Program or Erase algorithm operation, successive read cycles to any address cause DQ6 to toggle. The system may use either OE# or CE#f to control the read cycles. When the operation is complete, DQ6 stops toggling. After an erase command sequence is written, if all sectors selected for erasing are protected, DQ6 toggles for approximately 100 µs, then returns to reading array data. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. The system can use DQ6 and DQ2 together to determine whether a sector is actively erasing or is erase-suspended. When the device is actively erasing (that is, the Embedded Erase algorithm is in progress), DQ6 toggles. When the device enters the Erase Suspend mode, DQ6 stops toggling. However, the system must also use DQ2 to determine which sectors are erasing or erase-suspended. Alternatively, the system can use DQ7 (see the subsection on DQ7: Data# Polling). If a program address falls within a protected sector, DQ6 toggles for approximately 1 µs after the program command sequence is written, then returns to reading array data. Read Byte (DQ7–DQ0) Address =VA Read Byte (DQ7–DQ0) Address =VA Toggle Bit = Toggle? Yes No No DQ5 = 1? Yes Read Byte Twice (DQ7–DQ0) Address = VA Toggle Bit = Toggle? No Yes Program/Erase Operation Not Complete, Write Reset Command Program/Erase Operation Complete Note: The system should recheck the toggle bit even if DQ5 = “1” because the toggle bit may stop toggling as DQ5 changes to “1.” See the subsections on DQ6 and DQ2 for more information. Figure 7. Toggle Bit Algorithm November 17, 2003 Am75DL9608HG 41 ADVANCE INFORMATION not gone high. The system may continue to monitor the toggle bit and DQ5 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). DQ2: Toggle Bit II The “Toggle Bit II” on DQ2, when used with DQ6, indicates whether a particular sector is actively erasing (that is, the Embedded Erase algorithm is in progress), or whether that sector is erase-suspended. Toggle Bit II is valid after the rising edge of the final WE# pulse in the command sequence. DQ2 toggles when the system reads at addresses within those sectors that have been selected for erasure. (The system may use either OE# or CE#f to control the read cycles.) But DQ2 cannot distinguish whether the sector is actively erasing or is erase-suspended. DQ6, by comparison, indicates whether the device is actively erasing, or is in Erase Suspend, but cannot distinguish which sectors are selected for erasure. Thus, both status bits are required for sector and mode information. Refer to Table 23 to compare outputs for DQ2 and DQ6. Figure 6 shows the toggle bit algorithm in flowchart form, and the section “DQ2: Toggle Bit II” explains the algorithm. See also the DQ6: Toggle Bit I subsection. Figure 21 shows the toggle bit timing diagram. Figure 22 shows the differences between DQ2 and DQ6 in graphical form. DQ5: Exceeded Timing Limits DQ5 indicates whether the program or erase time has exceeded a specified internal pulse count limit. Under these conditions DQ5 produces a “1,” indicating that the program or erase cycle was not successfully completed. The device may output a “1” on DQ5 if the system tries to program a “1” to a location that was previously programmed to “0.” O nly 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, DQ5 produces a “1.” Under both these conditions, the system must write the reset command to return to the read mode (or to the erase-suspend-read mode if a bank was previously in the erase-suspend-program mode). DQ3: Sector Erase Timer After writing a sector erase command sequence, the system may read DQ3 to determine whether or not erasure 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 period is complete, DQ3 switches from a “0” to a “1.” If the time between additional sector erase commands from the system can be assumed to be less than 50 µs, the system need not monitor DQ3. See also the Sector Erase Command Sequence section. After the sector erase command is written, the system should read the status of DQ7 (Data# Polling) or DQ6 (Toggle Bit I) to ensure that the device has accepted the command sequence, and then read DQ3. If DQ3 is “1,” the Embedded Erase algorithm has begun; all further commands (except Erase Suspend) are ignored until the erase operation is complete. If DQ3 is “0,” the device will accept additional sector erase commands. To ensure the command has been accepted, the system software should check the status of DQ3 prior to and following each subsequent sector erase command. If DQ3 is high on the second status check, the last command might not have been accepted. Table 23 shows the status of DQ3 relative to the other status bits. Reading Toggle Bits DQ6/DQ2 Refer to Figure 6 for the following discussion. Whenever the system initially begins reading toggle bit status, it must read DQ15–DQ0 (or DQ7–DQ0 for byte mode) 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 DQ15–DQ0 (or DQ7–DQ0 for byte mode) on the following read cycle. However, if after the initial two read cycles, the system determines that the toggle bit is still toggling, the system also should note whether the value of DQ5 is high (see the section on DQ5). If it is, the system should then determine again whether the toggle bit is toggling, since the toggle bit may have stopped toggling just as DQ5 went high. If the toggle bit is no longer toggling, the device has successfully completed the program or erase operation. If it is still toggling, the device did not completed the operation successfully, and the system must write the reset command to return to reading array data. The remaining scenario is that the system initially determines that the toggle bit is toggling and DQ5 has 42 Am75DL9608HG November 17, 2003 ADVANCE Table 23.

Typical program and erase times assume the following conditions: 25°C, 3.0 V VCC, 1,000,000 cycles. Additionally, programming typicals assume checkerboard pattern. 2. Under worst case conditions of 90°C, VCC = 2.7 V, 1,000,000 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 program times 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 two- or four-bus-cycle sequence for the program command. See Table 22 for further information on command definitions. 6. The device has a minimum erase and program cycle endurance of 1,000,000 cycles.
