The Am29F800B is an 8 Mbit, 5.0 volt-only Flash memory organized as 1,048,576 bytes or 524,288 words. The device is offered in 44-pin SO, 48-pin TSOP, and 48-ball FBGA packages. The device is also available in Known Good Die (KGD) form. For more information, refer to publication number 21631. The word-wide data (x16) appears on DQ15–DQ0; the byte-wide (x8) data appears on DQ7–DQ0. This device is designed to be programmed in-system with the stan dard system 5.0 volt V CC supply. A 12.0 V V PP is not required for write or erase operations. The device can also be programmed in standard EPROM program mers. This device is manufactured using AMD’s 0.32 µm process technology, and offers all the features and ben efits of the Am29F800, which was manufactured using 0.5 µm process technology. The standard device offers access times of 55, 70, 90, and 120 ns, allowing high speed microprocessors to operate without wait states. To eliminate bus contention the device has separate chip enable (CE#), write enable (WE#) and output enable (OE#) controls. The device requires only a single 5.0 volt power sup- ply for both read and write functions. Internally gener - ated and regulated voltages are provided for the program and erase operations. The device is entirely command set compatible with the JEDEC single-power-supply Flash standard . Com- mands are written to the command register using stan- dard microprocessor write timings. Register contents serve as input to an internal state-machine that con - trols the erase and programming circuitry. Write cycles also internally latch addresses and data needed for the programming and erase operations. Reading data out of the device is similar to reading from other Flash or EPROM devices. Device programming occurs by executing the program command sequence. This initiates the Embedded Program algorithm—an internal algorithm that auto matically times the program pulse widths and verifies proper cell margin. Device erasure occurs by executing the erase com - mand sequence. This initiates the Embedded Erase algorithm—an internal algorithm that automatically preprograms the array (if it is not already programmed) before executing the erase operation. During erase, the device automatically times the erase pulse widths and verifies proper cell margin. The host system can detect whether a program or erase operation is complete by observing the RY/BY# pin, or by reading the DQ7 (Data# Polling) and DQ6 (toggle) status bits. After a program or erase cycle has been completed, the device is ready to read array data or accept another command. The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the data 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 opera - tions during power transitions. The hardware sector protection feature disables both program and erase operations in any combination of the sectors of mem - ory. This can be achieved via programming equipment. The Erase Suspend feature enables the user to put erase on hold for any period of time to read data from, or program data to, any sector that is not selected for erasure. True background erase can thus be achieved. The hardware RESET# pin terminates any operation in progress and resets the internal state machine to reading array data. The RESET# pin may be tied to the system reset circuitry. A sys tem reset would thus also reset the device, enabling the system microprocessor to read the boot-up firmware from the Flash memory. The system can place the device into the standby mode . Power consumption is greatly reduced in this mode. AMD’s Flash technology combines years of Flash memory manufacturing experience to produce the highest levels of quality, reliability and cost effective ness. The device electrically erases all bits within a sector simultaneously via Fowler-Nordheim tunneling. The data is programmed using hot electron injection.

tions” section for details on erasing a sector or the en - tire chip, or suspending/resuming the erase operation. After the system writes the autoselect command se - quence, the device enters the autoselect mode. The system can then read autoselect codes from the inter - nal register (which is separate from the memory array) on DQ7–DQ0. Standard read cycle timings apply in this mode. Refer to the “Autoselect Mode” and “Autoselect Command Sequence” sections for more information. ICC2 in the DC Characteristics table represents the ac- tive current specification for the write mode. The “AC Characteristics” section contains timing specification tables and timing diagrams for write operations. Program and Erase Operation Status During an erase or program operation, the system may check the status of the operation by reading the status bits on DQ7–DQ0. Standard read cycle timings and I CC read specifications apply. Refer to “Write Operation Status” for more information, and to each AC Charac - teristics section for timing diagrams. 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, inde pendent of the OE# input. The device enters the CMOS standby mode when CE# and RESET# pins are both held at V CC ± 0.5 V. (Note that this is a more restricted voltage range than V IH.) The device enters the TTL standby mode when CE# and RESET# pins are both held at V IH. The device re- quires standard access time (tCE) for read access when the device is in either of these standby modes, before it is ready to read data. The device also enters the standby mode when the RE- SET# pin is driven low. Refer to the next section, “RE- SET#: Hardware Reset Pin”. If the device is deselected during erasure or program - ming, the device draws active current until the operation is completed. In the DC Characteristics tables, I CC3 represents the standby current specification. RESET#: Hardware Reset Pin The RESET# pin provides a hardware method of reset- ting the device to reading array data. When the system drives the RESET# pin low for at least a period of t RP, 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 ma chine to reading array data. The operation that was in- terrupted 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 V IL, the device enters the TTL standby mode; if RESET# is held at V SS ± 0.5 V, the device enters the CMOS standby mode. The RESET# pin may be tied to the system reset cir - cuitry. A system reset would thus also reset the Flash memory, enabling the system to read the boot-up firm ware from the Flash memory. If RESET# is asserted during a program or erase oper- ation, the RY/BY# pin remains a “0” (busy) until the in- ternal reset operation is complete, which requires a time of t READY (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 t READY (not during Embedded Algo - rithms). The system can read data t RH after the RE - SET# pin returns to VIH. Refer to the AC Characteristics tables for RESET# pa- rameters and timing diagram. Output Disable Mode When the OE# input is at VIH, output from the device is disabled. The output pins are placed in the high imped- ance state.

The command sequence requirement of unlock cycles for programming or erasing provides data protection against inadvertent writes (refer to the Command Defi nitions table). In addition, the following hardware data protection measures prevent accidental erasure or pro gramming, which might otherwise be caused by spuri - ous 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 V LKO, the device does not ac - cept any write cycles. This protects data during V CC power-up and power-down. The command register and all internal program/erase circuits are disabled, and the device resets. Subsequent writes are ignored until V CC is greater than V LKO. The system must provide the proper signals to the control pins to prevent uninten - tional writes when VCC is greater than VLKO. Write Pulse “Glitch” Protection Noise pulses of less than 5 ns (typical) on OE#, CE# or WE# do not initiate a write cycle. Logical Inhibit Write cycles are inhibited by holding any one of OE# = V IL, CE# = V IH or WE# = V IH. To initiate a write cycle, CE# and WE# must be a logical zero while OE# is a logical one. Power-Up Write Inhibit If WE# = CE# = VIL and OE# = VIH during power up, the device does not accept commands on the rising edge of WE#. The internal state machine is automatically reset to reading array data on power-up. COMMAND DEFINITIONS Writing specific address and data commands or se - quences into the command register initiates device op- erations. The Command Definitions table defines the valid register command sequences. Writing incorrect address and data values or writing them in the im proper sequence resets the device to reading array data. All addresses are latched on the falling edge of WE# or CE#, whichever happens later. All data is latched on the rising edge of WE# or CE#, whichever happens first. Refer to the appropriate timing diagrams in the “AC Characteristics” section. 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 Em bedded Erase algorithm. After the device accepts an Erase Suspend command, the device enters the Erase Suspend mode. The sys tem can read array data using the standard read tim - ings, except that if it reads at an address within erase- suspended sectors, the device outputs status data. After completing a programming operation in the Erase Suspend mode, the system may once again read array data with the same exception. See “Erase Sus - pend/Erase Resume Commands” for more information on this mode. The system must issue the reset command to re-en - able the device for reading array data if DQ5 goes high, or while in the autoselect mode. See the “Reset Com- mand” section, next. See also “Requirements for Reading Array Data” in the “Device Bus Operations” section for more information. The Read Operations table provides the read parame- ters, and Read Operation Timings diagram shows the timing diagram. Reset Command Writing the reset command to the device resets the de- vice to reading array data. Address bits are don’t care for this command. The reset command may be written between the se - quence cycles in an erase command sequence before erasing begins. This resets the device to reading array data. Once erasure begins, however, the device ig nores reset commands until the operation is complete. The reset command may be written between the se - quence cycles in a program command sequence be - fore programming begins. This resets the device to reading array data (also applies to programming in Erase Suspend mode). Once programming begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the se - quence cycles in an autoselect command sequence. Once in the autoselect mode, the reset command must be written to return to reading array data (also applies to autoselect during Erase Suspend). If DQ5 goes high during a program or erase operation, writing the reset command returns the device to read ing array data (also applies during Erase Suspend).

Any commands written to the chip during the Embed - ded Erase algorithm are ignored. Note that a hardware reset during the chip erase operation immediately ter - minates the operation. The Chip Erase command se - quence should be reinitiated once the device has returned to reading array data, to ensure data integrity. The system can determine the status of the erase operation by using DQ7, DQ6, DQ2, or RY/BY#. See “Write Operation Status” for information on these status bits. When the Embedded Erase algorithm is complete, the device returns to reading array data and addresses are no longer latched. Figure 3 illustrates the algorithm for the erase opera - tion. See the Erase/Program Operations tables in “AC Characteristics” for parameters, and to the Chip/Sector Erase Operation Timings for timing waveforms. Sector Erase Command Sequence Sector erase is a six bus cycle operation. The sector erase command sequence is initiated by writing two un- lock cycles, followed by a set-up command. Two addi - tional unlock write cycles are then followed by the address of the sector to be erased, and the sector erase command. The Command Definitions table shows the address and data requirements for the sec tor erase command sequence. The device does not require the system to preprogram the memory prior to erase. The Embedded Erase algo- rithm automatically programs and verifies the sector for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or tim ings during these operations. After the command sequence is written, a sector erase time-out of 50 µs begins. During the time-out period, additional sector addresses and sector erase com mands may be written. Loading the sector erase buffer may be done in any sequence, and the number of sec tors may be from one sector to all sectors. The time be- tween these additional cycles must be less than 50 µs, otherwise the last address and command might not be accepted, and erasure may begin. It is recommended that processor interrupts be disabled during this time to ensure all commands are accepted. The interrupts can be re-enabled after the last Sector Erase command is written. If the time between additional sector erase commands can be assumed to be less than 50 µs, the system need not monitor DQ3. Any command other than Sector Erase or Erase Suspend during the time-out period resets the device to reading array data. The system must rewrite the command sequence and any additional sector addresses and commands. The system can monitor DQ3 to determine if the sector erase timer has timed out. (See the “DQ3: Sector Erase Timer” section.) The time-out begins from the rising edge of the final WE# pulse in the command sequence. Once the sector erase operation has begun, only the Erase Suspend command is valid. All other commands are ignored. Note that a hardware reset during the sector erase operation immediately terminates the op eration. The Sector Erase command sequence should be reinitiated once the device has returned to reading array data, to ensure data integrity. When the Embedded Erase algorithm is complete, the device returns to reading array data and addresses are no longer latched. The system can determine the sta tus of the erase operation by using DQ7, DQ6, DQ2, or RY/BY#. Refer to “Write Operation Status” for informa- tion on these status bits. Figure 3 illustrates the algorithm for the erase opera - tion. Refer to the Erase/Program Operations tables in the “AC Characteristics” section for parameters, and to the Sector Erase Operations Timing diagram for timing waveforms. Erase Suspend/Erase Resume Commands The Erase Suspend command allows the system to in- terrupt 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 algo rithm. Writing the Erase Suspend command during the Sector Erase time-out immediately terminates the time-out period and suspends the erase operation. Ad dresses are “don’t-cares” when writing the Erase Sus- pend command. When the Erase Suspend command is written during a 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 ter minates the time-out period and suspends the erase operation. After the erase operation has been suspended, the system can read array data from or program data to any sector not selected for erasure. (The device “erase suspends” all sectors selected for erasure.) Normal read and write timings and command definitions apply. Reading at any address within erase-suspended sec tors produces status da ta 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. See “Write Operation Status” for information on these status bits. After an erase-suspended program operation is com - plete, the system can once again read array data within non-suspended sectors. The system can determine the status of the program operation using the DQ7 or

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, sev eral RY/BY# pins can be tied together in parallel with a pull-up resistor to V CC. 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 6 shows the outputs for RY/BY#. The timing dia- grams for read, reset, program, and erase shows the relationship of RY/BY# to other signals. 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 op eration), and during the sector erase time-out. During an Embedded Program or Erase algorithm op - eration, successive read cycles to any address cause DQ6 to toggle. (The system may use either OE# or CE# 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 tog gles for approximately 100 µs, then returns to reading array data. If not all selected sectors are protected, the Embedded Erase algorithm erases the unpro tected sectors, and ignores the selected sectors that are protected. The system can use DQ6 and DQ2 together to deter - mine whether a sector is acti vely 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 2 µs after the program command sequence is written, then returns to reading array data. DQ6 also toggles during the erase-suspend-program mode, and stops toggling once the Embedded Pro gram algorithm is complete. The Write Operation Status table shows the outputs for Toggle Bit I on DQ6. Refer to Figure 5 for the toggle bit algorithm, and to the Toggle Bit Timings figure in the “AC Characteristics” section for the timing diagram. The DQ2 vs. DQ6 figure shows the differences be tween DQ2 and DQ6 in graphical form. See also the subsection on “DQ2: Toggle Bit II”. DQ2: Toggle Bit II The “Toggle Bit II” on DQ2, when used with DQ6, indi- cates 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 era sure. (The system may use either OE# or CE# to con - trol the read cycles.) But DQ2 cannot distinguish whether the sector is actively erasing or is erase-sus pended. DQ6, by comparison, indicates whether the device is actively erasing, or is in Erase Suspend, but cannot distinguish which sectors are selected for era sure. Thus, both status bits are required for sector and mode information. Refer to Table 6 to compare outputs for DQ2 and DQ6. Figure 5 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. Refer to the Toggle Bit Timings figure for the toggle bit timing diagram. The DQ2 vs. DQ6 figure shows the dif ferences between DQ2 and DQ6 in graphical form. Reading Toggle Bits DQ6/DQ2 Refer to Figure 5 for the following discussion. When - ever the system initially begins reading toggle bit sta - tus, it must read DQ7–DQ0 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 sys tem can read array data on DQ7–DQ0 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 tog gling 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 complete the operation successfully, and

November 2, 2006 21504E5 Am29F800B 37 DATA SHEET ERASE AND PROGRAMMING PERFORMANCE Notes: 1. Typical program and erase times assume the following conditions: 25 °C, 5.0 V VCC, 1,000,000 cycles. Additionally, programming typicals assume checkerboard pattern. 2. Under worst case conditions of 90°C, V CC = 4.5 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 four-bus-cycle sequence for the program command. See Table 5 for further information on command definitions. 6. The device has a guaranteed minimum erase and program cycle endurance of 1,000,000 cycles. LATCHUP CHARACTERISTICS Includes all pins except VCC. Test conditions: VCC = 5.0 V, one pin at a time.
