AS8F128K32 is a 4 Megabit CMOS FLASH Memory Module organized as 128K x 32 bits. The AS8F128K32 achieves high speed access (60 to 150 ns), low power consumption and high reliability by employing advanced CMOS memory technology. The device is designed to be programmed in-system with the standard system 5.0V V CC supply. A 12.0V VPP is not required for program or erase operation. The device can also be programmed or erased in standard EPROM programmers. To eliminate bus contention the device has seperate chip enbaled (CEx\\), write enable (WEx\\) and output enable (OE) controls. The device requires only a single 5.0 volt power supply for both read and write functions. Internally generated 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. Commands are written to the command register using standard microprocessor write timings. Register contents serve as input to an internal state machine that

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 invokes the Embedded Program algorithm—an internal algorithm that automatically times the program pulse widths and verifies proper cell margin. Device erasure occurs by executing the erase command sequence. This invokes 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 reading the I/O7 (Data\\ Polling) and I/O6 (toggle) status bits. After a program or erase cycle has been completed, the device is ready to read array data or accept another command. The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the data contents of other sectors. The device is erased when shipped from the factory. The hardware data protection measures include a low V CC detector 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, and is implemented using standard EPROM programmers. The system can place the device into the standby mode. Power consumption is greatly reduced in this mode. The device electrically erases all bits within a sector simultaneously via Fowler-Nordheim tunneling. The bytes are programmed one byte at a time using the EPROM programming mechanism of hot electron injection.

DEVICE BUS OPERATIONS NOTE: All device/algorithm descriptions contained in this data sheet reference each individual die. This section describes the requirements and use of the device bus operations, which are initiated through the internal command register. The command register itself does not occupy any addressable memory location. The register is composed of latches that store the commands, along with the address and data information needed to execute the 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. Requirements for Reading Array Data To read array data from the outputs, the system must drive the CEx\\ and OE\\ pins to V IL. CEx\\ is the power control and selects the device. OE\\ is the output control and gates array data to the output pins. WEx\\ should remain at VIH. The internal state machine is set for reading array data upon device power-up. This ensures that no spurious alteration of the memory content occurs during the power transition. No command is necessary in this mode to obtain array data. Standard microprocessor read cycles that assert valid addresses on the device address inputs produce valid data on the device data outputs. The device remains enabled for read access until the command register contents are altered. See “Reading Array Data” for more information. Refer to the AC Read Operations table for timing specifications and to the Read Operations Timings diagram for the timing waveforms. I CC1 in the DC Characteristics table represents the active current specification for reading array data. 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 WEx\\ and CEx\\ to VIL, and OE\\ to VIH. An erase operation can erase one sector, multiple sectors, or the entire device. The Sector Address Tables indicate the address space that each sector occupies. A “sector address” consists of the address bits required to uniquely select a sector. See the “Command Definitions” section for details on erasing a sector or the entire chip. After the system writes the autoselect command sequence, the device enters the autoselect mode. The system can then read autoselect codes from the internal register (which is separate from the memory array) on I/O31–I/O0. Standard read cycle timings apply in this mode. Refer to the “Autoselect Mode” and “Autoselect Command Sequence” sections for more information. I CC2 in the DC Characteristics table represents the active current specification for the write mode. The “AC Characteristics” section contains timing specification tables and timing diagrams for write operations.

Rev. 2.7 09/07 Austin Semiconductor, Inc. reserves the right to change products or specifications without notice. Austin Semiconductor, Inc. Program and Erase Operation Status During an erase or program operation, the system may check the status of the operation by reading the status bits on I/O31– I/O0. Standard read cycle timings and I CC read specifications apply. Refer to “Write Operation Status” for more information, and to each AC Characteristics section in the appropriate data sheet 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, independent of the OE\\ input. The device enters the CMOS standby mode when the CEx\\ pin is 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 CEx\\ is held at V IH. The device requires the standard access time (tCE) before it is ready to read data. If the device is deselected during erasure or programming, the device draws active current until the operation is completed. ICC3 in the DC Characteristics tables represents the standby current specification. Output Disable Mode When the OE\\ input is at V IH, output from the device is disabled. The output pins are placed in the high impedance state. Autoselect Mode The autoselect mode provides manufacturer and device identification, and sector protection verification, through identifier codes output on I/O31–I/O0. This mode is primarily intended for programming equipment to automatically match a device to be programmed with its corresponding programming algorithm. However, the autoselect codes can also be accessed in-system through the command register. When using programming equipment, the autoselect mode requires V ID (11.5 V to 12.5 V) on address pin A9. Address pins A6, A1, and A0 must be as shown in Autoselect Codes (High V oltage Method) table. In addition, when verifying sector protection, the sector address must appear on the appropriate highest order address bits. Refer to the corresponding Sector Address Tables. The Command Definitions table 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/O31– I/O0. To access the autoselect codes in-system, the host system can issue the autoselect command via the command register, as shown in the Command Definitions table. This method does not require V ID. See “Command Definitions” for details on using the autoselect mode.

Rev. 2.7 09/07 Austin Semiconductor, Inc. reserves the right to change products or specifications without notice. Austin Semiconductor, Inc. Sector Protection/Unprotection The hardware sector protection feature disables both program and erase operations in any sector. The hardware sector unprotection feature re-enables both program and erase operations in previously protected sectors. Sector protection/unprotection must be implemented using programming equipment. The procedure requires a high voltage (V ID) on address pin A9 and the control pins. The device is shipped with all sectors unprotected. It is possible to determine whether a sector is protected or unprotected. See “Autoselect Mode” for details. Hardware Data Protection The command sequence requirement of unlock cycles for programming or erasing provides data protection against inadvertent writes (refer to the Command Definitions table). In addition, the following hardware data protection measures prevent accidental erasure or programming, which might otherwise be caused by spurious system level signals during 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 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. 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 VCC is greater than VLKO. Write Pulse “Glitch” Protection Noise pulses of less than 5 ns (typical) on OE\\, CEx\\ or WEx\\ do not initiate a write cycle. Logical Inhibit Write cycles are inhibited by holding any one of OE\\ = V IL, CEx\\ = VIH or WEx\\ = VIH. To initiate a write cycle, CEx\\ and WEx\\ must be a logical zero while OE\\ is a logical one. Power-Up Write Inhibit If WEx\\ = CEx\\ = VIL and OE\\ = VIH during power up, the device does not accept commands on the rising edge of WEx\\. The internal state machine is automatical ly reset to reading array data on power-up.

COMMAND DEFINITIONS Writing specific address and data commands or sequences into the command register initiates device operations. The Command Definitions table defines the valid register command sequences. Writing incorrect address and data values or writing them in the improper sequence resets the device to reading array data. All addresses are latched on the falling edge of WEx\\ or CEx\\, whichever happens later. All data is latched on the rising edge of WEx\\ or CEx\\, 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 Embedded Erase algorithm. The system must issue the reset command to re-enable the device for reading array data if I/O5* goes high, or while in the autoselect mode. See the “Reset Command” section, next. See also “Requirements for Reading Array Data” in the “Device Bus Operations” section for more information. The Read Operations table provides the read parameters, and Read Operation Timings diagram shows the timing diagram. Reset Command Writing the reset command to the device resets the device to reading array data. Address bits are don’t care for this command. The reset command may be written between the sequence cycles in an erase command sequence before erasing begins. This resets the device to reading array data. Once erasure begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in a program command sequence before programming begins. This resets the device to reading array data. 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 I/O5* goes high during a program or erase operation, writing the reset command returns the device to reading array data. Autoselect Command Sequence The autoselect command sequence allows the host system to access the manufacturer and devices codes, and determine whether or not a sector is protected. The Command Definitions table shows the address and data requirements. This method is an alternative to that shown in the Autoselect Codes (High V oltage Method) table, which is intended for PROM programmers and requires V ID on address bit A9. The autoselect command sequence is initiated by writing two unlock cycles, followed by the autoselect command. The device then enters the autoselect mode, and the system may read at any address any number of times, without initiating another command sequence. A read cycle at address XX00h or retrieves the manufacturer code. A read cycle at address XX01h returns the device code. A read cycle containing a sector address (SA) and the address 02h in returns 01h if that sector is protected, or 00h if it is unprotected. Refer to the Sector Address tables for valid sector addresses. The system must write the reset command to exit the autoselect mode and return to reading array data. Byte 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 verify the programmed cell margin. The Command Definitions take shows the address and data requirements for the byte program command sequence. When the Embedded Program algorithm is complete, the device then returns to reading array data and addresses are no longer latched. The system can determine the status of the program operation by using I/O7or I/O6. See “Write Operation Status” for information on these status bits. Any commands written to the device during the Embedded Program Algorithm are ignored. Programming is allowed in any sequence and across sector boundaries. A bit cannot be programmed from a “0” back to a “1”. Attempting to do so may halt the operation and set I/O5* to “1”, or cause the Data\\ Polling algorithm to indicate the operation was successful. However, a succeeding read will show that the data is still “0”. Only erase operations can convert a “0” to a “1”. *NOTE: applies to every 8th byte (i.e. I/O5, I/O13, I/O21, I/O29)

Rev. 2.7 09/07 Austin Semiconductor, Inc. reserves the right to change products or specifications without notice. Austin Semiconductor, Inc. WRITE OPERATION STATUS The device provides several bits to determine the status of a write operation: I/O3, I/O5, I/O6, and I/O7. Table 5 and the following subsections describe the functions 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. These three bits are discussed first. I/O7: Data\\ Polling The Data\\ Polling bit, I/O7*, indicates to the host system whether an Embedded Algorithm is in progress or completed. Data\\ Polling is valid after the rising edge of the final WEx\\ 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*. 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 2 ms, 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, Data\\ Polling produces a “1” on I/O7*. This is analogous to the complement/true datum output described for the Embedded Program algorithm: the erase function changes all the bits in a sector to “1”; prior to this, the device outputs the “complement,” or “0.” The system must provide an address within any of the sectors selected for erasure to read valid status information on I/O7*. After an erase command sequence is written, if all sectors selected for erasing are protected, Data\\ Polling on I/O7* is active for approximately 100 ms, then the device returns to reading array data. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. When the system detects I/O7* has changed from the complement to true data, it can read valid data at I/O7– I/O0 on the following read cycles. This is because I/O7* may change asynchronously with I/O0–I/O6 while Output Enable (OE\\) is asserted low. The Data\\ Polling Timings (During Embedded Algorithms) figure in the “AC Characteristics” section illustrates this. Table 5 shows the outputs for Data\\ Polling on I/O7*. Figure 3 shows the Data\\ Polling algorithm. FIGURE 3: Data\\ Polling Algorithm NOTES: 1. V A = Valid address for programming. During a sector erase operation, a valid address is an address within any sector selected for erasure. During chip erase, a valid address is any non-protected sector address. 2. I/O7 should be rechecked even if I/O5 = “1” because I/O7 may change simultaneously with I/O5. *NOTE: applies to every 8th byte.
Rev. 2.7 09/07 Austin Semiconductor, Inc. reserves the right to change products or specifications without notice. Austin Semiconductor, Inc. I/O6: Toggle Bit I Toggle Bit I on I/O6 indicates whether an Embedded Program or Erase algorithm is in progress or complete. Toggle Bit I may be read at any address, and is valid after the rising edge of the final WEx\\ 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 CEx\\ 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 or approximately 100 ms, 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. If a program address falls within a protected sector, I/O6 toggles for approximately 2 ms after the program command sequence is written, then returns to reading array data. The Write Operation Status table shows the outputs for Toggle Bit I on I/O6. Refer to Figure 4 for the toggle bit algorithm, and to the Toggle Bit Timings figure in the “AC Characteristics” section for the timing diagram. Reading Toggle Bit I/O6 Refer to Figure 4 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 4). FIGURE 4: Toggle Bit Algorithm NOTES: 1. Read toggle bit twice to determine whether or not it is toggling. See text. 2. Recheck toggle bit because it may stop toggling as I/O5 changes to “1”. See text. *NOTE: applies to every 8th byte.

ERASE AND PROGRAMMING PERFORMANCE TYP1 MAX2 UNIT Chip/Sector Erase Time 1.0 15 sec Excludes 00h programming prior to erasure4 Byte Programming Time 14 1000 µs Chip Programming Time3 1.8 12.5 sec LIMITS COMMENTSPARAMETER Excludes system-level overhead5 NOTES: 1. Typical program and erase times assume the following conditions: 25° C, 5.0 V V CC, 100,000 cycles. Additionally, programming typicals assume checkerboard pattern. 2. Under worst case conditions of 90°C, V CC = 4.5 V (4.75 V for -45, -55 PDIP), 100,000 cycles. 3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes progr am faster than the maximum byte program time listed. If the maximum byte program time given is exceeded, only then does the device set I/ O5 = 1. See the section on I/O5 for further information. 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 1 for f urther information on command definitions. 6. The device has a typical erase and program cycle endurance of 1,000,000 cycles. 100,000 cycles are guaranteed. 555 for program 2AA for erase PA for program SA for sector erase 555 for chip erase
