Publication# 25270 Rev: C Amendment: 7 Issue Date: January 31, 2007 DATA SHEET GENERAL DESCRIPTION The Am29LV128MH/L is a 128 Mbit, 3.0 volt single power supply flash memory devices organized as 8,388,608 words or 16,777,216 bytes. The device has a 16-bit wide data bus that can also function as an 8-bit wide data bus by using the BYTE# input. The device can be programmed either in the host system or in standard EPROM programmers. An access time of 90, 100, 110, or 120 ns is available. Note that each access time has a specific operating voltage range (VCC) and an I/O voltage range (VIO), as specified in “Product Selector Guide” on page 6 and the “Ordering Information” on page 10. The device is offered in a 56-pin TSOP, 64-ball Fortified BGA. Each device has separate chip enable (CE#), write enable (WE#) and output enable (OE#) controls. Each device requires only a single 3.0 volt power supply for both read and write functions. In addition to a V CC i nput, a high-voltage a ccelerated program (WP#/ACC) input provides shorter programming times through increased current. This feature is intended to facilitate factory throughput during system production, but may also be used in the field if desired. The device is entirely command set compatible with the JEDEC single-power-supply Flash standard . Commands are written to the device using standard microprocessor write timing. Write cycles also internally latch addresses and data needed for the programming and erase operations. 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. Device programming and erasure are initiated through command sequences. Once a program or erase operation has begun, the host system need only poll the DQ7 (Data# Polling) or DQ6 (toggle) status bits or monitor the Ready/Busy# (RY/BY#) output to determine whether the operation is complete. To facilitate programming, an Unlock Bypass mode reduces command sequence overhead by requiring only two write cycles to program data instead of four. The VersatileI/O™ (VIO) control allows the host system to set the voltage levels that the device generates and tolerates on the CE# control input and DQ I/Os to the same voltage level that is asserted on the VIO pin. Refer to the Ordering Information section for valid VIO options. Hardware data protection measures include a low VCC detector that automatically inhibits write operations during power transitions. The hardware sector group protection feature disables both program and erase operations in any combination of sector groups of memory. This can be achieved in-system or via programming equipment. The Erase Suspend/Erase Resume feature allows the host system to pause an erase operation in a given sector to read or program any other sector and then complete the erase operation. The P rogram Suspend/Program Resume feature enables the host system to pause a program operation in a given sector to read any other sector and then complete the program operation. The hardware RESET# pin terminates any operation in progress and resets the device, after which it is then ready for a new operation. The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the device, enabling the host system to read boot-up firmware from the Flash memory device. The device reduces power consumption in the standby mode when it detects specific voltage levels on CE# and RESET#, or when addresses have been stable for a specified period of time. The Secured Silicon Sector provides a 128-word/256-byte area for code or data that can be permanently protected. Once this sector is protected, no further changes within the sector can occur. The Write Protect (WP#/ACC ) feature protects the first or last sector by asserting a logic low on the WP# pin. AMD MirrorBit flash technology combines years of Flash memory manufacturing experience to produce the highest levels of quality, reliability and cost effectiveness. The device electrically erases all bits within a sector simultaneously via hot-hole assisted erase. The data is programmed using hot electron injection.

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 Table 1. register serve as inputs to the internal state machine. The state machine outputs dictate the function of the device. Table 1 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.

Addresses are A22:A0 in word mode; A22:A-1 in byte mode. Sector addresses are A22:A15 in both modes. 2. The sector group protect and sector group unprotect functions may also be implemented via programming equipment. See the “Sector Group Protection and Unprotection” section. 3. If WP# = VIL, the first or last sector remains protected. If WP# = VIH, the first or last sector will be protected or unprotected as determined by the method described in “Write Protect (WP#)”. All sectors are unprotected when shipped from the factory (The Secured Silicon Sector may be factory protected depending on version ordered.) 4. DIN or DOUT as required by command sequence, data polling, or sector protect algorithm (see Figure 2). Word/Byte Configuration The BYTE# pin controls whether the device data I/O pins operate in the byte or word configuration. If the BYTE# pin is set at logic ‘1’, the device is in word configuration, DQ0–DQ15 are active and controlled by CE# and OE#. If the BYTE# pin is set at logic ‘0’, the device is in byte configuration, and only data I/O pins DQ0–DQ7 are active and controlled by CE# and OE#. The data I/O pins DQ8–DQ14 are tri-stated, and the DQ15 pin is used as an input for the LSB (A-1) address function. VersatileIO™ (VIO) Control The VersatileIO™ (VIO) control allows the host system to set the voltage levels that the device generates and tolerates on CE# and DQ I/Os to the same voltage level that is asserted on VIO. See “Ordering Information” for VIO options on this device. January 31, 2007 25270C7 Am29LV128MH/L 11 DATA SHEET tails 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. See the table in “DC Characteristics” on page 45 for the active current specification for the write mode. “AC Characteristics” on page 47 contains timing specification tables and timing diagrams for write operations. Write Buffer Write Buffer Programming allows the system write to a maximum of 16 words/32 bytes in one programming operation. This results in faster effective programming time than the standard programming algorithms. See “Write Buffer” for more information. Accelerated Program Operation The device offers accelerated program operations through the ACC function. This is one of two functions provided by the WP#/ACC pin. This function is primarily intended to allow faster manufacturing throughput at the factory. If the system asserts VHH on this pin, the device automatically enters the aforementioned Unlock Bypass mode, temporarily unprotects any protected sector groups, and uses the higher voltage on the pin to reduce the time required for program operations. The system would use a two-cycle program command sequence as required by the Unlock Bypass mode. Removing VHH from the WP#/ACC pin returns the device to normal operation. Note that the WP#/ACC pin must not be at V HH for operations other than accelerated programming, or device damage may result. WP# has an internal pullup; when unconnected, WP# is at VIH. 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 DQ7–DQ0. Standard read cycle timings apply in this mode. See “Autoselect Mode” on page 20 and “Autoselect Command Sequence” on page 29 for more information. Requirements for Reading Array Data To read array data from the outputs, the system must drive the CE# and OE# pins to VIL. CE# is the power control and selects the device. OE# is the output control and gates array data to the output pins. WE# should remain at VIH. The internal state machine is set for reading array data upon device power-up, or after a hardware reset. This ensures that no spurious alteration of the memory content occurs during the power transition. No command is necessary in this mode to obtain array data. Standard microprocessor read cycles that assert valid addresses on the device address inputs produce valid data on the device data outputs. The device remains enabled for read access until the command register contents are altered. See “Reading Array Data” for more information. See the table, See “Read-Only Operations” on page 47 for timing specifications and Figure 14 for the timing diagram. See the table in “DC Characteristics” on page 45 for the active current specification on reading array data. Page Mode Read The device is capable of fast page mode read and is compatible with the page mode Mask ROM read operation. This mode provides faster read access speed for random locations within a page. The page size of the device is 4 words/8 bytes. The appropriate page is selected by the higher address bits A(max)–A2. Address bits A1–A0 in word mode (A1–A-1 in byte mode) determine the specific word within a page. This is an asynchronous operation; the microprocessor supplies the specific word location. The random or initial page access is equal to tACC or tCE and subsequent page read accesses (as long as the locations specified by the microprocessor falls within that page) is equivalent to tPACC. When CE# is deasserted and reasserted for a subsequent access, the access time is t ACC o r t CE . Fast page mode accesses are obtained by keeping the “read-page addresses” constant and changing the “intra-read page” addresses. Writing Commands/Command Sequences To write a command or command sequence (which includes programming data to the device and erasing sectors of memory), the system must drive WE# and CE# to VIL, and OE# to VIH. The device features an Unlock Bypass mode to facilitate faster programming. Once the device enters the Unlock Bypass mode, only two write cycles are required to program a word or byte, instead of four. The “Word Program Command Sequence” section has de- 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# and RESET# pins are both held at VIO ± 0.3 V. (Note that this is a more restricted voltage range than 12 Am29LV128MH/L 25270C7 January 31, 2007 DATA VIH.) If CE# and RESET# are held at VIH, but not within VIO ± 0.3 V, the device will be in the standby mode, but the standby current will be greater. The device requires standard access time (t CE ) 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. See the table in “DC Characteristics” on page 45 for the standby current specification. SHEET SET# 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 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 (ICC4). 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. See the tables in “AC Characteristics” on page 47 for RESET# parameters and to Figure 16 for the timing diagram. 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#, 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. See the table in “DC Characteristics” on page 45 for the automatic sleep mode current specification. Output Disable Mode When the OE# input is at VIH, output from the device is disabled. The output pins are placed in the high impedance state. RESET#: Hardware Reset Pin The RESET# pin provides a hardware method of resetting the device to reading array data. When the RE- January 31, 2007 25270C7 Am29LV128MH/L 13 DATA Table 2.

Table 3 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 DQ7–DQ0. To access the autoselect codes in-system, the host system can issue the autoselect command via the command register, as shown in Table 10 and Table 11. This method does not require V ID. See “Autoselect Command Sequence” on page 29 for more information. Autoselect Mode The autoselect mode provides manufacturer and device identification, and sector group protection verification, through identifier codes output on DQ7–DQ0. This mode is primarily intended for programming equipment to automatically match a device to be programmed with its corresponding programming algorithm. However, the autoselect codes can also be accessed in-system through the command register. When using programming equipment, the autoselect mode requires VID on address pin A9. Address pins A6, A3, A2, A1, and A0 must be as shown in Table 3 In addition, when verifying sector protection, the sector Table 3.

The hardware sector group unprotection feature re-enables both program and erase operations in previously protected sector groups. Sector group protection/unprotection can be implemented via two methods. Sector group 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 25 shows the timing diagram. This method uses standard microprocessor bus cycle timing. For sector group unprotect, all unprotected sector group must first be protected prior to the first sector group unprotect write cycle. The device is shipped with all sector groups unprotected. AMD offers the option of programming and protecting sector groups 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 group is protected or unprotected. See “Autoselect Mode” on page 20 for details. Table 4.

Write Protect (WP#) The Write Protect function provides a hardware method of protecting the first or last sector group without using VID. Write Protect is one of two functions provided by the WP#/ACC input. If the system asserts VIL on the WP#/ACC pin, the device disables program and erase functions in the first or last sector group independently of whether those sector groups were protected or unprotected using the method described in “Sector Group Protection and Unprotection”. Note that if WP#/ACC is at VIL when the device is in the standby mode, the maximum input load current is increased. See the table in “DC Characteristics” on page 45 If the system asserts VIH on the WP#/ACC pin, the device reverts to whether the first or last sector was previously set to be protected or unprotected using the method described in “Sector Group Protection and Unprotection”. Note that WP# has an internal pullup; when unconnected, WP# is at VIH. START RESET# = VID (Note 1) Perform Erase or Program Operations RESET# = VIH Temporary Sector Group Unprotect Completed (Note 2) Temporary Sector Group Unprotect This feature allows temporary unprotection of previously protected sector groups to change data in-system. The Sector Group Unprotect mode is activated by setting the RESET# pin to VID. During this mode, formerly protected sector groups can be programmed or erased by selecting the sector group addresses. Once VID is removed from the RESET# pin, all the previously protected sector groups are protected again. Figure 1 Notes: 1. All protected sector groups unprotected (If WP# = VIL, the first or last sector will remain protected). 2. All previously protected sector groups are protected once again. Figure 1.

On power-up, or following a hardware reset, the device reverts to sending commands to sector SA0. Customer Lockable: Secured Silicon Sector NOT Programmed or Protected At the Factory Unless otherwise specified, the device is shipped such that the customer may program and protect the 256-byte Secured Silicon sector. Programming and protecting the Secured Silicon Sector must be used with caution since, once protected, there is no procedure available for unprotecting the Secured Silicon Sector area and none of the bits in the Secured Silicon Sector memory space can be modified in any way. The Secured Silicon Sector area can be protected using one of the following procedures: Write the three-cycle Enter Secured Silicon 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 Secured Silicon Sector without raising any device pin to a high voltage. Note that this method is only applicable to the Secured Silicon Sector. To verify the protect/unprotect status of the Secured Silicon Sector, follow the algorithm shown in Figure 3. Once the Secured Silicon Sector is programmed, locked and verified, the system must write the Exit Secured Silicon Sector Region command sequence to return to reading and writing within the remainder of the array. Factory Locked: Secured Silicon Sector Programmed and Protected At the Factory In devices with an ESN, the Secured Silicon Sector is protected when the device is shipped from the factory. The Secured Silicon Sector cannot be modified in any way. An ESN Factory Locked device has an 16-byte random ESN at addresses 000000h–000007h. Please contact your local AMD sales representative for details on ordering ESN Factory Locked devices. Customers may opt to have their code programmed by AMD through the AMD ExpressFlash service (Express Flash Factory Locked). The devices are then shipped from AMD’s factory with the Secured Silicon Sector permanently locked. Contact an AMD representative for details on using AMD’s ExpressFlash service. Secured Silicon Sector Flash Memory Region The Secured Silicon Sector feature provides a Flash memory region that enables permanent part identification through an Electronic Serial Number (ESN). The Secured Silicon Sector is 256 bytes in length, and uses a Secured Silicon Sector Indicator Bit (DQ7) to indicate whether or not the Secured Silicon 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 Secured Silicon Sector either customer lockable (standard shipping option) or factory locked (contact an AMD sales representative for ordering information). The customer-lockable version is shipped with the Secured Silicon Sector unprotected, allowing customers to program the sector after receiving the device. The customer-lockable version also has the Secured Silicon Sector Indicator Bit permanently set to a “0.” The factory-locked version is always protected when shipped from the factory, and has the Secured Silicon Sector Indicator Bit permanently set to a “1.” Thus, the Secured Silicon Sector Indicator Bit prevents customer-lockable devices from being used to replace devices that are factory locked. Note that the ACC function and unlock bypass modes are not available when the Secured Silicon Sector is enabled. The Secured Silicon sector address space in this device is allocated as follows: Table 5.

After the system has written the Enter Secured Silicon Sector command sequence, it may read the Secured Silicon Sector by using the addresses normally occupied by the first sector (SA0).

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 Remove VIH or VID from RESET# Write 40h to SecSi Sector address with A6 = 0, A1 = 1, A0 = 0 Read from SecSi Sector address with A6 = 0, A1 = 1, A0 = 0 Write reset command SecSi Sector Protect Verify complete 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# = VIL, CE# = VIH or WE# = VIH. To initiate a write cycle, CE# and WE# must be a logical zero while OE# is a logical one. Power-Up Write Inhibit If WE# = CE# = VIL and OE# = VIH during power up, the device does not accept commands on the rising edge of WE#. The internal state machine is automatically reset to the read mode on power-up. Figure 3. Secured Silicon Sector Protect Verify Hardware Data Protection The command sequence requirement of unlock cycles for programming or erasing provides data protection against inadver tent writes (refer to Table 10 and Table 11 for command definitions). In addition, the following hardware data protection measures prevent accidental erasure or programming, which might COMMON FLASH MEMORY INTERFACE (CFI) The Common Flash Interface (CFI) specification outlines device and host system software interrogation handshake, which allows specific vendor-specified software algorithms to be used for entire families of devices. Software support can then be device-independent, JEDEC ID-independent, and forward- and backward-compatible for the specified flash device families. Flash vendors can standardize their existing interfaces for long-term compatibility. This device enters the CFI Query mode when the system writes the CFI Query command, 98h, to address 55h, any time the device is ready to read array data. The system can read CFI information at the addresses given in Table 6, Table 7, Table 8, and Table 9. To terminate reading CFI data, the system must write the reset command. The system can also write the CFI query command when the device is in the autoselect mode. The device enters the CFI query mode, and the system can read CFI data at the addresses given in Table 6, Table 7, Table 8, and Table 9. The system must write the reset command to return the device to reading array data. For further information, please refer to the CFI Specification and CFI Publication 100, available via the World Wide Web at http://www.amd.com/flash/cfi.

Table 10 and Table 11 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#, whichever happens later. All data is latched on the rising edge of WE# or CE#, whichever happens first. See “AC Characteristics” on page 47 for timing diagrams. written while the device is in the Erase Suspend mode, writing the reset command returns the device to the erase-suspend-read mode. Once programming begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in an autoselect command sequence. Once in the autoselect mode, the reset command must be written to return to the read mode. If the device entered the autoselect mode while in the Erase Suspend mode, writing the reset command returns the device to the erase-suspend-read mode. If DQ5 goes high during a program or erase operation, writing the reset command returns the device to the read mode (or erase-suspend-read mode if the device was in Erase Suspend). Note that if DQ1 goes high during a Write Buffer Programming operation, the system must write the Write-to-Buffer-Abort Reset command sequence to reset the device for the next operation. 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 ready to read array data after completing an Embedded Program or Embedded Erase algorithm. After the device accepts an Erase Suspend command, the device enters the erase-suspend-read mode, after which the system can read data from any non-erase-suspended sector. After completing a programming operation in the Erase Suspend mode, the system may once again read array data with the same exception. See “Erase Suspend/Erase Resume Commands” on page 35 for more information. The system must issue the reset command to return the device to the read (or erase-suspend-read) mode if DQ5 goes high during an active program or erase operation, or if the device is in the autoselect mode. See the next section, “Reset Command,” for more information. See “Reading Array Data” on page 29 in the Device Bus Operations section for more information. “See the table, “Read-Only Operations” on page 47 for 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. Table 10 and Table 11 show the address and data requirements. This method is an alternative to that shown in Table 3, which is intended for PROM programmers and requires V ID on address pin A9. The autoselect command sequence may be written to an address 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. The autoselect command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle that contains the autoselect command. The device then enters the autoselect mode. The system may read at any address any number of times without initiating another autoselect command sequence: A read cycle at address XX00h returns the manufacturer code. Three read cycles at addresses 01h, 0Eh, and 0Fh return the device code. A read cycle to an address containing a sector address (SA), and the address 02h on A7–A0 in word mode returns 01h if the sector is protected, or 00h if it is unprotected. The system must write the reset command to return to the read mode (or erase-suspend-read mode if the device was previously in Erase Suspend). Reset Command Writing the reset command resets the device 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 device to the read mode. 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 the read mode. If the program command sequence is January 31, 2007 25270C7 Am29LV128MH/L 29 DATA SHEET data is still “0.” Only erase operations can convert a “0” to a “1.” Note: Single byte programming is not supported in x8-mode. Write buffer programming must be used during x8-mode operation. Enter Secured Silicon Sector/Exit Secured Silicon Sector Command Sequence The Secured Silicon Sector region provides a secured data area containing an 8-word/16-byte random Electronic Serial Number (ESN). The system can access the Secured Silicon Sector region by issuing the three-cycle Enter Secured Silicon Sector command sequence. The device continues to access the Secured Silicon Sector region until the system issues the four-cycle Exit Secured Silicon Sector command sequence. The Exit Secured Silicon Sector command sequence returns the device to normal operation. Table 10 and Table 11 show the address and data requirements for both command sequences. See also “Secured Silicon Sector Flash Memory Region” on page 24 for further information. Note: The write buffer, ACC function, and unlock bypass modes are not available when the Secured Silicon Sector is enabled. Unlock Bypass Command Sequence The unlock bypass feature allows the system to program words to the device faster than using the standard program command sequence. The unlock bypass command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle containing the unlock bypass command, 20h. The device then enters the unlock bypass mode. A two-cycle unlock bypass program command sequence is all that is required to program in this mode. The first cycle in this sequence contains the unlock bypass program command, A0h; the second cycle contains the program address and data. Additional data is programmed in the same manner. This mode dispenses with the initial two unlock cycles required in the standard program command sequence, resulting in faster total programming time. Table 10 and Table 11 show 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. The first cycle must contain the data 90h. The second cycle must contain the data 00h. The device then returns to the read mode. Write Buffer Programming Write Buffer Programming allows the system write to a maximum of 16 words/32 bytes in one programming operation. This results in faster effective programming time than the standard programming algorithms. The Write Buffer Programming command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle containing the Write Buffer Load command written at the Sector Address in which programming will occur. The fourth cycle writes the sector address and the number of word locations, minus one, to be programmed. For example, if the system will program 6 unique address locations, then 05h should be written to the device. This tells the device how many write buffer addresses will be loaded with data and therefore when to expect the Program Buffer to Flash command. The number of locations to program cannot exceed the size of the write buffer or the operation will abort. The fifth cycle writes the first address location and data to be programmed. The write-buffer-page is selected by address bits AMAX–A 4. All subsequent add r e s s / d a t a p a i r s m u s t fa l l w i t h i n t h e selected-write-buffer-page. The system then writes the Word 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 10 and Table 11 show the address and data requirements for the word program command sequence. When the Embedded Program algorithm is complete, the device 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 or DQ6. See “Wr ite Operation Status” on page 39 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 the device has returned to the read mode, to ensure data integrity. Note that the Secured Silicon Sector, autoselect, and CFI functions are unavailable when a program operation is in progress. Programming is allowed in any sequence and across sector boundaries.

However, a succeeding read will show that the 30 Am29LV128MH/L 25270C7 January 31, 2007 DATA remaining address/data pairs into the write buffer. Write buffer locations may be loaded in any order. The write-buffer-page address must be the same for all address/data pairs loaded into the write buffer. (This means Write Buffer Programming cannot be performed across multiple write-buffer pages. This also means that Write Buffer Programming cannot be performed across multiple sectors. If the system attempts to load programming data outside of the selected write-buffer page, the operation will abort. Note that if a Write Buffer address location is loaded multiple times, the address/data pair counter will be decremented for every data load operation. The host s y s t e m mu s t t h e r e fo r e a c c o u n t fo r l o a d i n g a write-buffer location more than once. The counter decrements for each data load operation, not for each unique write-buffer-address location. Note also that if an address location is loaded more than once into the buffer, the final data loaded for that address will be programmed. Once the specified number of write buffer locations have been loaded, the system must then write the Program Buffer to Flash command at the sector address. Any other address and data combination aborts the Write Buffer Programming operation. The device then begins programming. Data polling should be used while monitoring the last address location loaded into the write buffer. DQ7, DQ6, DQ5, and DQ1 should be monitored to determine the device status during Write Buffer Programming. The write-buffer programming operation can be suspended using the standard program suspend/resume commands. Upon successful completion of the Write Buffer Programming operation, the device is ready to execute the next command. The Write Buffer Programming Sequence can be aborted in the following ways: SHEET Load a value that is greater than the page buffer size during the Number of Locations to Program step. Write to an address in a sector different than the one specified during the Write-Buffer-Load command. Write an Address/Data pair to a different write-buffer-page than the one selected by the Starting Address during the write buffer data loading stage of the operation. Write data other than the Confirm Command after the specified number of data load cycles. The abort condition is indicated by DQ1 = 1, DQ7 = DATA# (for the last address location loaded), DQ6 = toggle, and DQ5=0. A Write-to-Buffer-Abort Reset command sequence must be written to reset the device for the next operation. Note that the full 3-cycle Write-to-Buffer-Abort Reset command sequence is required when using Write-Buffer-Programming features in Unlock Bypass mode. Accelerated Program The device offers accelerated program operations through the WP#/ACC pin. When the system asserts VHH on the WP#/ACC pin, the device automatically enters the Unlock Bypass mode. The system may then write the two-cycle Unlock Bypass program command sequence. The device uses the higher voltage on the WP#/ACC pin to accelerate the operation. Note that the WP#/ACC pin must not be at VHH for operations other than accelerated programming, or device damage may result. WP# has an internal pullup; when unconnected, WP# is at VIH. Figure 5 illustrates the algorithm for the program operation. Refer to the Erase and Program Operations table in the AC Characteristics section for parameters, and Figure 18 for timing diagrams.

When the Program Suspend command is written during a programming process, the device halts the program operation within 15 μs maximum (5 μs typical) and updates the status bits. Addresses are not required when writing the Program Suspend command. After the programming operation has been suspended, the system can read array data from any non-suspended sector. The Program Suspend command may also be issued during a programming operation while an erase is suspended. In this case, data may be read from any addresses not in Erase Suspend or Program Suspend. If a read is needed from the Secured Silicon Sector area (One-time Program area), then user must use the proper command sequences to enter and exit this region. The system may also write the autoselect command sequence when the device is in the Program Suspend mode. The system can read as many autoselect codes as required. When the device exits the autoselect mode, the device reverts to the Program Suspend mode, and is ready for another valid operation. See Autoselect Command Sequence for more information. After the Program Resume command is written, the device reverts to programming. The system can determine the status of the program operation using the DQ7 or DQ6 status bits, just as in the standard program operation. See “Write Operation Status” on page 39 for more information. The system must write the Program Resume command to exit the Program Suspend mode and continue the programming operation. Further writes of the Resume command are ignored. Another Program Suspend command can be written after the device has resume programming. Verify Data? No Yes No Increment Address Last Address? Yes Programming Completed Note: See Table 10 and Table 11 for program command sequence. Figure 5.

The system can determine the status of the erase operation by using DQ7, DQ6, or DQ2. See “Write Operation Status” on page 39 for information on these status bits. Any commands written during the chip erase operation are ignored.However, note that a hardware reset immediately terminates the erase operation. If that occurs, the chip erase command sequence should be reinitiated once the device has returned to reading array data, to ensure data integrity. Note that the Secured Silicon Sector, autoselect, and CFI functions are unavailable when an program operation is in progress. Figure 6 illustrates the algorithm for the erase operation. Refer to the Erase and Program Operations tables in the AC Characteristics section for parameters, and Figure 20 section for timing diagrams. Program Operation or Write-to-Buffer Sequence in Progress Write address/data XXXh/B0h Write Program Suspend Command Sequence Command is also valid for Erase-suspended-program operations Wait 15 μs Read data as required Autoselect and SecSi Sector read operations are also allowed Data cannot be read from erase- or program-suspended sectors No Done reading? Yes Write address/data XXXh/30h Write Program Resume Command Sequence 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 9 and Table 10 show the address and data requirements for the sector erase command sequence. The device does not require the system to preprogram prior to erase. The Embedded Erase algorithm automatically programs and verifies the entire memory for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or timings during these operations. After the command sequence is written, a sector erase time-out of 50 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 50 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 the device to the read mode. The system must rewrite the command sequence and any additional addresses and commands. Note that the Secured Silicon Sector, autoselect, and CFI functions are unavailable when an erase operation is in progress. Device reverts to operation prior to Program Suspend Figure 6. Program Suspend/Program Resume 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 10 and Table 11 show the address and data requirements for the chip erase command sequence. 34 Am29LV128MH/L 25270C7 January 31, 2007 DATA 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 device returns to reading array data and addresses are no longer latched. The system can determine the status of the erase operation by reading DQ7, DQ6, or DQ2 in the erasing sector. See “Write Operation Status” on page 39 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 the device has returned to reading array data, to ensure data integrity. Figure 6 illustrates the algorithm for the erase operation. Refer to the Erase and Program Operations tables in the AC Characteristics section for parameters, and Figure 20 section for timing diagrams. SHEET After the erase operation has been suspended, the device 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. See “Write Operation Status” on page 39 for information on these status bits. After an erase-suspended program operation is complete, the device 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 word program operation. See “Write Operation Status” on page 39 for more information. In the erase-suspend-read mode, the system can also issue the autoselect command sequence. Refer to the Autoselect Mode and Autoselect Command Sequence sections for details. To resume the sector erase operation, the system must write the Erase Resume command. Further writes of the Resume command are ignored. Another Erase Suspend command can be written after the chip has resumed erasing. Note: During an erase operation, this flash device performs multiple internal operations which are invisible to the system. When an erase operation is suspended, any of the internal operations that were not fully completed must be restarted. As such, if this flash device is continually issued suspend/resume commands in rapid succession, erase progress will be impeded as a function of the number of suspends. The result will be a longer cumulative erase time than without suspends. Note that the additional suspends do not affect device reliability or future performance. In most systems rapid erase/suspend activity occurs only briefly. In such cases, erase performance will not be significantly impacted. Erase Suspend/Erase Resume Commands The Erase Suspend command, B0h, allows the system to interrupt a sector erase operation and then read data from, or program data to, any sector not selected for erasure. This command is valid only during the sector erase operation, including the 50 µs time-out period during the sector erase command sequence. The Erase Suspend command is ignored if written during the chip erase operation or Embedded Program algorithm. When the Erase Suspend command is written during the sector erase operation, the device requires a typical of 5 µs (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.

Table 12 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. valid data, the data outputs on DQ0–DQ6 may be still invalid. Valid data on DQ0–DQ7 will appear on successive read cycles. Table 12 shows the outputs for Data# Polling on DQ7. Figure 8 shows the Data# Polling algorithm. Figure 21 in the 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 the device 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 the device 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 device 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 device 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. Just prior to the completion of an Embedded Program or Erase operation, DQ7 may change asynchronously with DQ0–DQ6 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 completed the program or erase operation and DQ7 has START 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 8. Data# Polling Algorithm January 31, 2007 25270C7 Am29LV128MH/L 39 DATA SHEET 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 “DQ7: Data# Polling” on page 39. 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. DQ6 also toggles during the erase-suspend-program mode, and stops toggling once the Embedded Program algorithm is complete. Table 12 shows the outputs for Toggle Bit I on DQ6. Figure 9 shows the toggle bit algorithm. Figure 22 in the “AC Characteristics” section shows the toggle bit timing diagrams. Figure 23 shows the differences between DQ2 and DQ6 in graphical form. See “DQ2: Toggle Bit II” on page 41. 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 in the erase-suspend-read mode. Table 12 shows the outputs for RY/BY#. 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# to control the read cycles. When the operation is complete, DQ6 stops toggling. 40 Am29LV128MH/L 25270C7 January 31, 2007 DATA SHEET DQ2: Toggle Bit II START Read DQ7–DQ0 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# 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 12 to compare outputs for DQ2 and DQ6. Figure 9 shows the toggle bit algorithm in flowchart form, and “DQ2: Toggle Bit II” explains the algorithm. See also the “RY/BY#: Ready/Busy#” subsection. Figure 22 shows the toggle bit timing diagram. Figure 23 shows the differences between DQ2 and DQ6 in graphical form. Read DQ7–DQ0 Toggle Bit = Toggle? Yes No No DQ5 = 1? Yes Read DQ7–DQ0 Twice Reading Toggle Bits DQ6/DQ2 Refer to Figure 9 for the following discussion. Whenever the system initially begins reading toggle bit status, it must read DQ7–DQ0 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 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 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 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 Toggle Bit = Toggle? No Yes Program/Erase Operation Not Complete, Write Reset Command Program/Erase Operation Complete Note: T he 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 9. Toggle Bit Algorithm January 31, 2007 25270C7 Am29LV128MH/L 41 DATA 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 9). SHEET mand. 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 “Sector Erase Command Sequence” on page 34. 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 12 shows the status of DQ3 relative to the other status bits. DQ5: Exceeded Timing Limits DQ5 indicates whether the program, erase, or write-to-buffer 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.” In all these cases, the system must write the reset command to return the device to the reading the array (or to erase-suspend-read if the device 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 com- DQ1: Write-to-Buffer Abort DQ1 indicates whether a Write-to-Buffer operation was aborted. Under these conditions DQ1 produces a “1”. The system must issue the Write-to-Buffer-Abort-Reset command sequence to return the device to reading array data. See “Write Buffer Programming” on page 30 for more details. 42 Am29LV128MH/L 25270C7 January 31, 2007 DATA Table 12.
