Publication# 26009 Rev: C Amendment/0 Issue Date: April 7, 2003 P E N D I N G GENERAL DESCRIPTION The Am29LV017M is a 16 Mbit, 3.0 Volt-only Flash memory organized as 2,097,152 bytes. The device is offered in 48-ball FBGA and 40-pin TSOP packages. The byte-wide (x8) data appears on DQ7–DQ0. All read, program, and erase operations are accomplished using only a single power supply. The device can also be programmed in standard EPROM programmers. The standard device offers access times of 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 3.0 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 controls 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 automatically times the program pulse widths and verifies proper cell margin. The Unlock Bypass mode facilitates faster programming times by requiring only two write cycles to program data instead of four. Device erasure occurs by executing the erase command 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# 2 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 operations during power transitions. The hardware sector protection feature disables both program and erase operations in any combination of the sectors of memory. This can be achieved in-system or via programming equipment. The 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. The Program 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 internal state machine to reading array data. The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the device, enabling the system microprocessor to read the boot-up firmware from the Flash memory. The device offers two power-saving features. When addresses have been stable for a specified amount of time, the device enters the automatic sleep mode. The system can also place the device into the standby mode. Power consumption is greatly reduced in both these modes. AMD’s 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 Fowler-Nordheim tunneling. The data is programmed using hot electron injection.

Am29LV017M April 7, 2003 P E N D I N G DEVICE BUS OPERATIONS 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. 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 Table 1.

See the “Sector Protection/Unprotection” section. Requirements for Reading Array Data Writing Commands/Command Sequences 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. 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 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. Refer to the AC Read Operations table for timing specifications and to Figure 13 for the timing diagram. ICC1 in the DC Characteristics table represents the active current specification for reading array data. April 7, 2003 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 byte, instead of four. The “Byte Program Command Sequence” section has details on programming data to the device using both standard and Unlock Bypass command sequences. An erase operation can erase one sector, multiple sectors, or the entire device. Table 2 indicates the address space that each sector occupies. A “sector address” consists of the address bits required to uniquely select a sector. The “Word/Byte Program Command Sequence” section has details on erasing a sector or the entire chip, or suspending/resuming the erase operation. After the system writes the autoselect command sequence, the device enters the autoselect mode. The system can then read autoselect codes from the inter- Am29LV017M 9 P E N D I N G 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 active 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 ICC read specifications apply. Refer to “Write Operation Status” for more information, and to “AC Characteristics” 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 CE# and RESET# pins are both held at VCC ± 0.3 V. (Note that this is a more restricted voltage range than VIH.) If CE# and RESET# are held at VIH, but not within VCC ± 0.3 V, the device will be in the standby mode, but the standby current will be greater. The device requires standard access time (tCE) for read access when the device is in either of these standby modes, before it is ready to read data. The device also enters the standby mode when the RESET# pin is driven low. Refer to the next section, “RESET#: Hardware Reset Pin”. If the device is deselected during erasure or programming, the device draws active current until the operation is completed. ICC3 in the DC Characteristics table represents the standby current specification. Automatic Sleep Mode The automatic sleep mode minimizes Flash device energy consumption. The device automatically enables this mode when addresses remain stable for tACC + 30 ns. The automatic sleep mode is 10 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. I CC4 in the DC Characteristics table represents the automatic sleep m ode cu rrent specification. RESET#: Hardware Reset Pin The RESET# pin provides a hardware method of resetting the device to reading array data. When the RESET# pin is driven low for at least a period of tRP, the device immediately terminates any operation in progress, tristates all output pins, and ignores all read/write commands for the duration of the RESET# pulse. The device also resets the internal state machine to reading array data. The operation that was interrupted should be reinitiated once the device is 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. If RESET# is asserted during a program or erase operation, the RY/BY# pin remains a “0” (busy) until the internal reset operation is complete, which requires a time of tREADY (during Embedded Algorithms). The system can thus monitor RY/BY# to determine whether the reset operation is complete. If RESET# is asserted when a program or erase operation is not executing (RY/BY# pin is “1”), the reset operation is completed within a time of tREADY (not during Embedded Algorithms). The system can read data tRH after the RESET# pin returns to VIH. Refer to the AC Characteristics tables for RESET# parameters and to Figure 14 for the 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 impedance state. Am29LV017M April 7, 2003 P E N D I N G Table 2.

In addition, when verifying sector protection, the sector address must appear on the appropriate highest order address bits (see 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. The autoselect mode provides manufacturer and device identification, and sector 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. To access the autoselect codes in-system, the host system can issue the autoselect command via the command register, as shown in Table 8. This method does not require VID. See “” for details on using the autoselect mode. When using programming equipment, the autoselect mode requires VID (11.5 V to 12.5 V) on address pin A9. Address pins A6, A1, and A0 must be as shown in Table 3.

The hardware sector unprotection feature re-enables both program and erase operations in previously protected sectors. protected again. Figure 1 shows the algorithm, and Figure 20 shows the timing diagrams, for this feature. START Sector protection/unprotection requires VID on the RESET# pin only, and can be implemented either in-system or via programming equipment. Figure 2 shows the algorithms and Figure 21 shows the timing diagram. This method uses standard microprocessor bus cycle timing. For sector unprotect, all unprotected sectors must first be protected prior to the first sector unprotect write cycle. RESET# = VID (Note 1) Perform Erase or Program Operations RESET# = VIH The device is shipped with all sectors unprotected. AMD offers the option of programming and protecting sectors at its factory prior to shipping the device through AMD’s ExpressFlash™ Service. Contact an AMD representative for details. Temporary Sector Unprotect Completed (Note 2) It is possible to determine whether a sector is protected or unprotected. See “Autoselect Mode” for details. Notes: Temporary Sector Unprotect 1. All protected sectors unprotected. This feature allows temporary unprotection of previously protected sectors to change data in-system. The Sector Unprotect mode is activated by setting the RESET# pin to VID. During this mode, formerly protected sectors can be programmed or erased by selecting the sector addresses. Once VID is removed from the RESET# pin, all the previously protected sectors are April 7, 2003 2. All previously protected sectors are protected once again. Figure 1.

The SecSi Sector is 128 words/256 bytes in length, and uses a SecSi Sector Indicator Bit (DQ7) to indicate whether or not the SecSi Sector is locked when shipped from the factory. This bit is permanently set at the factory and cannot be changed, which prevents cloning of a factory locked part. This ensures the security of the ESN once the product is shipped to the field. In devices with an ESN, the SecSi Sector is protected when the device is shipped from the factory. The SecSi Sector cannot be modified in any way. A factory locked device has an 8-word/16-byte random ESN at addresses 000000h–000007h. AMD offers the device with the SecSi Sector either factory locked or customer lockable. The factorylocked version is always protected when shipped from the factory, and has the SecSi (Secured Silicon) Sector Indicator Bit permanently set to a “1.” The customer-lockable version is shipped with the SecSi Sector unprotected, allowing customers to program the sector after receiving the device. The customerlockable version also has the SecSi Sector Indicator Bit permanently set to a “0.” Thus, the SecSi Sector Indicator Bit prevents customer-lockable devices from being used to replace devices that are factory locked. The SecSi sector address space in this device is allocated as follows: Table 1. SecSi Sector Address Range x16 x8 000000h– 000007h 000000h– 00000Fh 000008h– 00007Fh 000010h– 0000FFh SecSi Sector Contents Standard Factory Locked ExpressFlash Factory Locked ESN ESN or determined by customer Unavailable Determined by customer Customer Lockable: SecSi Sector NOT Programmed or Protected At the Factory As an alternative to the factory-locked version, the device may be ordered such that the customer may program and protect the 128-word/256 bytes SecSi sector. The system may program the SecSi Sector using the write-buffer, accelerated and/or unlock bypass methods, in addition to the standard programming command sequence. See Command Definitions. Programming and protecting the SecSi Sector must be used with caution since, once protected, there is no procedure available for unprotecting the SecSi Sector area and none of the bits in the SecSi Sector memory space can be modified in any way. Customer Lockable The SecSi Sector area can be protected using one of the following procedures: Determined by customer ■ Write the three-cycle Enter SecSi Sector Region command sequence, and then follow the in-system sector protect algorithm as shown in Figure 1, except that RESET# may be at either VIH or VID. This allows in-system protection of the SecSi Sector without raising any device pin to a high voltage. Note that this method is only applicable to the SecSi Sector. The system accesses the SecSi Sector through a command sequence (see “Enter SecSi Sector/Exit SecSi Sector Command Sequence”). After the system has written the Enter SecSi Sector command sequence, it may read the SecSi Sector by using the addresses normally occupied by the first sector (SA0). This mode of operation continues until the system issues the Exit SecSi Sector command sequence, or until power is removed from the device. On power-up, or following a hardware reset, the device reverts to sending commands to sector SA0. Note that the ACC function and unlock bypass modes are not available when the SecSi Sector is enabled. April 7, 2003 Customers may opt to have their code programmed by AMD through the AMD ExpressFlash service. The devices are then shipped from AMD’s factory with the SecSi Sector permanently locked. Contact an AMD representative for details on using AMD’s ExpressFlash service. ■ To verify the protect/unprotect status of the SecSi Sector, follow the algorithm shown in Figure 2. Once the SecSi Sector is programmed, locked and verified, the system must write the Exit SecSi Sector Region command sequence to return to reading and writing within the remainder of the array. Am29LV017M 15 P E N D I N G mand definitions). In addition, the following hardware data protection measures prevent accidental erasure or programming, which might otherwise be caused by spurious system level signals during VCC power-up and power-down transitions, or from system noise. START RESET# = VIH or VID Wait 1 µs Write 60h to any address 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 If data = 00h, SecSi Sector is unprotected. If data = 01h, SecSi Sector is protected. 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. 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. Remove VIH or VID from RESET# Write reset command Write Pulse “Glitch” Protection Noise pulses of less than 5 ns (typical) on OE#, CE# or WE# do not initiate a write cycle. SecSi Sector Protect Verify complete 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 Figure 3.

Am29LV017M April 7, 2003 P E N D I N G 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 Table 4. data. The system can read CFI information at the addresses given in Tables 4–7. To terminate reading CFI data, the system must write the reset command. The system can also write the CFI query command when the device is in the autoselect mode. The device enters the CFI query mode, and the system can read CFI data at the addresses given in Tables 4–7. The system must write the reset command to return the device to reading array data.

Table 8 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. 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. After the device accepts an Erase Suspend command, the device enters the Erase Suspend mode. The system can read array data using the standard read timings, except that if it reads at an address within erasesuspended 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 Suspend/Erase Resume Commands” for more information on this mode. The system must issue the reset command to re-enable the device for reading array data if DQ5 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 Figure 13 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 (also applies to programming in Erase Suspend mode). Once programming begins, 20 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 (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 reading array data (also applies during Erase Suspend). 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. Table 8 shows the address and data requirements. This method is an alternative to that shown in Table 3, which is intended for PROM programmers and requires VID 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 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 XX02h returns XX01h if that sector is protected, or 00h if it is unprotected. Refer to Table 2 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 The device programs one byte of data for each program operation. The command sequence requires four bus cycles, and 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 generates the program pulses and verifies the programmed cell margin. Table 8 shows the address and data requirements for the byte program command sequence. Note that the autoselect and CFI functions are unavailable when a program operation is in progress. 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 DQ7, DQ6, or RY/BY#. See “Write Operation Status” for information on these status bits. Am29LV017M April 7, 2003 P E N D I N G Any commands written to the device during the Embedded Program Algorithm are ignored. Note that a hardware reset immediately terminates the programming operation. The Byte Program command sequence should be reinitiated once the device has reset to reading array data, to ensure data integrity. don’t cares for both cycles. The device then returns to reading array data. Figure 4 illustrates the algorithm for the program operation. See the Erase/Program Operations table in “AC Characteristics” for parameters, and to Figure 15 for timing diagrams 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 DQ5 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”. START Write Program Command Sequence Unlock Bypass Command Sequence The unlock bypass feature allows the system to program bytes 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 8 shows the requirements for the command sequence. During the unlock bypass mode, only the Unlock Bypass Program and Unlock Bypass Reset commands are valid. To exit the unlock bypass mode, the system must issue the two-cycle unlock bypass reset command sequence. The first cycle must contain the data 90h; the second cycle the data 00h. Addresses are Embedded Program algorithm in progress Verify Data? No Yes Increment Address No Last Address? Yes Programming Completed Note: See Table 8 for program command sequence. Figure 4. April 7, 2003 Data Poll from System Am29LV017M Program Operation 21 P E N D I N G Program Suspend/Program Resume Command Sequence The Program Suspend command allows the system to interrupt a programming operation or a Write to Buffer programming operation so that data can be read from any non-suspended sector. When the Program Suspend command is written during a programming process, the device halts the program operation within 15 µs maximum (5µs typical) and updates the status bits. Addresses are not required when writing the Program Suspend command. The system must write the Program Resume command (address bits are don’t care) 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. Program Operation or Write-to-Buffer Sequence in Progress After the programming operation has been suspended, the system can read array data from any nonsuspended 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 SecSi 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 for more information. 22 Write address/data XXXh/B0B0h Write Program Suspend Command Sequence Command is also valid for Erase-suspended-program operations Wait 15 µs Read data as required No Autoselect and SecSi Sector read operations are also allowed Data cannot be read from erase- or program-suspended sectors Done reading?

Program Suspend/Program Resume Am29LV017M April 7, 2003 P E N D I N G 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 8 shows the address and data requirements for the chip erase command sequence. Note that the autoselect, and CFI functions are unavailable when a erase operation is in progress. Any commands written to the chip during the Embedded Erase algorithm are ignored. Note that a hardware reset during the chip erase operation immediately terminates the operation. The Chip Erase command sequence 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 6 illustrates the algorithm for the erase operation. See the Erase/Program Operations tables in “AC Characteristics” for parameters, and to Figure 16 for timing diagrams. 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 write cycles are then followed by the address of the sector to be erased, and the sector erase command. Table 8 shows the address and data requirements for the sector erase command sequence. Note that the autoselect and CFI functions are unavailable when a erase operation is in progress. The device does not require the system to preprogram the memory prior to erase. The Embedded Erase algorithm 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 timings 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 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 beApril 7, 2003 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 operation. 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 status of the erase operation by using DQ7, DQ6, DQ2, or RY/BY#. (Refer to “Write Operation Status” for information on these status bits.) Figure 6 illustrates the algorithm for the erase operation. Refer to the Erase/Program Operations tables in the “AC Characteristics” section for parameters, and to Figure 16 for timing diagrams. Erase Suspend/Erase Resume Commands The Erase Suspend command 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 time-out period 50 µs during the sector erase command sequence. The Erase Suspend command is ignored if written during the chip erase operation or Embedded Program algorithm. Writing the Erase Suspend command during the Sector Erase time-out immediately terminates the time-out period and suspends the erase operation. Addresses are “don’t-cares” when writing the Erase Suspend 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- Am29LV017M 23 P E N D I N G minates the time-out period and suspends the erase operation. Erase Suspend command can be written after the device has resumed erasing. 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 sectors produces status data 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. START Write Erase Command Sequence Data Poll from System After an erase-suspended program operation is complete, 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 DQ6 status bits, just as in the standard program operation. See “Write Operation Status” for more information. The system may also write the autoselect command sequence when the device is in the Erase Suspend mode. The device allows reading autoselect codes even at addresses within erasing sectors, since the codes are not stored in the memory array. When the device exits the autoselect mode, the device reverts to the Erase Suspend mode, and is ready for another valid operation. See “Autoselect Command Sequence” for more information. The system must write the Erase Resume command (address bits are “don’t care”) to exit the erase suspend mode and continue the sector erase operation. Further writes of the Resume command are ignored. Another 24 No Embedded Erase algorithm in progress Data = FFh? Yes Erasure Completed Notes: 1. See Table 8 for erase command sequence. 2.

Command is valid when device is ready to read array data or when device is in autoselect mode. 4. Address bits are don’t care for unlock and command cycles, except when PA or SA is required. 10. The Unlock Bypass command is required prior to the Unlock Bypass Program command. 5. No unlock or command cycles required when device is in read mode. 11. The Unlock Bypass Reset command is required to return to reading array data when the device is in the Unlock Bypass mode. 6. The Reset command is required to return to the read mode when the device is in the autoselect mode or if DQ5 goes high. 7. The fourth cycle of the autoselect command sequence is a read cycle.

The Erase Suspend command is valid only during a sector erase operation. 13. The Erase Resume command is valid only during the Erase Suspend mode. Am29LV017M 25 P E N D I N G WRITE OPERATION STATUS The device provides several bits to determine the status of a write operation: DQ2, DQ3, DQ5, DQ6, DQ7, and RY/BY#. Table 9 and the following subsections describe the functions of these bits. DQ7, RY/BY#, and DQ6 each offer a method for determining whether a program or erase operation is complete or in progress. These three bits are discussed first. Table 9 shows the outputs for Data# Polling on DQ7. Figure 7 shows the Data# Polling algorithm. START DQ7: Data# Polling Read DQ7–DQ0 Addr = VA The Data# Polling bit, DQ7, indicates to the host system whether an Embedded Algorithm is in progress or completed, or whether the device is in Erase Suspend. Data# Polling is valid after the rising edge of the final WE# pulse in the program or erase command sequence. During the Embedded Program algorithm, the device outputs on 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 reading array data. DQ7 = Data? No No When the system detects DQ7 has changed from the complement to true data, it can read valid data at DQ7– DQ0 on the following read cycles. This is because DQ7 may change asynchronously with DQ0–DQ6 while Output Enable (OE#) is asserted low. Figure 17, Data# Polling Timings (During Embedded Algorithms), in the “AC Characteristics” section illustrates this. 26 DQ5 = 1? Yes Read DQ7–DQ0 Addr = VA 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. 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 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 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. Yes DQ7 = Data? Yes No FAIL PASS Notes: 1. VA = Valid address for programming. During a sector erase operation, a valid address is an address within any sector selected for erasure. During chip erase, a valid address is any non-protected sector address. 2. DQ7 should be rechecked even if DQ5 = “1” because DQ7 may change simultaneously with DQ5. Am29LV017M Figure 7. Data# Polling Algorithm April 7, 2003 P E N D I N G RY/BY#: Ready/Busy# The RY/BY# is a dedicated, open-drain output pin that indicates whether an Embedded Algorithm is in progress or complete. The RY/BY# status is valid after the rising edge of the final WE# pulse in the command sequence. Since RY/BY# is an open-drain output, several RY/BY# pins can be tied together in parallel with a pull-up resistor to VCC. (The RY/BY# pin is not available on the 44-pin SO package.) 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 9 shows the outputs for RY/BY#. Figures 14, 15 and 16 shows RY/BY# for reset, program, and erase operations, respectively. 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. 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 erasesuspended. When the device is actively erasing (that is, the Embedded Erase algorithm is in progress), DQ6 toggles. When the device enters the Erase Suspend mode, DQ6 stops toggling. However, the system must also use DQ2 to determine which sectors are erasing or erase-suspended. Alternatively, the system can use DQ7 (see the subsection on DQ7: Data# Polling). If a program address falls within a protected sector, DQ6 toggles for approximately 1 µs after the program command sequence is written, then returns to reading array data. DQ6 also toggles during the erase-suspend-program mode, and stops toggling once the Embedded Program algorithm is complete. April 7, 2003 Table 9 shows the outputs for Toggle Bit I on DQ6. Figure 8 shows the toggle bit algorithm in flowchart form, and the section “Reading Toggle Bits DQ6/DQ2” explains the algorithm. Figure 18 in the “AC Characteristics” section shows the toggle bit timing diagrams. Figure 19 shows the differences between 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, 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 9 to compare outputs for DQ2 and DQ6. Figure 8 shows the toggle bit algorithm in flowchart form, and the section “Reading Toggle Bits DQ6/DQ2” explains the algorithm. See also the DQ6: Toggle Bit I subsection. Figure 18 shows the toggle bit timing diagram. Figure 19 shows the differences between DQ2 and DQ6 in graphical form. Reading Toggle Bits DQ6/DQ2 Refer to Figure 8 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 Am29LV017M 27 P E N D I N G must write the reset command to return to reading array data. START 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 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 8). Read DQ7–DQ0 1) Read DQ7–DQ0 Table 9 shows the outputs for Toggle Bit I on DQ6. Figure 8 shows the toggle bit algorithm. Figure 18 in the “AC Characteristics” section shows the toggle bit timing diagrams. Figure 19 shows the differences between DQ2 and DQ6 in graphical form. See also the subsection on DQ2: Toggle Bit II. Toggle Bit = Toggle? No Yes No DQ5 = 1? Yes Read DQ7–DQ0 Twice (Notes 1, 2) Toggle Bit = Toggle? No Yes Program/Erase Operation Not Complete, Write Reset Command Program/Erase Operation Complete 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 DQ5 changes to “1”. See text. Figure 8. 28 Am29LV017M Toggle Bit Algorithm April 7, 2003 P E N D I N G DQ5: Exceeded Timing Limits DQ5 indicates whether the program or erase time has exceeded a specified internal pulse count limit. Under these conditions DQ5 produces a “1.” This is a failure condition that indicates the program or erase cycle was not successfully completed. The DQ5 failure condition may appear if the system tries to program a “1” to a location that is previously programmed to “0.” Only an erase operation can change a “0” back to a “1.” Under this condition, the device halts the operation, and when the operation has exceeded the timing limits, DQ5 produces a “1.” Under both these conditions, the system must issue the reset command to return the device to reading array data. DQ3: Sector Erase Timer After writing a sector erase command sequence, the system may read DQ3 to determine whether or not an erase operation has begun. (The sector erase timer does not apply to the chip erase command.) If addi- Table 9. Operation Embedded Program Standard Algorithm Mode Embedded Erase Algorithm Program Suspend Mode ProgramSuspend Read Reading within Erase Suspended Sector Erase Suspend Reading within Non-Erase Mode Suspended Sector Erase-Suspend-Program tional sectors are selected for erasure, the entire timeout also applies after each additional sector erase command. When the time-out is complete, DQ3 switches from “0” to “1.” If the time between additional sector erase commands from the system can be assumed to be less than 50 µs, the system need not monitor DQ3. See also the “Sector Erase Command Sequence” section. After the sector erase command sequence is written, the system should read the status on DQ7 (Data# Polling) or DQ6 (Toggle Bit I) to ensure the device has accepted the command sequence, and then read DQ3. If DQ3 is “1”, the internally controlled erase cycle has begun; all further commands (other than 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 9 shows the outputs for DQ3.

DQ5 switches to ‘1’ when an Embedded Program or Embedded Erase operation has exceeded the maximum timing limits. See “DQ5: Exceeded Timing Limits” for more information. 2. DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate subsection for further details.
