Publication Number S29GL-P_00 Revision A Amendment 7 Issue Date November 8, 2007 Data Sheet (Pre limin ar y) Notice On Data Sheet Designations Spansion Inc. issues data sheets with Advance Information or Preliminary designations to advise readers of product information or intended specifications throughout the product life cycle, including development, qualification, initial production, and full production. In all cases, however, readers are encouraged to verify that they have the latest information before finalizing their design. The following descriptions of Spansion data sheet designations are presented here to highlight their presence and definitions. Advance Information The Advance Information designation indicates that Spansion Inc. is developing one or more specific products, but has not committed any design to production. Information presented in a document with this designation is likely to change, and in some cases, development on the product may discontinue. Spansion Inc. therefore places the following conditions upon Advance Information content: “This document contains information on one or more products under development at Spansion Inc. The information is intended to help you evaluate this product. Do not design in this product without contacting the factory. Spansion Inc. reserves the right to change or discontinue work on this proposed product without notice.” Preliminary The Preliminary designation indicates that the product development has progressed such that a commitment to production has taken place. This designation covers several aspects of the product life cycle, including product qualification, initial production, and the subsequent phases in the manufacturing process that occur before full production is achieved. Changes to the technical specifications presented in a Preliminary document should be expected while keeping these aspects of production under consideration. Spansion places the following conditions upon Preliminary content: “This document states the current technical specifications regarding the Spansion product(s) described herein. The Preliminary status of this document indicates that product qualification has been completed, and that initial production has begun. Due to the phases of the manufacturing process that require maintaining efficiency and quality, this document may be revised by subsequent versions or modifications due to changes in technical specifications.” Combination Some data sheets contain a combination of products with different designations (Advance Information, Preliminary, or Full Production). This type of document distinguishes these products and their designations wherever necessary, typically on the first page, the ordering information page, and pages with the DC Characteristics table and the AC Erase and Program table (in the table notes). The disclaimer on the first page refers the reader to the notice on this page. Full Production (No Designation on Document) When a product has been in production for a period of time such that no changes or only nominal changes are expected, the Preliminary designation is removed from the data sheet. Nominal changes may include those affecting the number of ordering part numbers available, such as the addition or deletion of a speed option, temperature range, package type, or VIO range. Changes may also include those needed to clarify a description or to correct a typographical error or incorrect specification. Spansion Inc. applies the following conditions to documents in this category: “This document states the current technical specifications regarding the Spansion product(s) described herein. Spansion Inc. deems the products to have been in sufficient production volume such that subsequent versions of this document are not expected to change.

Sheet (Pre limin ar y) Product Overview The S29GL-P family consists of 1 Gb, 512 Mb, 256 Mb and 128 Mb, 3.0-volt-only, page mode Flash devices optimized for today’s embedded designs that demand a large storage array and rich functionality. These devices are manufactured using 90 nm MirrorBit technology. These products offer uniform 64 Kword (128 Kb) uniform sectors and feature VersatileIO control, allowing control and I/O signals to operate from 1.65 V to VCC. Additional features include: Single word programming or a 32-word buffer for an increased programming speed Program Suspend/Resume and Erase Suspend/Resume Advanced Sector Protection methods for protecting sectors as required 128 words/256 bytes of Secured Silicon area for storing customer and factory secured information. The Secured Silicon Sector is One Time Programmable. 6.1 Memory Map The S29GL-P devices consist of uniform 64 Kword (128 Kb) sectors organized as shown in Table 6.1– Table 6.4.

For example, all 128 Kb sectors have the pattern xxx0000h-xxxFFFFh. 7. Device Operations This section describes the read, program, erase, handshaking, and reset features of the Flash devices. Operations are initiated by writing specific commands or a sequence with specific address and data patterns into the command registers (see Table 12.1 through Table 12.4). The command register itself does not occupy any addressable memory location; rather, it is composed of latches that store the commands, along with the address and data information needed to execute the command. The contents of the register serve as input to the internal state machine and the state machine outputs dictate the function of the device. Writing incorrect address and data values or writing them in an improper sequence may place the device in an unknown state, in which case the system must pull the RESET# pin low or power cycle the device to return the device to the reading array data mode. 7.1 Device Operation Table The device must be setup appropriately for each operation. Table 7.1 describes the required state of each control pin for any particular operation.

All sectors are unprotected when shipped from the factory (The Secured Silicon Sector can be factory protected depending on version ordered.) 3. DIN or DOUT as required by command sequence, data polling, or sector protect algorithm. November 8, 2007 S29GL-P_00_A7 S29GL-P MirrorBit® Flash Family 19 Data 7.2 Sheet (Pre limin ar y) 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. 7.3 VersatileIOTM (VIO) Control The VersatileIOTM (VIO) control allows the host system to set the voltage levels that the device generates and tolerates on all inputs and outputs (address, control, and DQ signals). VIO range is 1.65 to VCC. See Ordering Information on page 9 for VIO options on this device. For example, a VIO of 1.65-3.6 volts allows for I/O at the 1.8 or 3 volt levels, driving and receiving signals to and from other 1.8 or 3 V devices on the same data bus. 7.4 Read All memories require access time to output array data. In a read operation, data is read from one memory location at a time. Addresses are presented to the device in random order, and the propagation delay through the device causes the data on its outputs to arrive with the address on its inputs. The device defaults to reading array data after device power-up or hardware reset. To read data from the memory array, the system must first assert a valid address on Amax-A0, while driving OE# and CE# to VIL. WE# must remain at VIH. All addresses are latched on the falling edge of CE#. Data will appear on DQ15DQ0 after address access time (tACC), which is equal to the delay from stable addresses to valid output data. The OE# signal must be driven to VIL. Data is output on DQ15-DQ0 pins after the access time (tOE) has elapsed from the falling edge of OE#, assuming the tACC access time has been meet. 7.5 Page Read Mode 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 8 words/16 bytes. The appropriate page is selected by the higher address bits A(max)-A3. Address bits A2-A0 in word mode (A2 to A-1 in byte mode) determine the specific word within a page. 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 tACC or tCE. Fast page mode accesses are obtained by keeping the “read-page addresses” constant and changing the “intra-read page” addresses. 20 S29GL-P MirrorBit® Flash Family S29GL-P_00_A7 November 8, 2007 Da ta 7.6 Shee t (Prelimi nar y) Autoselect The Autoselect mode provides manufacturer ID, Device identification, and sector protection information, through identifier codes output from the internal register (separate from the memory array) on DQ7-DQ0. This mode is primarily intended for programming equipment to automatically match a device to be programmed with its corresponding programming algorithm (see Table 7.3). The Autoselect codes can also be accessed in-system. There are two methods to access autoselect codes. One uses the autoselect command, the other applies VID on address pin A9. When using programming equipment, the autoselect mode requires VID (11.5 V to 12.5 V) on address pin A9. Address pins must be as shown in Table 7.2. To access Autoselect mode without using high voltage on A9, the host system must issue the Autoselect command. The Autoselect command sequence may be written to an address within a sector 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 system must write the reset command to return to the read mode (or erase-suspend-read mode if the sector was previously in Erase Suspend). It is recommended that A9 apply VID after power-up sequence is completed. In addition, it is recommended that A9 apply from VID to VIH/VIL before power-down the VCC/VIO. See Table 12.1 on page 68 for command sequence details. When verifying sector protection, the sector address must appear on the appropriate highest order address bits (see Table 7.4 to Table 7.5). The remaining address bits are don't care. When all necessary bits have been set as required, the programming equipment may then read the corresponding identifier code on DQ15-DQ0. The Autoselect codes can also be accessed in-system through the command register.

During a write operation, the system must drive CE# and WE# to VIL and OE# to VIH when providing address, command, and data. Addresses are latched on the last falling edge of WE# or CE#, while data is latched on the 1st rising edge of WE# or CE#. The Unlock Bypass feature allows the host system to send program commands to the Flash device without first writing unlock cycles within the command sequence. See Section 7.7.8 for details on the Unlock Bypass function. Note the following: When the Embedded Program algorithm is complete, the device returns to the read mode. The system can determine the status of the program operation by reading the DQ status bits. Refer to the Write Operation Status on page 36 for information on these status bits. An “0” cannot be programmed back to a “1.” A succeeding read shows that the data is still “0.” Only erase operations can convert a “0” to a “1.” Any commands written to the device during the Embedded Program/Erase are ignored except the Suspend commands. Secured Silicon Sector, Autoselect, and CFI functions are unavailable when a program operation is in progress. A hardware reset and/or power removal immediately terminates the Program/Erase operation and the Program/Erase command sequence should be reinitiated once the device has returned to the read mode to ensure data integrity. Programming is allowed in any sequence and across sector boundaries for single word programming operation. See Write Buffer Programming on page 26 when using the write buffer. Programming to the same word address multiple times without intervening erases is permitted. 7.7.1 Single Word Programming Single word programming mode is one method of programming the Flash. In this mode, four Flash command write cycles are used to program an individual Flash address. The data for this programming operation could be 8 or 16-bits wide. While the single word programming method is supported by most Spansion devices, in general Single Word Programming is not recommended for devices that support Write Buffer Programming. See Table 12.1 on page 68 for the required bus cycles and Figure 7.1 for the flowchart. 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 reading the DQ status bits. Refer to Write Operation Status on page 36 for information on these status bits. During programming, any command (except the Suspend Program command) is ignored. The Secured Silicon Sector, Autoselect, and CFI functions are unavailable when a program operation is in progress. 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. Programming to the same address multiple times continuously (for example, “walking” a bit within a word) is permitted. 24 S29GL-P MirrorBit® Flash Family S29GL-P_00_A7 November 8, 2007 Da ta Shee t (Prelimi nar y) Figure 7.1 Single Word Program Write Unlock Cycles: Address 555h, Data AAh Address 2AAh, Data 55h Unlock Cycle 1 Unlock Cycle 2 Write Program Command: Address 555h, Data A0h Setup Command Program Address (PA), Program Data (PD) Program Data to Address: PA, PD Perform Polling Algorithm (see Write Operation Status flowchart) Polling Status = Busy?

This results in a faster effective word programming time than the standard “word” 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 occurs. At this point, the system writes the number of “word locations minus 1” that are loaded into the page buffer at the Sector Address in which programming occurs. This tells the device how many write buffer addresses are loaded with data and therefore when to expect the “Program Buffer to Flash” confirm command. The number of locations to program cannot exceed the size of the write buffer or the operation aborts. (Number loaded = the number of locations to program minus 1. For example, if the system programs 6 address locations, then 05h should be written to the device.) The system then writes the starting address/data combination. This starting address is the first address/data pair to be programmed, and selects the “write-buffer-page” address. All subsequent address/data pairs must fall within the elected-write-buffer-page. The “write-buffer-page” is selected by using the addresses AMAX–A5. The “write-buffer-page” addresses 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 ABORTs.) After writing the Starting Address/Data pair, the system then writes the remaining address/data pairs into the write buffer. Note that if a Write Buffer address location is loaded multiple times, the “address/data pair” counter is decremented for every data load operation. Also, the last data loaded at a location before the “Program Buffer to Flash” confirm command is the data programmed into the device. It is the software's responsibility to comprehend ramifications of loading a write-buffer location more than once. The counter decrements for each data load operation, NOT for each unique write-buffer-address location. 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/data write combinations abort the Write Buffer Programming operation. The Write Operation Status bits should be used while monitoring the last address location loaded into the write buffer. This eliminates the need to store an address in memory because the system can load the last address location, issue the program confirm command at the last loaded address location, and then check the write operation status at that same address. DQ7, DQ6, DQ5, DQ2, and DQ1 should be monitored to determine the device status during Write Buffer Programming. 26 S29GL-P MirrorBit® Flash Family S29GL-P_00_A7 November 8, 2007 Da ta Shee t (Prelimi nar y) The write-buffer “embedded” programming operation can be suspended using the standard suspend/resume commands. Upon successful completion of the Write Buffer Programming operation, the device returns to READ mode. The Write Buffer Programming Sequence is ABORTED under any of the following conditions: 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. Writing anything other than the Program to Buffer Flash 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, DQ5 = 0. This indicates that the Write Buffer Programming Operation was ABORTED. A “Write-toBuffer-Abort reset” command sequence is required when using the write buffer Programming features in Unlock Bypass mode. Note that the Secured Silicon sector, autoselect, and CFI functions are unavailable when a program operation is in progress. Write buffer programming is allowed in any sequence of memory (or address) locations. These flash devices are capable of handling multiple write buffer programming operations on the same write buffer address range without intervening erases. Use of the write buffer is strongly recommended for programming when multiple words are to be programmed.

The device does not require the system to preprogram a sector prior to erase. The Embedded Erase algorithm automatically programs and verifies the entire memory to an all zero data pattern prior to electrical erase. After a successful sector erase, all locations within the erased sector contain FFFFh. 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 no less than tSEA occurs. During the timeout period, additional sector addresses 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. Any sector erase address and command following the exceeded time-out (50µs) may or may not be accepted. Any command other than Sector Erase or Erase Suspend during the time-out period resets that sector to the read mode. The system can monitor DQ3 to determine if the sector erase timer has timed out (See Section 7.8.6.) 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 sector returns to reading array data and addresses are no longer latched. The system can determine the status of the erase operation by reading DQ7 or DQ6/DQ2 in the erasing sector. Refer to Section 7.8 for information on these status bits. Once the sector erase operation has begun, only the Erase Suspend command is valid. All other commands are ignored. However, note that a hardware reset immediately terminates the erase operation. If that occurs, the sector erase command sequence should be reinitiated once that sector has returned to reading array data, to ensure the sector is properly erased. The Unlock Bypass feature allows the host system to send program commands to the Flash device without first writing unlock cycles within the command sequence. See Section 7.7.8 for details on the Unlock Bypass function. Figure 7.3 illustrates the algorithm for the erase operation. Refer to Section 11.7.5 for parameters and timing diagrams.

The Erase Suspend command is ignored if written during the chip erase operation. When the Erase Suspend command is written during the sector erase operation, the device requires a maximum of 20 µs (5 µs typical) 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. 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. Refer to Table 7.35 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 write operation status bits, just as in the standard program operation. In the erase-suspend-read mode, the system can also issue the Autoselect command sequence. Refer to Write Buffer Programming on page 26 and the Autoselect on page 21 for details. To resume the sector erase operation, the system must write the Erase Resume command. The address of the erase-suspended sector is required when writing this command. Further writes of the Resume command are ignored. Another Erase Suspend command can be written after the chip has resumed erasing.

When the Program Suspend command is written during a programming process, the device halts the programming operation within 15 µs maximum (5 µs typical) and updates the status bits. Addresses are “don't-cares” when writing the Program Suspend command. 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 within a sector in Erase Suspend or Program Suspend. If a read is needed from the Secured Silicon Sector 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 Program Suspend mode. The device allows reading Autoselect codes in the suspended sectors, since the codes are not stored in the memory array. When the device exits the Autoselect mode, the device reverts to Program Suspend mode, and is ready for another valid operation. See Autoselect on page 21 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 write operation status bits, just as in the standard program operation. See Write Operation Status on page 36 for more information. 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 Program Resume command are ignored. Another Program Suspend command can be written after the device has resumed programming.

This method is faster than the standard program command sequences. Note The accelerated program functions must not be used more than 10 times per sector. If the system asserts VHH on this input, the device automatically enters the aforementioned Unlock Bypass mode and uses the higher voltage on the input to reduce the time required for program operations. The system can then use the Write Buffer Load command sequence provided by the Unlock Bypass mode. Note that if a “Write-to-Buffer-Abort Reset” is required while in Unlock Bypass mode, the full 3-cycle RESET command sequence must be used to reset the device. Removing VHH from the ACC input, upon completion of the embedded program operation, returns the device to normal operation. Sectors must be unlocked prior to raising WP#/ACC to VHH. The WP#/ACC pin must not be at VHH for operations other than accelerated programming, or device damage may result. It is recommended that WP#/ACC apply VHH after power-up sequence is completed. In addition, it is recommended that WP#/ACC apply from VHH to VIH/VIL before powering down VCC/VIO. 7.7.8 Unlock Bypass This device features an Unlock Bypass mode to facilitate shorter programming commands. Once the device enters the Unlock Bypass mode, only two write cycles are required to program data, instead of the normal four cycles. This mode dispenses with the initial two unlock cycles required in the standard program command sequence, resulting in faster total programming time. The Command Definitions on page 67 shows the requirements for the unlock bypass command sequences. During the unlock bypass mode, only the Read, Program, Write Buffer Programming, Write-to-Buffer-Abort Reset, 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 sector address and the data 90h. The second cycle need only contain the data 00h. The sector then returns to the read mode. Software Functions and Sample Code The following are C source code examples of using the unlock bypass entry, program, and exit functions.

The following subsections describe the function of DQ1, DQ2, DQ3, DQ5, DQ6, and DQ7. 7.8.1 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. Note that the Data# Polling is valid only for the last word being programmed in the write-buffer-page during Write Buffer Programming. Reading Data# Polling status on any word other than the last word to be programmed in the write-buffer-page returns false status information. 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, then that sector 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 DQ6-DQ0 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 36 S29GL-P MirrorBit® Flash Family S29GL-P_00_A7 November 8, 2007 Da ta Shee t (Prelimi nar y) the status or valid data. Even if the device has completed the program or erase operation and DQ7 has valid data, the data outputs on DQ6-DQ0 may be still invalid. Valid data on DQ7-D00 appears on successive read cycles. See the following for more information: Table 7.17, shows the outputs for Data# Polling on DQ7. Figure 7.4, shows the Data# Polling algorithm; and Figure 11.7, shows the Data# Polling timing diagram.

Use the RESET command to exit operation. 4) Write buffer error if DQ1 of last read =1. 5) Invalid state, use RESET command to exit operation. 6) Valid data is the data that is intended to be programmed or all 1's for an erase operation. 7) Data polling algorithm valid for all operations except advanced sector protection. S29GL-P MirrorBit® Flash Family 37 Data 7.8.2 Sheet (Pre limin ar y) 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 that is being programmed or erased causes DQ6 to toggle. 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 100μs, 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 DQ7: Data# Polling on page 36). If a program address falls within a protected sector, DQ6 toggles for approximately 1μs 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. See the following for additional information: Figure 7.4, Figure 11.13 on page 63, and Table 7.17. Toggle Bit I on DQ6 requires either OE# or CE# to be de-asserted and reasserted to show the change in state. 7.8.3 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. 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 7.17 to compare outputs for DQ2 and DQ6. See Figure 11.14 on page 63 for additional information. 7.8.4 Reading Toggle Bits DQ6/DQ2 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 erases 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 DQ5: Exceeded Timing Limits on page 39). 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 erases operation. If it is still toggling, the device did not complete the operation successfully, and the system must write the reset command to return to reading array data. The remaining scenario is that the system initially determines that the toggle bit is toggling and 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. Refer to Figure 7.4 for more details. Note When verifying the status of a write operation (embedded program/erase) of a memory sector, DQ6 and DQ2 toggle between high and low states in a series of consecutive and contiguous status read cycles. In order for 38 S29GL-P MirrorBit® Flash Family S29GL-P_00_A7 November 8, 2007 Da ta Shee t (Prelimi nar y) this toggling behavior to be properly observed, the consecutive status bit reads must not be interleaved with read accesses to other memory sectors. If it is not possible to temporarily prevent reads to other memory sectors, then it is recommended to use the DQ7 status bit as the alternative method of determining the active or inactive status of the write operation. 7.8.5 DQ5: Exceeded Timing Limits DQ5 indicates whether the program or erase time has exceeded a specified internal pulse count limit. Under these conditions DQ5 produces a “1,” indicating that the program or erase cycle was not successfully completed. The device does not output a 1 on DQ5 if the system tries to program a 1 to a location that was previously programmed to 0. Only an erase operation can change a 0 back to a 1. Under this condition, the device ignores the bit that was incorrectly instructed to be programmed from a 0 to a 1, while any other bits that were correctly requested to be changed from 1 to 0 are programmed. Attempting to program a 0 to a 1 is masked during the programming operation. Under valid DQ5 conditions, the system must write the reset command to return to the read mode (or to the erase-suspend-read mode if a sector was previously in the erase-suspend-program mode). 7.8.6 DQ3: Sector Erase Timeout State Indicator After writing a sector erase command sequence, the system may read DQ3 to determine whether or not erasure has begun. (The sector erase timer does not apply to the chip erase command.) If additional sectors are selected for erasure, the entire time-out also applies after each additional sector erase command. When the time-out period is complete, DQ3 switches from a “0” to a “1.” If the time between additional sector erase commands from the system can be assumed to be less than tSEA, then the system need not monitor DQ3. See Sector Erase on page 30 for more details. 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 accepts 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 sub-sequent sector erase command. If DQ3 is high on the second status check, the last command might not have been accepted. Table 7.17 shows the status of DQ3 relative to the other status bits. 7.8.7 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 26 for more details.

DQ5 switches to 1 when an Embedded Program, Embedded Erase, or Write-to-Buffer operation has exceeded the maximum timing limits. Refer toDQ5: Exceeded Timing Limits on page 39 for more information. 2. DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate subsection for further details. 3. The Data# Polling algorithm should be used to monitor the last loaded write-buffer address location. 4. DQ1 switches to 1 when the device has aborted the write-to-buffer operation 7.9 Writing Commands/Command Sequences During a write operation, the system must drive CE# and WE# to VIL and OE# to VIH when providing an address, command, and data. Addresses are latched on the last falling edge of WE# or CE#, while data is latched on the 1st rising edge of WE# or CE#. An erase operation can erase one sector, multiple sectors, or the entire device. Table 6.2–Table 6.3 indicate the address space that each sector occupies. The device address space is divided into uniform 64KW/128KB sectors. A sector address is the set of address bits required to uniquely select a sector. ICC2 in “DC Characteristics” represents the active current specification for the write mode. “AC Characteristics” contains timing specification tables and timing diagrams for write operations. 7.9.1 RY/BY# 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. This feature allows the host system to detect when data is ready to be read by simply monitoring the RY/BY# pin, which is a dedicated output and controlled by CE# (not OE#). 7.9.2 Hardware Reset The RESET# input provides a hardware method of resetting the device to reading array data. When RESET# is driven low for at least a period of tRP (RESET# Pulse Width), the device immediately terminates any operation in progress, tristates all outputs, resets the configuration register, 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. To ensure data integrity Program/Erase operations that were interrupted should be reinitiated once the device is ready to accept another command sequence. When RESET# is held at VSS, the device draws VCC reset current (ICC5). If RESET# is held at VIL, but not at VSS, the standby current is greater. RESET# may be tied to the system reset circuitry which enables the system to read the boot-up firmware from the Flash memory upon a system reset. See Figure 11.7 on page 58 and Figure 11.8 on page 59 for timing diagrams. 40 S29GL-P MirrorBit® Flash Family S29GL-P_00_A7 November 8, 2007 Da ta 7.9.3 Shee t (Prelimi nar y) Software Reset Software reset is part of the command set (see Table 12.1 on page 68) that also returns the device to array read mode and must be used for the following conditions: 1. to exit Autoselect mode 2. when DQ5 goes high during write status operation that indicates program or erase cycle was not successfully completed 3. exit sector lock/unlock operation. 4. to return to erase-suspend-read mode if the device was previously in Erase Suspend mode. 5. after any aborted operations Software Functions and Sample Code Table 7.18 Reset (LLD Function = lld_ResetCmd) Cycle Operation Byte Address Word Address Data Reset Command Write Base + xxxh Base + xxxh 00F0h Note Base = Base Address.

Reset commands are ignored during program and erase operations. The reset command may be written between the cycles in a program command sequence before programming begins (prior to the third cycle). This resets the sector to which the system was writing to the read mode. If the program command sequence is written to a sector that is in the Erase Suspend mode, writing the reset command returns that sector to the erase-suspend-read mode. The reset command may be written during an Autoselect command sequence. If a sector has entered the Autoselect mode while in the Erase Suspend mode, writing the reset command returns that sector to the erase-suspend-read mode. 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 to reading array data. The standard RESET command does not work during this condition. To exit the unlock bypass mode, the system must issue a two-cycle unlock bypass reset command sequence [see Command Definitions on page 67 for details].

Sheet (Pre limin ar y) Advanced Sector Protection/Unprotection The Advanced Sector Protection/Unprotection feature disables or enables programming or erase operations in any or all sectors and can be implemented through software and/or hardware methods, which are independent of each other. This section describes the various methods of protecting data stored in the memory array. An overview of these methods in shown in Figure 8.1.

S29GL-P_00_A7 November 8, 2007 Da ta 8.1 Shee t (Prelimi nar y) Lock Register As shipped from the factory, all devices default to the persistent mode when power is applied, and all sectors are unprotected, unless otherwise chosen through the DYB ordering option (see Ordering Information on page 9). The device programmer or host system must then choose which sector protection method to use. Programming (setting to “0”) any one of the following two one-time programmable, non-volatile bits locks the part permanently in that mode: Lock Register Persistent Protection Mode Lock Bit (DQ1) Lock Register Password Protection Mode Lock Bit (DQ2) Table 8.1 Lock Register DQ15-3 DQ2 DQ1 DQ0 Don’t Care Password Protection Mode Lock Bit Persistent Protection Mode Lock Bit Secured Silicon Sector Protection Bit For programming lock register bits refer to Table 12.2 on page 69 and Table 12.4 on page 71. Notes 1. If the password mode is chosen, the password must be programmed before setting the corresponding lock register bit. 2. After the Lock Register Bits Command Set Entry command sequence is written, reads and writes for Sector 0 are disabled, while reads from other sectors are allowed until exiting this mode. 3. If both lock bits are selected to be programmed (to zeros) at the same time, the operation aborts. 4. Once the Password Mode Lock Bit is programmed, the Persistent Mode Lock Bit is permanently disabled, and no changes to the protection scheme are allowed. Similarly, if the Persistent Mode Lock Bit is programmed, the Password Mode is permanently disabled. After selecting a sector protection method, each sector can operate in any of the following three states: 1. Constantly locked. The selected sectors are protected and can not be reprogrammed unless PPB lock bit is cleared via a password, hardware reset, or power cycle. 2. Dynamically locked. The selected sectors are protected and can be altered via software commands. 3. Unlocked. The sectors are unprotected and can be erased and/or programmed. These states are controlled by the bit types described in Section 8.2–Section 8.5. 8.2 Persistent Protection Bits The Persistent Protection Bits are unique and nonvolatile for each sector and have the same endurances as the Flash memory. Preprogramming and verification prior to erasure are handled by the device, and therefore do not require system monitoring. Notes 1. Each PPB is individually programmed and all are erased in parallel. 2. While programming PPB for a sector, array data can be read from any other sector, except Sector 0 (used for Data# Polling) and the sector in which sector PPB is being programmed. 3. Entry command disables reads and writes for the sector selected. 4. Reads within that sector return the PPB status for that sector. 5. All Reads must be performed using the read mode. 6. The specific sector address (A25-A16 GL01GP, A24-A16 GL512P, A23-A16 GL256P, A22-A16 GL128P) are written at the same time as the program command. 7. If the PPB Lock Bit is set, the PPB Program or erase command does not execute and times-out without programming or erasing the PPB.

There are no means for individually erasing a specific PPB and no specific sector address is required for this operation. 9. Exit command must be issued after the execution which resets the device to read mode and reenables reads and writes for Sector 0. 10. The programming state of the PPB for a given sector can be verified by writing a PPB Status Read Command to the device as described by the flow chart shown in Figure 8.2.

DYBs only control the protection scheme for unprotected sectors that have their PPBs cleared (erased to “1”). By issuing the DYB Set or Clear command sequences, the DYBs are set (programmed to “0”) or cleared (erased to “1”), thus placing each sector in the protected or unprotected state respectively. This feature allows software to easily protect sectors against inadvertent changes yet does not prevent the easy removal of protection when changes are needed. Notes 1. The DYBs can be set (programmed to “0”) or cleared (erased to “1”) as often as needed. When the parts are first shipped, the PPBs are cleared (erased to “1”) and upon power up or reset, the DYBs can be set or cleared depending upon the ordering option chosen. 2. If the option to clear the DYBs after power up is chosen, (erased to “1”), then the sectorsmay be modified depending upon the PPB state of that sector (see Table 8.2). 3. The sectors would be in the protected state If the option to set the DYBs after power up is chosen (programmed to “0”). 4. It is possible to have sectors that are persistently locked with sectors that are left in the dynamic state. 5. The DYB Set or Clear commands for the dynamic sectors signify protected or unprotectedstate of the sectors respectively. However, if there is a need to change the status of the persistently locked sectors, a few more steps are required. First, the PPB Lock Bit must be cleared by either putting the device through a power-cycle, or hardware reset. The PPBs can then be changed to reflect the desired settings. Setting the PPB Lock Bit once again locks the PPBs, and the device operates normally again. 6. To achieve the best protection, it is recommended to execute the PPB Lock Bit Set command early in the boot code and protect the boot code by holding WP#/ACC = VIL. Note that the PPB and DYB bits have the same function when WP#/ACC = VHH as they do when ACC =VIH. 8.3 Persistent Protection Bit Lock Bit The Persistent Protection Bit Lock Bit is a global volatile bit for all sectors. When set (programmed to “0”), it locks all PPBs and when cleared (programmed to “1”), allows the PPBs to be changed. There is only one PPB Lock Bit per device. Notes 1. No software command sequence unlocks this bit unless the device is in the password protection mode; only a hardware reset or a power-up clears this bit. 2. The PPB Lock Bit must be set (programmed to “0”) only after all PPBs are configured to the desired settings. 8.4 Password Protection Method The Password Protection Method allows an even higher level of security than the Persistent Sector Protection Mode by requiring a 64-bit password for unlocking the device PPB Lock Bit. In addition to this password requirement, after power up and reset, the PPB Lock Bit is set “0” to maintain the password mode of operation. Successful execution of the Password Unlock command by entering the entire password clears the PPB Lock Bit, allowing for sector PPBs modifications. Notes 1. There is no special addressing order required for programming the password. Once the Password is written and verified, the Password Mode Locking Bit must be set in order to prevent access. 2. The Password Program Command is only capable of programming “0”s. Programming a “1” after a cell is programmed as a “0” results in a time-out with the cell as a “0”. 3. The password is all “1”s when shipped from the factory. 4. All 64-bit password combinations are valid as a password. November 8, 2007 S29GL-P_00_A7 S29GL-P MirrorBit® Flash Family 45 Data Sheet (Pre limin ar y) 5. There is no means to verify what the password is after it is set. 6. The Password Mode Lock Bit, once set, prevents reading the 64-bit password on the data bus and further password programming. 7. The Password Mode Lock Bit is not erasable. 8. The lower two address bits (A1–A0) are valid during the Password Read, Password Program, and Password Unlock. 9. The exact password must be entered in order for the unlocking function to occur. 10. The Password Unlock command cannot be issued any faster than 1 µs at a time to prevent a hacker from running through all the 64-bit combinations in an attempt to correctly match a password. 11. Approximately 1 µs is required for unlocking the device after the valid 64-bit password is given to the device. 12. Password verification is only allowed during the password programming operation. 13. All further commands to the password region are disabled and all operations are ignored. 14. If the password is lost after setting the Password Mode Lock Bit, there is no way to clear the PPB Lock Bit. 15. Entry command sequence must be issued prior to any of any operation and it disables reads and writes for Sector 0. Reads and writes for other sectors excluding Sector 0 are allowed. 16. If the user attempts to program or erase a protected sector, the device ignores the command and returns to read mode. 17. A program or erase command to a protected sector enables status polling and returns to read mode without having modified the contents of the protected sector. 18. The programming of the DYB, PPB, and PPB Lock for a given sector can be verified by writing individual status read commands DYB Status, PPB Status, and PPB Lock Status to the device. 46 S29GL-P MirrorBit® Flash Family S29GL-P_00_A7 November 8, 2007 Da ta Shee t (Prelimi nar y) Figure 8.3 Lock Register Program Algorithm Write Unlock Cycles: Address 555h, Data AAh Address 2AAh, Data 55h Unlock Cycle 1 Unlock Cycle 2 Write Enter Lock Register Command: Address 555h, Data 40h XXXh = Address don’t care Program Lock Register Data Address XXXh, Data A0h Address XXXh*, Data PD Program Data (PD): See text for Lock Register definitions Caution: Lock register can only be progammed once.

In summary, if the PPB Lock Bit is locked (set to “0”), no changes to the PPBs are allowed. The PPB Lock Bit can only be unlocked (reset to “1”) through a hardware reset or power cycle. See also Figure 8.1 for an overview of the Advanced Sector Protection feature. 8.6 Hardware Data Protection Methods The device offers two main types of data protection at the sector level via hardware control: When WP#/ACC is at VIL, the either the highest or lowest sector is locked (device specific). There are additional methods by which intended or accidental erasure of any sectors can be prevented via hardware means. The following subsections describes these methods: 8.6.1 WP#/ACC Method The Write Protect feature provides a hardware method of protecting one outermost sector. This function is provided by the WP#/ACC pin and overrides the previously discussed Sector Protection/Unprotection method. If the system asserts VIL on the WP#/ACC pin, the device disables program and erase functions in the highest or lowest sector independently of whether the sector was protected or unprotected using the method described in Advanced Sector Protection/Unprotection on page 42. If the system asserts VIH on the WP#/ACC pin, the device reverts to whether the boot sectors were last set to be protected or unprotected. That is, sector protection or unprotection for these sectors depends on whether they were last protected or unprotected. The WP#/ACC pin must be held stable during a command sequence execution. WP# has an internal pull-up; when unconnected, WP# is set at VIH. Note If WP#/ACC is at VIL when the device is in the standby mode, the maximum input load current is increased. See Table 11.6 on page 55 for details. 8.6.2 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 reading array data. Subsequent writes are ignored until VCC is greater than VLKO. The system must provide the proper signals to the control inputs to prevent unintentional writes when VCC is greater than VLKO. 48 S29GL-P MirrorBit® Flash Family S29GL-P_00_A7 November 8, 2007 Da ta 8.6.3 Shee t (Prelimi nar y) Write Pulse “Glitch Protection” Noise pulses of less than 5 ns (typical) on OE#, CE# or WE# do not initiate a write cycle. 8.6.4 Power-Up Write Inhibit If WE# = CE# = RESET# = 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. 9. Power Conservation Modes 9.1 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# inputs are both held at VCC ± 0.3 V. The device requires standard access time (tCE) for read access, 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. ICC4 in “DC Characteristics” represents the standby current specification 9.2 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 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. ICC6 in Section 11.6 represents the automatic sleep mode current specification. 9.3 Hardware RESET# Input Operation The RESET# input provides a hardware method of resetting the device to reading array data. When RESET# is driven low for at least a period of tRP, the device immediately terminates any operation in progress, tristates all outputs, 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. When RESET# is held at VSS ± 0.3 V, the device draws ICC reset current (ICC5). If RESET# is held at VIL but not within VSS ± 0.3 V, the standby current is greater. RESET# may be tied to the system reset circuitry and thus, a system reset would also reset the Flash memory, enabling the system to read the boot-up firmware from the Flash memory. 9.4 Output Disable (OE#) When the OE# input is at VIH, output from the device is disabled. The outputs are placed in the high impedance state. (With the exception of RY/BY#.) November 8, 2007 S29GL-P_00_A7 S29GL-P MirrorBit® Flash Family 49 Data Sheet (Pre limin ar y) 10. Secured Silicon Sector Flash Memory Region The Secured Silicon Sector provides an extra Flash memory region that enables permanent part identification through an Electronic Serial Number (ESN). The Secured Silicon Sector is 128 words in length and all Secured Silicon reads outside of the 128-word address range returns invalid data. The Secured Silicon Sector Indicator Bit, DQ7, (at Autoselect address 03h) is used to indicate whether or not the Secured Silicon Sector is locked when shipped from the factory. Please note the following general conditions: On power-up, or following a hardware reset, the device reverts to sending commands to the normal address space. Reads outside of sector SA0 return memory array data. Sector SA0 is remapped from memory array to Secured Silicon Sector array. Once the Secured Silicon Sector Entry Command is issued, the Secured Silicon Sector Exit command must be issued to exit Secured Silicon Sector Mode. The Secured Silicon Sector is not accessible when the device is executing an Embedded Program or Embedded Erase algorithm. The ACC function and unlock bypass modes are not available when the Secured Silicon Sector is enabled. Table 10.1 Secured Silicon Sector Addresses Secured Silicon Sector Address Range 000000h–000007h 000008h–00007Fh 10.1 Customer Lockable ESN Factory Locked ExpressFlash Factory Locked Determined by customer ESN ESN or determined by customer Unavailable Determined by customer Factory Locked Secured Silicon Sector The Factory Locked Secured Silicon Sector is always protected when shipped from the factory and has the Secured Silicon Sector Indicator Bit (DQ7) permanently set to a “1”. This prevents cloning of a factory locked part and ensures the security of the ESN and customer code once the product is shipped to the field. These devices are available pre-programmed with one of the following: A random, 8 Word secure ESN only within the Secured Silicon Sector (at addresses 000000H - 000007H) Both a random, secure ESN and customer code through the Spansion programming service. Customers may opt to have their code programmed through the Spansion programming services. Spansion programs the customer's code, with or without the random ESN. The devices are then shipped from the Spansion factory with the Secured Silicon Sector permanently locked. Contact your local representative for details on using Spansion programming services. 10.2 Customer Lockable Secured Silicon Sector The Customer Lockable Secured Silicon Sector is always shipped unprotected (DQ7 set to “0”), allowing customers to utilize that sector in any manner they choose. If the security feature is not required, the Secured Silicon Sector can be treated as an additional Flash memory space. Please note the following: Once the Secured Silicon Sector area is protected, the Secured Silicon Sector Indicator Bit is permanently set to “0.” The Secured Silicon Sector can be read any number of times, but can be programmed and locked only once. The Secured Silicon Sector lock must be used with caution as once locked, there is no procedure available for unlocking the Secured Silicon Sector area and none of the bits in the Secured Silicon Sector memory space can be modified in any way. The accelerated programming (ACC) and unlock bypass functions are not available when the Secured Silicon Sector is enabled. 50 S29GL-P MirrorBit® Flash Family S29GL-P_00_A7 November 8, 2007 Da ta Shee t (Prelimi nar y) Once the Secured Silicon Sector is locked and verified, the system must write the Exit Secured Silicon Sector Region command sequence which return the device to the memory array at sector 0. 10.3 Secured Silicon Sector Entry/Exit Command Sequences 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. See Command Definitions on page 67 [Secured Silicon Sector Command Table, Appendix Table 12.1 on page 68 through Table 12.4 on page 71 for address and data requirements for both command sequences. The Secured Silicon Sector Entry Command allows the following commands to be executed Read customer and factory Secured Silicon areas Program the customer Secured Silicon Sector 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 sector SA0 within the memory array. This mode of operation continues until the system issues the Exit Secured Silicon Sector command sequence, or until power is removed from the device. Software Functions and Sample Code The following are C functions and source code examples of using the Secured Silicon Sector Entry, Program, and exit commands.

Typical program and erase times assume the following conditions: 25°C, 3.6 V VCC, 10,000 cycles, checkerboard pattern. 2. Under worst case conditions of -40°C, VCC = 3.0 V, 100,000 cycles. 3. Effective write buffer specification is based upon a 32-word write buffer operation. 4. The typical chip programming time is considerably less than the maximum chip programming time listed, since most words program faster than the maximum program times listed. 5. In the pre-programming step of the Embedded Erase algorithm, all bits are programmed to 00h before erasure. 6. System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command.

All bus cycles are write cycles unless otherwise noted. 4. Data bits DQ15-DQ8 are don’t cares for unlock and command cycles. 5. Address bits AMAX:A16 are don’t cares for unlock and command cycles, unless SA or PA required. (AMAX is the Highest Address pin.) 6. All Lock Register bits are one-time programmable. Program state = “0” and the erase state = “1.” The Persistent Protection Mode Lock Bit and the Password Protection Mode Lock Bit cannot be programmed at the same time or the Lock Register Bits Program operation aborts and returns the device to read mode. Lock Register bits that are reserved for future use default to “1’s.” The Lock Register is shipped out as “FFFF’s” before Lock Register Bit program execution. November 8, 2007 S29GL-P_00_A7 9. For PWDx, only one portion of the password can be programmed per each “A0” command. 10. Note that the password portion can be entered or read in any order as long as the entire 64-bit password is entered or read. 11. If ACC = VHH, sector protection matches when ACC = VIH. 12. Protected State = “00h,” Unprotected State = “01h.” 13. The All PPB Erase command embeds programming of all PPB bits before erasure. S29GL-P MirrorBit® Flash Family 71 Data 12.2 Sheet (Pre limin ar y) Common Flash Memory Interface 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 Tables 12.6–12.8). All reads outside of the CFI address range, returns non-valid data. Reads from other sectors are allowed, writes are not. 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 12.6–12.8. The system must write the reset command to return the device to reading array data. The following is a C source code example of using the CFI Entry and Exit functions. Refer to the Spansion Low Level Driver User’s Guide (available on www.spansion.com) for general information on Spansion Flash memory software development guidelines. /* Example: CFI Entry command */ *( (UINT16 *)base_addr + 0x55 ) = 0x0098; /* Example: CFI Exit command */ *( (UINT16 *)base_addr + 0x000 ) = 0x00F0; /* write CFI entry command /* write cfi exit command */ */ For further information, please refer to the CFI Specification (see JEDEC publications JEP137-A and JESD68.01and CFI Publication 100).
