Publication Number S29WS-P_00 Revision A Amendment 11 Issue Date September 28, 2007 Data Sheet 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. However, typographical or specification corrections, or modifications to the valid combinations offered may occur.” Questions regarding these document designations may be directed to your local sales office. 2 S29WS-P S29WS-P_00_A11 September 28, 2007 S29WS-P MirrorBit® Flash Family S29WS512P, S29WS256P, S29WS128P 512/256/128 Mb (32/16/8 M x 16 bit) 1.8 V Burst Simultaneous Read/Write MirrorBit Flash Memory Data Sheet Features Single 1.8 V read/program/erase (1.70–1.95 V) 90 nm MirrorBit™ Technology Simultaneous Read/Write operation with zero latency Random page read access mode of 8 words with 20 ns intra page access time 32 Word / 64 Byte Write Buffer Sixteen-bank architecture consisting of 32/16/8 Mwords for 512/256/128P, respectively Four 16 Kword sectors at both top and bottom of memory array 510/254/126 64Kword sectors (WS512/256/128P) Programmable linear (8/16/32) with or without wrap around and continuous burst read modes Secured Silicon Sector region consisting of 128 words each for factory and 128 words for customer 20-year data retention (typical) Cycling Endurance: 100,000 cycles per sector (typical) Command set compatible with JEDEC (42.4) standard Hardware (WP#) protection of top and bottom sectors Dual boot sector configuration (top and bottom) Handshaking by monitoring RDY Offered Packages – WS512P/WS256P/WS128P: 84-ball FBGA (11.6 mm x 8 mm) Low VCC write inhibit Persistent and Password methods of Advanced Sector Protection Write operation status bits indicate program and erase operation completion Suspend and Resume commands for Program and Erase operations Unlock Bypass program command to reduce programming time Synchronous or Asynchronous program operation, independent of burst control register settings ACC input pin to reduce factory programming time Support for Common Flash Interface (CFI) General Description The Spansion S29WS512/256/128P are Mirrorbit® Flash products fabricated on 90 nm process technology.

Device Operations This section describes the read, program, erase, simultaneous read/write operations, 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 on page 85 and Table 12.2 on page 87). 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 write the reset command to return the device to the reading array data mode. 18 S29WS-P S29WS-P_00_A11 September 28, 2007 Data Sheet 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.

In an asynchronous 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 asynchronously with the address on its inputs. The device defaults to reading array data asynchronously 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 AVD# and CE# to VIL. WE# must remain at VIH. The rising edge of AVD# latches the address, preventing changes to the address lines from effecting the address being accessed.. Data is output on DQ15-DQ0 pins after the access time (tACC) has elapsed from the falling edge of AVD#, or the last time the address lines changed while AVD# was low. September 28, 2007 S29WS-P_00_A11 S29WS-P 19 Data Sheet 7.3 Page Mode Read The device is capable of fast page mode read. This mode provides fast (tPACC) random read access speed for locations within a page. Address bits Amax–A3 select an 8 word page, and address bits A2–A0 select a specific word within that page. This is an asynchronous operation with the microprocessor supplying the specific word location. It does not matter if AVD# stays low or toggles. However, the address input must be always valid and stable if AVD# is low during the page read. The random or initial page access is tACC or tCE (depending on how the device was accessed) 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 (=VIH), the reassertion of CE# for subsequent access has access time of tCE. Here again, CE# selects the device and OE# is the output control and should be used to gate data to the output inputs if the device is selected. Fast page mode accesses are obtained by keeping Amax–A3 constant and changing A2–A0 to select the specific word within that page.

When the device first powers up, it is enabled for asynchronous read operations and can be automatically enabled for burst mode. To enter into synchronous mode, the configuration register will need to be set. Prior to entering burst mode, the system should determine how many wait states are desired for the initial word (tIACC) of each burst access, what mode of burst operation is desired and how the RDY signal will transition with valid data. The system would then write the configuration register command sequence. Once the system has written the Set Configuration Register command sequence, the device is enabled for synchronous reads only. The data is output tIACC after the rising edge of the first CLK. Subsequent words are output tBACC after the rising edge of each successive clock cycle, which automatically increments the internal address counter. Note that data is output only at the rising edge of the clock. RDY indicates the initial latency. 7.4.1 Latency Tables for Variable Wait State The following tables show the latency for variable wait state in a continuous Burst operation Table 7.3 Address Latency

Yes Completed 7.5.1 Continuous Burst Read Mode In the continuous burst read mode, the device outputs sequential burst data from the starting address given and then wraps around to address 000000h when it reaches the highest addressable memory location. The burst read mode continues until the system drives CE# high, or RESET#= VIL. Continuous burst mode can also be aborted by asserting AVD# low and providing a new address to the device. If the address being read crosses a 128-word line boundary with in the same bank, but not into a program or erase suspended sector (as mentioned above), additional latency cycles are required as reflected by the configuration register table (Table 7.31). If the address crosses a bank boundary while the subsequent bank is programming or erasing, the device provides read status information and the clock is ignored. Upon completion of status read or program or erase operation, the host can restart a burst read operation using a new address and AVD# pulse.

The groups are sized according to the number of words read in a single burst sequence for a given mode (see Table 7.30). For example, if the starting address in the 8-word mode is 3Ch, the address range to be read would be 383Fh, and the burst sequence would be 3C-3D-3E-3F-38-39-3A-3Bh. Thus, the device outputs all words in that burst address group until all word are read, regardless of where the starting address occurs in the address group, and then terminates the burst read. In a similar fashion, the 16-word and 32-word Linear Wrap modes begin their burst sequence on the starting address provided to the device, then wrap back to the first address in the selected address group. Note In this mode the address pointer does not cross the boundary that occurs every 128 words; thus, no additional wait states are inserted due to boundary crossing. Table 7.30 Burst Address Groups Mode 8-word 16-word 32-word Group Size 8 words 16 words 32 words 0-7h, 8-Fh, 10-17h,... 0-Fh, 10-1Fh, 20-2Fh,... 00-1Fh, 20-3Fh, 40-5Fh,... Group Address Ranges 7.5.3 8-, 16-, 32-Word Linear Burst without Wrap Around If wrap around is not enabled for linear burst read operations, the 8-word, 16-word, or 32-word burst executes up to the maximum memory address of the selected number of words. The burst stops after 8, 16, or 32 addresses and does not wrap around to the first address of the selected group. For example, if the starting address in the 8-word mode is 3Ch, the address range to be read would be 3Ch43h, and the burst sequence would be 3C-3D-3E-3F-40-41-42-43h if wrap around is not enabled. The next address to be read requires a new address and AVD# pulse. Note that in this burst read mode, the address pointer may cross the boundary that occurs every 128 words, which will incur the additional boundary crossing wait state. 30 S29WS-P S29WS-P_00_A11 September 28, 2007 Data Sheet 7.5.4 Configuration Registers This device uses two 16-bit configuration registers to set various operational parameters. Upon power-up or hardware reset, the device defaults to the asynchronous read mode, and the configuration register settings are in their default state. The host system should determine the proper settings for the entire configuration register, and then execute the Set Configuration Register command sequence before attempting burst operations. The Configuration Register can also be read using a command sequence (see Table 12.1 on page 85). The following list describes the register settings.

Refer to Table 12.1 on page 85 for reading the settings and writing onto configuration registers command sequences. 6. Configuration Registers can not be programmed out of order. CR0 must be programmed prior to CR01 otherwise the configuration registers will retain their previous settings. 7.6 Autoselect The Autoselect is used for manufacturer ID, Device identification, and sector protection information. This mode is primarily intended for programming equipment to automatically match a device with its corresponding programming algorithm. The Autoselect codes can also be accessed in-system. When verifying sector protection, the sector address must appear on the appropriate highest order address bits (see Table 7.32 on page 32). The remaining address bits are don't care. The most significant four bits of the address during the third write cycle selects the bank from which the Autoselect codes are read by the host. All other banks can be accessed normally for data read without exiting the Autoselect mode. To access the Autoselect codes, the host system must issue the Autoselect command. The Autoselect command sequence may be written to an address within a bank 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. Autoselect does not support simultaneous operations or burst mode. The system must write the reset command to return to the read mode (or erase-suspend-read mode if the bank was previously in Erase Suspend). See Table 12.1 on page 85 for command sequence details.

However, prior to any programming and or erase operation, devices must be setup appropriately as outlined in the configuration register (Table 7.31 on page 31). During synchronous write operations, including writing command sequences, the system must drive AVD# and CE# to VIL, and OE# to VIH when providing an address to the device, and drive WE# and CE# to VIL, and OE# to VIH when writing commands or programming data. Addresses are latched on the rising edge of AVD# pulse or rising edge of CLK or falling edge of WE#, whichever occurs first. During asynchronous write operations, addresses are latched on the rising edge of AVD# or falling edge of WE# while data is latched on the 1st rising edge of WE#, or CE# whichever comes first. Note the following: When the Embedded Program/Erase algorithm is complete, the device returns to the read mode. The system can determine the status of the Program/Erase operation. Refer to Write Operation Status on page 47 for further information. While 1 can be programmed to 0, a 0 cannot be programmed to a 1. Any such attempt will be ignored as only an erase operation can covert a 0 to a 1. For example: Old Data = 0011 New Data = 0101 Result = 0001 Any commands written to the device during the Embedded Program/Erase Algorithm are ignored except the Program/Erase Suspend commands. Secured Silicon Sector, Autoselect, and CFI functions are unavailable when a Program/Erase 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 only for single word programming operation. See Write Buffer Programming on page 36 when using the write buffer. 34 S29WS-P S29WS-P_00_A11 September 28, 2007 Data Sheet 7.7.1 Single Word Programming Single word programming mode is the simplest method of programming. In this mode, four Flash command write cycles are used to program an individual Flash address. While the single word programming method is supported by all Spansion devices, in general it is not recommended for devices that support Write Buffer Programming. See Table 12.1 on page 85 for the required bus cycles and Figure 7.3 for the flowchart. When the Embedded Program algorithm is complete, the device returns to the read mode and addresses are no longer latched. The system can determine the status of the program operation by using DQ7 or DQ6. Refer to the Write Operation Status section for information on these status bits.

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 will occur. At this point, the system writes the number of word locations minus 1 that will be loaded into the page buffer at the Sector Address in which programming will occur. This tells the device how many write buffer addresses will be 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 will abort. (NOTE: the size of the write buffer is dependent upon which data are being loaded. Also note that the number loaded = the number of locations to program minus 1. For example, if the system will program 6 address locations, then 05h should be written to the device.) The write-buffer addresses must be in the same sector for all address/data pairs loaded into the write buffer. It is to be noted that Write Buffer Programming cannot be performed across multiple sectors. If the system attempts to load programming data outside of the selected write-buffer addresses, the operation aborts after the Write to Buffer command is executed. Also, the starting address must be the least significant address. All subsequent addresses and write buffer data must be in sequential order. 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 be in sequential order. After writing the Starting Address/Data pair, the system then writes the remaining address/data pairs into the write buffer. Write buffer locations must be loaded in sequential order starting with the lowest address in the page. Note that if the number of address/data pairs do no match the word count, the program buffer to flash command is ignored. Note that if a Write Buffer address location is loaded multiple times, the address/data pair counter will be decremented for every data load operation. Also, the last data loaded at a location before the Program Buffer to Flash confirm command will be 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 will abort the Write Buffer Programming operation. The device will then go busy. The Data Bar polling techniques 36 S29WS-P S29WS-P_00_A11 September 28, 2007 Data Sheet 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 data bar poll at that same address. DQ7, DQ6, DQ5, DQ2, and DQ1 should be monitored to determine the device status during Write Buffer Programming. 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 will return to READ mode. The Write Buffer Programming Sequence is ABORTED in the following ways: Load a value that is greater than the buffer size during the Number of Locations to Program step (DQ7 is not valid in this condition). Write to an address in a sector different than the one specified during the Write-Buffer-Load command. Write an Address/Data pair to a different write-buffer-page than the one selected by the Starting Address during the write buffer data loading stage of the operation. Write data other than the Confirm Command after the specified number of data load cycles.

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 (BA)555h any time the device is ready to read array data. The system can read CFI information at the addresses given in Tables 12.3–12.6 within that bank. All reads outside of the CFI address range, within the bank, returns non-valid data. Reads from other banks are allowed, writes are not. To terminate reading CFI data, the system must write the reset command. The following is a C source code example of using the CFI Entry and Exit functions.
