The split-gate cell design and thickoxide tunneling injector attain better reliability and manufacturability compared with alternate approaches. The GLS29EE512 writes with a single power supply. Internal Erase/Program is transparent to the user. The GLS29EE512 conforms to JEDEC standard pin assignments for byte-wide memories. Featuring high performance Page-Write, the GLS29EE512 provides a typical Byte-Write time of 39 sec. The entire memory, i.e., 64 KByte, can be written page-by-page in as little as 2.5 seconds, when using interface features such as Toggle Bit or Data# Polling to indicate the completion of a Write cycle. To protect against inadvertent write, the GLS29EE512 have on-chip hardware and Software Data Protection schemes. Designed, manufactured, and tested for a wide spectrum of applications, the GLS29EE512 is offered with a guaranteed Page-Write endurance of 10,000 cycles. Data retention is rated at greater than 100 years. (c)2010 Greenliant Systems, Ltd. The GLS29EE512 is suited for applications that require convenient and economical updating of program, configuration, or data memory. For all system applications, the GLS29EE512 significantly improves performance and reliability, while lowering power consumption. The GLS29EE512 improves flexibility while lowering the cost for program, data, and configuration storage applications. To meet high density, surface mount requirements, the GLS29EE512 is offered in 32-lead PLCC and 32-lead TSOP packages. A 600-mil, 32-pin PDIP package is also available. See Figures 1, 2, and 3 for pin assignments. Device Operation The Greenliant Page-Write EEPROM offers in-circuit electrical write capability. The GLS29EE512 does not require separate Erase and Program operations. The internally timed Write cycle executes both erase and program transparently to the user. The GLS29EE512 has industry standard optional Software Data Protection, which Greenliant recommends always to be enabled. The GLS29EE512 is compatible with industry standard EEPROM pinouts and functionality. www.greenliant.com S71060-10-000 05/10 512 Kbit Page-Write EEPROM GLS29EE512 Data Sheet Read The Write operation has three functional cycles: the Software Data Protection load sequence, the page-load cycle, and the internal Write cycle. The Software Data Protection consists of a specific three-byte load sequence that allows writing to the selected page and will leave the GLS29EE512 protected at the end of the Page-Write. The page-load cycle consists of loading 1 to 128 Bytes of data into the page buffer. The internal Write cycle consists of the TBLCO time-out and the write timer operation. During the Write operation, the only valid reads are Data# Polling and Toggle Bit. The Read operations of the GLS29EE512 is controlled by CE# and OE#, both have to be low for the system to obtain data from the outputs. CE# is used for device selection. When CE# is high, the chip is deselected and only standby power is consumed. OE# is the output control and is used to gate data from the output pins. The data bus is in high impedance state when either CE# or OE# is high. Refer to the Read cycle timing diagram for further details (Figure 4). Write The Page-Write operation allows the loading of up to 128 Bytes of data into the page buffer of the GLS29EE512 before the initiation of the internal Write cycle. During the internal Write cycle, all the data in the page buffer is written simultaneously into the memory array. Hence, the PageWrite feature of GLS29EE512 allows the entire memory to be written in as little as 2.5 seconds. During the internal Write cycle, the host is free to perform additional tasks, such as to fetch data from other locations in the system to set up the write to the next page. In each Page-Write operation, all the bytes that are loaded into the page buffer must have the same page address, i.e. A7 through A16. Any byte not loaded with user data will be written to FFH. The Page-Write to the GLS29EE512 should always use the JEDEC Standard Software Data Protection (SDP) three-byte command sequence. The GLS29EE512 contains the optional JEDEC approved Software Data Protection scheme. Greenliant recommends that SDP always be enabled, thus, the description of the Write operations will be given using the SDP enabled format. The three-byte SDP Enable and SDP Write commands are identical; therefore, any time a SDP Write command is issued, Software Data Protection is automatically assured. The first time the three-byte SDP command is given, the device becomes SDP enabled. Subsequent issuance of the same command bypasses the data protection for the page being written. At the end of the desired Page-Write, the entire device remains protected. For additional descriptions, please see the application notes The Proper Use of JEDEC Standard Software Data Protection and Protecting Against Unintentional Writes When Using Single Power Supply Flash Memories. See Figures 5 and 6 for the Page-Write cycle timing diagrams. If after the completion of the three-byte SDP load sequence or the initial byte-load cycle, the host loads a second byte into the page buffer within a byte-load cycle time (TBLC) of 100 s, the GLS29EE512 will stay in the page-load cycle. Additional bytes are then loaded consecutively. The page-load cycle will be terminated if no additional byte is loaded into the page buffer within 200 s (TBLCO) from the last byte-load cycle, i.e., no subsequent WE# or CE# high-to-low transition after the last rising edge of WE# or CE#. Data in the page buffer can be changed by a subsequent byte-load cycle. The page-load period can continue indefinitely, as long as the host continues to load the device within the byte-load cycle time of 100 s. The page to be loaded is determined by the page address of the last byte loaded. The Write operation consists of three steps. Step 1 is the three-byte load sequence for Software Data Protection. Step 2 is the byte-load cycle to a page buffer of the GLS29EE512. Steps 1 and 2 use the same timing for both operations. Step 3 is an internally controlled Write cycle for writing the data loaded in the page buffer into the memory array for nonvolatile storage. During both the SDP threebyte load sequence and the byte-load cycle, the addresses are latched by the falling edge of either CE# or WE#, whichever occurs last. The data is latched by the rising edge of either CE# or WE#, whichever occurs first. The internal Write cycle is initiated by the TBLCO timer after the rising edge of WE# or CE#, whichever occurs first. The Write cycle, once initiated, will continue to completion, typically within 5 ms. See Figures 5 and 6 for WE# and CE# controlled Page-Write cycle timing diagrams and Figures 15 and 17 for flowcharts. (c)2010 Greenliant Systems, Ltd. Software Chip-Erase The GLS29EE512 provides a Chip-Erase operation, which allows the user to simultaneously clear the entire memory array to the "1" state. This is useful when the entire device must be quickly erased. The Software Chip-Erase operation is initiated by using a specific six-byte load sequence. After the load sequence, the device enters into an internally timed cycle similar to the 2 S71060-10-000 05/10 512 Kbit Page-Write EEPROM GLS29EE512 Data Sheet Data Protection Write cycle. During the Erase operation, the only valid read is Toggle Bit. See Table 4 for the load sequence, Figure 10 for timing diagram, and Figure 19 for the flowchart. The GLS29EE512 provide both hardware and software features to protect nonvolatile data from inadvertent writes. Write Operation Status Detection Hardware Data Protection The GLS29EE512 provides two software means to detect the completion of a Write cycle, in order to optimize the system Write cycle time. The software detection includes two status bits: Data# Polling (DQ7) and Toggle Bit (DQ6). The end of write detection mode is enabled after the rising WE# or CE# whichever occurs first, which initiates the internal Write cycle. Noise/Glitch Protection: A WE# or CE# pulse of less than 5 ns will not initiate a Write cycle. VDD Power Up/Down Detection: The Write operation is inhibited when VDD is less than 2.5V. Write Inhibit Mode: Forcing OE# low, CE# high, or WE# high will inhibit the Write operation. This prevents inadvertent writes during power-up or power-down. The actual completion of the nonvolatile write is asynchronous with the system; therefore, either a Data# Polling or Toggle Bit read may be simultaneous with the completion of the Write cycle. If this occurs, the system may possibly get an erroneous result, i.e., valid data may appear to conflict with either DQ7 or DQ6. In order to prevent spurious rejection, if an erroneous result occurs, the software routine should include a loop to read the accessed location an additional two (2) times. If both reads are valid, then the device has completed the Write cycle, otherwise the rejection is valid. Software Data Protection (SDP) The GLS29EE512 provides the JEDEC approved optional Software Data Protection scheme for all data alteration operations, i.e., Write and Chip-Erase. With this scheme, any Write operation requires the inclusion of a series of three byte-load operations to precede the data loading operation. The three-byte load sequence is used to initiate the Write cycle, providing optimal protection from inadvertent Write operations, e.g., during the system power-up or power-down. The GLS29EE512 is shipped with the Software Data Protection disabled. Data# Polling (DQ7) When the GLS29EE512 is in the internal Write cycle, any attempt to read DQ7 of the last byte loaded during the byteload cycle will receive the complement of the true data. Once the Write cycle is completed, DQ7 will show true data. Note that even though DQ7 may have valid data immediately following the completion of an internal Write operation, the remaining data outputs may still be invalid: valid data on the entire data bus will appear in subsequent successive Read cycles after an interval of 1 s. See Figure 7 for Data# Polling timing diagram and Figure 16 for a flowchart. The software protection scheme can be enabled by applying a three-byte sequence to the device, during a page-load cycle (Figures 5 and 6). The device will then be automatically set into the data protect mode. Any subsequent Write operation will require the preceding three-byte sequence. See Table 4 for the specific software command codes and Figures 5 and 6 for the timing diagrams. To set the device into the unprotected mode, a six-byte sequence is required. See Table 4 for the specific codes and Figure 9 for the timing diagram. If a Write is attempted while SDP is enabled the device will be in a non-accessible state for ~ 300 s. Greenliant recommends Software Data Protection always be enabled. See Figure 17 for flowcharts. Toggle Bit (DQ6) During the internal Write cycle, any consecutive attempts to read DQ6 will produce alternating `0's and `1's, i.e., toggling between 0 and 1. When the Write cycle is completed, the toggling will stop. The device is then ready for the next operation. See Figure 8 for Toggle Bit timing diagram and Figure 16 for a flowchart. The initial read of the Toggle Bit will typically be a "1". (c)2010 Greenliant Systems, Ltd. The GLS29EE512 Software Data Protection is a global command, protecting (or unprotecting) all pages in the entire memory array once enabled (or disabled). Therefore using SDP for a single Page-Write will enable SDP for the entire array. Single pages by themselves cannot be SDP enabled or disabled, although the page addressed during the SDP write will be written. 3 S71060-10-000 05/10 512 Kbit Page-Write EEPROM GLS29EE512 Data Sheet Single power supply reprogrammable nonvolatile memories may be unintentionally altered. Greenliant strongly recommends that Software Data Protection (SDP) always be enabled. The GLS29EE512 should be programmed using the SDP command sequence. Greenliant recommends the SDP Disable Command Sequence not be issued to the device prior to writing.
