2 ? 2000 silicon storage technology, inc. 303-02 2/00 1 megabit page-mode eeprom sst29ee010a / sst29le010a / sst29ve010a data sheet 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 3). write the page-write to the sst29ee010a/29le010a/ 29ve010a uses the jedec standard software data protection (sdp) three-byte command sequence. 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 sst29ee010a/29le010a/29ve010a. 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 three-byte 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 t blco 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 4 and 5 for we# and ce# controlled page- write cycle timing diagrams and figures 13 and 15 for flowcharts. 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 se- quence that allows writing to the selected page and will leave the sst29ee010a/29le010a/29ve010a pro- tected 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 t blco time-out and the write timer operation. during the write operation, the only valid reads are data# polling and toggle bit. the page-write operation allows the loading of up to 128 bytes of data into the page buffer of the sst29ee010a/ 29le010a/29ve010a 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 page-write feature of sst29ee010a/ 29le010a/29ve010a allow the entire memory to be written in as little as 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. a 7 through a 16 . any byte not loaded with user data will be written to ff. see figures 4 and 5 for the page-write cycle timing diagrams. if after the completion of the three-byte sdp load sequence the host loads a byte into the page buffer within a byte-load cycle time (t blc ) of 100 s, the sst29ee010a/29le010a/29ve010a will stay in the page load cycle. additional bytes are then loaded con- secutively. the page load cycle will be terminated if no additional byte is loaded into the page buffer within 200 s (t blco ) from the last byte-load cycle, i.e., no sub- sequent 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. software chip-erase the sst29ee010a/29le010a/29ve010a provide a chip-erase operation, which allows the user to simulta- neously 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 se- quence, the device enters into an internally timed cycle similar to the write cycle. during the erase operation, the only valid read is toggle bit. see table 4 for the load sequence, figure 8 for timing diagram, and figure 17 for the flowchart.
