... WAIT states in high-performance microprocessor systems. The EN29LV040A has separate Output Enable ( OE ), Chip Enable ( CE ), and Write Enable (WE) controls, which eliminate bus contention issues. This device is designed to allow either single Sector or full chip erase operation, where each Sector can be individually protected against program/erase operations or temporarily unprotected to erase or program ...

... COMMAND DEFINITIONS The operations of the EN29LV040A are selected by one or more commands written into the command register to perform Read/Reset Memory, Read ID, Read Sector Protection, Program, Sector Erase, Chip Erase, Erase Suspend and Erase Resume. Commands are made up of data sequences written at specific addresses via the command register. ...
Page 10
... The system must write the reset command to exit the autoselect mode and return to reading array data. Programming Command Programming the EN29LV040A is performed by using a four bus-cycle operation (two unlock write cycles followed by the Program Setup command and Program Data Write cycle). When the program command is executed, no additional CPU controls or timings are necessary ...

... Another Erase Suspend command can be written after the device has resumed erasing. WRITE OPERATION STATUS DQ7: DATA Polling The EN29LV040A provides DATA Polling on DQ7 to indicate to the host system the status of the embedded operations. The DATA Polling feature is active during the embedded Programming, Sector Erase, Chip Erase, Erase Suspend. (See Table 6) When the embedded Programming is in progress, an attempt to read the device will produce the complement of the data last written to DQ7 ...
Page 12
... The flowchart for DATA Polling (DQ7) is shown on Flowchart 5. The DATA Polling (DQ7) timing diagram is shown in Figure 8. DQ6: Toggle Bit I The EN29LV040A provides a “Toggle Bit” on DQ6 to indicate to the host system the status of the embedded programming and erase operations. (See Table 6) During an embedded Program or Erase operation, successive attempts to read data from the device at any address (by toggling will result in DQ6 toggling between “ ...
