EN29LV800 Summary of contents
Page 1
... The EN29LV800 features 3.0V voltage read and write operation, with access times as fast as 55ns to eliminate the need for WAIT states in high-performance microprocessor systems. The EN29LV800 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 EN29LV800 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. ...

... Word / Byte Programming Command The device may be programmed by byte or by word, depending on the state of the Byte# Pin. Programming the EN29LV800 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 ...
