... Three-volt-only commands determine the opera- tion of the device. Reading data out of the device is similar to reading from an EPROM. Reprogramming the AT29LV256 is performed on a sector basis; 64 bytes of data are loaded into the device and then simultaneously programmed. During a reprogram cycle, the address locations and 64 bytes of data are captured at microprocessor speed and internally latched, freeing the address and data bus for other operations ...

... Device Operation 4.1 Read The AT29LV256 is accessed like an EPROM. When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins is asserted on the outputs. The outputs are put in the high impedance state whenever high. This dual-line control gives designers flexibility in preventing bus contention ...

... Once a programming operation has been initiated, and for the duration of t 4.3 Hardware Data Protection Hardware features protect against inadvertent programs to the AT29LV256 in the following ways: (a) V power on delay – once V out 10 ms (typical) before programming; (c) Program inhibit – holding any one of OE low, CE high or WE high inhibits program cycles ...

... DATA Polling The AT29LV256 features DATA polling to indicate the end of a program cycle. During a pro- gram cycle an attempted read of the last byte loaded will result in the complement of the loaded data on I/O7. Once the program cycle has been completed, true data is valid on all out- puts and the next cycle may begin ...
