... 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 AT29LV512 is performed on a sector basis; 128 bytes of data are loaded into the device and then simultaneously programmed. ...

... Device Operation 4.1 Read The AT29LV512 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 ...

... DATA Polling The AT29LV512 features DATA polling to indicate the end of a program cycle. During a program 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 outputs and the next cycle may begin ...

... Toggle Bit In addition to DATA polling, the AT29LV512 provides another method for determining the end of a program or erase cycle. During a program or erase operation, successive attempts to read data from the device will result in I/O6 toggling between one and zero. Once the program cycle has completed, I/O6 will stop toggling and valid data will be read ...
