... When the device is deselected, the CMOS standby current is less than 20 µA. The AT28BV64B is accessed like a static RAM for the read or write cycle without the need for external components. The device contains a 64 byte page register to allow writing bytes simultaneously ...

... Read The AT28BV64B is accessed like a static RAM. 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 when either high. This dual-line control gives designers flexibility in preventing bus contention in their systems ...

... DATA Polling The AT28BV64B features DATA Polling to indicate the end of a write cycle. During a byte or page write cycle an attempted read of the last byte written will result in the complement of the written data to be presented on I/O7. Once the write cycle has been completed, true data is valid on all outputs, and the next write cycle may begin ...
