... When the device is deselected the standby current is less than 50 µA. The AT28BV64 is accessed like a Static RAM for the read or write cycles without the need for external components. During a byte write, the address and data are latched internally, freeing the microprocessor address and data bus for other operations. Fol- lowing the initiation of a write cycle, the device will busy state and automatically clear and write the latched data using an internal control timer ...

... Byte Write Writing data into the AT28BV64 is similar to writing into a Static RAM. A low pulse on the input with OE high and low (respectively) initiates a byte write. The address loca- tion is latched on the falling edge of WE (or CE); the new data is latched on the rising edge. ...
