... Commercial and Industrial Temperature Ranges Description The AT28BV16 is a low-power, high-performance Electrically Erasable and Program- mable Read Only Memory with easy to use features. The AT28BV16 is a 16K memory organized as 2,048 words by 8 bits. The device is manufactured with Atmel’s reliable nonvolatile CMOS technology. ...

Page 2

... The AT28BV16 is accessed like a static RAM for the read or write cycles without the need of external components. During a byte write, the address and data are latched inter- nally, freeing the microprocessor address and data bus for other operations. Following the initiation of a write cycle, the device will busy state and automatically clear and write the latched data using an internal control timer ...

... Device Operation READ: The AT28BV16 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 a high impedance state whenever high. This dual line control gives designers increased flexibility in preventing bus contention ...
