Description

The AT28LV256 is a high-performance Electrically Erasable and Programmable

Read Only Memory. Its 256K of memory is organized as 32,768 words by 8 bits.

Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers

access times to 200 ns with power dissipation of just 54 mW. When the device is

deselected, the CMOS standby current is less than 200 µA.

The AT28LV256 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 of up to 64-bytes simultaneously. During a write cycle, the addresses and 1 to
