Description

The AT28LV64B is a high-performance electrically erasable programmable read only

memory (EEPROM). Its 64K of memory is organized as 8,192 words by 8 bits. Manu-

factured with Atmel’s advanced nonvolatile CMOS technology, the device offers ac-

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

lected, the CMOS standby current is less than 20 µA.

The AT28LV64B 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
