Description

The AT28C64B is a high-performance electrically-erasable and programmable read

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

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

access times to 150 ns with power dissipation of just 220 mW. When the device is

deselected, the CMOS standby current is less than 100 µA.
