Description

The AT28HC64B 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 55 ns with power dissipation of just 220 mW. When the device is

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

The AT28HC64B 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
