Description

Data Protection

The AT28BV64B 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

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

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