Description
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.
