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.
