Description

AT28BV256

The AT28BV256 is a high-performance Electrically Erasable and Programmable Read

Only Memory. Its 256K of memory is organized as 32,768 words by 8 bits. Manufac-

tured 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 200 µA.
