Description

The AT49LV1024 and the AT49LV1025 are 3-volt only in-system Flash memories.

Their 1 megabit of memory is organized as 65,536 words by 16 bits. Manufactured

with Atmel鈥檚 advanced nonvolatile CMOS technology, the devices offer access times

to 55 ns with power dissipation of just 90 mW over the commercial temperature range.

The only difference between the AT49LV1024 and the AT49LV1025 is the package.

To allow for simple in-system reprogrammability, the AT49LV1024/1025 does not

require high input voltages for programming. Three-volt-only commands determine the

read and programming operation of the device. Reading data out of the device is simi-

lar to reading from an EPROM. Reprogramming the AT49LV1024/1025 is performed
