Description
The AT29LV1024 is a 3-volt-only in-system Flash programmable and erasable read
only memory (PEROM). Its 1 megabit of memory is organized as 65,536 words by 16
bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device
offers access times to 150 ns with power dissipation of just 54 mW. When the device
is deselected, the CMOS standby current is less than 50 µA. The device endurance
is such that any sector can typically be written to in excess of 10,000 times.
To allow for simple in-system reprogrammability, the AT29LV1024 does not require
high input voltages for programming. Three-volt-only commands determine the opera-
tion of the device. Reading data out of the device is similar to reading from an
