Description
The AT29LV020 is a 3-volt-only in-system Flash programmable and erasable read
only memory (PEROM). Its 2 megabits of memory is organized as 262,144 bytes by
8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device
offers access times to 200 ns with power dissipation of just 54 mW over the commer-
cial temperature range. When the device is deselected, the CMOS standby current is
less than 20
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 AT29LV020 does not require
high input voltages for programming. Five-volt-only commands determine the opera-
tion of the device. Reading data out of the device is similar to reading from an
