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 40
μ
A. The device endurance is such that any sector can typically be written
to in excess of 10,000 times.
