*NOTICE: Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

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 commercial temperature range. When the AT29LV020 is deselected, the CMOS standby current is less than 20 mA. 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 operation of the device. Reading data out of the device is similar to reading from an
