Description

The AT29LV010A is a 3-volt-only in-system Flash programmable and erasable read

only memory (Flash). Its 1 megabit of memory is organized as 131,072 bytes by 8 bits.

Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers

access times to 150 ns with power dissipation of just 54 mW over the commercial

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 AT29LV010A 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

EPROM. Reprogramming the AT29LV010A is performed on a sector basis; 128-bytes

of data are loaded into the device and then simultaneously programmed.
