Description

The AT29C010A is a 5-volt-only in-system Flash programmable and erasable read

only memory (PEROM). Its 1 megabit of memory is organized as 131,072 words by 8

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

offers access times to 70 ns with power dissipation of just 275 mW over the commer-

cial temperature range. When the device is deselected, the CMOS standby current is

less than 100

µA. The device endurance is such that any sector can typically be writ-

ten to in excess of 10,000 times.

To allow for simple in-system reprogrammability, the AT29C010A does not require

high input voltages for programming. Five-volt-only commands determine the opera-
