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-
