Description
The AT29C1024 is a 5-volt-only in-system Flash programmable and erasable read
only memory (PEROM). Its 1 megabit of memory is organized as 65,536 words by 16
bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device
offers access times to 70 ns with power dissipation of just 330 mW. When the device
is deselected, the CMOS standby current is less than 200
µA.
The device endurance
is such that any sector can typically be written to in excess of 10,000 times.
