Description

The AT29LV1024 is a 3-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 150 ns with power dissipation of just 54 mW. When the device

is deselected, the CMOS standby current is less than 50

µA. The device endurance is
