... Commercial and Industrial Temperature Ranges 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 with power dissipation of just 330 mW. When the device is deselected, the CMOS standby current is less than 200 A ...
