The AT49F010/HF010 1-Megabit (128K x 8) 5-volt Only CMOS Flash Memory is an in-system programmable and erasable Flash Memory manufactured by Atmel. Their 1-megabit of memory is organized as 131,072 words by 8 bits. Manufactured with Atmel's advanced nonvolatile CMOS technology, the devices offer access times to 45 ns (HF version) with a power dissipation of just 165 mW over the commercial temperature range. When the device is deselected, the CMOS standby current is less than 100 µA. To allow for simple in-system reprogrammability, the AT49F010/HF010 does not require high input voltages for programming. Five-volt-only commands determine the read and programming operation of the device. Reading data out of the device is similar to reading from an EPROM. Reprogramming the AT49F010/HF010 is performed by erasing the entire 1 megabit of memory and then programming on a byte by byte basis.
