Specifications

The AT49F010/HF010 are 5-volt-only in-system programmable and erasable Flash Memories. Their 1-megabit of memory is organized as 131,072 words by 8 bits. Manu- factured with Atmel's advanced nonvolatile CMOS technology, the devices offer ac-cess 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 A. 

To allow for simple in-system reprogrammability, the AT49F010/HF010 does not re- quire 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 per- formed by erasing the entire 1 megabit of memory and then programming on a byte by byte basis. The byte programming time is a fast 50 s.  The end of a program cycle can be optionally detected by the DATA polling feature. Once the end of a byte pro-gram cycle has been detected, a new access for a read or program can begin. The typical number of program and erase cycles is in excess of 10,000 cycles.
