Description

The AT49F512 is a 5-volt-only in-system programmable and erasable Flash Memory.

Its 512K of memory is organized as 65,536 words by 8 bits. Manufactured with

Atmel’s advanced nonvolatile CMOS technology, the devices offer access times to 70

ns 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.

AT49F512

To allow for simple in-system reprogrammability, the AT49F512 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 AT49F512 is performed by erasing the

entire 512K of memory and then programming on a byte by byte basis. The typical

byte programming time is a fast 10 µs. The end of a program cycle can be optionally
