Description

The AT49BV512 is a 3-volt only, 512K Flash memories organized as 65,536 words of

8 bits each. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the

devices offer access times to 70 ns with power dissipation of just 90 mW over the

commercial temperature range. When the devices are deselected, the CMOS standby

current is less than 50 µA.

AT49BV512

To allow for simple in-system reprogrammability, the AT49BV512 does not require

high input voltages for programming. Three-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 AT49BV512 is performed by erasing
