AT49BV512 General Description


The AT49BV512 is a 3-volt only, 512K Flash memories organized as 65,536 words of8 bits each. Manufactured with Atmel's advanced nonvolatile CMOS technology, thedevices offer access times to 70 ns with power dissipation of just 90 mW over thecommercial temperature range. When the devices are deselected, the CMOS standbycurrent is less than 50 µA.

To allow for simple in-system reprogrammability, the AT49BV512 does not requirehigh input voltages for programming. Three-volt only commands determine the readand programming operation of the device. Reading data out of the device is similar toreading from an EPROM. Reprogramming the AT49BV512 is performed by erasing
