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 120 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.
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
the entire 1 megabit of memory and then programming on a byte by byte basis. The

Notes:
1. CE may be delayed up to tACC - tCE after the address transition without impact on tACC.
2. OE may be delayed up to tCE - tOE after the falling edge of CE without impact on tCE or by tACC - tOE after an address change
without impact on tACC.
3. tDF is specified from OE or CE whichever occurs frist (CL - 5 pF).
4. This parameter is characterized and is not 100% tested.
