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.

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 typical byte programming time is a fast 30 µs. The end of a program cycle can be optionally detected by the DATA polling feature. Once the end of a byte program 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. The optional 8K bytes boot block section includes a reprogramming write lock out feature to provide data integrity.

AT49BV512 BOOT BLOCK PROGRAMMING LOCKOUT: The device has one designated block that has a programming lockout feature. This feature prevents programming of data in the designated block once the feature has been enabled. The size of the block is 8K bytes. This block, referred to as the boot block, can contain secure code that is used to bring up the system. Enabling the lockout feature will allow the boot code to stay in the device while data in the rest of the device is updated.
