Description

The AT49BV/LV1024A is a 3-volt only in-system Flash memory. The 1-megabit of

memory is organized as 65,536 words by 16 bits. Manufactured with Atmel’s

advanced nonvolatile CMOS technology, the devices offer access times to 45 ns with

power dissipation of just 72 mW over the industrial temperature range.

3-volt Only

Flash Memory

To allow for simple in-system reprogrammability, the AT49BV/LV1024A 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 simi-

lar to reading from an EPROM. Reprogramming the AT49BV/LV1024A is performed

by erasing a block of data (entire chip or main memory block) and then programming

on a word by word basis. The typical word programming time is a fast 20 µs. The end

of a program cycle can be optionally detected by the Data Polling feature. Once the

end of a word 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 word boot block section includes a reprogramming write lock out fea-

ture to provide data integrity. The boot sector is designed to contain user secure code,

and when the feature is enabled, the boot sector is permanently protected from being

erased or reprogrammed.
