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.
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.
