Description

The AT49BV/LV2048B is a 3-volt only in-system Flash memory. The 2 megabits of

memory is organized as 131,072 words by 16 bits. Manufactured with Atmel’s

advanced nonvolatile CMOS technology, the device offers access times to 45 ns with

power dissipation of just 90 mW over the commercial temperature range.

To allow for simple in-system reprogrammability, the AT49BV/LV2048B 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/LV2048B 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 30 µs. The end

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

end of a 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.
