Description
The AT49BV020 and the AT49LV020 are 3-volt-only, 2 megabit Flash memories
organized as 262,144 words of 8 bits each. Manufactured with Atmel's advanced non-
volatile CMOS technology, the devices offer access times to 70 ns with power dissipa-
tion of just 90 mW over the commercial temperature range. When the device is dese-
lected, the CMOS standby current is less than 50
μ
A.
To allow for simple in-system reprogrammability, the AT49BV/LV020 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 AT49BV/LV020 is performed by eras-
ing the entire 2 megabits of memory and then programming on a byte by byte basis.
The typical byte programming time is a fast 30
μ
s. 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 num-
ber of program and erase cycles is in excess of 10,000 cycles.
