Description
The AT49(H)BV010 and the AT49(H)LV010 are 3-volt-only, 1-megabit Flash memo-
ries organized as 131,072 words of 8 bits each. Manufactured with Atmel’s advanced
nonvolatile CMOS technology, the devices offer access times to 55 ns with power dis-
sipation of just 90 mW over the commercial temperature range. When the devices are
deselected, the CMOS standby current is less than 50
μ
A.
To allow for simple in-system reprogrammability, the AT49(H)BV/(H)LV010 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 AT49(H)BV/(H)LV010 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
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 number of program and erase cycles is in excess of 10,000 cycles.
