Description
The AT49F2048 is a 5-volt-only, 2 megabit Flash Memory organized as 128K words
of 16 bits each. Manufactured with Atmel's advanced nonvolatile CMOS technology,
the device offers access times to 70 ns with power dissipation of just 275 mW. When
deselected, the CMOS standby current is less than 300
μ
A.
To allow for simple in-system reprogrammability, the AT49F2048 does not require
high input voltages for programming. Five-volt-only commands determine the read
and programming operation of the device. Reading data out of the device is similar to
