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 µA.

AT49F2048

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
