Description
The 64K x 32-bit cell is an embedded 2-Mbit Flash electrically erasable and programmable read only memory with a power supply of 1.8V ±10%. The memory is organized as 1024 pages of 64 32-bit words each. The device uses the Atmel ATC18 0.18 µm silicon process. For easy reprogrammability, it does not require a high input voltage for programming: the embedded Flash can be operated with a single 1.8V ±10% power supply.
