Memory Array
To provide the greatest flexibility, the memory array of the Atmel
including a full chip erase. In addition, the array has been divided into physical sectors of uniform size, of which each sector
can be individually protected from program and erase operations. The size of the physical sectors is optimized for both code
and data storage applications, allowing both code and data segments to reside in their own isolated regions. The Memory
Architecture Diagram illustrates the breakdown of each erase level as well as the breakdown of each physical sector.
