Memory Array
To provide the greatest flexibility, the memory array of the Atmel
granularity 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.
