Overview
The Atmel AVR architecture has two main memory spaces, the program memory and the data memory. Executable code
can reside only in the program memory, while data can be stored in the program memory and the data memory. The data
memory includes the internal SRAM, and EEPROM for nonvolatile data storage. All memory spaces are linear and
require no memory bank switching. Nonvolatile memory (NVM) spaces can be locked for further write and read/write
operations. This prevents unrestricted access to the application software.
A separate memory section contains the fuse bytes. These are used for configuring important system functions, and can
only be written by an external programmer.
The available memory size configurations are shown in “Ordering Information” on page 2. In addition, each device has a
Flash memory signature row for calibration data, device identification, serial number etc.
