Features
Overview
•
•
•
•
The AVR architecture has two main memory spaces, the Program Memory and the Data Mem-
ory. In addition, the XMEGA D4 features an EEPROM Memory for non-volatile data storage. All
three memory spaces are linear and require no paging. The available memory size configura-
tions are shown in
memory signature row for calibration data, device identification, serial number etc.
Non-volatile memory spaces can be locked for further write or read/write operations. This pre-
vents unrestricted access to the application software.
