The XMEGA A3 has internal SRAM memory for data storage. The Memory Map for the devices
in the family resemble each other, see
The XMEGA A3 has internal EEPROM memory for non-volatile data storage. It is addressable
either in a separate data space or it can be memory mapped the normal data space. The
EEPROM memory supports both byte and page access.
The Internal SRAM and EEPROM memory spaces start at the same address in all devices, see
