3.3 On-Board and External Memories

The SAMA7D6 Series MPU features a Universal DDR Memory Controller (UDDRC), one Quad Serial Peripheral Interface (QSPI), three Secure Digital MultiMedia Card Controllers (SDMMC), one octal SPI interface and one Static Memory Controller (SMC) to enable interfacing with a wide range of external memories. This section describes the memory devices mounted on the board:

  • One 16-bit, 8-Gbit DDR3L SDRAM
  • One 64-Mbit Serial quad I/O NOR Flash with preprogrammed EUI-48 MAC ID
  • One 4-Gbit SLC NAND Flash memory device
  • One 2-Kbit TWI EEPROM

Additional memory can be added to the board by:

  • installing an SD card in the SD card slot
  • using the USB ports

Support depends on the OS driver support.
