3.3 On-Board Memories

The SAMA7G5 MPU features a Universal DDR Memory Controller (UDDRC), a Quad Serial Peripheral Interface (QSPI) and a Secure Digital MultiMedia Card Controller (SDMMC) to enable interfacing to a wide range of external memories.

This section describes the memory devices mounted on the SAMA7G54-EK board:

• One 16-bit, 4-Gbit DDR3L SDRAM
• One 32-Gbit e.MMC NAND Flash
• One 1-Gbit Serial multi I/O Flash
• Two 2-Kb I²C serial EEPROMs with pre-programmed EUI-48 MAC ID

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.
