Memories

The UC3-A3 Xplained does not have any external memories mounted on the board. Footprints are available for adding either an industrial standard or an Atmel proprietary serial Dataflash^®.

Note: The footprints share the same SPI lines including the chip select, and it is therefore not possible to mount a device on both footprints at the same time.
