5 Memories

The Atmel UC3-A3 XPLAINED has an external SDRAM memory mounted on the

board. There are also footprints available for adding either an industrial standard or a

proprietary Atmel DataFlash serial flash.

NOTE

The footprints share the same SPI lines including the chip select, and so it is not

possible to mount a device on both footprints at the same time.

Table 5-1. Compatible devices for the footprints.
