The Atmel XMEGA-A3BU Xplained has an Atmel AT45DB642D
DataFlash device mounted. A footprint is also available for adding an industrial standard
serial flash like the AT25 series from Atmel. Compatible serial flash devices for both
footprints are listed in
Table 1 and the connection to the MCU is shown in
Table 2.
Note:
The footprints share the same SPI lines including
the chip select, and therefore it is not possible to mount devices on both footprints
at the same time.
