5.3.10 QSPI Flash

The SAM E54 Xplained Pro features one external MICRON, N25Q256A, 256Mbit QSPI NOR Flash

Memory. QSPI Flash access can be configured in the QSPI module in the SAM E54, with support for XIP

to run firmware directly from external flash. The table below lists all I/O-lines connected to the QSPI

Flash.

Info: The PCB tracks between the QSPI flash and the ATSAME54P20A are routed with 60Ω

impedance. The I/O drivers in the ATSAME54P20A should be set in high drive mode. The QSPI

flash I/O drive level can be configured to match 60Ω tracks in configuration registers in the QSPI

flash, refer to the QSPI datasheet for more information.
