8. Implementation Details
8.1 QSPI NOR flash
There is one QSPI NOR Flash on board. The device is Dialog AT25SF641B-MHB-T, 64 Mbit (8 Mbyte) in a
8-pad Ultra-Thin DFN (5 x 6 x 0.6mm) package. The QSPI port of RA4E1 is configured as Fast Read Dual
I/O mode on this kit.

8.2 PMOD
One PMOD type 2A/3A/6A connectors (2x6 pin, dual row, right angle socket) is included. If the RA4E1 SCI0
has been configured as Simple I2C, please insert a jumper on header J16 to route SDA signal to PMOD
connector pin 4 for meet PMOD 6A pin definition.
