I2S Signals

The ATSAME54P20A has a built in two channel Inter-IC Sound Controller (I2S).

There is no on-board IC connected to this module, but the signals are available on the different pin-headers on the kit as shown in the table below.

Table 1. I2S Signals on SAM E54 Xplained Pro
Microcontroller Pin I2S Signal Pin-Header Location On-board Shared
PB16 SCK0 EXT2 pin 14  
PB17 MCK0 EXT2 pin 13  
PA20 FS0 Camera pin 121) SDCARD MCCDA
PA21 SDO Camera pin 111) SDCARD MCCK
PA22 SDI EXT1 pin 11 / Camera pin 101)  
PA23 FS1 EXT1 pin 12 / Camera pin 91)  
PB28 SCK1 EXT1 pin 15  
PB29 MCK1 EXT1 pin 17  
Info:

1) Soldering is required to connect these pins to the camera connector. The resistor footprint R205, R206, R207, and R208 have to be populated by 0-ohm resistors. The location of the footprints can be found in the Kit Modifications chapter.

Info: The I2S module can use more pins than listed in the table above. These signals are not listed in the table as they are shared with the on-board QSPI Flash and CAN transceiver.
