Note:
- The package XCB (128-pin TQFP) has an exposed pad that is an additional ground. This must be soldered to the board's ground plane to provide additional noise immunity and thermal dissipation.
- All analog pin functions are on the peripheral function B. The peripheral function B must be selected to disable the digital control of the pin. The AC has analog signals on the peripheral function B and digital signals on the peripheral function M.
- Refer to the TCC Configuration Summary table for the list of supported features for each peripheral instance.
- I²C is not supported on all SERCOM pins. Refer to the SERCOM I²C Pinout table for the list of supported features for each peripheral instance.
- The following High-Sink pins have different properties than the regular pins: PA08, PA09, PA12, PA13, PA16, PA17, PA22, PA23, PD08, and PD09.

Note:
- The package XCB (128-pin TQFP) has an exposed pad that is an additional ground. This must be soldered to the board's ground plane to provide additional noise immunity and thermal dissipation.
- All analog pin functions are on the peripheral function B. The peripheral function B must be selected to disable the digital control of the pin. The AC has analog signals on the peripheral function B and digital signals on the peripheral function M.
- Five I/O pins (PB26, PB27, PB28, PB29 and PC04) are not connected as reserved for the HSM interconnection.
- Refer to the TCC Configuration Summary table for the list of supported features for each peripheral instance.
- I²C is not supported on all SERCOM pins. Refer to the SERCOM I²C Pinout table for the list of supported features for each peripheral instance.
- The following High-Sink pins have different properties than the regular pins: PA08, PA09, PA12, PA13, PA16, PA17, PA22, PA23, PD08, and PD09.
