Pinout

Pin Name Type Function
1 GPIO22/EQEP1S/LINTXA bidirectional GPIO22 (alternates: EQEP1 strobe I/O, LIN transmit output); internal pull-up is enabled after reset and inputs are not 5 V tolerant.

5 VDD power_in CPU and logic digital supply; with the internal VREG enabled a 1.2 µF (minimum) capacitor is required at each VDD pin, and an external 1.71 V to 1.995 V supply is used only when the VREG is disabled.
6 VSS power_in Digital ground pin.
7 XRS bidirectional Device reset input and watchdog reset output, open-drain with internal pull-up; a 2.2 kΩ to 10 kΩ resistor between XRS and VDDIO is required and any external noise filter capacitor should be 100 nF or less.
8 TRST input JTAG test reset with internal pull-down that must be held low during normal device operation, with an external pull-up (typically 2.2 kΩ) recommended.
9 ADCINA7 input ADC group A channel 7 analog input with a 0 V to 3.3 V full-scale range when using the internal reference.
10 ADCINA6/COMP3A/AIO6 input ADC group A channel 6 analog input, also comparator 3A input and digital AIO6 (AIO pins have no internal pull-up).
