Pinout

Pin Name Type Function
1 ADC_CH4/DAC_OUT/P0.0 bidirectional GPIO P0.0 with ADC channel 4 input and 12-bit DAC output alternate functions. Software-enabled 10 kΩ pull-up to AVDD available.
2 RSTN/P0.2 bidirectional Active-low reset input (default function) or GPIO P0.2. Internal 100 kΩ pull-up to AVDD, always enabled; datasheet recommends an external 10 nF-100 nF cap to ground and an optional external 10 k-20 k pull-up.
3 AVSS power_in System (analog and digital) ground reference.
4 AVDD power_in Chip main power supply input, 2.2-5.5 V (3.0-5.5 V on B silicon). Requires a ≥1 µF decoupling capacitor placed as close to the pin as possible.
5 P3.2 bidirectional General-purpose I/O P3.2, no advertised alternate functions on this package.
