PMS132B-S14 from PADAUK Tech, in a SOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD/AVDD power_in Positive supply: VDD for the digital core and AVDD for the ADC, bonded together internally and the same external pin; operating range 2.2V to 5.5V.
2 PA7/X1 bidirectional Port A bit 7 programmable input/output with weak pull-up, or crystal oscillator X1 pin; clear padier bit 7 when used for the crystal to reduce leakage.
3 PA6/X2 bidirectional Port A bit 6 programmable input/output with weak pull-up, or crystal oscillator X2 pin; clear padier bit 6 when used for the crystal to reduce leakage.
4 PB7/AD7/CIN5-/TM3PWM/PG1PWM bidirectional Port B bit 7 I/O with weak pull-up, ADC input channel 7, comparator negative input 5, Timer3 PWM output or PWMG1 output; clear pbdier bit 7 when used as analog input.
5 PB3/AD3/PG2PWM bidirectional Port B bit 4 I/O with weak pull-up, ADC input channel 4, Timer2 PWM output or PWMG0 output; clear pbdier bit 4 when used as analog input.
6 PB5/AD5/INT0A/TM3PWM/PG0PWM bidirectional Port B bit 5 I/O with weak pull-up, ADC input channel 5, external interrupt 0A (rising and falling edge), Timer3 PWM output or PWMG0 output; clear pbdier bit 5 when used as analog input.
7 PA5/PRSTB/PG2PWM bidirectional Port A bit 5 input or open-drain output with no pull-up or pull-down resistor, hardware reset input PRSTB, or PWMG2 output; a 33 ohm series resistor is advised when used as input in noisy systems.
8 PB0/AD0/INT1 bidirectional Port B bit 0 I/O with weak pull-up, ADC input channel 0 or external interrupt 1 (rising and falling edge); clear pbdier bit 0 when used as analog input.
9 PB1/AD1/Vref bidirectional Port B bit 1 I/O with weak pull-up, ADC input channel 1 or ADC external high reference voltage; clear pbdier bit 1 when used as analog input.
10 PB3/AD3/PG2PWM bidirectional Port B bit 3 I/O with weak pull-up, ADC input channel 3 or PWMG2 output; clear pbdier bit 3 when used as analog input.
11 PA3/AD8/CIN0-/TW2PWM/PG2PWM bidirectional Port A bit 3 I/O with weak pull-up, ADC input channel 8, comparator negative input 0, Timer2 PWM output or PWMG2 output; clear padier bit 3 when used as analog input.
12 PA4/AD9/CIN+/CIN-/INT1A/PG1PWM bidirectional Port A bit 4 I/O with weak pull-up, ADC input channel 9, comparator positive or negative input 1, external interrupt 1A or PWMG1 output; clear padier bit 4 when used as analog input.
13 PA0/AD10/CO/INT0/PG0PWM bidirectional Port A bit 0 I/O with weak pull-up, ADC input channel 10, comparator output, PWMG0 output or external interrupt 0 (rising and falling edge).
14 GND/AGND power_in Ground: GND for the digital core and AGND for the ADC, bonded together internally and the same external pin.
