SC92F84A2M20U from SOC(Shenzhen SinOne Microelectronics), in a SOP-20L. 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 power_in Positive supply pin; the datasheet gives an operating range of 2.4V to 5.5V, with 2.9V to 5.5V required above 12MHz.
2 P1.0/CMOD bidirectional General-purpose I/O P1.0, which doubles as CMOD, the touch-key external capacitor connection.
3 VSS power_in Ground reference pin for the device.
4 P1.1/INT01/TK22/RST bidirectional General-purpose I/O P1.1 with INT01 external interrupt input and TK22 touch channel; it is used as the external RST reset pin only when the Code Option DISRST is configured for reset.
5 P1.2/INT02/T0/RX0/TK21/tCK bidirectional General-purpose I/O P1.2 with INT02, T0 external counter input, RX0 UART0 receive, TK21 touch channel (avoid when using TK debug), and tCK programming/emulation clock.
6 P1.3/INT03/T1/TX0/TK20/tDIO bidirectional General-purpose I/O P1.3 with INT03, T1 external counter input, TX0 UART0 transmit, TK20 touch channel (avoid when using TK debug), and tDIO programming/emulation data.
7 P1.4/INT10/AIN9/TK19 bidirectional General-purpose I/O P1.4 with external interrupt INT10, ADC input channel AIN9 and touch channel TK19.
8 P1.5/INT11/AIN8/TK18 bidirectional General-purpose I/O P1.5 with external interrupt INT11, ADC input channel AIN8 and touch channel TK18.
9 P2.7/PWM5/AIN5/TK15 bidirectional General-purpose I/O P2.7 with PWM5 output, ADC input channel AIN5 and touch channel TK15.
10 P2.6/PWM4/AIN4/TK14 bidirectional General-purpose I/O P2.6 with PWM4 output, ADC input channel AIN4 and touch channel TK14.
11 P2.5/PWM3/AIN3/TK13 bidirectional General-purpose I/O P2.5 with PWM3 output, ADC input channel AIN3 and touch channel TK13.
12 P2.4/AIN2/TK12 bidirectional General-purpose I/O P2.4 with ADC input channel AIN2 and touch channel TK12.
13 P2.1/INT25/MISO/RX1/TK9 bidirectional General-purpose I/O P2.1 with INT25, SPI MISO, UART1 receive RX1 and touch channel TK9.
14 P2.0/INT24/MOSI/TX1/SDA/TK8 bidirectional General-purpose I/O P2.0 with INT24, SPI MOSI, UART1 transmit TX1, TWI SDA and touch channel TK8.
15 P0.5/INT21/SCK/TK5 bidirectional General-purpose I/O P0.5 with INT21, SPI/TWI clock SCK and touch channel TK5.
16 P0.4/INT20/COM4/TK4 bidirectional General-purpose I/O P0.4 with INT20, LCD common output COM4 and touch channel TK4.
17 P0.3/COM3/TK3 bidirectional General-purpose I/O P0.3 with LCD common output COM3 and touch channel TK3.
18 P0.2/PWM2/COM2/TK2 bidirectional General-purpose I/O P0.2 with PWM2 output, LCD common output COM2 and touch channel TK2.
19 P0.1/PWM1/COM1/TK1 bidirectional General-purpose I/O P0.1 with PWM1 output, LCD common output COM1 and touch channel TK1.
20 P0.0/PWM0/COM0/TK0 bidirectional General-purpose I/O P0.0 with PWM0 output, LCD common output COM0 and touch channel TK0.
