SC92F8370M08U from SOC Shenzhen SinOne Microelectronics, in a SOP-8. 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 | Power supply pin; the recommended operating voltage is 2.4 V to 5.5 V. |
| 2 | P1.0/CMOD | bidirectional | General-purpose I/O P1.0, which doubles as the CMOD pin for the external touch-key capacitor. |
| 3 | VSS | power_in | Ground reference pin. |
| 4 | P1.2/INT02/MISO/RX/T0/TK15/tCK | bidirectional | General-purpose I/O P1.2 that also carries external interrupt INT02, SPI MISO, UART RX, Timer0 external input T0, touch channel TK15 and the tCK programming/emulation clock; the datasheet advises avoiding TK15 if the TK debug function is used. |
| 5 | P1.3/INT03/MOSI/SDA/TX/T1/TK14/tDIO | bidirectional | General-purpose I/O P1.3 that also carries external interrupt INT03, SPI MOSI, TWI SDA, UART TX, Timer1 external input T1, touch channel TK14 and the tDIO programming/emulation data line; the datasheet advises avoiding TK14 if the TK debug function is used. |
| 6 | P2.1/INT25/TK7 | bidirectional | General-purpose I/O P2.1 that also carries external interrupt INT25 and touch channel TK7; all I/O pins support up to 50 mA sink current per the datasheet. |
| 7 | P2.0/INT24/TK6 | bidirectional | General-purpose I/O P2.0 that also carries external interrupt INT24 and touch channel TK6; all I/O pins support up to 50 mA sink current per the datasheet. |
| 8 | P0.1/PWM1/TK1 | bidirectional | General-purpose I/O P0.1 that also carries PWM1 output and touch channel TK1; P0 source drive strength is selectable in four levels. |
