SC92F7250M08U 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 | VSS | power_in | Ground reference pin (接地) for the device. |
| 2 | P1.2/INT02/T0/RX/tCK | bidirectional | General-purpose I/O also multiplexed as external interrupt INT02, Timer0 external counter input T0, UART receive RX, and the programming/emulation clock line tCK. |
| 3 | P1.3/INT03/T1/TX/tDIO | bidirectional | General-purpose I/O also multiplexed as external interrupt INT03, Timer1 external counter input T1, UART transmit TX, and the programming/emulation data line tDIO. |
| 4 | P2.7/PWM5/AIN7 | bidirectional | General-purpose I/O also multiplexed as PWM5 output and ADC input channel AIN7; setting EAIN7 makes the pin an ADC input and automatically removes its pull-up. |
| 5 | P2.6/PWM4/AIN6 | bidirectional | General-purpose I/O also multiplexed as PWM4 output and ADC input channel AIN6; setting EAIN6 makes the pin an ADC input and automatically removes its pull-up. |
| 6 | P2.1/INT25/AIN1 | bidirectional | General-purpose I/O also multiplexed as external interrupt INT25 input and ADC input channel AIN1; setting EAIN1 makes the pin an ADC input and automatically removes its pull-up. |
| 7 | P2.0/INT24/AIN0 | bidirectional | General-purpose I/O also multiplexed as external interrupt INT24 input and ADC input channel AIN0; setting EAIN0 makes the pin an ADC input and automatically removes its pull-up. |
| 8 | VDD | power_in | Positive supply pin; the datasheet gives an operating range of 2.4 V to 5.5 V (3.7 V to 5.5 V when running the 24 MHz system clock) and an absolute maximum of -0.3 V to 5.5 V. |
