STC8G1K17-36I-SOP8 from STC Micro, 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 | P5.4 | bidirectional | Standard I/O port P5.4 that can be set as the active-low reset input NRST, and also carries the MCLKO, SCL_2, MOSI, RxD_3, T0, INT2 and T1CLKO alternate functions. |
| 2 | Vcc | power_in | Power supply pin; the operating voltage range is 1.9V to 5.5V. |
| 3 | P5.5 | bidirectional | Standard I/O port P5.5 that also carries the INT3, T1, T0CLKO, TxD_3, SS and SDA_2 alternate functions. |
| 4 | Gnd | power_in | Ground pin. |
| 5 | P3.0 | bidirectional | Standard I/O port P3.0 that also serves as the UART1 receive pin RxD and external interrupt INT4; after power-up it is in weak-pull-up quasi-bidirectional mode. |
| 6 | P3.1 | bidirectional | Standard I/O port P3.1 that also serves as the UART1 transmit pin TxD; after power-up it is in weak-pull-up quasi-bidirectional mode. |
| 7 | P3.2 | bidirectional | Standard I/O port P3.2 that also serves as external interrupt INT0, SPI clock SCLK, I2C clock SCL and UART1 receive RxD_2. |
| 8 | P3.3 | bidirectional | Standard I/O port P3.3 that also serves as external interrupt INT1, SPI master-in MISO, I2C data SDA and UART1 transmit TxD_2. |
