AI8G1K08-36I-SOP8

STC Micro · Microcontrollers (MCU/MPU/SOC) · SOP-8

AI8G1K08-36I-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 bidirectional I/O that is I/O at the factory and can be set through ISP as the active-low reset pin nRST, with alternate functions MCLKO (master clock output), INT2, T0, T1CLKO, RxD_3, MOSI and SCL_2.
2 Vcc power_in Power supply pin; the datasheet features list gives the operating voltage range as 1.9V to 5.5V.
3 P5.5 bidirectional Standard bidirectional I/O with alternate functions INT3, T1, T0CLKO, TxD_3 (UART1 transmit), SS (SPI slave select), and SDA_2 (I2C data).
4 Gnd power_in Ground pin.
5 P3.0 bidirectional Standard bidirectional I/O that is weak-pull-up/quasi-bidirectional after power-on, with alternate functions RxD (UART1 receive) and INT4; it is also the download/emulation interface pin.
6 P3.1 bidirectional Standard bidirectional I/O that is weak-pull-up/quasi-bidirectional after power-on, with alternate function TxD (UART1 transmit); it is also the download/emulation interface pin.
7 P3.2 bidirectional Standard bidirectional I/O with alternate functions INT0, SCLK (SPI clock), SCL (I2C clock) and RxD_2 (UART1 receive).
8 P3.3 bidirectional Standard bidirectional I/O with alternate functions INT1, MISO (SPI master input/slave output), SDA (I2C data) and TxD_2 (UART1 transmit).
