STC Micro · Microcontrollers (MCU/MPU/SOC) · SOP-8
STC15W204S-35I-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/RST/MCLKO/SS/CMP- | bidirectional | Standard I/O PORT5[4] that can be configured as the active-high reset input RST, the master-clock output MCLKO (internal R/C clock only on this series), or the comparator negative input CMP-, and must be set to high-impedance input when used as CMP-. |
| 2 | Vcc | power_in | Positive supply pin; the STC15W204S series operates from 2.5V to 5.5V. |
| 3 | P5.5/CMP+ | bidirectional | Standard I/O PORT5[5] that doubles as the comparator positive input CMP+, and must be set to high-impedance input when used as CMP+. |
| 4 | Gnd | power_in | Ground (negative supply) pin. |
| 5 | P3.0/RxD/INT4/T2CLKO | bidirectional | Standard I/O PORT3[0] that also serves as serial port 1 receive RxD, falling-edge-only external interrupt INT4 with power-down wake-up, and T2 clock output T2CLKO when enabled via INT_CLKO[2]. |
| 6 | P3.1/TxD/T2 | bidirectional | Standard I/O PORT3[1] that also serves as serial port 1 transmit TxD and the external count input for Timer/Counter 2 (T2). |
| 7 | P3.2/INT0 | bidirectional | Standard I/O PORT3[2] that also serves as external interrupt 0, which is rising- and falling-edge triggered unless IT0 is set (falling edge only), and supports power-down wake-up. |
| 8 | P3.3/INT1 | bidirectional | Standard I/O PORT3[3] that also serves as external interrupt 1, which is rising- and falling-edge triggered unless IT1 is set (falling edge only), and supports power-down wake-up. |
