CH32V003J4M6

WCH Jiangsu Qin Heng · Microcontrollers (MCU/MPU/SOC) · SOP-8

CH32V003J4M6 from WCH Jiangsu Qin Heng, 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 PD6 bidirectional I/O/A pin whose default function is PD6, with URX/A6 as its default multiplexed functions (A6 is ADC input channel 6) and T2CH3_3/UTX_2 as remap options.
2 VSS power_in Ground reference; the datasheet states all voltages are referenced to VSS.
3 PA2 bidirectional I/O/A pin whose default function is PA2, with A0/OPP0 and OSCO/T1CH2N as default multiplexed functions (A0 is ADC input channel 0).
4 VDD power_in Supply pin: VDD = 2.7 to 5.5 V powers the I/O pins and the internal regulator, and the datasheet notes ADC performance degrades below 2.9 V.
5 PC1 bidirectional 5 V-tolerant (FT) I/O whose default function is SDA/NSS, with URX_3 and T1BKIN_1/T2CH4_1 among its remap options.
6 PC2 bidirectional 5 V-tolerant (FT) I/O whose default function is SCL/URTS/T1BKIN, with AETR_1 and T2CH2_1 among its remap options.
7 PC4 bidirectional I/O/A pin whose default function is PC4, with T1CH4/MCO and A2 (ADC input channel 2) as default multiplexed functions.
8 PD1 bidirectional I/O/A pin whose default function is PD1 with SWIO (single-wire debug interface) as a default multiplexed function, plus T1CH3N and AETR2 alternates.
