1Pcs/Kit CH32V003F4P6 QingKe RISC-V2A 1-wire SDI System Main Frequency 48MHz

1. Overview

CH32V003 series is based on the QingKe RISC-V2A core design of industrial-grade general-purpose microcontroller, support 48MHz system main frequency, with wide voltage, 1-wire SDI, low-power consumption, ultra-small package, etc. CH32V003 series built-in a group of DMA controller, a group of 10-bit ADC, a group of OPA, multiple timers and standard communication interfaces USART, IC, SPI, etc.

The CH32V203 is an industrial-grade enhanced low-power general-purpose MCU based on 32-bit RISC-V core. The CH32V203 features high performance, and supports up to 144MHz system clock frequency. The operating power consumption can be as low as 45uA/MHz. CH32V203 integrates 2-channel USB interface which supports USB Host and USB Device functions. The CH32V203 provides 1-channel CAN interface (2.0B active), 2-channel OPA, 4 UARTs, 2 IICs, 12-bit ADC, 10-channel TouchKey and other peripheral resources. Several packages such as TSSOP20, QFN28 QFN48, LQFP32 and LQFP48 are available for users.

4. Introduction to use

The evaluation board can be debugged and downloaded online via WCH-LinkE. The SDI connection is shown below.

When using SDI mode for program downloading and debugging, 4 lines are generally used, power line VCC, ground line GND, data line SWDIO, clock line SWCLK. the evaluation board of CH32V003F4P6 should use WCH-LinkE for downloading and debugging, single-wire communication, only SWDIO is needed to connect PD1, SWCLK is not used.
