WCH CH32V407 & CH32V467 EVB Board - RISC-V Vector Extension & Dual USB2.0 HS MCU Board
Overview
CH32V407 is an industrial-grade interconnected microcontroller based on the QingKe RISC-V core. It supports zero-wait operation at a 200MHz clock speed and the V-vector instruction set, making it suitable for applications such as accelerated computing and parallel processing. The CH32V407 integrates 2 sets of USB2.0 high-speed PHY transceivers (480Mbps), an Ethernet MAC controller, and 10/100Mbps physical layer transceivers; It features integrated analog resources such as dual ADCs, dual DACs, and OPAs; it also provides a wealth of peripheral resources, including 2 sets of DMA controllers (totaling 24 channels), SDIO, DVP interfaces, RNG,ARGB, LTDC, FSMC, multiple timer units, 10 USARTs, I2C interfaces, I3Cs, 3 SPIs, 2 I2Ss, and CAN interfaces.
The CH32V467 adds 4MB or 8MB of on-chip extended PSRAM memory to the CH32V407 and supports DMA.
