WCH CH32V407/467 RISC-V MCU integrates Fast Ethernet MAC + PHY, 480 Mbps USB 2.0 PHY, up to 8 MB on-chip PSRAM

WCH released the CH32V407 and CH32V467 RISC-V microcontrollers, featuring a 200 MHz QingKe V3V core with RVV vector extensions, integrated 10/100 Mbps Ethernet MAC + PHY, a USB 2.0 high-speed (480 Mbps) host PHY, and up to 8 MB on-chip PSRAM (CH32V467 only), targeting industrial IoT and edge AI applications. The CH32V467 offers 4 MB or 8 MB PSRAM for display/HMI use, while both MCUs deliver 4.11 CoreMark/MHz, outperforming typical Arm Cortex-M4 cores.

WCH CH32V407 and CH32V467 are new 200 MHz RISC-V microcontrollers with a built-in 10/100 Mbps Ethernet MAC + PHY, a USB 2.0 high-speed 480 Mbps host PHY, up to 8 MB on-chip PSRAM, and a range of peripherals for industrial IoT & edge AI applications. Both are based on the company’s Qingke V3V core with RVV vector extensions, delivering 4.11 CoreMark/MHz, a score higher than a typical Arm Cortex-M4 core. The main difference between the CH32V407 and CH32V467 is that the latter comes with 4 MB or 8 MB PSRAM, making it more suitable for display/HMI applications. WCH CH32V407/467 specifications: MCU Core – QingKe V3V 32-bit RISC-V IMACV-X, X = custom core @ up to 200 MHz RVV-vector instruction set and parallel computing Memory and storage 200KB SRAM 4MB or 8MB PSRAM memory CH32V467 only 512KB Flash SDIO Interface MMC, SD/SDIO Cards, and CE-ATA Optional Flexible Static Memory Controller FSMC ...
