Both integrate a 10/100 Mbps Ethernet MAC + PHY, up to two USB 2.0 high-speed (480 Mbps) host/device PHYs, and support up to 8 MB on-chip PSRAM (CH32V467 only), targeting industrial IoT and edge AI/display applications. Six SKUs are available with varying GPIO counts (48-77), packages (LQFP64/QFN68/LQFP100), and optional FSMC. Documentation is mostly in Chinese for now, with MounRiver IDE as the current development option since the open-source ch32fun SDK doesn't yet support these chips. Packs of five CH32V467 units are available on AliExpress for roughly $2.4-2.9 per unit. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the difference between the WCH CH32V407 and CH32V467 microcontrollers? The CH32V467 adds 4MB or 8MB of on-chip PSRAM, which the CH32V407 lacks, making the CH32V467 better suited for display and HMI applications. Otherwise both chips share the same 200 MHz Qingke V3V RISC-V core, 200KB SRAM, 512KB Flash, built-in 10/100 Mbps Ethernet MAC and PHY, and up to two USB 2.0 high-speed host/device interfaces with integrated 480 Mbps PHY. _Track new RISC-V MCU releases like this one as you evaluate chips for embedded projects on daily.dev._ ### Does the WCH CH32V407 RISC-V microcontroller have built-in Ethernet? Yes, the CH32V407 includes a built-in 10/100 Mbps Ethernet MAC and PHY, so no external PHY chip is needed for networking. It also integrates a USB 2.0 high-speed host/device PHY supporting up to 480 Mbps, an LCD-TFT display controller, a 150 MHz digital video interface for cameras, and up to 77 GPIO pins across six SKU variants. _Compare integrated peripherals like Ethernet and USB PHYs on daily.dev when picking an MCU for IoT hardware._ ### Where can I buy the WCH CH32V467 microcontroller and how much does it cost? Packs of five CH32V467RET6 units sell for $12.15 and CH32V467VET6 units for $14.68 on AliExpress, working out to roughly $2.4 and $2.9 per unit respectively. The dedicated evaluation board for the CH32V407VET6, which includes an RJ45 jack and two USB 2.0 ports, was not found for sale at the time of the report. _Follow pricing and availability updates on niche RISC-V chips like this via daily.dev before sourcing hardware._ ## Similar posts on daily.dev -
