WCH Electronics' CH32V407 Packs Vector Extensions for a Speed Boost — Plus Optional PSRAM

WCH Electronics has launched a new entry in its popular CH32 family of 32-bit RISC-V architecture microcontrollers, the CH32V407 — expandable to include additional RAM as the CH32V467.

"CH32V407 is an industrial-grade interconnected microcontroller based on the QingKe RISC-V core," WCH Electronics says of the device. "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."

WCH's CH32 range has become popular among makers for offering high performance at a low cost, and uses the free and open source RISC-V instruction set architecture — though the particular implementation, QingKe, is proprietary. This latest CH32V407 part, brought to our attention by CNX Software, features a single 32-bit core running at up to 200MHz...
