RISC-V is an open source instruction set architecture (ISA) based on the principle of Reduced Instruction Set (RISC). Compared to most instruction sets, the RISC-V instruction set can be freely used for any purpose, allowing anyone to design, manufacture, and sell RISC-V chips and software. The design of the RISC-V instruction set takes into account the reality of being small, fast, and low-power, but does not overly design specific microarchitectures.
Based on the thriving RISC-V open-source instruction set architecture, WCH optimizes and expands for low-power and high-speed response applications. It is equipped with free development tools such as IDE, exempting third-party kernel technology from licensing and commission fees. Through built-in and combined professional interface peripherals such as USB, PD, low-power Bluetooth, Ethernet, etc., WCH has built an MCU product line that not only has a global future ecosystem but also can be independently controlled and highly competitive in the long term.
