WCH Launches a Sub-10¢ RISC-V Microcontroller, While a $6.90 Dev Board Gets You Started | Gareth Halfacree,

Designed for less-computationally-demanding workloads, this 32-bit RISC-V chip is priced extremely aggressively.

WCH Electronics has launched a new, low-cost RISC-V microcontroller chip running at up to 48MHz and which is priced in volume at less than 10¢ per unit — and the first development board to feature the part has already hit the market.

Based on an implementation of RV32, the 32-bit version of the free and open source RISC-V architecture, which the company is calling ‘RISC-V2A”, the WCH CH32V003 family offers a clock speed up to 48MHz, 2kB of static RAM (SRAM), 16kB of flash storage, and between six and 18 interrupt-capable general-purpose input/output (GPIO) pins with one USART, one I2C, and one SPI bus plus up to eight channels of 10-bit analog to digital conversion (ADC).
