| U1 | CH32V003 | CH32V003 series are industrial-grade general-purpose microcontrollers designed based on 32-bit RISC-V instruction set and architecture. It adopts QingKe V2A core, RV32EC instruction set, and supports 2 levels of interrupt nesting. The series are mounted with rich peripheral interfaces and function modules. Its internal organizational structure meets the low-cost and low-power embedded application scenarios. |
