CH32V003 Mini Development Board Description
CH32V003 series is an industrial-grade general-purpose microcontroller designed based on QingKe RISC-V2Acore, which supports 48MHz system main frequency in the product function. The series features wide voltage,single line debug, low-power consumption and ultra-small package. It provides commonly used peripheralfunctions, built-in 1 group of DMA controller, 1 group of 10-bit analog-to-digital conversion ADC, 1 group ofop-amp comparator, multiple timers, standard communication interfaces such as USART, I2C, SPI, etc. The rated operating voltage of the product is 3.3V or 5V, and the operating temperature range is -40℃～85℃ industrial-grade.
QingKe V2 series microprocessor is a 32-bit general-purpose MCU based on the RISC-V instruction set (RV32I subset RV32E). It uses only 16 general-purpose registers and a streamlined structure optimized for deep embedded scenarios. The V2 series supports the RV32EC extension; the V2C variant adds hardware multiplication. Custom XW extensions include Hardware Prologue/Epilogue (HPE), Vector Table Free (VTF), a simplified 1-wire/2-wire serial debug interface (SDI), and support for the WFE instruction.
