CH32V003F4U6 32-Bit - RISC-V 48MHz - 16KB Flash - Microcontroller IC - QFN-20

QingKe V2 series microprocessor is a 32-bit general-purpose MCU microprocessor based on the standard RISC-V instruction set RV32I subset RV32E, with only 16 general-purpose registers, half of RV32I, and a more streamlined structure for deep embedded scenarios. The V2 series supports standard RV32EC instruction extensions, with the V2C supporting hardware multiplication. In addition to custom XW extensions, Hardware Prologue/Epilogue (HPE), Vector Table Free (VTF), a more streamlined 1-wire/2-wire serial debug interface (SDI), and support for "WFE" instructions.
