QingKe V4 series microprocessor manual,QingKe V4 series microprocessors are self-developed 32-bit general-purpose MCU microprocessors based on the standard RISC-V Instruction Set Architecture (ISA). According to different application scenarios and instruction set combinations, the series includes V4A, V4B, V4C, V4F. V4 series all support RV32IMAC instruction set extensions, among which V4F supports single-precision hardware floating-point, i.e. RV32IMACF extensions. In addition, they also support Hardware Prologue/Epilogue (HPE), Vector Table Free (VTF), a streamlined 2-wire serial debug interface (SDI), support for "WFE" instructions, Physical Memory Protection (PMP), and other features.
