At this point you’ve heard of RISC-V and how fast the technology and ecosystem are expanding. But, given that the open-source ISA is still relatively new, there aren’t a ton of development kits out there that focus on RISC-V.
In comes the GD32V, a 32-bit general-purpose microcontroller that is based on the RISC-V core. It incorporates a 32-bit RISC-V processor core, which operates at a 108 MHz frequency with 128 Kilobytes of on-chip Flash, 32 Kilobytes of SRAM, and flash-access zero-wait states that allow data to be transferred immediately without having to wait for a clock cycle. The GD32V devices also integrate a single-cycle multiplier and multi-cycle hardware dividers in support of floating-point operations, and as many as 68 maskable peripheral interrupts that can be implemented at any of 16 priority levels.
