Customer Case

GD32VF103 series MCU

GD32VF103 series MCU is the first RISC-V universal chip have been brought to scale in the world.

108MHz, 15% higher performance than M3 under the same conditions as GDF103
The maximum dynamic current (mA) is 50% lower than GDF103 which used the M3 processor, and the standby current (uA) is 25% lower than that.
Bumblebee processor, equivalent to N205
This MCU is equiped with complete program codebase and RISC-V software development platform.
