Customer Case

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.
  • 166MHz, Customized security processor based on N205
  • Customize Lockstep, Bus parity, Memory ECC and other features
  • Mainly used in smart TVs, Smart-STB, smart speakers, etc.

China Mobile's first MCU chip based on RISC-V core


  • 144MHz, N308 core supports DSP, FPU, TEE, etc.
  • Encrypted memory (512KB on-chip Flash + 144KB on-chip SRAM)
  • Rich security features (built-in cryptographic algorithm hardware acceleration engine, TRNG, etc.)
  • Rich communication interfaces and high-performance analog interfaces
