GD32F407 vs STM32F407: Cortex-M4 Replacement Comparison
GigaDevice positions the GD32F407 as an STM32F407-class alternative — both are 168 MHz Arm Cortex-M4 (with FPU/DSP) with aligned packages. It is a functional alternative (design-in), not a register-identical drop-in.
| Our pick GD32F407 GigaDevice | STM32F407 STMicroelectronics | |
|---|---|---|
| Core | Arm Cortex-M4 (FPU/DSP) | Arm Cortex-M4 (FPU/DSP) |
| Max clock | 168 MHz | 168 MHz |
| Package | LQFP100/144 / BGA | LQFP100/144 / BGA |
| Compatibility | Functional alternative, design-in | — |
| Porting | Recompile with GD32 lib, validate timing | — |
Which should you choose?
When the STM32F407 is short or needs replacing, the GD32F407 is a package-aligned same-class option; compare the pinout per package, recompile with the GD32 library, and validate clock/peripheral timing before mass production.

Frequently asked questions
Same performance as the STM32F407? ▾
Both are 168 MHz Cortex-M4 (with FPU/DSP) and positioned in the same class; but being cross-vendor, the device ID, clock tree, and some peripheral registers differ, so firmware must be re-validated with the GD32 library.
