Why GD32 MCUs Go Out of Stock — And What to Order Instead
GigaDevice's GD32 series became the go-to STM32 alternative during global MCU shortages. That success created its own supply challenges.
Demand Drivers
- STM32 pin-compatibility — Engineers designed GD32 in as drop-in replacements
- Price advantage — 20-40% lower unit cost at volume
- Domestic China preference — Some OEMs mandated local MCU suppliers
Current Availability
GD32F303CCT6 remains our most-quoted GD32 part. Lead times have stabilized to 1-2 days for standard quantities, though high-volume orders (10K+) may require 2-3 week factory lead times.
Alternatives When GD32 Is Unavailable
| If you need | Consider | |-------------|----------| | Pin-compatible M3 | STM32F103C8T6 | | More performance | STM32F407VGT6 | | Lower cost new design | RP2040 |
Submit your BOM for real-time availability across all three options.
