GD32F405RGT6 Datasheet(PDF) - GigaDevice Semiconductor (HK) Limited

The processor frequency can reach 168MHz, and it provides a complete DSP instruction set, parallel computing capability and dedicated floating-point unit (FPU). GD32F405RGT6 integrates powerful computing performance and abundant external setting interfaces. Equipped with 512KB to 3072KB of large-capacity built-in flash memory and more than 192KB of SRAM. The kernel accesses the flash memory at high speed and zero wait, the highest main frequency. The next working performance can reach 210DMIPS. The chip uses 2.6V-3.6V power supply, and the I/O port can withstand 5V level. It has up to 8 16-bit general-purpose timers, 2 32-bit general-purpose timers, 2 16-bit basic timers and 2 8-channel DMA controllers.
