Industrial control, Consumer electronics, Communication equipment, Automotive electronics
The GD32F303CCT6 is an enhanced 32-bit microcontroller from GigaDevice featuring ARM Cortex-M4F core with DSP and FPU at 120 MHz. With 256KB Flash and 48KB SRAM in a compact LQFP-48 package, it balances performance and cost for embedded designs. The device offers rich peripherals including 3 USARTs, 2 I2C, 3 SPI, 2 I2S, CAN 2.0B, USB FS, and SDIO. Its 3 ADC units with 10 channels and 2 DAC units provide flexible analog integration. Ideal for motor control, industrial sensors, smart home devices, and compact IoT applications requiring Cortex-M4 performance in a small footprint.
The Cortex-M4F core with FPU enables hardware-accelerated floating-point operations and DSP instructions, delivering 152 DMIPS at 120MHz. The 256KB Flash memory with prefetch buffer and 48KB SRAM support efficient code execution. The clock system features internal RC oscillators and external crystal inputs with PLL multiplication. Peripherals are organized on APB1 and APB2 buses with DMA controller support for autonomous data transfers. The advanced control timer provides complementary PWM outputs with dead-time insertion, suitable for brushless DC motor control and switching power supplies.
