GD32F103RCT6 – ARM Cortex-M3 Microcontroller from GigaDevice

D32F103RCT6 is a 32-bit microcontroller from GigaDevice, based on the ARM Cortex-M3 core. It features high performance, a rich set of peripherals, and compatibility with the well-known STM32F103 from STMicroelectronics. Thanks to its higher clock speed (108 MHz instead of 72 MHz), larger RAM, and competitive pricing, it is a popular choice in embedded systems.

Key Features:

1. Processor & Performance – ARM Cortex-M3, up to 108 MHz.
2. Memory – 256 KB Flash, 48 KB RAM.
3. Interfaces – UART/USART, SPI, TWI, CAN, USB.
4. Timers & PWM – 16-bit Timers, advanced features (e.g., BLDC motor control), watchdog.
5. Signal Processing – 12-bit ADC, DAC.
6. Power & Parameters – 2.6V – 3.6V supply, power-saving modes, operating temperature from -40°C to +85°C.
7. Package – LQFP64, pin-compatible with STM32F103.
