The GD32F330K8U6 is a 32-bit microcontroller that is part of the GD32 family of ARM microcontrollers from Gigadevice. It is based on the ARM Cortex-M0 processor core, which features 32KB SRAM, 128KB Flash memory, and powerful system resources such as I/O ports, Ethernet, multiple Timers and a 12-bit DAC, 10-bit ADC, and I2C/SPI interface. It can operate at frequencies up to 48MHz while consuming as little as 1.7mA/MHz in active mode. This makes it suitable for power- and cost-sensitive embedded applications in a wide range of industries. Other features include USB, CAN, DMA, Debugging, Smart Card Interface and Timer Capture.
