The GD32E230xx device belongs to the value line of GD32 MCU family. It is a new 32-bit
general-purpose microcontroller based on the ARM Cortex-M23 core. The Cortex-M23
processor is an energy-efficient processor with a very low gate count. It is intended to be used
for microcontroller and deeply embedded applications that require an area-optimized
processor. The processor delivers high energy efficiency through a small but powerful
instruction set and extensively optimized design, providing high-end processing hardware
including a single-cycle multiplier and a 17-cycle divider.
