The GD32C2x1 series MCUs significantly enhance performance and peripheral specifications while maintaining excellent price competitiveness, achieving a substantial upgrade in cost-effectiveness. This series adopts Arm's advanced Cortex^®-M23 core architecture, delivering 10% higher performance than the Cortex^®-M0+ and reaching a main frequency of 48MHz. With efficient processing capabilities such as single-cycle multiplication and integer division operations, it greatly improves software execution efficiency.

In terms of memory configuration, it features 32KB~64KB of highly reliable embedded Flash and 12KB of low-power SRAM, with all memory areas equipped with ECC error correction. To meet the needs of diverse application scenarios, it offers multiple packaging options, including TSSOP20/LGA20, QFN28, LQFP32/QFN32, and LQFP48/QFN48.

The GD32C2x1 series MCUs provide up to four general-purpose 16-bit timers and one 16-bit advanced timer. It is equipped with two high-speed SPI interfaces (supporting four-wire QSPI mode at 24Mbps), two I2C interfaces (supporting Fast Mode+ at 1Mbit/s), and three UARTs (at 6Mbps), along with three DMA controllers and one I2S interface, ensuring high-efficiency communication.

It is particularly well-suited for applications such as small household appliances, white goods, BMS battery management systems, small display devices, portable consumer electronics, industrial auxiliary control systems, and automotive aftermarket equipment.
