Overview

The GD32 Low-Power MCU series delivers excellent power eﬃciency and optimized processing performance, with multiple operating and sleep modes. It integrates enhanced peripheral resources and offers flexible application support, enabling system-level power optimization.

This series is well suited for a wide range of applications, including industrial metering, compact consumer electronics, portable medical devices, battery management systems, and data acquisition and transmission systems.

Product Series

GD32L23x

The GD32L23x series MCU supports a system frequency of up to 64MHz, 64KB to 256KB embedded eFlash, 16KB to 32KB SRAM, and various enhanced I/O and peripheral resources connected to two APB buses. The GD32L23x series of MCUs achieve excellent power efficiency. The deep-sleep current is reduced to 1.8µA, the standby current is as low as 0.26µA. The new MCU is equipped with a wealth of peripheral interfaces to enhance connectivity, and the GPIO multiplexing rate is as high as 93%. It is well-suited for applications ranging from industrial meters, small consumer electronic devices, portable medical equipment, battery management systems, data acquisition and transmission.
