Overview

The GD32 Low-Power MCUs provide excellent power eﬃciency and optimized processing performance with multiple operating and sleep modes. They feature enhanced peripheral resources and application flexibility, paving the way for continuous optimization of system-level power consumption. The product series is well-suited for a wide range of applications, including industrial meters, small consumer electronic devices, portable medical equipment, battery management systems, data acquisition and transmission.

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.
