GD32L233KBQ6

General description

The GD32L233xx 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 CortexM23 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 areaoptimized 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.

The GD32L233xx device incorporates the ARM® Cortex®-M23 32-bit processor core 

operating at up to 64 MHz frequency with Flash accesses 0~3 wait states to obtain 

maximum efficiency. It provides up to 256 KB embedded Flash memory and up to 32 KB 

SRAM memory. An extensive range of enhanced I/Os and peripherals connected to two 

APB buses. The devices offer one 12-bit ADC and two comparators, up to four general 

16-bit timers, two basic timers, and a 32-bit low power timer, as well as standard and 

advanced communication interfaces: up to two SPIs, three I2Cs, two USARTs, two 

UARTs, an I2S, and an LPUART.

The device operates from a 1.71 to 3.63 V power supply and available in -40 to +85 °C 

temperature range. Several power saving modes provide the flexibility for maximum 

optimization between wakeup latency and power consumption, an especially important 

consideration in low power applications.

The above features make the GD32L233xx devices suitable for a wide range of 

applications, especially in areas such as industrial control, motor drives, user interface, 

power monitor and alarm systems, consumer and handheld equipment, gaming and GPS, 

E-bike and so on.
