The GD32E232 series MCUs provides up to four channels of 12-bit precision DAC outputs, eliminating the need for an external digital potentiometer, which reduces PCB size and BOM cost. The GD32E232 series MCUs also includes a built-in acceleration unit, along with the hardware multiplier and divider of the Cortex^®-M23 core. This allows the PWM duty cycle to be quickly calculated, enabling precise control of the DAC outputs.

In order to improve the accuracy of analog measurements, the GD32E232 series MCUs integrates a high performance 12-bit ADC with a 2.6MSPS sampling rate and up to 16 reusable channels. It also supports 16-bit hardware oversampling filtering and resolution configuration functions. The GD32E232's sampling accuracy surpasses that of similar products on the market.

The newly equipped Configurable Logic Array (CLA) provides more hardware flexibility for field applications and can implement simple combinational logic and sequential logic operations. This enhances CPU efficiency and improves the real-time performance of signal processing for cost-sensitive products.

The GD32E232 series MCUs enable the Cortex^®-M23 core to perform analog-intensive operations at up to 72 MHz and are equipped with additional standard peripheral resources for industrial applications, including: up to five 16-bit general-purpose timers, one 16-bit advanced vector control timer that supports three-phase PWM output, two 16-bit basic timers, and a multi-channel DMA controller. For serial interfaces, it includes two USARTs, two SPIs, two I2Cs, and one I2S.

The GD32E232 series MCUs operates from 1.8V to 3.6V power supply in a -40°C to + 105°C industrial temperature range and is available in QFN32 and QFN24 packages. Additionally, the GD32E232 series MCUs features a built-in I2C bootloader in a separate area of flash memory to meet the requirements for updating the program code in a small package and compact layout, Therefore, the existing standard I2C interface can be used directly to download programs and updates, providing a convenient solution for mass production.
