San Jose, USA (January 8, 2020) – GigaDevice, an industry-leading semiconductor supplier (SSE code: 603986), officially released the GD32E232 microcontroller series based on the Arm® Cortex®-M23 core. The series is presently sampling and will officially move to mass production in February.

This new series integrates on-chip memory, timers, data converters and many peripheral interfaces in a compact package. They are available in 4×4 mm and 3×3 mm packages and are particularly suitable for applications that require high precision measurement with long delays such as high-frequency pulse measurements, long pulse width waveform captures, or periodic signals that produce large interval delays.  These types of applications are seen in end equipment such as optical modules, photoelectric converters, fiber optic networks, base station systems, precision instruments, industrial control and automation systems.

Fully integrated control system 

The chip provides up to four channel 12-bit precision DAC outputs, eliminating the need for an external digital potentiometer, which can reduce PCB size and BOM cost. The GD32E232 also includes a built-in acceleration unit, along with the hardware multiplier &   divider of the Cortex®-M23 core. This allows the PWM duty cycle to be quickly calculated and the DAC outputs can be precisely controlled.

In order to improve the accuracy of the analog measurement, the chip integrates a 12-bit 2.6MSPS sampling rate high-performance ADC, with up to 16 reusable channels, while it supports 16-bit hardware oversampling filtering and resolution configuration function. The chip’s sampling accuracy is higher than 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. Furthermore, it helps to improve the working efficiency of the CPU and enhance the real-time performance of signal processing for cost-sensitive products.

These new highly integrated precision features are very useful for engineers of industrial control systems such as optical transceivers, optical modules, and access networks.  The GD32E232 series products can realize fully integrated digital control in such applications and can ensure precise control of optical drives and monitoring processes.

Main System Features

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

The MCU 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 MCU has a built-in I2C bootloader in a separate area of flash memory to meet the requirements of updating the program code in a small package and in a compact layout, Therefore, the existing standard I2C interface can be used directly to download programs and updates, providing a convenient solution for users in mass production.

GD32E23x series MCUs include GD32E230, GD32E231 and GD32E232 which consists of three series and 27 product models. All series are perfectly compatible in terms of software and pin packages, which makes it easier to implement code migration, expansion and upgrade, unleashing the full potential of the Cortex®-M23 core.
