On 1st November 2018, GigaDevice Semiconductor officially released the GD32E230 series of Arm® Cortex®-M23 based MCUs bringing designers the advantages of small size, low cost, energy-efficiency and flexibility; while supporting security extension requirements to run the latest embedded application solutions.

As the first series of the GD32 MCU family based on the latest Cortex®-M23 core, the GD32E230 series MCUs are manufactured using the industry-leading 55nm low-power technology, focusing on ultra-low cost applications. With its small size and power efficiency, it can replace and enhance traditional 8-bit and 16-bit product solutions while delivering improved performance and power efficiency over the Arm® Cortex®-M0/M0+.

The GD32E230 MCU series provide 18 product types, including package options of LQFP48, LQFP32, QFN32, QFN28, TSSOP20 and QFN20 with a chip dimension from 7x7mm to 3x3mm giving designers unprecedented flexibility to respond to the rapid development of smart application challenges. The series is presently sampling and will officially move to mass production this month.

Brand-New architecture Arm® Cortex®-M23 Processor

Arm® Cortex®-M23 is the successor of the Arm® Cortex®-M0 and Cortex®-M0+ which is based on the latest Arm®v8-M architecture of embedded microprocessor cores. It adopts a Von Neumann two-stage pipelined structure and supports the complete Arm®v8-M reference instruction set while maximizing code compactness. Moreover, it is compatible with all Arm®v6-M instructions allowing engineers to easily transfer code from Arm® Cortex®-M0/M0+ processors to the Arm® Cortex®-M23. Additionally, the new Arm® Cortex®-M23 core is equipped with independent resources such as single-cycle hardware multipliers, hardware dividers, hardware frequency dividers, nested vectored interrupt controllers (NVICs), enhancing debug error correction and traceability for easier development. Subsequent products can also benefit from TrustZone® technology designed to support trusted and non-trusted software isolation and protection in hardware and to meet multiple security requirements.

 Brand-New generation GD32E230 products 

GD32E230 series products have a system frequency of up to 72MHz and are equipped with 16KB to 64KB of embedded flash memory and 4KB to 8KB of SRAM.  While running under the highest frequency, they can achieve a working performance of 55DMIPS and their CoreMark® test score can reach up to 154 points. Compared to the same frequency on a similar Cortex®-M0 and Cortex®-M0+ products, the code execution efficiency of the Cortex®-M23 is 40% higher and 30% higher respectively.

Not only does it have high-speed processing capacity, the new GD32E230 series products also provide many flexible interfaces to enhance connectivity. The chip is available with up to five 16-bit general- purpose timers, a 16-bit basic timer and a multi-channel controller, while the universal interface includes two USARTs, two SPIs, two I2Cs and an I2S. In addition, a 16-bit advanced timer that supports three-phase pulse width modulation PWM output and a Hall acquisition interface.   For signal conditioning, a high-speed rail-to-rail input/output analog voltage comparator and a 12-bit 2.6MSPS sampling rate high performance ADC with multi-channel high-speed data acquisition to support mixed-signal processing for motor control and industrial application requirements.

GD32E230 is powered by a 1.8V-3.6V wide supply voltage and the I/O ports are 5V-tolerant. The newly designed voltage domain supports power management targeting power-saving and low power consumption for portable applications with three power saving modes. The maximum operating current is only 118μA/MHz with all peripherals enabled at full-speed operation mode. While in deep-sleep mode, the current is reduced by 86% and the standby current is only 0.7μA when the battery is used to power the RTC. It also has 6KV ESD protection and excellent electromagnetic compatibility (EMS) capabilities to meet most industrial grade, high reliability and temperature standards. It is suitable for industrial automation, motor control, LED display, household appliances and electronic toys, smart cities and smart homes, electronic payments, electric vehicles, drones, robots and other applications. Furthermore, it maintains compatibility of software code and hardware pins to the awarded GD32F130/150 and GD32F330/350 series MCU. This allows users to easily switch between wide ranges of GD32 entry-level products, in order to achieve their development aspirations with great flexibility and ease of use.

GigaDevice Product Marketing Director Mr. Eric Jin said, “The GD32E230 series showcasing the brand-new Arm® Cortex®-M23 core microcontroller will give designers high performance while remaining economical for entry-level and mainstream applications. Also, GigaDevice is proud to bring China’s first Arm® Cortex®-M23 to the MCU world.  Focusing on the development blueprint of the brand-new core from analog peripheral enhancement to security enhancement, we will continue to bring more highly-valued experience to users with richer sets of capability in a complete development ecosystem.”
