GigaDevices GD32C231 Cortex MCU block diagram

Aimed at industrial use GD32C231, its “Cortex-M23 core architecture offers up to 10% higher performance than Cortex-M0+”, according to the company.

32 to 64kbyte of flash and 12kbyte or ram are available, all with error correction.

“An integrated hardware CRC module enhances data transmission integrity,” according to the company, which claimed: “These features ensure the MCU performs reliably in safety-critical environments such as industrial automation and automotive electronics.”

Operation is across 1.8 to 5.5V and -40 to +105°C, and ESD protection is to 8kV contact discharge or 15kV air discharge.

Deep sleep consumption can be 5μA, and wake from at least one sleep state takes 2.6μs. At full speed, it scores 3.74 CoreMark and consumed 93μA/MHz (~4.4mA).

Peripherals include a 12bit ADC with 13 external channels, two internal comparators, up to four general-purpose 16bit timers, one advanced 16bit timer (3phase PWM and deadbands), a quadrature encoder input, two SPI interfaces (including quad QSPI at 24Mbit/s), two I2C interfaces (1Mbit/s Fast Mode+), an I2S interface, three 6Mbit/s UARTs and a three=channel DMA.

Up to 45 GPIOs are available in the 48pad package options. The full list is: TSSOP20, LGA20, QFN28, LQFP32, QFN32, LQFP48 and QFN48.

. A complete SDK firmware package is also offered, featuring rich sample code and development board resources that cover everything from low-level drivers to advanced applications.

The company has a development environment called GD32 Embedded Builder that includes graphical configuration, and FreeRTOS is supported.

Then its ‘GD32 All-In-One Programmer’ is available to programme, erase, read and configure option bytes, and GD-Link debugger can operate though SWD and JTAG.

“Additionally, GD32C231 is compatible with toolchains including Arm Keil, IAR Embedded Workbench and SEGGER Embedded Studio,” said GigaDevice.

Use is expected in small home appliances, battery management systems, small-screen display devices, handheld consumer products, industrial auxiliary controls and automotive aftermarket products.

GigaDevice Semiconductor has its headquarters in Singapore, and has ISO26262:2018 automotive functional safety ASIL D certification, IEC 61508 functional safety product certification, as well as ISO9001, ISO14001, ISO45001, and Duns certifications.
