GigaDevice Releases GD32V RISC-V MCU and Development Boards

GD32VF103 RISC-V General Purpose MCU

A few years ago, we came across GigaDevice GD32 microcontroller compatible with STMicro STM32F103, but with a higher 108 MHz clock, and zero wait state internal flash. The MCU was also a drop-in replacement for the STMicro alternative since beside being software compatible, it was also pin-to-pin compatible. The company is now back with a new microcontroller, but it’s not Arm-based. Instead, GigaDevice GD32V is based on RISC-V open source architecture. GD32V General Purpose RISC-V MCU GigaDevice GD32V is a 32-bit RISC-V general-purpose MCU that targets industrial and consumer applications such as IoT, edge computing, artificial intelligence and “vertical industries”.

STMicro STM32 ARM Cortex M3 Boards List and Wiki

STMicro STM32 has popular Cortex-M micro-controller found in the $2 “Blue Pill” board, STMicro’s own Nucleo Board, as well as many other variants. Olavi Kamppari (OliviliK), working on hard real-time control with EmBitz IDE, has created a detailed Wiki for STMicro STM32 on Github with lots of information, including an interesting comparison table of various STM32 Cortex M3 boards (and one GD32 board). I’ve reproduced the table in his wiki below, made is sortable & filterable, and added links to Aliexpress store found in other parts of the wiki. You can find much more details about each board in the Wiki. Thanks to Zoobab for the tip. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011.

GigaDevice GD32 is a Faster, Software and Pin-to-pin STM32 Compatible Cortex M3 MCU

Las month, Olimex discovered a Chinese company called GigaDevice has made an STM32 clone called GD32 and compatible with STM32F103, but with higher core frequency (108MHz). Olimex has now posted an update after receiving a letter from GigaDevice, and trying GD32F103RBT6 MCU on their own STM32F103 boards. The company explained that GD32 was their own implementation, and claimed rights on GD32 trademarks, while Olimex discovered than GD32 was working just fine on their board having passed “all functional tests without any modifications”, and with all the same development tools and software code running fine. GD32F103xx datasheet (PDF / English version) can be downloaded to find a few more details: The GD32F103xx device incorporates the ARM Cortex-M3 32-bit processor core operating at 108 MHz frequency with Flash accesses zero wait states to obtain maximum efficiency. It provides up to 3 MB on-chip Flash memory and up to 96 KB SRAM memory. […]
