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”. The new GD32VF103 series RISC-V MCU family features 14 models with the following key specifications: Core – GD32VF103 32-bit rv32imac RISC-V “Bumblebee Core” @ 108 MHz Memory – 8KB to 32KB SRAM Storage  – 16KB to 128KB flash Peripherals – USB OTG and CAN 2.0B I/O – 3.3V, 5V tolerant […]

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.
