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 Supply Voltage – 2.6 to 3.6V Package – QFN36, LQFP48, …

Cypress PSoC 64 Microcontrollers Target Secure IoT Applications

PSoC 64 Secure MCU

If you are like me, you probably don’t remember, but back in 2017 Arm announced the Platform Security Architecture (PSA) that defines a set of requirements to secure low cost Internet of Things devices. There’s now at least on PSA compliant microcontroller, as Cypress Semiconductor introduced their PSoC 64 Secure MCU at Embedded World 2019 last month. The press release claims that PSoC 64 MCU family is one of “the first Arm Cortex-M processors to be certified as Level 1 compliant within the Arm Platform Security Architecture (PSA) certification scheme, PSA Certified, utilizing a secure Trusted Firmware-M (TF-M) implementation integrated into the Arm Mbed OS open-source embedded operating system”. PSoC 64 secure MCU key features and specifications: Arm Cortex-M4F core with 22‑µA/MHz active power consumption Optional Arm Cortex-M0+ core with 15‑µA/MHz power consumption System Memory – 160KB to 1MB SRAM Storage – 512KB to 2MB flash Security HW Cryptography – Symmetric: AES, 3DES; Asymmetric: RSA, ECC; Hashing: SHA-256, SHA-512;True Random …

GRiSP 2 Board Targets Embedded Erlang & Elixir Development (Crowdfunding)

Erlang is described as a programming language used to build massively scalable soft real-time systems with requirements on high availability, and used in telecoms, banking, e-commerce, computer telephony and instant messaging. Elixir is a dynamic, functional language designed for building scalable and maintainable applications that leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems. Elixir is used in many types of applications from higher-level web development to the embedded software domain, and Peer Stritzinger designed GRiSP board especially for the latter in 2017. He’s now back with GRiSP 2 featuring an NXP i.MX 6ULL SoM running Linux and RTEMS (Real-Time Executive for Multiprocessor Systems) RTOS.

Minnow Server is a Secure Web Server for Microcontrollers

Minnow Server Secure Websocket

Many embedded systems have a limited amount of memory, which would normally run programs with smaller footprints than on desktops or servers. For example, nginx and Apache2 are the common web servers, but on hardware with limited memory, smaller footprint web servers may be required, so that’s why I wrote a list of web servers for embedded systems running Linux/uClinux many years ago. But now, even platforms based on microcontrollers often need to run web server usually for configuration. We’ve already shown how to use Arduino to serve a simple web page and did the same in Getting Started with NodeMCU Board Powered by ESP8266 WiSoC but using Lua programming language instead. It may be more convenient to run a proper web server however, as it’s easier to change the interface, and we previously covered MicroWebSrv lightweight web server that works on platforms running MicroPython such as Pycom boards. Real Time Logic offers another open source alternative with their Minnow Server …
