ESCOberon, an embedded variant of Oberon-2, is available for this MIT-licensed dev board as an alternative to C/C++ programming.

Norwegian-based Tenko has released an open-hardware development board based on STMicroelectronics’ STM32C5 microcontroller family. The compact board follows the familiar Blue Pill form factor while adding USB-C power, onboard USB-to-UART connectivity, and an alternative firmware environment based on Oberon-2. The board uses the recently introduced STM32C551CE, a 32-bit Arm Cortex-M33 microcontroller operating at up to […]

STMicroelectronics (NYSE: STM) has started volume deliveries of STM32 microcontrollers fully manufactured in China, produced by Huahong using 40nm eNVM technology. Initial mass production covers selected STM32H7 models, with STM32H5 and STM32C5 families planned for local mass production by end of 2026.The company says this establishes a fully localized STM32 supply chain in China—wafer manufacture, packaging, and testing—offering Chinese customers a dual-supply option with consistent global quality standards.

Not to be confused with the just-released STM32U3B5/C5 ultra-low-power MCUs, the entry-level STM32C5 Arm Cortex-M33 MCU family is designed for industrial sensors, smart home devices, electronic locks, thermostats, wearables, robotic actuators, and computer peripherals. The MCUs are manufactured using ST’s 40 nm flash process, clocked at up to 144 MHz, and feature 128 KB to 1 MB of flash and up to 256 KB of SRAM, with a dynamic power consumption of <80 µA/MHz. Key features include Ethernet, USB, OctoSPI, CAN bus, DMA, and various peripherals, including ADCs, comparators, and an op-amp. Security is also enhanced, with the series targeting SESIP3 and PSA Certified Level 3 through features such as side-channel attack-resistant crypto, Hardware Unique Keys (HUK), and a Coupling and Chaining Bridge (CCB) for secure key storage. STM32C5 key features and specifications: MCU core Arm Cortex-M33 32-bit CPU @ 144 MHz with single-precision FPU, DSP instructions, and MPU Up [...] The post STMicro STM32C5 entry-level, 144 MHz Cortex-M33 MCU features up to 1MB flash, 256KB SRAM, Ethernet, CAN Bus appeared first on CNX Software - Embedded Systems News.
