New STM32C5 series: Sets new performance standards for cost sensitive designs

Come and see us at Embedded World this week: Hall 4A, Stand 148

embedded world 2026 - STMicroelectronics

Here is one of out latest highlights...

Time to set new performance standards for cost-sensitive devices in embedded applications while ensuring design simplicity in development.

Powered by an Arm® Cortex® M33 core and ST’s 40 nm flash platform, the STM32C5 series sets new performance standards for cost sensitive designs, redefining the DNA of entry level microcontrollers. Running at 144 MHz and delivering 593 CoreMark, it offers up to three times the performance of typical Cortex M0+ devices on the market.

It embeds up to 1024 Kbytes of flash and 256 Kbytes of SRAM, along with essential peripherals such as Ethernet, OctoSPI, and FDCAN. A wide package offer, from 20 to 144 pins, and support for temperatures up to 125°C make it suitable for a broad range of mainstream applications.

Crucially, the STM32C5 delivers enhanced performance and integration without impacting end product cost, offering exceptional value within cost sensitive designs.

    I think ST did quite good job on cost cutting entering cost. We need go back in time to understand. To era where LL did not exist, HAL was emerging, and main drivers were StdPeriph. Eclipse based STM32CubeIDE was Attolic True Studio back in time. It was best IDE for STM32 but it was paid. They worked on similar concept like Keil and IAR. ST acquired Attolic and made it free. Later they rebranded it to STM32CubeIDE.

    STM32CubeMX is getting an upgrade. A newer version named STM32CubeMX2 will be released soon.

    From official press release

    " Enhancements to the development ecosystem include a new STM32CubeMX flavor, STM32CubeMX2, which introduces a preview feature that allows faster access to reference code thereby accelerating development and easing code reuse. Also new in the STM32CubeC5 embedded software offer, the latest code-size optimized hardware abstraction layer (HAL2), gives access to all MCU features and allows more of the MCU’s memory to be used for application code.

    misaz Laughing Marketing speak. Joy I think it means that they hate the guy that came up with the idea of a free IDE.

    There are now two versions of the STM32CubeIDE - the newest one (2025) being for Visual Studio.  These MCUs work with both - according to the literature.

    Eliminating marketing bloat, seems like nice upgrade and modernisation of F1 family.

    I am curious what "First STM32 MCU to leverage the evolution of the STM332Cube ecosystem, always for free" mean?
