STM32C0 is a 32-bit microcontroller (MCU) for cost-sensitive applications. It is a sub-family of the STM32 microcontroller family developed by STMicroelectronics. It specifically targets low-power and cost-sensitive applications, such as consumer and industrial control, automotive, and security. The STM32C0 microcontrollers feature an Arm Cortex-M0+ core, low power consumption, and a wide range of peripheral options for various applications. The STM32C0 series is suitable for use in equipment like home appliances, industrial pumps, fans, and smoke detectors, typically served by simpler 8-bit and 16-bit MCUs.

The modern, 32-bit design of the STM32C0 permits improvements such as faster response, extra functions, and network connection at similar overall cost and power consumption. The STM32C0 family is simple to use and offers a free and extensive support ecosystem with resources including tools, software packs, and the chance to connect with various developer communities to ease entry to the 32-bit world for new users.

The new STM32C0 series MCUs come in small and economical packages. To increase the number of I/O pins, the MCU features only a single pair of external power connections. Moreover, the MCU offers an onboard, high-accuracy (1%) clock that saves external timing components, thus reducing the BoM.

According to the company, as a part of the STM32 continuum, STM32C0 devices allow easy migration into the STM32G0 Series to tackle more demanding projects, sharing a consistent pinout. The STM32C0 series integrates up-to-date peripherals, including a 1.7 MSPS analogue-digital converter (ADC) with hardware for 16-bit over-sampling multiple timers including an advanced control timer for applications like motor control.

“The next generations of smart appliances and industrial controllers must be easy to use, ultra-competitively priced, and with assured supply,” said Daniel Colonna, STM32 Marketing Director at STMicroelectronics. “By delivering on these requirements, our new STM32C0 general-purpose entry-level MCUs introduce exciting options to the 8-/16-bit applications space, with the added benefits that come with the broad and powerful STM32 ecosystem.”
