STMicroelectronics STM32 microcontroller series

STMicroelectronics has launched a new generation of entry-level microcontrollers (MCUs) to boost the performance of tiny smart devices throughout factories, homes, cities and infrastructures while meeting cost, size and power limitations.

The new STM32C5 series is aimed at consumer and professional devices like smart thermostats, electronic door locks, industrial smart sensors, robotic actuators, wearable electronics and computer peripherals.

The STM32C5 microcontrollers feature an improved design based on ST’s proprietary 40 nm manufacturing process. This gives products more room to include modern features such as improved sensing, smoother control and enhanced user experiences — all while keeping dynamic power consumption low.

The MCUs also integrate built-in protections that help safeguard products against tampering and cyber risks. These security features support safer connected devices, a growing priority across consumer and industrial markets.

The new series of microcontrollers features an upgraded STM32Cube environment, now with size-optimised, production-grade drivers to leverage the many hardware features. The modernised ecosystem also introduces enhanced code generation and development tools as well as extended production-ready software examples.

The microcontrollers are now in production, targeting packages from 3 x 3 mm UFQFPN20 to 20 x 20 mm LQFP144. STM32 Nucleo evaluation boards, and a display extension board from Riverdi with TouchGFX development software for building entry-level graphical user interfaces, are ready to assist development.
