Microcontrollers

STMicroelectronics Microcontrollers contain a comprehensive range, starting from robust, low-cost 8-bit MCUs to 32-bit Arm®-based Cortex™-M3 Flash microcontrollers with a great choice of peripherals. ST has also extended this range to the ultra-low-power MCU platform EnergyLite™. Extensive support, through a combination of flexible and powerful development tools, training courses, consultancy, and web support, facilitates a faster time to market.
