Microcontrollers
Go from concept to design in less time with our 32-bit and 8-bit MCUs
Rapidly evaluate and prototype a wide variety of industrial and consumer devices using our low-power, fast speed microcontrollers, development kits, specialized example code (like energy monitoring, USB, LCD, touch sensors), and advanced debugging capabilities.
Our 32-bit MCUs enable high functioning, low-power systems by leveraging an EFM32™ ARM® Cortex®. While our EFM8™ 8051-based MCUs deliver the industry’s fastest speeds and lowest power.
