Microcontrollers for IoT applications

MCUs make products smart by processing, analyzing and communicating data in order to generate control signals for the IoT device

Specifications for microcontrollers in IoT devices are as varied as the IoT applications themselves. Infineon’s microcontroller families provide the matching solutions, offering a broad variety of MCUs based on 32-bit Arm® architecture, Infineon’s 32-bit TriCore™ architecture, and others. These include microcontrollers in the XMC™ family and PSoC™ family that were custom-designed for IoT applications – from extremely energy-saving to extremely high-performance. The microcontrollers are backed up by an extensive portfolio of reliable, high-performance memories for embedded systems.



Comprehensive tools and development platforms simplify the development process, such as DAVE™, the development platform for XMC™ microcontrollers, AURIX™ embedded software, or AURIX™ tools. With the PSoC™ line of low-power, high-performance MCUs, at our portfolio, we make it even easier for our customers to enter the IoT arena. To evaluate and design with all available PSoC™ 6 MCUs, Infineon offers the ModusToolbox™ SW environment.  PSoC™ Creator is an integrated design environment that enables concurrent hardware and firmware editing, compiling and debugging of PSoC™ and FM0+ systems.
