Internet of Things (IoT) microcontrollers are small, self-contained control units incorporated in a single integrated circuit (IC). They are widely used in smartphones, remote controls, office machines, medical devices, industrial equipment, warehouse inventory items, wearable devices, and home appliances. IoT microcontrollers require minimum programming, are easy to interface with external devices, and offer enhanced security. They are scaled-down computers that provide processing power, memory, and input and output peripherals. As a result, IoT microcontrollers find extensive applications across the consumer electronics, automotive, industrial, smart homes, and healthcare industries.

IoT Microcontroller Market Trends:

The increasing adoption of IoT connections across the globe, coupled with the rapid proliferation of smart devices, is one of the key factors favoring the market growth. IoT microcontroller is widely used in smartphones, wearables, thermostats, lights, speakers, and refrigerators due to their relative simplicity, increased inherent security, and minimal cost. Furthermore, the widespread product utilization in the automotive industry for connected vehicle technology that relies on sensors, antennas, communication devices, smart engine controls, and embedded software is providing a considerable boost to the market growth. Additionally, the integration of embedded non-volatile memory (eNVM) in IoT microcontrollers for high-end applications, as it helps lower power consumption and provides higher speed, better endurance, and increased efficiency, is creating a positive outlook for the market. Moreover, the rising product utilization for home and industrial automation, such as power tools, office machines, smart mirrors, heating systems, security alarms, smart meters, kitchen appliances, and entertainment systems, is providing an impetus to the market growth. Other factors, including significant advancements in the IoT technology, rising product utilization in the healthcare industry, rapid installation of smart meters to monitor overall electrical energy consumption, and increasing adoption of cloud, big data, and virtualization, are anticipated to drive the market growth.
