Market Growth Factors

Microcontrollers are a key component of Internet of things (IoT) devices that send and receive data to control systems in their environment. IoT devices are proliferating, deployed in billions of units across healthcare, transportation, and consumer appliances. Microcontrollers as the "brains" to control sensors, perform processing, and provide connectivity in these networks have driven the demand for these products.

The automotive industry faces a sea change as vehicles are electrified, automated, and connected. Automotive subsystems that use microcontrollers include anti-lock braking system, airbags, infotainment, and advanced driver-assistance system (ADAS). With the transition towards autonomous cars, which requires real-time data processing, navigation, steering and safety, microcontrollers are expected to become even more common in automobiles.

Consumer electronics such as smartphones, smart home devices, and wearable technology are a massive growth driver for the microcontroller industry, making more complex, power efficient devices. Consumer devices connected to the internet are growing rapidly and microcontroller sales continue to grow to meet demands for more smart and efficient consumer electronics products.
