The COVID-19 pandemic witnessed an increment in the use of Work-from-Home electronics equipment, which shifted the focus of semiconductor manufacturing units to produce more equipment for the same. This turned the focus from other vital industries relying on microcontrollers and semiconductor chips, like automotive and industrial automation. The industry is rapidly distributing the supply chain allocation for reviving the affected industries. The process should follow through 2022 and mid-2023, witnessing promising prospects for microcontrollers globally.


Key Market Trends

Automotive Applications to Drive the MCU Industry


The introduction of new-age technology in the automotive industry has encouraged the involvement of semiconductors and microcontrollers. According to IEEE Explore, an average of more than 50 Microcontroller Units (MCUs) are used in an automobile. The inclusions of connected tech, AI, autonomous driving, and other IoT services have created enormous demand for the deployment of MCUs.
The MCUs can be configured as per any requirement based on the architecture's versatility and offered functionality. The input/output (I/O) ports, microprocessor, connectivity options, technological platform, range of operation, power consumption, and other differentiating factors add to the customizability and flexibility of use for the MCUs in automobiles. Each MCU serves a dedicated purpose.
In the wake of surging fuel prices and climate change, carmakers are focusing on optimizing fuel consumption by monitoring the fuel efficiency of vehicles in real-time with the help of Electronic Control Units (ECUs), which are forms of microcontrollers. An ECU is the central controlling unit in modern vehicles responsible for monitoring various vehicular functions like fueling, infotainment, remote functionality, autonomous driving functions, parking aids, and electronic driving aids (like lane-keep assist, park-assist features, etc.), and others. Hence, ECUs demand highly reliable and robust hardware that can run compatible platforms and software for achieving the required crucial functions.
Autonomous vehicles and sensor-driven safety features like automatic brake assist, collision avoidance systems, etc., are the driving factors in the future of automobiles, incorporating MCUs. The MCUs housing sensors related to each function offer local computing followed by temporary data storage and transfer to the master controlling units or remote servers.
MCUs with sensors in automobiles also demand more robust and reliable quality promising accurate results and operation in various environmental constraints. For instance, in April 2022, Honda opted R-Car and RH850 by Renesas Electronics for use in the Honda SENSING 360 omnidirectional safety and driver assistance system. The 40 nm-process MCU provides good embedded security at a very low power consumption and high scalability for advanced automotive applications.
