Covid-19 Impact on the Global IoT Microcontroller Industry

Microcontroller demand is expected to rise as the number of automotive applications (autonomous vehicles, electric vehicles, and so on), consumer electronics, medical devices, and other industrial uses increases. However, as more uncertainty abounds in the automotive and industrial sectors, microcontroller industry participants are having difficulty evaluating the demand, slowing GDP development in both developed and developing economies. On the other hand, IoT holds enormous promise for a wide range of industries, including manufacturing, healthcare, agriculture, transportation, and telecommunications. In the wake of the COVID-19 epidemic, the majority of governments throughout the world have allowed employees to work from home. According to data suggested by the International Trade Union Congress, 65 percent of countries favor working from home. To manage workers who work from home, companies are increasingly relying on remote-based workforce monitoring, this is driving up demand for IoT solutions. Thus, the impact of COVID-19 on IoT microcontroller was moderate in 2020.

Market Dynamics

Growing improvements in IoT technology is the primary factors driving the global IoT microcontroller market. IoT technology has reached its pinnacle, transforming a variety of industries by storing and processing data in a distributed manner while also improving output. The latest research data shows that there were more than 35 billion smart devices in 2021 and this number will climb up to 75 billion by 2025. Artificial intelligence, 5G, blockchain, and edge computing are major drivers of emerging IoT trends. The business value of IoT applications such as smart homes and buildings, smart wearables, autonomous automobiles, smart cities, smart factories, wireless sensors, location trackers, and much more may be found inside this interconnected web of technological breakthroughs.

In addition, the rising number of connected devices such as wearables and other consumer electronics is also one of the key aspects driving up the market demand. The market demand is being bolstered by the expanding popularity of connected devices and the rising need for smart devices in the healthcare sector. The growing demand for low-cost smart wireless sensor networks, as well as the expansion of internet connectivity in technologically emerging countries, is expected to drive the market in the coming years.

However, the IoT privacy and security concerns may hamper the market from growing. Because of the Internet of Things, a virus or ransomware infection can easily disable vital functions and services. For instance, in March 2018, a ransomware crippled Atlanta city's water services and ticket payment systems.

Market Segmentation

The global IoT microcontroller industry is segmented based on product, application, and geography.

Market By Product

• 32-Bit
• 16-Bit
• 8-Bit

In 2021, the 32-bit segment held a significant amount of share in the product type segment. 32-bit microcontrollers are capable of handling arithmetic operations of 32-bit values and thus they are faster compared to other microcontrollers. They take fewer instruction cycles to execute a function due to its wider data bus. Thus companies have been relentlessly launching 32-bit microcontrollers owing to the rising IoT requirements across the world. For instance, Renesas Electronics Corporation launched four latest RX651 32-bit microcontrollers catered in ultra-small 64-pin LQFP and BGA packages. These RX651 32-bit microcontrollers are ideal for compact IoT applications, without compromising performance.

Market By Application

• Smart Homes
• Industrial Automation
• Consumer Electronics
  • Wearables
  • Smartphones
  • Others
• Others (Smart Transportation and Logistics, Smart Retail, Smart Utility, and Other Applications)

Among applications, the segment of the smart home is likely to attain a considerable growth rate in the projected years. The hi-tech world is expanding and can provide many opportunities for businesses, and IoT for smart homes is no exception. The integration of IoT in smart homes has enabled easy control and monitoring, has enhanced security, efficiently saved cost and energy, and increased comfort in living. The Internet of Things vastly improves the ability to control and monitor all of the home's processes. Aside from lowering bills, energy savings help to reduce the negative impact on the environment and live a "greener" lifestyle. Thus, the smart homes application uses the most of IoT technology creating a high demand for the IoT microcontroller industry.
