IoT Microcontroller Market Size & Trends

The global IoT microcontroller market size was valued at USD 4,960.1 million in 2022 and is expected to expand at a compound annual growth rate (CAGR) of 13.9% from 2023 to 2030. The increasing number of IoT connections among consumer and enterprise sectors and the need for low-power, high-performance, and energy-efficient connected products are some of the primary factors driving market growth. Also, a growing preference for embedded Non-Volatile Memory (eNVM) solutions over Product-in-Package (SiP) in high-end applications such as industrial automation, smart utilities, and smart transportation is expected to bode well for the market growth over the next few years. However, the need for industry standards, optimization, and data security of IoT-connected devices is expected to hamper the market growth over the forecast period.

U.S. IoT Microcontroller Market size and growth rate, 2023 - 2030

The global slowdown in the automotive industry witnessed in 2018 and 2019 had a negligible impact on overall microcontroller unit (MCU) sales. Although the overall MCU market witnessed an upward trend in 2018, the average selling price of MCUs continued until H2/2020. On the other hand, the outbreak of the COVID-19 pandemic took a severe toll on the semiconductor manufacturing industry. Economies worldwide implemented stringent measures to arrest the spread of novel coronavirus.

The measures include strict lockdowns and sealing international borders to prevent trade from disrupting the supply chain. Furthermore, enterprises compelled employees to work remotely. Consequently, the market experienced a sudden increase in demand for IoT-enabled smart devices, wearables, home computers, and mobile phones. MCU manufacturers witnessed several challenges in balancing supply and demand. Several production facilities were suspended temporarily, and international borders were closed for trade.

As a result, the industrial sector is currently confronting a looming shortage of semiconductors and several components, including microcontrollers and microprocessors. Although the restrictions have been relaxed in several parts of the world and trade activities have resumed, the shortage of semiconductors is expected to continue until 2023. The average selling prices of MCUs are also likely to remain affected until Q4 2023. As such, the fluctuating selling prices of MCUs and the shortages of components, which are turning out to be one of the major bottlenecks for OEMs, device manufacturers, and automakers, are expected to restrain the market's growth.

The outbreak of the COVID-19 pandemic triggered a level of healthcare awareness among people. As such, the demand for wearables capable of monitoring and tracking various health parameters, such as oxygen level and heart rate, significantly grew. Concerns over maintaining health and hygiene, the increased popularity of fitness apps, and awareness about physical fitness and wearable devices, especially in countries such as Poland, China, the UK, Germany, and India, fueled the adoption of wearable technology.

Application Insights

Based on application, the market is categorized into industrial automation, smart homes, consumer electronics, and others. The industrial automation segment dominated the market with a revenue share of 33.1% in 2022. Industrial automation aims to streamline processes, increase operational efficiency, and improve productivity. IoT microcontrollers enable automation by connecting various devices and systems, allowing real-time data monitoring and control. It reduces downtime, optimized resource utilization, and improves operational performance.

Global IoT Microcontroller Market share and size, 2022

The smart home segment is estimated to register a significant CAGR of 15.6% over the forecast period. The smart home segment includes home appliances. Advancements in app-controlled (notably mobile app) smart devices create the need for safe, secure, and energy-efficient applications such as HVAC and energy management, lighting, and infotainment. This trend is expected to support the market growth for the smart home segment over the next few years.

The consumer electronics segment encompasses smartphones, wearables, and others. The COVID-19 outbreak compelled the employees to work remotely. It has further triggered the demand for smart wearables such as smartwatches and fitness trackers. Increasing fitness and health awareness among millennials is also likely to spur wearables sales, which is expected to continue over the next few years. Therefore, the adoption of low-power MCUs coupled with short-range wireless connectivity, notably 8-bit integrated with Bluetooth/KNX/Zigbee/Wi-Fi-based protocols, is expected to drive the IoT MCUs sales over the forecast period.

Product Insights

Based on product, the IoT microcontroller market has been categorized into 8 bit, 16 bit, and 32 bit. The 32 Bit segment held the highest market share of 47.0% in 2022. The 32 Bit is the most compatible MCU for IoT applications. It processes multiple peripherals efficiently, is extensively used in industrial applications such as factory and building automation and is available at affordable prices.

The 8 Bit segment is estimated to register a significant CAGR of 13.7% over the forecast period. The 8-bit segment is extensively used for low-power applications such as smart wearables and connected devices. The growing preference for fitness wearables, particularly among millennials, is expected to drive the adoption of wearables. Lifestyle disorders, such as obesity, prompt individuals to opt for various fitness-related activities, and monitoring their performance using wearables is further expected to bode well for market growth over the next few years.

Regional Insights

Asia Pacific accounted for the largest market share of 48.7% in 2022. The growth is primarily driven by China, India, and Japan, which account for more than 50% of the overall market share. It can be ascribed to increasing demand for smart wearables and favorable government spending to promote smart city initiatives. The recent Regional Comprehensive Economic Partnership (RCEP) trade agreement with China and ASEAN countries, coupled with the increase in disposable income among emerging economies such as Vietnam, Malaysia, and Indonesia, are expected to create affordable smart home devices among consumers, which will eventually drive the market growth over the forecast period.

IoT Microcontroller Market Trends, by Region, 2023 - 2030

On the other hand, Europe is projected to demonstrate growth at the highest CAGR of 13.8% over the forecast period. In Europe, more than 50% of the electricity meters have been replaced by smart meters as part of aggressive investments in grid modernization. Favorable government investments have particularly propelled the installation of smart meters across European countries, such as France, Spain, and the U.K., which supports market growth over the forecast period. All these factors are expected to open opportunities for market players to augment profitability and bode well for the market's growth for IoT microcontrollers over the forecast period.

Key Companies & Market Share Insights

Leading market players are investing aggressively in R&D initiatives to introduce innovative, low-power, and energy-efficient MCUs and foray into different application segments to retain existing customers while attracting new ones. MCU manufacturers, such as strategic partnerships and Mergers & Acquisitions (M&A), are also pursuing inorganic growth strategies to gain a competitive edge.

Besides M&A, OEM emphasizes research and development to develop energy-efficient MCUs for low-power applications. Companies also focus on developing products that comply with regional regulatory norms to eliminate the risk of losing business because of regulatory violations. For instance, in May 2020, NXP Semiconductor collaborated with OKdo, one of the business units of Electrocomponents Group, to develop E1, a single-board computer (SBC). The SBC includes NXP's LPC55S69 Microcontroller, offers a high-performance, secure, low-cost platform for IoT applications, and helps the company enhance its customer base.
