The microcontroller (MCU) field is rapidly evolving as the demand for smarter, more efficient and versatile electronic devices continues to grow. The compact and powerful brains behind a range of devices, from home appliances to industrial equipment, microcontrollers are at the forefront of technological advancement and are undergoing tremendous change. So this article will also look at the top 10 microcontroller trends for 2024.


1. Enhanced Integration Capabilities

A prominent trend for microcontrollers in 2024 is enhanced integration capabilities. Manufacturers are increasingly embedding additional functionality, such as wireless communications and advanced security features, directly into the microcontroller unit. This integration simplifies design complexity and reduces the overall size and power consumption of the device.

Enhanced integration is particularly important for the development of IoT devices, where space and power efficiency are critical. These advances are giving rise to a new generation of compact, connected and secure devices, paving the way for more complex applications in the consumer and industrial sectors.

Texas Instruments' SimpleLink MCUs are a good example. These MCUs offer integrated wireless connectivity and advanced security, demonstrating the trend toward more integrated microcontroller solutions.


2. Improving Energy Efficiency

Energy efficiency continues to be a key focus of microcontroller development, and in 2024 we will see a new wave of ultra-low power MCUs designed to extend battery life in portable and wearable devices. These MCUs are carefully designed to operate at the lowest power levels while maintaining optimal performance, a fundamental requirement for applications such as remote sensors and health monitoring devices.

ST's STM32L family of MCUs stand out for their ultra-low power consumption, making them ideal for energy-efficient applications in portable and wearable devices.


3. Advanced security features

As the world becomes increasingly connected, microcontroller security becomes more and more important, and in 2024 we will see MCUs with advanced security features become the standard. These include hardware-based encryption, secure boot processes, and integrated threat detection.

This trend is critical to address the growing concerns about data privacy and cybersecurity threats, especially in applications involving sensitive data such as financial transactions or personal health information.

Microchip's SAM L10 and SAM L11 MCU families feature hardware-based encryption and secure boot functionality to meet the growing demand for secure microcontroller solutions.

 

4. Increased Processing Power

The processing power of microcontrollers is increasing significantly. The need to process complex algorithms and large datasets is driving the need for faster, more powerful MCUs, especially in applications such as artificial intelligence (AI) and machine learning (ML).

In 2024, we're likely to see microcontrollers equipped with higher clock speeds, more cores, and larger memory capacities. This trend enables more sophisticated edge processing capabilities, reduces the need for cloud-based computing, and facilitates faster real-time decision making in applications such as self-driving cars and smart manufacturing.

Featuring a high-performance Arm Cortex-M core and Zephyr RTOS functionality, NXP's i.MX RT Crossover MCUs are microcontrollers optimized for real-time Ethernet protocols in industrial IoT and automotive applications.


5. Miniaturization

The trend toward microcontroller miniaturization continues unabated, with manufacturers producing smaller and smaller MCUs without sacrificing functionality. This miniaturization is critical for space-constrained applications such as medical implants or wearable technology. Smaller MCUs enable more compact designs and contribute to the aesthetics of consumer products.

Microchip Technology PIC10F family exemplifies the trend toward miniaturization of microcontrollers. These MCUs are small, yet powerful, and designed for cost-sensitive and space-constrained applications.


6. Increased Connectivity Options

Connectivity is a key trend in the microcontroller industry, with more and more MCUs featuring a variety of connectivity options. This includes support for legacy protocols such as Ethernet as well as newer standards such as 5G, NB-IoT and LoRaWAN.

The ability to support multiple connectivity options is critical to the development of IoT devices. This trend enables devices to interact more efficiently in the IoT ecosystem, enhancing data exchange, remote monitoring and control capabilities, which are critical for applications ranging from smart homes to industrial automation.

Espressif's ESP32 family is known for its wide range of connectivity options, making it a versatile choice for connectivity applications.


7. Utilizing the RISC-V Architecture

The adoption of the RISC-V architecture in microcontrollers is gaining momentum. This Open Standard Instruction Set Architecture (ISA) provides flexibility and customization unmatched by proprietary ISAs.RISC-V allows manufacturers and designers to develop customized microcontroller solutions for specific applications without the licensing and royalty restrictions associated with traditional ISAs. This trend is fostering innovation and competition in the microcontroller market, resulting in more diverse and specialized MCU products.

SiFive offers a range of RISC-V based microcontrollers that are gaining popularity due to their flexible customization and open source architecture. SiFive's small cores are very energy efficient, allowing more cores to be installed on the chip for efficient and cost-effective computing.


8. Expansion in Automotive Applications

The automotive industry continues to be a key driver of microcontroller innovation. 2024 will see an expansion of MCU applications in vehicles, from engine control units to advanced driver assistance systems. The trend towards electric and self-driving cars is particularly influential and requires MCUs with high reliability and real-time processing capabilities.

Infineon's AURIX microcontroller family is designed for automotive applications. It offers high performance, safety features and real-time functionality for ADAS and EV control.


9. Focus on Sustainability

Sustainability has become an important consideration in the microcontroller industry. Manufacturers are addressing this challenge by developing MCUs using environmentally friendly processes and materials. In addition, they are emphasizing the need to build MCUs that enable energy-efficient features in the final product, thereby reducing our carbon footprint.

This trend is in response to growing environmental concerns and the quest for sustainable technology solutions. Manufacturers are addressing environmental challenges by prioritizing sustainability in MCU development and meeting the growing consumer demand for eco-friendly products.

The RL78 series of MCUs from Renesas Electronics features low power consumption and efficient operation, in line with the industry's sustainability trend.


10. Development of Specialized MCUs

The trend of developing application-specific microcontrollers (ASMCUs) will dominate in 2024. These specialized MCUs are designed to meet the unique requirements of specific applications, such as smart home devices, wearable technology or industrial automation.

Maxim Integrated's (now part of Analog Devices) Wearable Health MCUs, designed for health and fitness wearables, exemplify the trend toward developing specialized MCUs.


Trends in microcontroller technology highlight a landscape of innovation, efficiency and customization, while reflecting an industry that is adapting to the changing needs of the digital age and shaping the future of technology.
