IoT chips vary from traditional chips in that they utilize less power to do more targeted processing, whereas conventional chips are more frequently employed in general-purpose applications that need for computational processing. A reader once came to the following conclusion in an essay by Ed S. Perling to support this claim: IoT devices have to off-load communication, forget computing, to internet through an external device (‘IoT hub’) and continue to do what they had been doing. Adding an IP address to a ‘IoT hub’ looks more practical than connecting all devices to internet. Dusun IoT utilizes advanced IoT chip technologies from manufacturers like Rockchip, MTK, NXP, ESP32, Nordic, and Silicon Labs.
Why Need IoT Chips
IoT enables communication between billions of linked smart devices over the nearly ubiquitous communication protocols. Any system may utilize the Internet to innovate and make a variety of devices smarter and more conscious thanks to the widespread availability of dependable wireless IoT connectivity and affordable, low-power embedded components.
The rising demand for IoT devices is the main driver of the IoT chips industry’s expansion. The adoption of IoT chips used in various IoT devices is further fueled by the growing popularity of automation across a variety of end-user verticals, including healthcare, consumer electronics, industrial, automotive, BFSI, and retail. These devices necessitate the integration of connectivity expertise as well as the development of various networking protocols.
In addition, increasing inclination towards artificial intelligence (AI) will accelerate the IoT chips across the end-user verticals. The term “AIoT” stands for “AI+IoT,” It is the fusion of Internet of Things (IoT) with artificial intelligence (AI) technology. Underlying data is gathered via the IoT devices, and artificial intelligence analyses, analyzes, and executes associated operations. The two technologies complement each other.
Artificial intelligence (AI) enables devices to become programmable systems that can learn, reason, and process information like humans. As a result, IoT devices need AIoT chips with low power consumption, small size, and great performance for the operation of AI algorithms, data processing, and application-driven/triggered decision-making.
According to report from Mordor Intelligence, the global IoT market chip market size will reach USD 17.92 billion in 2023, and is estimated to reach USD 37.85 billion by 2028, growing at a CAGR of 16.13% during the forecast period (2023-2028).
Is the Single IoT Chip Enough for IoT Solutions?
IoT applications ideally require a single chip with reducing energy consumption combined with the miniaturization of form factor. These requirements have led to the development of various IoT SoCs (System on Chips). The IoT SoCs uses a more sophisticated technique to primarily improve the three key metrics that make up the chip’s “PPA” (power consumption,performance and area).
However, a single-chip solution is not always feasible or favored by all IoT solutions, because businesses sometimes require more than just a single chip product. The IoT modules installed in various things must connect them to other nearby IoT devices or the cloud and exchange data. Here is an illustration of a block diagram for the DSGW-210 IoT gateway hardware. You can see how many IoT chips it uses.
Types of IoT Chips Available In the Market
IoT chips are vital in enabling IoT devices, facilitating the interconnection and functionality of the Internet of Things ecosystem. In detail, IoT chips provide essential functionalities for IoT devices, including data sensing and acquisition from sensors, wireless connectivity for communication, data processing and control capabilities, energy efficiency features, security, and encryption measures.
There are many IoT chips available in the market for different applications. Based on hardware, IoT chips may be divided into processor chip, sensor chip, connectivity IC (integrated circuit), memory device chip, and logic device chip.
For AIoT, there are four essential IoT chips: SoC, MCU, communication chip, and sensor chip.
- The SoC serves as the hub for data processing and is essential for achieving intelligence;
- The MCU serves as the focal point for data gathering and command execution, supporting SoC in realizing intelligence;
- Connectivity chip is the heart of data transmission and the key to distant communication;
- Sensor chip is the center of data acquisition and the foundation for detecting outside signals.
