I2C Bus Market Outlook from 2024 to 2034

The global sales of I2C Bus are estimated to be worth USD 8,561.1 million in 2024 and anticipated to reach a value of USD 15,995.0 million by 2034. Sales are projected to rise at a CAGR of 6.5% over the forecast period between 2024 and 2034. The revenue generated by I2C Bus in 2023 was USD 8,042.3 million. The market is anticipated to exhibit a Y-o-Y growth of 4.6% in 2024.

Phillip Semiconductors developed I2C in 1980 to cut costs by simplifying the interface for connecting a central processing unit (CPU) to peripheral chips in a television. It began with a battery-powered interface but later switched to an internal bus system.

A multi-master serial bus (Inter-IC or I2C) connects low-speed peripherals to a motherboard, mobile phone, embedded system, or other electronic devices.

Although slower than most buses, I2C is a low-cost architecture that is ideal for low-speed peripherals such as digital-to-analog and analog-to-digital controllers, built-in tests, real-time clocks, color balance, tone, and volume control.

Key Industry Highlights

Increase in highly-connected ‘Internet of Things’ (IoT) Networks Driving Market Demand.  

The core components of the highly connected "Internet of Things" (IoT) networks, which are increasingly being employed in smart city and smart grid designs, are digital devices like sensors. Digital interfaces for the newest sensors, such as temperature, pressure, and humidity sensors, are streamlining the IoT interface to increase system reliability and functionality.

The basis for control and optimization is the ability to access data from devices located anywhere in the globe that are connected to "big data" information systems via the internet. This is at the core of global innovations in smart grid and smart cities. In certain situations, connecting sensors to the internet of things is rather straightforward, but in others, it requires more consideration.

I2C and SPI interfaces are two commonly used interfaces that serve as a bridge between digital devices and the internet of things. I2C bus is frequently used for communication between microcontrollers and sensor arrays, displays, internet of things (IoT) devices, EEPROMs, etc., due to its simplicity. Thus, an increase in the adoption of IoT devices has fueled the demand for the I2C bus market.

Evolution and Expansion of Consumer Electronics, Telecommunications, and Industrial Electronics Sectors to Boost Sales of I2C Bus.

As electronics, telecommunications, and consumer electronics fields grow, they shape the world around us. A digital revolution is sweeping the globe driving up demand for electronics and telecommunications. This leads to more people using electronic devices. The semiconductor market has been changing and growing worldwide. The huge demand for cutting-edge smart devices and related tech improvements has a big impact on this growth.

A dependable interface to transmit data plays a crucial role in industrial, telecommunications, and electronics fields to enable low-speed close-range communication. The inter-integrated circuit bus is a 2-wire, two-way bus. I2C proves to be a solid option for projects that need simple setup at a low price tag rather than high speeds.

It has an impact on sending and managing user-driven actions getting data from hardware sensors and interacting with multiple micro-controllers.

This means the quick expansion of areas such as telecommunications and electronics, has resulted in I2C buses gaining wide acceptance.

Scarcity of Skilled Professionals for Design and Repairs of I2C to Hinder Market Growth

The need for skilled workers is growing in the ICT field and other parts of the digital economy due to cutting-edge digital tech. A worldwide lack of qualified experts and workers might slow down economic growth.

The I2C bus field is moving toward modernization by adding smart tech. I2C links microcontrollers EEPROMs, I/O ports, and other devices in embedded systems. Often, a microcontroller acts as the master device, while various peripheral devices serve as slaves.

The creation, fixing, and use of I2C systems need know-how, which is hard to find in the industry right now. Not having enough skilled workers to manage and fix these circuits between chips is a big problem for operations.

I2C has some downsides. It makes circuits more complex with extra master/slave setups. This makes them harder to run and means you need designers who know their stuff. So, not having enough of these skilled designers is slowing down how fast the market can grow.

Limitations of I2C Bus Affecting Market Growth

The I2C Bus works well for projects that need to be set up and rather than ones that need high speed. You can choose from a few very limited communication speeds, and many devices can't send data at higher speeds. You have to provide some support for each speed on the bus to stop slower devices from getting incomplete messages, which could cause problems.

Also, because of how the communication lines are set up (open-drain), I2C uses more power than other ways of sending data. Several slave devices share an I2C bus; if any one of these slaves acts up (keeps SCL or SDA low for too long), the bus will stop working. No more messages will be sent back and forth.

The market has also been held back by its role, which boosts protocol overhead and cuts throughput. This means these shortcomings of the I2C bus have an impact on the I2C bus market.
