Abstract

Serial communication technologies such as I2C (Inter-Integrated Circuit) and SPI (Serial Peripheral Interface) have long been integral to avionics systems for data transfer between components, such as sensors, controllers, and peripheral devices. As avionics systems evolve and demand higher performance, older technologies like I2C and SPI face bandwidth, power efficiency, and scalability limitations. MIPI has developed the new I3C (Improved Inter-Integrated Circuit) standard to address these challenges. I3C is built with I2C fundamentals in mind while bringing several advanced features that resolve some of the challenges faced by I2C. Thus, offering a more efficient and scalable solution for modern avionics. This paper investigates some of these existing serial communication protocols, discusses how they are used in aviation, discusses their drawbacks, and discusses how I3C can address some of them. It will also discuss the challenges of adopting this new I3C protocol in aviation.
