What is I3C?

I3C (Improved Inter Integrated Circuit) is a two-wire, multi-drop serial interface for connecting peripherals to a processor. It is designed to improve upon and replace I2C while offering higher data rates, lower power consumption, and better support for mobile, IoT, and automotive applications. I3C incorporates features like in-band interrupts, dynamic address assignment, and standardized command codes to enhance system-level integration.

What other technologies are related to I3C?

I3C Competitor Technologies

I2C

I2C (Inter-Integrated Circuit) is a serial communication protocol that I3C is designed to replace, offering improved performance and features.

SMBus

SMBus (System Management Bus) is another serial communication protocol similar to I2C, and therefore also a competitor that I3C aims to replace.

SPI

SPI (Serial Peripheral Interface) is a synchronous serial communication interface that is used for high-speed, short-distance communication. While different in architecture, it serves a similar purpose in some applications.

PMBus

PMBus (Power Management Bus) is a power management protocol, and I3C competes with it in applications where power management is integrated with other sensor and control functions.

UART

UART (Universal Asynchronous Receiver/Transmitter) is an older serial communication protocol that is a competitor, though it doesn't offer the features of I3C. It is sometimes used in similar, low-bandwidth applications.

I3C Complementary Technologies

eSPI

eSPI (enhanced Serial Peripheral Interface) is a bus often used for low-bandwidth peripheral communication. I3C can complement eSPI in system designs by handling other sensor or control functions.
