Functional overview

3.36

Improved inter-integrated circuit (I3C)

The I3C interface handles communication between the MCU and others, like sensors and

host processor(s), all connected on an I3C bus.

The peripheral implements the required features of the MIPI I3C specification v1.1. It can

control I3C bus-specific sequencing, protocol, arbitration and timing, and can act as

controller (formerly known as master) or as target (formerly known as slave). When acting

as controller the peripheral improves the features of the I2C interface, preserving some

backward compatibility: it allows an I2C target to operate on an I3C bus in legacy I2C

fast-mode (Fm) or legacy I2C fast-mode plus (Fm+), provided that the latter does not

perform clock stretching.

The I3C peripheral can be used with DMA to off-load the CPU.
