3.3.4 MIPI-I3C Mode
When enabled, MIPI-I3C mode enables the SC4415 to behave as an I3C Master device.
3.3.4.1 Summary
The I3C application mode is based on the MIPI-I3C protocol specification v1.0, designed, and maintained by the MIPI
Alliance. This document does not include I3C protocol specific information such as protocol message formats or timing
information. For further detail about the I3C specification, refer to mipi.org.

part(s) of this material may be disclosed, reproduced or used for any purpose other than as

There are two signals required for the I3C application mode, SCL and SDA. The SCL signal is the serial clock signal driven
by the master and the SDA is the bidirectional data line used to exchange data between master and slave.
The APIO pin functions for I3C mode are shown in Table 3.3.4.1-1. For more information about the APIO pins refer to
Section 2.5.1.
Table 3.3.4.1-1 – APIO Pin Mapping for I3C Mode
3.3.4.2 Details
The following features are available in this mode:
I3C SDR (Single Data Rate) communications
I3C HDR-DDR (Double Data Rate) communications
In-Band-Interrupts handling
Device Hot-Join support
Select support for Common Command Codes (CCC).
I2C Legacy communications as defined by the I3C specification
Internal programmable pull-up bus resistors
Configurable Clock rates for I2C and I3C devices, up to 12.5MHz
The available commands specific to I3C Mode are listed in Table 3.3.4.2-1. Details about the command and its usage
can be found by referring to the relevant section for the command in Section 5.4.
