I3C Slave

IQonIC Works I3C Slave Core provides a slave interface for the following protocols:
- I2C standard mode (100kbps)
- I2C fast mode (Fm, 400kbps) and fast-mode plus (Fm+, 1Mbps)
- I2C high-speed mode (3.4Mbps)
- I3C single data rate (SDR, up to 12.5Mbps)

特色

Protocol engine implements the following I3C CCC commands: ENEC, DISEC, ENTAS0, RSTDAA, SETDAA, SETMWL, SETMRL, GETMWL, GETMRL, GETPID, GETBCR, GETDCR, GETSTATUS, GETMXDS, XTIME
XTIME ST, DT, TPH, and TU subcommands for timing control of a synchronous system
Dynamic address assignment, plus I2C legacy addressing
In-band Interrupts with configurable payload size
I3C error checking and recovery
Slave interface signals for private messages and CCC command data

优势

IQonIC Works I3C Slave Core implements I3C protocol sequencing and command processing. It provides a simple interface for a device to transfer data over I3C. Legacy I2C protocols are supported transparently.

应用

The MIPI I3C interface is an evolutionary standard that improves upon the features of I²C, while maintaining backward compatibility and is intended for use as a single interface that can be used for any sensor.
This standard offers a flexible multi-drop interface between the host processor and peripheral sensors to support the growing usage of sensors in embedded systems. The main purpose of MIPI I3C is threefold:

to standardize sensor communication,
reduce the number of physical pins used in sensor system integration and
support low-power, high-speed and other critical features that are currently covered by I²C and SPI.
