MIPI I3C Master v1.1 Controller IP offers impressive data transmission capacity for sensor integration.

Overview

I3C interface is a fast, low cost, low power, two wire digital interface for sensors in mobile wireless products, compliant with MIPI Alliance. Our I3C supports several communication formats all sharing a two wire interface - SDA and SCL. SDA is a bidirectional data pin while SCL can be either a clock pin or a data pin while in HDR mode. The type of communication supported by I3C. I2C-like communication with SCL clock speed up to 12.5 MHz , MIPI-defined transmissions that allow the master to communicate to one or all slaves on the bus.

HDR mode using ternary number symbols to achieve two data transmissions per equivalent clock cycle. A subset of I2C communication to legacy I2C slaves, if present on the bus. Slave initiated request to master, e.g. In-band interrupt, address request.
