I3C Slave Controller

The Arasan I3C Slave Controller IP Core Implements Slave functionality as defined by the MIPI Alliance’s I3C Specification. The I3C bus is used for various sensors in the mobile/automotive system where an I3C Master transfers data and control information between itself and various sensor devices. The I3C Slave Controller IP Core can be easily integrated into the Sensor/Slave devices with minimal gate count.

The I3C Slave controller is highly configurable (synthesis time) to provide an optimal solution based on the Device’s requirements. This include, acting as a legacy I2C device, Support for Dynamic Address Assignment, HDR (any of the three defined HDR Modes) and a configurable FIFO for data transfers. In addition, optional I3C slave functions like Interrupt generation, Hot-Join request generation and advanced slave with secondary master capabilities can be configured for more complex slaves. Also, the I3C Slave Controller IP provides direct signalling to connect to the IO Buffers (SCL and SDA). Please note that the User need to provide appropriate IO buffers to meet the I3C specification.

The I3C Slave controller implements support for legacy I2C Slave functionality, Open-drain and Push-pull operation of I3C Interface, and Dynamic Addressing support. The I3C Slave Controller supports the required SDR mode with Clock frequency of up to 12.5 MHz and optionally the any or all of the three HDR modes as defined by the I3C Specification. The included 16 byte FIFO (Configurable) is used to handle data transfers between IP and the Application.
