产品描述
The MIPI I3C interface is an evolutionary standard that improves upon the features of I2C, while maintaining backward compatibility. 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.
主要特性与优势
- Compliant with MIPI I3C Specification V1.0
- Compliant with MIPI I3C HCI Specification V1.0
- Supports up to 12.5 MHz operation using Push-Pull
- Open-Drain and Push-pull type transactions (as required)
- Supports legacy I2C devices
- Dynamic Addressing while supporting Static Addressing for Legacy I2C devices
- Legacy I2C Messaging
- I2C-like Single Data Rate Messaging (SDR)
- Optional High Data Rate Messaging Modes (HDR)
- Support for Multi-master (transferring the ownership of the bus to a Secondary Master if Present)
- Reception of In-band Interrupt Support from the I3C Slave devices
- Reception of Hot-Join from newly added I3C Slave devices
- Synchronous Timing Support and Asynchronous Time Stamping.
- APB/AHB Target Interface for Configuring/Controlling the IP with Interrupt output
- Small 16-byte (Configurable) FIFO for transferring data between Master and the Slave devices
- Independent Clocks for AHB and the I3C Interface
