格子I3C IP内核旨在符合MIPI I3C规范。此IP内核的主设备和从属版本都可用。
MIPI I3C接口通过为传感器提供快速，低成本，低功耗，双线数字接口，简化了移动无线产品中的传感器系统设计架构。I3C单个可扩展的，具有成本效益，功率高效的协议来解决与高的协议开销，功耗，非标准协议，用于中断单独的行，其余的要求的问题。实现I3C规范大大提高了以不断扩展的传感器子系统的实现灵活性，尽可能低廉。
I3C向后兼容许多Legacy I2C设备, but I3C offers greater than 10x speed improvements, more efficient bus power management, new communication Modes, and new Device roles, including an ability to change Device Roles over time (i.e., the initial Master can cooperatively pass the Mastership to another I3C Device on the Bus, if the requesting I3C Device supports Secondary Master feature).
