The I3C bus is used for various sensors in the mobile/automotive system where the Host transfers data and control between itself and various sensor devices. The I3C interface is intended to improve upon the features of the I2C interface, preserving backward compatibility. This I3C defines a standard multi-Drop interface between Host processors and peripheral Devices (e.g., sensors). Implementing the I3C Specification greatly increases the flexibility system designers have to supplant incumbent interfaces (i.e., I2C, SPI, UART) and support a wide array of Devices of increasing complexity and diversity in their system (e.g., sensor subsystem) and at as low a cost as possible.
Arasan has participated in multiple MIPI I3C Interop Workshops to ensure compliance of its I3C Host IP, I3C Device IP, I3C Software and HDK.
