The main purpose of MIPI I3C is threefold:
- To standardize sensor communication,
- To reduce the number of physical pins used in sensor system integration, and
- To support low power, high speed, and other critical features that are currently covered by I²C and SPI.
MIPI I3C’s purpose is now widening to cover many types of devices currently using I²C/SMbus, SPI, and UART.
