MIPI I3C
A modern, high-speed, low-power bus that upgrades I²C with higher throughput, dynamic addressing, in-band interrupts, and predictable timing for dense sensor networks.
Overview
MIPI I3C is a next-generation interface that connects sensors, MCUs, and peripherals with higher speed and lower power than I²C. It adds Dynamic Address Assignment (DAA), In-Band Interrupts (IBI), and scalable bandwidth, enabling efficient and flexible system designs.
Why This Technology Matters
I3C unifies heterogeneous sensors on a single, high-bandwidth bus while cutting power use and wiring complexity. With up to 12× I²C throughput, push-pull signaling, deterministic timing, and backward compatibility, it enables smoother migration and long-term scalability in modern embedded systems.
Why You Need It
If you're building products with multiple sensors, migrating from I²C, or need deterministic real-time performance, I3C delivers the bandwidth and power efficiency required for modern designs. Backward compatibility means you can adopt it incrementally without redesigning your entire system.
