DCD-SEMI

Select

The DI3CM-HCI is a MIPI® I3C Host Controller designed to connect modern embedded systems with a new class of smart peripherals. It provides a robust, medium-speed control and utility interface for sensors, actuators, and companion controllers, seamlessly linking them with the application processor. As a next-generation alternative to legacy I²C and SPI buses, DI3CM-HCI delivers higher bandwidth, lower power consumption, and more efficient, feature-rich communication for advanced electronic designs.

The DI3CM-HCI is a high-performance MIPI® I3C Host Controller engineered to bring next-generation efficiency and intelligence to embedded systems. Designed as a modern replacement for legacy I²C and SPI interfaces, it enables significantly higher bandwidth, lower power consumption, and more reliable data transfer between devices.
