MIPI Alliance Specifications
MIPI Alliance offers a comprehensive portfolio of specifications to interface chipsets and peripherals in mobile-connected devices. The specifications can be applied to interconnect a full range of components—from the modem, antenna and application processor to the camera, display, sensors and other peripherals. Manufacturers use the specifications to optimize performance, simplify the design process, reduce development costs, create economies of scale for their designs, and shorten time-to-market for their products.
Companies from across the mobile industry have adopted MIPI Alliance specifications. Every smartphone uses at least one MIPI Alliance interface and the solutions are commonly used in tablets and laptops. Companies in many vertical markets are also adopting MIPI Alliance specifications for current and future designs. Connected cars developed by automotive firms and wearables offered by sports and healthcare companies illustrate the range of devices and business ecosystems that benefit from MIPI Alliance specifications.
MIPI Alliance specifications serve six types of interface needs in a device: physical layer, multimedia, chip-to-chip/interprocessor communications (IPC), device control and data management, system debugging, and software integration.
Each specification is optimized to address three fundamental performance characteristics:
- low power to preserve battery life,
- high-bandwidth to enable feature-rich, data-intensive applications, and
- low electromagnetic interference (EMI) to minimize interference between radios and device subsystems.
MIPI Alliance offers its specifications as individual interfaces, enabling companies to use those that suit their own particular needs. Vendors can apply the interfaces with their own high-level features to provide added value or differentiate their products.
The specifications are available to MIPI Alliance members only. For information about joining MIPI Alliance, see Join MIPI.

MIPI Alliance specifications are developed by technical working groups that focus on specific market needs for interface technologies. Participants in each working group are international experts in the field of interest. Participants typically represent semiconductor companies, software vendors, IP providers, peripheral manufacturers, test labs and end-product OEMs.
Technical working groups are formed by the MIPI Alliance Board of Directors based on the recommendations of internal investigation groups or birds-of-a-feather groups. Once a working group is formed, it establishes a development roadmap and timeline that allow for plenty of dialog and discussion as the specification is drafted. Companies that are contributor members and above can participate in working groups.
A separate set of strategic working groups is in place to help provide guidance to the board and the technical working groups on marketing, technology development, and test-related activities.
