Over the past year, MIPI has adopted a record number of new and updated interface specifications for mobile, the Internet of Things (IoT), automotive and related industries. Three key 2021 releases in particular have garnered significant media interest and coverage:
Recent industry articles covering the new features in these specifications offer valuable insights into their impact for designers and developers across a wide range of applications and use cases. Here we present a sampling of the recent coverage for reference in learning more about the new specifications.
In September 2021, MIPI announced updates to the I3C Basic utility and control bus specification, boosting speed and flexibility for a broad array of products. MIPI I3C and the publicly available I3C Basic are designed as the successors to the I2C interface and can be used to create innovative designs for smartphones, wearables and systems in automobiles and server environments.
“I3C Basic has already been adopted by JEDEC in its Sideband Bus and DDR5 standards. The MIPI Alliance also is actively working with DMTF (Distributed Management Task Force), ETSI (European Telecommunications Standards Institute) and TCA (Trusted Connectivity Alliance)," Tim explains in the article. "We hope to foster collaboration between many different organizations to continue to align I3C with the needs of the broader industry, and these collaborations with incredible organizations are helping us achieve that goal. Plus, whenever I3C Basic is adopted by another organization, it results in a richer ecosystem and fosters more interoperability within the broader industry.”

“Established interfaces such as I2C, SPI and UART have served the embedded electronics industry well since their introduction in the late 1970s and early ’80s,” he writes in the article. “But since that time, several industry advancements, prevalent not only in IIoT but also across the wider electronics industry, have placed increasing pressure on these legacy interfaces ... To solve these challenges, developers will need to implement new command and control interfaces that provide higher bandwidths, use the minimum number of wires and pins, consume the minimum amount of power and enable the whole system to minimize its power consumption.”

In late 2021, MIPI adopted A-PHY v1.1, the newest version of the asymmetric long-reach (up to 15 m) SerDes physical-layer interface for automotive applications such as advanced driver assistance systems (ADAS), autonomous driving systems (ADS) and other surround-sensor applications, including cameras and in-vehicle infotainment (IVI) displays.
“The doubling of bandwidth was accomplished by adding support for Star Quad (STQ) cables that provide dual differential pairs of conductors within a single shielded jacket,” Dan explains in the article. “This enables two A-PHY ports over a single cable, saving cost, weight and complexity compared with using two separate coaxial or shielded twisted pair cables.”

Also in late 2021, MIPI adopted CSI-2 v4.0, a major update to the world’s most widely implemented embedded camera and imaging interface. The new version of the specification is designed to enable the next generation of always-on, low-power, machine-vision applications.
