UCIe™ (Universal Chiplet Interconnect Express™) Consortium Releases its 1.1 Specification

BEAVERTON, Ore.-- August 08, 2023 -- Today, the UCIe Consortium announced the public release of UCIe™ (Universal Chiplet Interconnect Express™) 1.1 Specification to deliver valuable improvements in the chiplet ecosystem, extending reliability mechanisms to more protocols and supporting broader usage models. Additional enhancements are included for automotive usages – such as predictive failure analysis and health monitoring – and enabling lower-cost packaging implementations. The specification also details architectural specification attributes to define system setups and registers that will be used in test plans and compliance testing to ensure device interoperability. The UCIe 1.1 Specification is fully backward compatible with the UCIe 1.0 Specification.

“UCIe Consortium is living up to its mission and establishing a vibrant chiplet ecosystem as the industry musters around UCIe technology,” said Dr. Debendra Das Sharma, chairman, UCIe Consortium. “The UCIe 1.1 Specification was developed by leaders in the industry to advance the chiplet ecosystem and address significant demand for full stack streaming protocol enhancements. We’re proud of the progress this release represents toward realizing our vision and our underlying efforts to establish a chiplet ecosystem by developing a robust compliance program.”
