Advanced Semiconductor Engineering, Inc. (ASE), AMD, Arm, Google Cloud, Intel Corporation, Meta, Microsoft Corporation, Qualcomm Incorporated, Samsung, and Taiwan Semiconductor Manufacturing Company today announced the formation of an industry consortium that will establish a die-to-die interconnect standard and foster an open chiplet ecosystem.
The organization, representing a diverse ecosystem of market segments, will address customer requests for more customizable package-level integration, connecting best-in-class die-to-die interconnect and protocols from an interoperable, multi-vendor ecosystem.
Universal Chiplet Interconnect Express (UCIe) Specification now available
The founding companies also ratified the UCIe specification, an open industry standard developed to establish a ubiquitous interconnect at the package level. The UCIe 1.0 specification covers the die-to-die I/O physical layer, die-to-die protocols, and software stack which leverage the well-established PCI Express® (PCIe®) and Compute Express Link™ (CXL™) industry standards. The specification will be available to UCIe members and available to download on the website.
Open for membership
The founding companies represent a wide range of industry expertise and include leading cloud service providers, foundries, system OEMs, silicon IP providers, and chip designers, and they are in the process of finalizing incorporation as an open standards body. Upon incorporation of the new UCIe industry organization later this year, member companies will begin work on the next generation of UCIe technology, including defining the chiplet form factor, management, enhanced security, and other essential protocols.
