Leaders in semiconductors, packaging, IP suppliers, foundries, and cloud service providers join forces to standardize chiplet ecosystem

Key highlights:

  • Advanced Semiconductor Engineering, Inc. (ASE), AMD, Arm, Google Cloud, Intel Corporation, Meta, Microsoft Corporation, Qualcomm Incorporated, Samsung, and Taiwan Semiconductor Manufacturing Company launch new Universal Chiplet Interconnect Express (UCIe) technology to establish a chiplet ecosystem and future generations of chiplet technologies.
  • UCIe 1.0 specification ratified to provide a complete standardized die-to-die interconnect with physical layer, protocol stack, software model, and compliance testing to enable end users to easily mix and match chiplet components from a multi-vendor ecosystem for System-on-Chip (SoC) construction, including customized SoC.
  • New open standard establishes an open chiplet ecosystem and ubiquitous interconnect at the package level. Interested companies and institutions are encouraged to join.

Beaverton, OR, USA – March 2, 2022 – 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.
