Alphawave Semi has successfully taped out of one of the industry’s first UCIe IP subsystem on TSMC’s N2 process, supporting 36G die-to-die data rates. The solution is fully integrated with TSMC’s Chip-on-Wafer-on-Substrate (CoWoS) advanced packaging technology, unlocking breakthrough bandwidth density and scalability for next-generation chiplet architectures.

This milestone builds on the recent release of the Alphawave Semi AI Platform, proving readiness to support the future of disaggregated SoCs and scale-up infrastructure for hyperscale AI and HPC workloads. With this tape-out, Alphawave Semi becomes one of the industry’s first to enable UCIe connectivity on 2nm nanosheet technology, marking a major step forward for the open chiplet ecosystem.

“We’re proud to lead the industry into the N2 era with the first UCIe IP on this advanced node,” said Mohit Gupta, Senior VP & GM, Custom Silicon & IP, Alphawave Semi. “Our 36G subsystem validates a new class of high-density, power-efficient chiplet connectivity and paves the way for 64G UCIe and beyond—critical for AI and high-radix networking applications.”

Alphawave Semi’s one of the industry’s first UCIe IP subsystem on TSMC’s 2nm process delivers 36G performance with 11.8 Tbps/mm bandwidth density, ultra-low power and latency, and advanced features like live per-lane health monitoring and comprehensive testability. Compliant with UCIe 2.0 standard and supporting multi protocols, including PCIe, CXL, AXI, CHI and more with Alphawave Semi’s highly configurable and efficient Streaming Protocol D2D Controller.

Alphawave Semi is advancing key ecosystem collaborations to enable groundbreaking technologies, leveraging D2D-based open chiplet interoperability to drive a broader AI connectivity platform for the industry. Alphawave Semi’s UCIe IP on the TSMC N2 process affirms its position as one of the leading enablers of scalable, open chiplet ecosystems.

Alphawave Semi is already executing on its plans to deliver next-generation UCIe solutions, with 64G UCIe support — empowering AI and HPC customers to lead in a rapidly evolving chiplet-driven landscape.
