LONDON, UK and TORONTO, Canada, June 13, 2025 – Alphawave Semi has completed the tape-out of UCIe IP subsystem using TSMC’s N2 process, enabling 36G die-to-die data rates. This subsystem is integrated with TSMC’s Chip-on-Wafer-on-Substrate (CoareWoS) packaging technology, aiming to improve bandwidth density and scalability for future chiplet architectures.
This milestone follows the recent release of the Alphawave Semi AI Platform, demonstrating capability to support disaggregated SoCs and infrastructure for hyperscale AI and HPC workloads. With this tape-out, Alphawave Semi is among the first to implement UCIe connectivity on 2nm nanosheet technology, a step forward in the open chiplet ecosystem.
“We’re proud to lead the industry into the N2 era with one of the first UCIe IP on this advanced node,” said Mohit Gupta, senior VP and 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 UCIe IP subsystem on TSMC’s 2nm process supports 36G data rates with 11.8 Tbps/mm bandwidth density, low power consumption and latency, along with features like per-lane health monitoring and testability. It complies with the UCIe 2.0 standard and supports multiple protocols, including PCIe, CXL, AXI, CHI, through Alphawave Semi’s Streaming Protocol D2D Controller.
Alphawave Semi is working on ecosystem collaborations to support technologies using D2D-based open chiplet interoperability for AI connectivity in the semiconductor industry. Its UCIe IP on the TSMC N2 process supports scalable, open chiplet ecosystems.
“Our latest collaboration with Alphawave Semi underscores our shared commitment to driving advancements in high-performance computing through design solutions that fully leverage the performance and energy-efficiency advantages of TSMC’s advanced process and packaging technologies,” said Lipen Yuan, senior director of advanced technology business development at TSMC. “This milestone illustrates how close collaboration with our Open Innovation Platform (OIP) partners like Alphawave Semi can enable the quick delivery of advanced interface IP and custom silicon solutions to meet the increasing demands of AI and cloud infrastructure.”
Alphawave Semi is executing on its plans to deliver next-gen UCIe solutions, with 64G UCIe support, empowering AI and HPC customers to lead in a evolving chiplet-driven landscape.
