Qualitas Semiconductor Successfully Develops UCIe v2.0-Compliant PHY IP, Enabling Up to 512Gbps Die-to-Die Connectivity

SEOUL, South Korea – June 10, 2025 – QUALITAS SEMICONDUCTOR CO., LTD. (hereinafter referred to as "Qualitas") (KOSDAQ: 432720), a leading provider of high-speed interconnect solutions, has announced the successful development of its new UCIe (Universal Chiplet Interconnect Express) PHY IP, fully compliant with the latest UCIe specification version 2.0.

The newly developed UCIe PHY IP supports up to 32 transmit and receive channels, delivering an impressive data transfer rate of up to 512Gbps (56GB/s). This IP is designed to meet the demanding requirements of high-bandwidth, low-latency Chiplet communication, making it an ideal solution for next-generation heterogeneous integration. Notably, the total trace width required for all 32 channels is approximately 1mm, enabling significantly higher transmission density compared to conventional interfaces such as PCI Express.

Going beyond IP design, Qualitas independently developed both the package and test board, conducting full silicon-level validation in-house. Through advanced high-speed measurement techniques and test-driven modeling, the company has established a robust end-to-end verification framework, which is essential for performance prediction and quality assurance in complex chip environments.

UCIe enables dense and efficient data interconnection between heterogeneous Chiplets. Unlike traditional interfaces, it requires optimized adaptation to package and board conditions. With deep expertise in customization and signal integrity analysis, Qualitas provides tailored solutions that support the successful implementation of customer systems.

Dr. Duho Kim, CEO of Qualitas Semiconductor, said, “Our new UCIe PHY IP showcases a successful implementation of next-generation Chiplet interconnect with proven silicon validation. As global interest in UCIe accelerates, we remain committed to expanding our high-speed interface solutions and delivering fully tailored support to meet the evolving needs of our customers.”
