What Yu Taiwei does

Yu Taiwei (裕太微电子股份有限公司, ticker 688515) is a fabless semiconductor company founded in 2017 and headquartered in Suzhou, Jiangsu, China. It specializes in the R&D, design, and sale of high-speed wired communication chips, with five product lines all in mass production: network Ethernet PHY chips (10M/100M/1G/2.5G), network Ethernet switch chips, PCIe Ethernet NIC chips, automotive Ethernet PHY chips (100M and 1G), and automotive Ethernet switch chips including TSN products. The company holds SGS ISO 26262:2018 ASIL D functional safety certification, AEC-Q100 Grade 1, OPEN Alliance C&S interoperability certification, and ISO 9001, and is recognized as a national Specialized and Novel "Little Giant" enterprise and High-Tech enterprise.

The company's technology is built on independent intellectual property spanning high-speed DSP, analog front-end design, SerDes, TSN protocols, and functional safety architecture. Flagship products include the YT99 series automotive TSN Switch chip (the first China-developed mass-produced chip combining self-developed PHY, TSN switching, and independent controllability, deployed in the GAC Aion Hyper GT with 100% localization), the YT80 series automotive Ethernet PHY (cumulative shipments exceeding 15 million units), the second-generation YT8821-VD 2.5G PHY, the YT6801 PCIe NIC chip (first mainland-China PCIe gigabit Ethernet controller), and the upcoming YT78/79 automotive SerDes chipset based on the HSMT public standard. The company has 46 granted invention patents plus 100 additional filed applications and participates in IEEE 802.3 standard-setting.

Yu Taiwei operates a direct-sales enterprise go-to-market model with offices in Suzhou (HQ and R&D), Shanghai (R&D, recognized as a Pudong New Area enterprise R&D institution), Chengdu, Shenzhen, Nanjing, and Singapore, serving automotive OEMs and Tier 1 suppliers, Wi-Fi 6/7 router and 10G PON equipment vendors, telecom operators, and industrial control customers. It completed its IPO on the Shanghai Stock Exchange STAR Market on February 10, 2023. Revenue scaled from approximately RMB 40 million in 2021 to RMB 88 million in 2025, though the company has remained unprofitable as R&D investment (70% of revenue in H1 2025) outpaces commercialization.
