The OUI 94:1F:A2 is an IEEE MA-L block registered to Wuhan YuXin Semiconductor Co., Ltd., based in the Donghu New Technology Development Zone in Wuhan, Hubei, China. YuXin is a fabless storage-semiconductor company — its public product portfolio centers on embedded and removable storage (SLC and SPI NAND, eMMC, eMCP, MicroSD, M.2 and enterprise SSDs) along with DDR3/DDR4/LPDDR4X DRAM modules and multi-chip packages, aimed at mobile, consumer, PC, server, automotive, and AIoT markets. It is not a networking-silicon vendor, so no router, switch, or Wi-Fi product line is associated with this block; a storage vendor holding a globally-administered OUI is most consistent with embedded or server-class devices that expose a management-plane or interface MAC. A globally-administered 94:1F:A2 address therefore identifies genuine YuXin-registered hardware, but as with any OUI, locally-administered/randomized MACs and re-badged silicon mean the prefix alone is not a complete asset identifier. Note also that IEEE publishes no assignment date for OUI blocks: any "date registered" surfaced by third-party MAC-lookup tools (e.g. the 2022-09-08 value on maclookup.app) is a database artifact, not an IEEE fact, and is recorded here as Unknown. Take care to distinguish this entry from the separately registered TCL Yuxin Zhixing Technology (80:0E:A9) and Yuxing Electronics HK (00:07:67).
- IEEE assignment
- 94:1F:A2 → Wuhan YuXin Semiconductor Co., Ltd. [Confirmed] — enrichment/registries/oui.csv (line 400, raw Assignment "941FA2"); cross-checked maclookup.app
- Registry / block size
- MA-L (24-bit OUI; ~16.8M addresses) [Confirmed] — enrichment/registries/oui.csv; not present in mam.csv (MA-M) or oui36.csv (MA-S)
- HQ / country
- 15F Haida Innovation Plaza, No. 66 of Chuangye Road, Donghu New Technology Development Zone, Wuhan, Hubei, CN 430074 [Confirmed] — enrichment/registries/oui.csv
- Registration date
- Unknown — IEEE publishes NO assignment/registration date (oui.csv columns are only Registry, Assignment, Organization Name, Organization Address); the "08 September 2022" on maclookup.app is a third-party database artifact, not an IEEE fact [Confirmed that no IEEE date exists] — https://maclookup.app/vendors/wuhan-yuxin-semiconductor-co-ltd

- Name variants / disambiguation
- IEEE canonical "Wuhan YuXin Semiconductor Co., Ltd."; also "Yuxin Semiconductor" / "宇芯半导体" in Chinese directories. Distinct from TCL Yuxin Zhixing Technology (80:0E:A9) and Yuxing Electronics HK (00:07:67) — separate oui.csv rows [Confirmed] — enrichment/registries/oui.csv
- Security context
- no public CVEs, disclosed vulnerabilities, or supply-chain incidents specific to this vendor found as of June 2026; produces storage (not network-infrastructure) silicon; standard supply-chain caution for any Chinese semiconductor vendor in defense/critical-infrastructure contexts, but no advisory names this company [Likely] — https://www.cisa.gov/news-events/cybersecurity-advisories/aa22-279a
- Analyst note
- 94:1F:A2 on a globally-administered address identifies genuine YuXin hardware, most plausibly an embedded storage device given the portfolio; OUI alone is not a complete asset identifier. No datasheet tying the prefix to a specific SKU was found.
