ADMtek Incorporated — 00:E0:92 (MA-L)
Summary
- // what this is
- ADMtek is registered to MAC prefix
00:E0:92in the IEEE OUI database. When a device's MAC address begins with00:E0:92, that block was registered by ADMtek — the OUI identifies the maker of the network hardware, which is not always the brand on the device. ADMtek has ceased operations, but the registration remains on record with IEEE. - // analyst note
- Substance here comes from company/product/acquisition history (founding, Intel alliance, priced Infineon acquisition), not from OUI count. Recommend a full IEEE oui.txt grep for "ADMTEK" if a definitive count of all assigned blocks is needed — only the project's local mirror was checked, showing one (00-E0-92).
About this vendor.
ADMtek Incorporated, registered to the single MA-L block 00:E0:92 at 1962 Zanker Road, San Jose, CA, is a defunct fabless semiconductor designer founded in 1997 and headquartered in the Hsinchu Science-Based Industrial Park, Taiwan, with the San Jose address serving as its US/international office. Its product line centered on networking and communications ASICs: Fast Ethernet PHY/MAC/NIC chips, HomePNA silicon, LAN modem chips, low- and high-density Ethernet switch ICs, and later MIPS-based SoCs licensing ARM cores for broadband home-gateway (ADSL/routing) applications. Intel took an equity stake and formed a product-development alliance with ADMtek specifically to co-develop low-cost single-chip Fast Ethernet switching ICs, underscoring the company's standing in the networking-silicon space rather than being a bare registration of convenience. ADMtek's independent existence ended in 2004: Infineon Technologies announced its acquisition on January 28, 2004 for roughly €80 million (~US$100 million) — Infineon's first acquisition in Asia — structured as a statutory merger under Taiwan law, absorbing ADMtek into Infineon's wireline communications business. Only one OUI block was located for this vendor across the project's local registries; despite that, the founding date, headquarters, Intel alliance, and priced acquisition together establish clear company substance beyond the IEEE record alone.

- Verified sample prefix
- 00:E0:92 (only prefix found for this vendor across the project's local registries; no independent full IEEE oui.txt scan performed to confirm no other blocks exist) [Confirmed] — the IEEE MA-L registry
- Date registered
- Unknown — IEEE's public OUI registry publishes no assignment/registration date; none fabricated or inferred [Confirmed]
- Security context
- Unknown — no CVE/security-advisory database checked in this pass; not asserting a clean history, legacy hardware from the late-1990s/early-2000s era with no ongoing vendor support since the 2004 acquisition [Unknown]
- Related vendors
- Infineon Technologies (acquirer, 2004) — no separate OUI block identified for Infineon under this research pass
- Company-substance assessment
- single OUI in local data, but founding (1997), Hsinchu HQ + San Jose office, Intel alliance, and a trade-press-documented ~$100M Infineon acquisition together constitute verifiable substance beyond a bare IEEE registration[Likely] — https://www.digitimes.com/news/a20040128PR201.html, https://www.bloomberg.com/profile/company/ADMTEZ:TT
