MCS Logic Inc. — 5 prefixes (MA-L)

A MAC address starting with one of MCS Logic's five registered prefixes (68:52:10, 00:1F:47, 54:15:89, 08:EF:3B, or C4:30:18) belongs to MCS Logic Inc., a South Korea-based fabless semiconductor company. Third-party company profiles describe it as designing SoCs for audio and communication devices — digital audio, Bluetooth modules, and MCU-based network controllers — putting these prefixes on hardware like soundbars, wireless speakers, and Bluetooth-enabled devices rather than a single-purpose gadget.

IEEE's MA-L registry lists five separate MCS Logic assignments: four filed as "MCS Logic Inc." and one (68:52:10) as "MCS Logic" without the corporate suffix. Three of the five blocks (00:1F:47, 08:EF:3B, C4:30:18) share an identical registered address in Yangjae-Dong, Secho-Ku, Seoul, while 68:52:10 and 54:15:89 point to a later Songpa-gu, Seoul address — consistent with one company relocating over time rather than five unrelated registrants.

Independent third-party B2B directories (Tracxn, EC21, Komachine, Kompass) corroborate an active company beyond the bare IEEE filing, describing MCS Logic as founded in 1997 and producing audio SoCs for soundbar, smart-audio, and car-audio applications. Direct verification against the company's own site was not possible — mcslogic.com refused the connection and its EC21 storefront returned a 403 — so this identity rests on secondary sources rather than a primary fetch.

No device-level teardown evidence ties any of the five prefixes to a specific named product, and no security advisories or CVEs reference MCS Logic. Both are sourced Unknowns, not a clean bill of health. A third-party lookup tool lists a 2023-07-28 "registered" date for 68:52:10, but IEEE's own MA-L data publishes no date column — that figure is a database artifact, not an IEEE fact, and is not carried into this record.
