AMICCOM Electronics Corporation — 2 prefixes (MA-L)

A MAC address starting with C4:FE:E2 or 18:7A:93 belongs to AMICCOM Electronics Corporation, a Taiwanese fabless RF-IC design house, typically seen on 2.4GHz or Sub-1GHz wireless peripherals — wireless mice, keyboards, and gamepads, or embedded RF modules such as automotive remote-start systems and smart-grid meter readers — built around one of Amiccom's transceiver chips.

The company holds two full MA-L (/24) blocks in the IEEE registry, both registered to addresses in the Hsinchu area of Taiwan. A direct registry grep and a cross-check against Wireshark's the Wireshark manufacturer database both confirm the same two prefixes, with no additional MA-M or MA-S sub-blocks on file, and IEEE publishes no assignment date for either.

Separately, Amiccom itself was founded in November 2005 and listed on Taiwan's OTC GreTai Securities Market (ticker 5272, now the Taipei Exchange) in May 2013 — general corporate history, not an OUI registration date.

Amiccom's product line covers 2.4GHz, Sub-1GHz, and 5.8GHz RF transceivers and SoCs — parts such as the A7105, A7139, and A7149 are current, stocked parts at mainstream distributors LCSC and JLCPCB. Documented applications include wireless input peripherals, baby monitors, electronic toll tags, smart-grid meter reading, automotive remote-start and alarm systems, electronic shelf labels, and satellite LNB downconverters, per Amiccom's own site and a 2015 trade-press interview.

No CVE names Amiccom or its chips in the NVD as of an August 2026 keyword search, and no public device-fingerprint or packet-capture database was found pinning either prefix to an observed real-world device — that is an open Unknown, not a negative finding. Bastille's 2016 MouseJack disclosure targeted similar 2.4GHz wireless-HID dongles but named Nordic Semiconductor's radio chips, not Amiccom's, and the two should not be conflated.

Analyst note

a MAC beginning C4:FE:E2 or 18:7A:93 indicates Amiccom RF-transceiver silicon inside a wireless peripheral or embedded RF module, most plausibly a 2.4GHz/Sub-1GHz wireless input device or telemetry module; Amiccom sells chips rather than branded end products, so the specific device is set by the OEM, not by the registry entry
