Dialog Semiconductor Hellas SA — 2 prefixes (MA-L)

A MAC address starting with 48:23:35 or 80:EA:CA identifies hardware carrying a Dialog Semiconductor Hellas SA network interface, most plausibly the wireless radio of a third-party OEM product built on Dialog's SmartBond Bluetooth Low Energy system-on-chip family rather than a Dialog-branded consumer device.

Dialog Semiconductor Hellas SA is the Athens, Greece design-center subsidiary of Dialog Semiconductor plc, a mixed-signal and IoT-connectivity semiconductor company. Renesas Electronics acquired Dialog Semiconductor in 2021, and the Athens entity now operates as "Dialog-Semiconductor Hellas SA, a Renesas company."

The IEEE registry lists two separate MA-L (24-bit) assignments to this registrant name — 48:23:35 and 80:EA:CA — each a standalone /24 block rather than a sub-allocation of a shared IEEE base. The two rows carry different Athens addresses; a plausible explanation is an office move between filings rather than a different company, though the sequence of which address is earlier is not independently confirmed.

No CVE, malware family, or botnet association is recorded for either prefix as of an August 2026 web search, though this reflects only what surfaced in that search rather than an exhaustive audit. IEEE's public OUI data publishes no assignment date for either block; any "registered" date shown by third-party lookup tools is a database artifact, not an IEEE fact.

Verified sample prefixes

48:23:35, 80:EA:CA (both MA-L, Dialog Semiconductor Hellas SA) [Confirmed] — the IEEE MA-L registry 482335, the IEEE MA-L registry 80EACA

Third-party date artifact

maclookup.app shows a "registered" date of 27 May 2014 and an "updated" date of 17 November 2015 for 80:EA:CA; these are maclookup.app's own database timestamps, not IEEE facts — IEEE publishes no registration date [Confirmed] — https://maclookup.app/macaddress/80EACA

Security context

no CVE, malware family, or botnet association found for either prefix as of an August 2026 search [Likely] — search outcome, no dedicated source page to cite for the negative

Analyst note

two independent MA-L grants under the same registrant name plus documented product/company context clear the bar for a substantive vendor entry — this is not a bare single-OUI shell
