Abatron AG — 00:0C:01 (MA-L)

Abatron AG was a Swiss engineering firm, registered to the single IEEE MA-L block 00:0C:01 at Lettenstrasse 9, Rotkreuz, CH-6343, Switzerland. Founded in 1985, the company built its business around one thing: hardware-level debug interfaces for embedded systems. Its BDM/JTAG "Background Debug Interface" product line — the BDI1000, BDI2000, and later BDI3000 — let engineers set breakpoints, read and write target memory, and program flash on target boards during firmware and board-support-package development. The BDI3000 communicated with the host over Ethernet (up to 32 Mbit/s per the vendor's own documentation), which is why the unit carried this OUI at all: these are lab and bench tools for embedded developers, not networking infrastructure in the router or switch sense. Abatron's customers spanned automotive, telecom, industrial automation, medical instrumentation, and military and aerospace electronics. The company wound down operations in 2015 after roughly thirty years, and entered voluntary liquidation in February 2019; the abatron.ch domain is now maintained by SEGGER as a documentation archive that preserves the BDI manuals. Only one OUI is registered to this organization, but the corroborating device context — named hardware products, published specifications, third-party reseller listings, and a successor preserving the documentation — puts it well beyond a bare shell registration. Note the identification caveat common to all vendor OUIs: a globally-administered 00:0C:01 address reliably points to genuine Abatron BDI hardware, but the low production volume and the company's discontinuation mean these addresses are rare in the wild.

IEEE assignment

00:0C:01 → Abatron AG, MA-L block [Confirmed] — IEEE MA-L (local cached the IEEE MA-L registry; corroborated via maclookup.app, hwaddress.com, cleancss.com)

Registry / block size

MA-L (24-bit OUI). Single block only — no MA-M or MA-S rows for this org in the cached registry (the IEEE MA-M registry / the IEEE MA-S registry). [Confirmed] — IEEE MA-L. NOTE: IEEE publishes NO assignment/registration date; any "date registered" from third-party tools is a database artifact, not an IEEE fact.

HQ / country

Lettenstrasse 9, Rotkreuz, CH-6343, Switzerland (CH) (registry address, registry-native formatting) [Confirmed] — IEEE MA-L

Company status

defunct — wound down 2015 (founded 1985, ~30 years operating), voluntary liquidation February 2019; abatron.ch now a SEGGER-hosted documentation archive [Confirmed] — abatron.ch

Device types

hardware debug interfaces (BDM/JTAG in-circuit debuggers) for embedded systems — BDI1000, BDI2000, BDI3000 product line [Confirmed] — abatron.ch/products, BDI3000 brochure/manuals

Usage context

embedded-systems engineers use these for hardware-level debugging (breakpoints, memory access, flash programming) of target boards during firmware/BSP development, historically across automotive, telecom, industrial automation, medical, and military/aerospace sectors; professional lab equipment, not end-user/enterprise production-network gear

[Likely] — abatron.ch, BDI3000 product announcement (single-vendor sourcing for sector list)

Security context

no findable CVEs, advisories, or abuse/threat-intel tied to OUI 00:0C:01 or the BDI line in searches performed. Reported as an honest null (absence of findings), consistent with a niche, discontinued, low-volume tool — NOT confirmed absence of any historical issue. [Unknown] — no source

Date caveat

maclookup.app displays "registered 07 February 2003" / "last update 17 November 2015" for this OUI. These are third-party DATABASE ARTIFACTS, NOT IEEE facts — not recorded as an authoritative allocation date. [Confirmed] — maclookup.app

IANA reference

not applicable — OUI/MAC-vendor registrations are an IEEE Registration Authority matter, no IANA reference exists; left blank per no-fabrication rule.

Related entity

SEGGER (active, separate company) hosts the abatron.ch archive of BDI documentation; per the site's own framing this is domain/content preservation, not a confirmed acquisition of Abatron's assets or OUI. [Likely] — abatron.ch

Analyst note

a globally-administered 00:0C:01 address identifies genuine Abatron BDI debug hardware; but this is a single low-volume block from a company defunct since 2019, so such addresses are rare on live networks.
