Integrated Device Technology (Malaysia) Sdn. Bhd. — 40 prefixes (MA-L)

Integrated Device Technology (Malaysia) Sdn. Bhd. is the Penang, Malaysia manufacturing subsidiary of Integrated Device Technology, Inc. (IDT), a US semiconductor company whose acquisition by Renesas Electronics was announced in September 2018 and completed on March 30, 2019. The IEEE MA-L registry lists 40 distinct 24-bit OUI blocks assigned to this exact legal entity at the identical registered address — Phase 3, Bayan Lepas FIZ, Bayan Lepas, Penang, Malaysia — with no variant spellings across the matching rows, and no MA-M or MA-S assignments exist for this organization. A multi-OUI footprint of this size is itself a substance signal: it points to sustained, high-volume manufacturing activity rather than a single opportunistic registration. Corporate-registry sources (EMIS, Bloomberg) corroborate the same Penang address for the successor entity and describe a semiconductor-device manufacturing business (actuators, sensors, amplifiers, data converters). Following the Renesas acquisition, the Malaysia subsidiary was subsequently renamed Renesas Electronics (Penang) Sdn. Bhd., effective in the first half of 2020. IDT's parent product lines relevant to MAC-bearing hardware include PCIe system-interconnect switches and Ethernet/MII PHY interface ICs — the ICS1893BF datasheet, for example, documents OUI-related bits in its PHY Identifier register, consistent with networking-adjacent silicon manufactured at this facility. No IEEE assignment/registration date exists for any of these prefixes (IEEE's the IEEE MA-L registry publishes no date field), and no such date is asserted here.

Organization name (exact, IEEE MA-L)

"Integrated Device Technology (Malaysia) Sdn. Bhd." [Confirmed] — the IEEE MA-L registry

Registry / block class

MA-L only (24-bit OUI); no MA-M (the IEEE MA-M registry) or MA-S (the IEEE MA-S registry) assignments found [Confirmed] — the IEEE MA-M registry, the IEEE MA-S registry

Registered address (verbatim from registry)

Phase 3, Bayan Lepas FIZ, Bayan Lepas, Penang, MY 11900 [Confirmed] — the IEEE MA-L registry

Prefix count

40 MA-L assignments under this exact org name/address [Confirmed] — the IEEE MA-L registry (C84F0E, E4CC9D, 9C497F, 58ECED, 649829, A4F3E7, 2CB115, D055B2, 80D160, 782A79, 701BFB, F89910, CC51B4, CC9916, B8DB1C, D8452B, 1C9D3E, 689361, DCCC8D, FCEA50, D8D6F3, A42618, 907910, 8817A3, 803A0A, E80945, 101250, 7C6AF3, 509744, DC3757, 20163D, 18C19D, E8DE8E, 9CF029, 40B30E, 847F3D, 40F04E, A4B52E, 14E7C8, 2405F5)

Registration date

Unknown / not applicable — IEEE's public OUI registry publishes no assignment-date field; any third-party "date registered" value is a database artifact, not an IEEE fact [Confirmed] — the IEEE MA-L registry (header: Registry,Assignment,Organization Name,Organization Address)

IANA reference

Not applicable (IANA Reference is a port-registry field, not tracked for OUI/MAC vendor entries) [Confirmed]

Parent company / corporate lineage

Subsidiary of Integrated Device Technology, Inc. (IDT), acquired by Renesas Electronics (announced Sept 2018, completed March 30, 2019); subsidiary renamed Renesas Electronics (Penang) Sdn. Bhd. effective H1 2020 [Likely] — Renesas press releases (renesas.com), Wikipedia (IDT acquisition history)

Company substance / registered-entity corroboration

EMIS Malaysia and Bloomberg Markets profiles for "Renesas Electronics Penang Sdn. Bhd." confirm the same Bayan Lepas, Penang address; EMIS states an incorporation date of Dec 5, 1987 for the Penang entity (third-party corporate-registry aggregator, not a primary Malaysian company-registry source, not an OUI date) [Likely] — https://www.emis.com/php/company-profile/MY/Integrated_Device_Technology__Malaysia__SdnBhd_en_4260739.html, https://www.bloomberg.com/profile/company/7730216Z:MK

Device / product context

IDT (parent) manufactures PCIe system-interconnect switches and Ethernet/MII PHY interface ICs; the ICS1893BF datasheet documents OUI-related bits in its PHY Identifier register, consistent with networking-adjacent silicon [Likely] — https://www.renesas.com/en/document/dst/1893bfbk-datasheet, https://www.renesas.com/en/document/whp/idt-pcie-system-interconnect-solutions

Current live vendor page

mac/vendor/integrated-device-technology-malaysia-sdn-bhd/index.html already renders all 40 OUI prefix links and the IEEE address block; correctly noindex,follow per per-entry convention [Confirmed]

Company status

Original legal entity folded into Renesas via rename; no standalone active "IDT Malaysia" entity remains post-2020 [Likely] — Renesas press release on subsidiary rename
