Texas Instruments holds exactly 385 MA-L prefixes registered as "Texas Instruments" at 12500 TI Blvd, Dallas, TX — by far the largest allocation in this batch (per maclookup.app's IEEE-sourced tally). Verified samples include 60:64:05, F8:30:02, 40:2E:71, 88:C2:55, and 34:15:13. These OUIs appear on Wi-Fi/Bluetooth/Zigbee chipsets (the CC-series and SimpleLink families), embedded/IoT silicon, and processors — TI silicon carries the burned-in MAC on IoT and embedded devices. The key analyst point is the chipset pattern: a TI OUI on a network usually identifies a device built on a TI Wi-Fi/Zigbee/BT chip regardless of brand — the same chipset-OUI flag as Espressif or Realtek — and the CC2xxx/CC3xxx SimpleLink wireless MCUs are very common in IoT and Zigbee/Thread devices. For triage, a TI OUI typically flags an IoT/embedded endpoint built on a TI wireless MCU (a Zigbee/Thread/BLE/Wi-Fi sensor or module), so classify it as embedded/IoT silicon rather than a TI-brand consumer device.

- Special note
- A TI OUI usually identifies a device built on a TI Wi-Fi/Zigbee/BT chip REGARDLESS of brand — a chipset-OUI flag like Espressif/Realtek. CC2xxx/CC3xxx SimpleLink wireless MCUs are very common in IoT/Zigbee. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
- Related vendors
- none significant (silicon supplier to many brands)
- Analyst note
- A TI OUI typically flags an IoT/embedded endpoint built on a TI wireless MCU — common on Zigbee/Thread/BLE/Wi-Fi sensors and modules. Classify as embedded/IoT silicon, not as a TI-brand consumer device.
