Synaptics Incorporated is a US fabless silicon maker (San Jose, CA) that holds IEEE-verified blocks under registrant "Synaptics, Inc": MA-L 80:01:5C, 90:CC:24, and B4:02:F2, plus the MA-M /28 sub-allocation 18:C3:F4:50/28. Synaptics is a mixed case at the network layer: its classic touchpads, touchscreen controllers, fingerprint sensors, display drivers (DDIC), and audio/voice silicon carry no network MAC, but its wireless-connectivity SoCs do. Those connectivity parts came largely from acquisitions — Conexant and Marvell's multimedia business (2017) and Broadcom's wireless IoT connectivity business (announced 2020-07-07, roughly $250 million, spanning Wi-Fi 6/6E, Bluetooth 5.2, and GPS L5) — and they appear in IoT, smart-home, and embedded Wi-Fi devices. The key analyst point is to read both sides: touch silicon = no MAC, connectivity SoCs = chipset-OUI. For triage, a Synaptics OUI on the network is a Wi-Fi/BLE connectivity-SoC device (often an IoT/smart-home/embedded product using a former-Broadcom radio), NOT a laptop touchpad or fingerprint reader — those parts are not networked.
- IEEE assignment
- registrant "Synaptics, Inc" — MA-L 80:01:5C, 90:CC:24, B4:02:F2; MA-M 18:C3:F4:50/28 [Confirmed] — IEEE MA-L/MA-M registry
- Registry / block size
- 3 MA-L blocks + 1 MA-M /28 (18:C3:F4:50/28, a sub-allocation under the shared 18:C3:F4 MA-M base) [Confirmed] — IEEE MA-L/MA-M registry
- HQ / country
- San Jose, CA (historically 1251 / 1109 McKay Dr, San Jose, CA 95131) [Likely] — business directories (not the IEEE page body)
- Company status
- active (fabless); acquired Conexant + Marvell multimedia (2017) and Broadcom's wireless IoT connectivity business (announced 2020-07-07, ~$250M) [Confirmed] — Synaptics press release
- Device types
- touchpads, touchscreen controllers, fingerprint sensors, display drivers (DDIC), audio/voice (NO network MAC) PLUS Wi-Fi/Bluetooth/connectivity SoCs (post-Broadcom-IoT, legacy Conexant/Marvell — these DO carry MACs) [Confirmed] — synaptics.com
- Notable products
- laptop touchpads, fingerprint sensors, DDIC; Wi-Fi 6/6E + BT 5.2 connectivity SoCs
- Verified prefixes
- 80:01:5C, 90:CC:24, B4:02:F2 (MA-L); 18:C3:F4:50/28 (MA-M) [Confirmed] — IEEE MA-L/MA-M registry
- Special note
- MIXED case — classic Synaptics touch/fingerprint/display silicon never produces a MAC, but its wireless-connectivity SoCs do. A Synaptics OUI therefore indicates a connectivity-SoC-based device, not a touchpad. Connectivity lineage from Broadcom (covered), Conexant, Marvell wireless. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]

- Analyst note
- If you see a Synaptics OUI on the network, it is a Wi-Fi/BLE connectivity-SoC device (often an IoT/smart-home/embedded product using a former-Broadcom radio), NOT a laptop touchpad or fingerprint reader — those parts are not networked.
