Key Features
- AEC-Q100 Grade 1 automotive qualification for reliable operation in harsh in-vehicle environments
- USB 2.0 high-speed 480 Mbps ULPI interface reduces signal pin count between processor and PHY
- Compact QFN package with wide supply voltage tolerance enables integration in space-constrained automotive ECUs
Applications
TUSB1210-Q1 is designed for automotive infotainment head units, in-vehicle USB hubs, and telematics control units requiring AEC-Q100 Grade 1 qualified USB 2.0 connectivity operating across the -40°C to 125°C temperature range. Its ULPI interface connects directly to automotive-grade application processors and SoCs that lack an integrated USB PHY, enabling high-speed 480 Mbps data transfer for media playback, software updates, and CarPlay or Android Auto implementations. The compact QFN footprint also suits industrial gateway modules and communications equipment needing a standalone USB 2.0 transceiver.

Frequently Asked Questions
What USB data rates does TUSB1210-Q1 support, and which ULPI pin count does it expose?
TUSB1210-Q1 supports USB 2.0 high-speed at 480 Mbps and full-speed at 12 Mbps through a standard 8-bit ULPI interface, which requires only 12 signal pins to connect to the host processor instead of a full 60-pin UTMI bus. This reduced pin count simplifies PCB routing and shortens layout time for automotive SoC designs that expose a ULPI port.
How does AEC-Q100 Grade 1 qualification affect TUSB1210-Q1 suitability for automotive applications?
AEC-Q100 Grade 1 qualification certifies that TUSB1210-Q1 is tested and guaranteed to operate reliably across an ambient temperature range of -40°C to 125°C, covering typical underhood and passenger-cabin automotive thermal extremes. This qualification is required by Tier-1 automotive suppliers for components in infotainment, telematics, and body-control ECUs where consumer-grade parts would be rejected.
In a telematics control unit design, when would TUSB1210-Q1 be chosen over a processor with integrated USB PHY?
Application processors with integrated USB PHYs often carry only consumer-grade temperature ratings up to 85°C, whereas TUSB1210-Q1 extends reliable USB 2.0 operation to 125°C. For telematics units requiring AEC-Q100 Grade 1 compliance and a processor that lacks a qualified on-chip PHY, TUSB1210-Q1 provides the necessary external 480 Mbps transceiver without compromising automotive qualification standards.
What package does TUSB1210-Q1 use, and how does it compare to larger USB PHY packages in board space?
TUSB1210-Q1 is available in a compact Quad Flat No-Lead (QFN) package that occupies significantly less PCB area than older TQFP USB PHY packages while providing improved thermal dissipation through the exposed pad. In automotive ECUs where board space is limited and assembly processes favor lead-free reflow soldering, the QFN form factor reduces both footprint and assembly defect rates compared to fine-pitch leaded packages.
