STULPI01ATBR

Drivers, Receivers, Transceivers Overview

The STULPI01ATBR is a high-speed USB 2.0 transceiver compliant with ULPI and OTG specifications, providing a complete physical layer solution for USB host, device, or OTG dual-role cores. It interfaces with USB ASICs via a 12-pin digital interface and includes VBUS comparators, an ID line detector, differential drivers/receivers, and a full ULPI register map. The device supports 480 Mb/s High-speed, 12 Mb/s Full-speed, and 1.5 Mb/s Low-speed modes. It operates on a single supply voltage ranging from +3 V to +4.5 V and features integrated dual voltage regulators for stable 3.3 V and 1.2 V internal supplies. The component is housed in a μTFBGA36 RoHS package and functions within a temperature range of -40 °C to 85 °C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'TBR' against the manufacturer's official documentation to confirm tape-and-reel packaging details and any minor manufacturing variations. Ensure the ordering part number matches the exact active status and package type listed in the current datasheet to avoid compatibility issues with existing designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a standard ULPI 1.1 interface is required for connecting an ASIC to a USB physical layer. It is appropriate for designs needing integrated VBUS comparison and ID line detection without external discrete components. Consider the single-supply voltage range and integrated regulators when designing the power architecture for mobile or portable systems.

Drivers, Receivers, Transceivers Part Context

The STULPI01 series serves as a physical layer bridge between USB controllers and the USB bus. The STULPI01ATBR variant specifically denotes the surface-mount version in the μTFBGA36 package. This family enables designers to implement USB 2.0 compliance in system-on-chip architectures while minimizing board space and component count through high integration.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify pin-to-pin compatibility and electrical parameter alignment before considering alternative transceivers from other manufacturers.
