STULPI01BTBR Descripción general
A USB 2.0 transceiver (also called a USB PHY) is the analog front-end of a USB system, handling the high-speed differential signaling on the DP/DM lines, the low-/full-speed termination, the 1.5 kohm pull-up for device detection, the 15 kohm pull-down on the host side, the OTG session-request comparator, and the charge-pump for VBUS drive. The STULPI01B sits in the hierarchy: USB transceiver (PHY) -> USB interface IC -> interface and transceiver -> semiconductor, and is typically paired with an application processor that implements the upper protocol layers over the ULPI link.
Key features include 480 Mbps High-Speed (HS), 12 Mbps Full-Speed (FS), and 1.5 Mbps Low-Speed (LS) operation; integrated 45 ohm Hi-Speed termination and switching between HS and FS/LS terminations; 8-bit SDR ULPI interface operating at 60 MHz; integrated charge pump for OTG VBUS pulsing; on-chip pull-up/pull-down resistors for DP/DM; host, device, and OTG dual-role modes selectable via the ULPI ID pin; I/O supply 1.8 V to 3.3 V; and a 3.0 V to 4.5 V analog supply rail. The chip supports suspend, resume, remote wakeup, and chirp handshake generation required for HS negotiation.
Technically the PHY uses a precise 480 MHz PLL locked to the 60 MHz ULPI clock, an HS current-mode driver with controlled edge rates for USB IF compliance, a 3.3 V tolerant ULPI link, and on-die ESD protection on the DP/DM lines. By outsourcing the analog and analog-digital mixed-signal PHY to the STULPI01B, designers can implement the USB digital controller in their standard-cell ASIC or FPGA fabric without requiring an expensive analog process node, which is why this architecture is dominant in mobile, set-top, and automotive infotainment silicon.
Typical applications include USB OTG dual-role ports in smartphones, tablets, and portable media players, USB device ports in printers and storage, USB host capability in set-top boxes and automotive head units, USB-to-UART bridge ASICs, and embedded computing platforms that add USB to an FPGA or microcontroller without an internal PHY. The BGA package and small footprint suit 4-layer mobile mainboards where board area is at a premium.
When laying out a board using the STULPI01BTBR, place the device as close as possible to the USB connector, keep DP/DM traces matched to 90 ohm differential impedance, and provide a clean analog 3.3 V supply decoupled with a 100 nF + 4.7 uF combination within 5 mm of the VCC pin. The ULPI bus to the SoC should be length-matched and routed over a continuous reference plane to preserve 60 MHz SDR timing margin.

Aplicaciones típicas
STULPI01BTBR es adecuado para 6 aplicacións: USB OTG Dual-Role Port in Smartphones, USB Device Port in Set-Top Boxes, USB Host in Automotive Infotainment, USB-to-UART Bridge ASIC for Embedded Boards, USB FS Host for Microcontroller Boards, USB Device for Printers, Cameras and External Storage.
USB OTG Dual-Role Port in Smartphones
The STULPI01BTBR is well matched to smartphone OTG ports because it implements the full ULPI bridge from the application processor to the USB Type-A or Type-C connector at 480 Mbps High-Speed, with the integrated charge pump driving VBUS for Host-role operation without external components. Its 36-TFBGA 3.5 x 3.5 mm footprint is small enough to fit alongside cellular RF and power-management ICs. Quote by supplier VBUS_VALID/DRVVBUS lines directly to the SoC, then pair with a companion CCG3PA Type-C controller for port-detection and power-delivery negotiation.
Recomendado
USB Device Port in Set-Top Boxes
For set-top-box designs that need a single USB-A device-mode port for external storage or USB peripherals, the STULPI01BTBR provides HS/FS/LS termination on-chip and chirp-handshake generation for HS negotiation, allowing the SoC to operate in device mode over a 60 MHz 8-bit SDR ULPI bus. The 1.8 V to 3.3 V VCC_IO range lets it connect directly to a 1.8 V application processor without level shifters. Place the PHY within 5 mm of the connector and match DP/DM to 90 ohm differential impedance for USB-IF compliance.
Recomendado
USB Host in Automotive Infotainment
Automotive head units commonly use the STULPI01BTBR to expose USB-A host ports to the infotainment SoC, since the ST ULPI line is offered with automotive qualification programs. The transceiver's -40 C to +85 C operating range covers cabin environments, and the integrated charge pump removes the need for an external VBUS driver. Pair the PHY with an automotive-grade companion controller for USB Type-C, and place ESD/EMI protection on the connector side per AEC-Q100 system-level guidelines.
Recomendado
USB-to-UART Bridge ASIC for Embedded Boards
Use the STULPI01BTBR as the PHY half of a USB-to-UART bridge inside an FPGA or ASIC design: the ULPI port connects to a soft ULPI controller in the FPGA fabric, which converts to UART or CDC-ACM for an industrial or IoT endpoint. The 480 Mbps HS capability exposes the full USB bus to the host, and the 12-pin ULPI link keeps FPGA pin count low. Pair with a low-power MCU that handles the high-level bridge protocol, and add a 24 MHz crystal or LVCMOS clock source to feed the ULPI clock reference.
Recomendado
USB FS Host for Microcontroller Boards
Many microcontroller-class designs running at Full-Speed use the STULPI01BTBR strictly in FS mode to expose host capability to a board that lacks an internal USB PHY. With the PHY handling FS 1.5 kohm pull-up and 15 kohm pull-down on chip, the host MCU only needs a software ULPI stack. The 36-TFBGA package complements small PCB footprints; pair the PHY with a level shifter only if the MCU I/O voltage exceeds 3.3 V, otherwise VCC_IO ties directly to the MCU rail.
Recomendado
USB Device for Printers, Cameras and External Storage
Printers, IP cameras, and external-storage enclosures use the STULPI01BTBR as the device-side PHY because the integrated 1.5 kohm pull-up on DP simplifies the device-detection circuit and avoids an external resistor. The 480 Mbps HS capability is valuable for image transfers and high-throughput storage, and the 1.8 V to 3.3 V VCC_IO lets the PHY talk directly to a low-power companion SoC. Connect DP/DM straight to the USB connector with matched differential traces and a common-mode choke for EMI mitigation.

Notas de diseño
Place the STULPI01BTBR within 5 mm of the USB connector and route DP/DM as a 90 ohm differential pair with continuous ground reference on the layer below. Keep the pair length-matched within 0.5 mm to preserve HS eye-mask compliance; an unmatched pair causes data-dependent jitter and may fail USB-IF certification. Use a common-mode choke on DP/DM at the connector side to suppress EMI from the host port.
Decouple the 3.3 V analog VCC with a 100 nF X7R ceramic plus a 4.7 uF bulk capacitor placed within 3 mm of the BGA ball. The 1.8 V to 3.3 V VCC_IO supply should have its own 100 nF decoupling cap to suppress ULPI-link switching noise; tie VCC and VCC_IO grounds together at a single point to avoid ground loops that disturb the PLL.
Do not leave the RESETB pin floating; it must be driven by the SoC or pulled to a controlled rail with a 10 kohm pull-up and a small decoupling cap. Verify the ID pin state at boot to correctly enter Host, Device, or OTG dual-role mode; a floating ID pin can cause enumeration failures in OTG applications.
