USB3503A-1-GL-TR

Controllers Overview

The USB3503A-1-GL-TR is a low-power, USB 2.0 hub controller featuring an HSIC upstream port and three downstream ports. It operates within a voltage range of 2.8 V to 3.6 V with a typical standby current of 1 µA. The device supports High Speed (480 Mb/s), Full Speed (12 Mb/s), and Low Speed (1.5 Mb/s) data rates. It utilizes a 25-pin WLCSP package measuring 1.97 mm x 1.97 mm. Operating temperatures range from -40°C to +85°C.

Controllers Feature Summary

• Integrated MultiTRAK technology providing dedicated transaction translators per port for consistent full-speed throughput.
• Configurable port mapping and disable sequencing via PortMap logic.
• Programmable signal drive strength and receiver sensitivity for improved signal integrity in compromised environments.
• Supports customizable vendor ID, product ID, and string descriptors through serial I2C interface.

Controllers Applications

• Mobile Phones
• Tablet Computers
• Ultra Mobile PCs
• Digital Still Cameras
• Gaming Consoles

Controllers Procurement Notes

Verify the specific suffix 'A-1-GL-TR' against the manufacturer's latest documentation to confirm pinout compatibility and revision status. Ensure the receiving system provides the required reference clock frequencies and power supply configurations as specified in the electrical characteristics section of the datasheet.

Controllers Selection Notes

Select this component when a compact footprint is required for mobile applications due to its WLCSP packaging. Consider the integrated regulators and internal termination resistors which reduce external BOM requirements. Verify that the host system can support the HSIC upstream interface and provide the necessary reference clock inputs for proper operation.

Controllers Part Context

This part belongs to the USB3503 series of high-speed hub controllers optimized for portable devices. It shares functional similarities with other members like the USB3503T-I/ML but differs in package type, utilizing a 25-ball WLCSP instead of the SQFN variant. The series focuses on minimizing power consumption and board space for battery-operated systems.

Controllers Replacement Considerations

Direct substitutes include other Microchip USB3503 variants such as USB3503T-I/ML, provided the package difference between WLCSP and SQFN is accommodated by the PCB design. Cross-package replacements require careful review of pin definitions and thermal management strategies.
