USB5534B-6080JZXTR

Controllers Overview

The USB5534B-6080JZXTR is a 4-port SuperSpeed/Hi-Speed hub controller compliant with the USB 3.0 Specification. It supports 5 Gbps SuperSpeed, 480 Mbps Hi-Speed, 12 Mbps Full-Speed, and 1.5 Mbps Low-Speed signaling. The device integrates an embedded 8051 microcontroller with 32 KB ROM, 8 KB RAM, and 8 kbit OTP memory. It features four downstream ports with integrated terminations and pull-up/pull-down resistors. Configuration is supported via internal default settings, on-chip OTP ROM, external SPI ROM, or SMBus interface.

Controllers Feature Summary

• Supports battery charging protocols including CDP, DCP, and emulation for specific mobile devices
• Includes MultiTRAK technology for dedicated transaction translators per port
• Features PHYBoost and VariSense for signal integrity optimization
• Configurable over-current sensing and port power control

Controllers Applications

• Desktop and laptop computer expansion hubs
• All-in-one printers and multifunction devices
• Industrial automation controllers requiring multiple USB connections

Controllers Procurement Notes

Verify the -6080 suffix indicates the presence of the Dynamic Charging Port feature and specific pin buffer types compared to other variants. Confirm package type matches design requirements. Check for RoHS compliance status in official documentation before finalizing procurement specifications.

Controllers Selection Notes

Select this model when four downstream ports are required with independent power control capabilities. Ensure the application utilizes the -6080 firmware variant if dynamic charging port disable functionality is needed. Verify that the system provides a 25 MHz clock source or crystal connection for proper PLL operation.

Controllers Part Context

This component belongs to the USB5534B family of low-power configurable hub controllers. It operates alongside the USB 2.0 hub controller to ensure SuperSpeed transfers remain unaffected by slower traffic. The device is designed for applications requiring high data throughput and flexible configuration options.

Controllers Replacement Considerations

The USB5534B-5000JZXTR is a related variant within the same family. Differences include the absence of the Dynamic Charging Port feature and distinct TRST/DYNCPDIS_N pin buffer types. Evaluate functional requirements against these specific hardware differences before substitution.
