USB5533B-6080JZXTR

Controllers Overview

The USB5533B-6080JZXTR is a 3-port SuperSpeed/Hi-Speed configurable 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, 8 KB RAM, 32 KB ROM, and 8 kbit OTP memory. It operates on a single 25 MHz crystal or clock input and features a 64-pin HVQCCN package.

Controllers Feature Summary

• Supports battery charging emulation for popular devices including Apple, Blackberry, and Chinese standards
• Configurable via internal default settings, OTP ROM, SPI ROM, or SMBus interface
• Includes MultiTRAK technology for dedicated transaction translators per port
• Features PHYBoost and VariSense for improved USB 2.0 signal integrity

Controllers Applications

• Desktop and laptop computer expansion hubs
• Industrial control systems requiring multiple USB connections
• Consumer electronics docking stations

Controllers Procurement Notes

Verify the specific -6080 suffix to ensure availability of the Dynamic Charging Port feature and Global Suspend power optimization. Confirm package type matches the 64-pin HVQCCN requirement. Check for RoHS compliance status as indicated in official documentation.

Controllers Selection Notes

Select this model over the -5000 variant if dynamic charging port disable functionality or lower global suspend power consumption is required. Ensure the design accommodates the 64-pin QFN footprint and provides necessary external components for the 25 MHz clock source.

Controllers Part Context

This component belongs to the Microchip USB5533B family of low-power, configurable hub controllers. It serves as a bridge between host systems and multiple USB peripherals, supporting all defined USB operating speeds from Low-Speed to SuperSpeed within a compact integrated circuit.

Controllers Replacement Considerations

The USB5533B-5000JZXTR is a related variant but lacks the Dynamic Charging Port feature and has different buffer types. Verify functional equivalence regarding power management and configuration requirements before substitution.

Controllers FAQ

What distinguishes the -6080 version from the -5000 version?

The -6080 version includes the Dynamic Charging Port feature, utilizes an IPU buffer type for the TRST/DYNCPDIS_N pin, and offers significantly lowered Global Suspend power consumption compared to the -5000 version.

How is the USB5533B configured for operation?

Configuration is supported through internal default settings, an on-chip One-Time Programmable (OTP) ROM, an external SPI ROM, or via an SMBus interface.

Does the device support simultaneous SuperSpeed and USB 2.0 traffic?

Yes, the SuperSpeed hub controller operates in parallel with the USB 2.0 hub controller, ensuring that 5 Gbps SuperSpeed data transfers are not affected by slower USB 2.0 traffic.
