USB5533BI5000JZXTR

Controllers Overview

The USB5533BI5000JZXTR is a 3-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 8 KB RAM and 32 KB ROM. Configuration is supported via internal default settings, on-chip OTP ROM, external SPI ROM, or SMBus. It features MultiTRAK technology for dedicated transaction translators per port and supports battery charging protocols including CDP and DCP.

Controllers Feature Summary

• Supports simultaneous operation of SuperSpeed and USB 2.0 controllers to prevent data transfer interference.
• Includes programmable drive strength and receiver sensitivity controls for signal integrity optimization.
• Provides configurable downstream ports with individual power control and over-current detection capabilities.

Controllers Applications

• Desktop computer expansion hubs
• Portable docking stations
• Industrial control system interfaces

Controllers Procurement Notes

Verify the specific firmware revision suffix matches the required feature set, as variants like -6080 include distinct Dynamic Charging Port functions not present in the -5000 version. Confirm package availability and lead times directly with authorized Microchip Technology distributors or sales offices prior to ordering.

Controllers Selection Notes

Select this component when a low-power, three-port USB 3.0 solution is required with flexible configuration options. Ensure the design accommodates the QFN-64 package and provides a 25 MHz crystal or clock input. Evaluate whether the -5000 firmware variant meets all application requirements regarding dynamic charging support before finalizing the part number.

Controllers Part Context

This device belongs to the USB5533B family of hub controllers manufactured by Microchip Technology. It serves as a bridge between upstream host connections and multiple downstream USB peripherals. The family includes variants differentiated primarily by firmware revisions that enable specific hardware features such as dynamic charging port disable functions.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Microchip Technology for current alternative recommendations based on specific pinout and functional compatibility requirements.

Controllers FAQ

How does the USB5533B handle simultaneous SuperSpeed and USB 2.0 traffic?

The device operates its SuperSpeed hub controller in parallel with the USB 2.0 hub controller, ensuring that 5 Gbps SuperSpeed data transfers remain unaffected by slower USB 2.0 traffic.

What configuration methods are supported for customizing the hub?

The USB5533B can be configured using internal default settings, an on-chip One-Time Programmable (OTP) ROM, an external SPI ROM, or via an SMBus interface.

Does the USB5533BI5000JZXTR support dynamic charging port disable?

No, the Dynamic Charging Port feature and the related DYNCPDIS_N pin function are only available on the -6080 device version, not the -5000 version.
