USB5533B-5000JZXTR

Controllers Overview

The USB5533B-5000JZXTR 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, PHYBoost for selectable drive strength, and VariSense for programmable receiver sensitivity.

Controllers Feature Summary

• Supports battery charging emulation including CDP, DCP, Apple, Blackberry, and Chinese YD/T standards
• Integrates MultiTRAK technology to maintain consistent full-speed throughput across active downstream connections
• Includes configurable over-current detection and port power control on individual or ganged bases
• Features Vendor Specific Messaging support for firmware upload over USB

Controllers Applications

• Desktop and laptop computer expansion hubs
• Industrial control systems requiring multiple peripheral connections
• Consumer electronics devices needing high-speed data transfer capabilities

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product identification system to ensure correct package type and temperature range. Confirm that the -5000 firmware version aligns with project requirements, as it lacks Dynamic Charging Port features found in other variants. Cross-reference the datasheet revision history for any silicon errata applicable to this component.

Controllers Selection Notes

Select this model when three downstream ports are required alongside SuperSpeed connectivity. Ensure the design accommodates the QFN-64 package and provides a 25 MHz crystal or clock input. Verify that the host system supports the necessary configuration interfaces such as SPI or SMBus if custom descriptors or non-removable ports are needed.

Controllers Part Context

This component belongs to the USB5533B family of low-power hub controllers manufactured by Microchip Technology. It serves as a bridge between upstream host controllers and multiple downstream USB peripherals. The device distinguishes itself through integrated termination resistors and parallel operation of SuperSpeed and USB 2.0 controllers to prevent traffic interference.
