USB5534B-5000JZXTR

Controllers Overview

The USB5534B-5000JZXTR is a 4-port SuperSpeed/Hi-Speed configurable hub controller compliant with the USB 3.0 Specification. It supports data rates of 5 Gbps (SuperSpeed), 480 Mbps (Hi-Speed), 12 Mbps (Full-Speed), and 1.5 Mbps (Low-Speed). The device integrates an embedded 8051 microcontroller, 32 KB ROM, 8 KB RAM, and 8 kbit OTP ROM. It operates on single 1.25 V and 3.3 V supplies, utilizes a 64-pin QFN package measuring 9.1 x 9.1 mm, and requires a 25 MHz crystal or clock input.

Controllers Feature Summary

• Supports simultaneous operation of independent USB 3.0 and USB 2.0 controllers to prevent bandwidth contention between SuperSpeed and Hi-Speed traffic.
• Enables per-port battery charging emulation for CDP, DCP, Apple, Blackberry, and YD/T standards without external hardware.
• Allows configuration via internal default settings, on-chip OTP ROM, external SPI ROM, or SMBus interface.
• Includes MultiTRAK technology providing dedicated Transaction Translators for each port to maintain Full-Speed throughput.

Controllers Applications

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

Controllers Procurement Notes

Verify the specific firmware version suffix '-5000' against design requirements, as it lacks Dynamic Charging Port features found in the '-6080' variant. Confirm that the 64-pin QFN package footprint matches the PCB layout. Ensure the system provides the required 1.2V and 3.3V power rails and a 25MHz clock source before integration.

Controllers Selection Notes

Select this component when a low-power, 4-port USB 3.0 solution with integrated charge management is required. The -5000 firmware version is suitable for standard applications not requiring dynamic charging port disable functionality. Consider the -6080 version if global dynamic charging control via the DYNCPDIS_N pin is necessary for the specific application.

Controllers Part Context

This part belongs to the Microchip USB5534B family of USB 3.0 hub controllers. It shares the same silicon and physical package as the USB5534B-6080JZXTR but differs in firmware capabilities, specifically regarding dynamic charging port support and power consumption characteristics in global suspend mode.

Controllers Replacement Considerations

The USB5534B-6080JZXTR is a compatible alternative within the same family. Verify that the additional Dynamic Charging Port features of the -6080 variant do not conflict with existing board designs or software configurations.
