USB5534B-4100JZX

Controllers Overview

The USB5534B-4100JZX is a 4-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 managing GPIOs, VBUS, and hub signals, alongside 8 KB RAM and 32 KB ROM. Configuration is supported via internal defaults, on-chip OTP ROM, external SPI ROM, or SMBus. It operates within a temperature range of 0°C to 70°C in a 64-pin QFN package measuring 9 x 9 mm.

Controllers Feature Summary

• Supports battery charging protocols including USB-IF Battery Charging rev. 1.2 (DCP & CDP) and emulation for Apple, Blackberry, and Chinese YD/T standards.
• Features MultiTRAK technology implementing dedicated Transaction Translators per port to maintain consistent full-speed data throughput.
• Includes PHYBoost and VariSense features for selectable drive strength and programmable receiver sensitivity levels.
• Provides Vendor Specific Messaging support for firmware upload over USB.

Controllers Applications

• Desktop and laptop computer expansion
• Industrial control systems
• Consumer electronics hubs

Controllers Procurement Notes

Verify component authenticity through authorized Microchip Technology channels. Confirm that the specific ordering suffix matches the required operational temperature range and packaging format. Ensure compliance with relevant environmental directives before integration into final assemblies.

Controllers Selection Notes

Select this model when four downstream ports are required with integrated SuperSpeed capabilities. Consider the USB5534Bi variant if operation below 0°C is necessary. Verify system power requirements against the single supply voltage specifications and ensure adequate thermal dissipation for the exposed pad.

Controllers Part Context

This component belongs to the SMSC USB5534B family of low-power hub controllers. Originally developed by Standard Microsystems Corporation, the product line was acquired by Microchip Technology. The series provides configurable solutions for high-speed data transfer applications requiring multiple peripheral connections.

Controllers Replacement Considerations

The USB5534Bi-4100JZX serves as a direct functional substitute with an extended industrial temperature range of -40°C to 85°C. Other models in the USB5534B series may offer different configuration options but require verification of pin compatibility and electrical characteristics.
