Controllers datasheet and documents for USB5534-JZX

USB5534-JZX

Controllers Overview

The USB5534-JZX is a 4-port SuperSpeed USB 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 on-chip 8051 microcontroller, 8 K RAM, 32 K ROM, and 8 kbit OTP ROM for configuration via JTAG or SPI. Operating voltages include 1.25 V and 3.3 V. It features a 64-pin QFN package measuring 9.1 x 9.1 mm with a maximum height of 0.95 mm. The operational temperature range spans from 0°C to +70°C.

Controllers Feature Summary

Parallel operation of independent SuperSpeed and USB 2.0 controllers prevents slower traffic from affecting 5 Gbps transfers.
Integrated 8051 microcontroller manages GPIOs, VBUS control, and LED modes for OEM differentiation.
Supports battery charging emulation including China Charger, legacy protocols, and USB-IF standards when headless.
Includes PHYBoost and VariSense features to optimize signal integrity and receiver sensitivity.

Controllers Applications

Mobile PC docking stations
LCD monitors and televisions
Portable expansion hubs
PC motherboards
Set-top boxes and DVR/PVR devices

Controllers Procurement Notes

Verify component authenticity through authorized Microchip Technology channels. Confirm RoHS compliance and halogen-free status per IEC61249-2-21 requirements. Ensure proper ESD handling during storage and assembly. Validate firmware compatibility with target operating systems before integration.

Controllers Selection Notes

Select this component for designs requiring simultaneous high-speed and legacy USB connectivity. The integrated microcontroller reduces external logic requirements. Verify power supply constraints match the specified 1.25 V and 3.3 V rails. Consider the 64-pin QFN footprint for PCB layout planning.

Controllers Part Context

Manufactured by Microchip Technology under the SMSC brand lineage, this controller belongs to the USB5534 family. It serves as a bridge between host systems and multiple downstream USB peripherals. The device consolidates hub functionality into a single low-power package suitable for space-constrained electronics.
