USB5534-JZX-TR

Controllers Overview

The USB5534-JZX-TR is a 4-port SuperSpeed USB hub controller compliant with the USB 3.0 specification. It supports data rates of 5 Gbps, 480 Mbps, 12 Mbps, and 1.5 Mbps. The device integrates an embedded 8051 microcontroller with 32 K ROM and 8 K RAM for firmware execution. Configuration is managed via on-chip OTP ROM or external SPI ROM. It operates within a temperature range of 0°C to +70°C and utilizes a 64-pin QFN package measuring 9x9 mm.

Controllers Feature Summary

• Parallel operation of SuperSpeed and USB 2.0 controllers prevents slower traffic from affecting 5 Gbps transfers
• Integrated 8051 microcontroller manages GPIOs, VBUS control, and hub signals
• Supports battery charging emulation including China Charger and legacy protocols when headless
• Firmware-controlled LED modes indicate port capability and data activity

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 the component against the official SMSC datasheet revision 0.1 (dated 01-11-11) to confirm pinout compatibility and electrical specifications. Ensure the supplier provides documentation verifying RoHS compliance and halogen-free status per IEC61249-2-21 standards before finalizing acquisition.

Controllers Selection Notes

Select this component for designs requiring independent management of SuperSpeed and USB 2.0 traffic paths. The integrated microcontroller allows for flexible OEM differentiation through custom firmware rather than hard-coded logic. Verify that the application environment remains within the specified 0°C to +70°C operating temperature range.
