LAN9512-JZX-TR

Controllers Overview

The LAN9512-JZX-TR is a high-performance Hi-Speed USB 2.0 hub integrated with a 10/100 Ethernet controller, manufactured by Microchip Technology. It features one upstream and two downstream USB ports with integrated PHYs, alongside an IEEE 802.3 compliant MAC and PHY. The device supports Full-Speed (12 Mbps) and High-Speed (480 Mbps) data rates, operates on a single 25 MHz crystal, and includes an internal 1.8V core regulator with external 3.3V I/O supply. Packaged in a lead-free RoHS-compliant 64-pin QFN, it targets desktop PCs, notebooks, printers, game consoles, embedded systems, and docking stations.

Controllers Feature Summary

• Integrates a fully compliant USB 2.0 hub with three dedicated Transaction Translators for mixed-speed peripheral support.
• Combines a 10/100 Ethernet MAC and PHY supporting auto-negotiation, HP Auto-MDIX, and full/half-duplex operation.
• Provides advanced power management capabilities including multiple suspend modes and individual port power control.
• Includes an EEPROM controller for automatic loading of USB descriptors and MAC addresses upon reset.

Controllers Applications

• Desktop PC connectivity expansion
• Notebook PC docking solutions
• Printer network integration
• Game console peripheral hubs
• Embedded system USB/Ethernet bridges

Controllers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and environmental compliance. Ensure the component matches the required temperature range for the target application. Confirm that the datasheet revision aligns with current manufacturing specifications before finalizing procurement orders.

Controllers Selection Notes

Select this component when a combined USB hub and Ethernet solution is required to minimize bill of materials. Consider the integrated PHYs and single-crystal requirement for simplified PCB layout. Evaluate the available GPIOs and LED indicators for status monitoring needs. Verify compatibility with the intended host operating system drivers.

Controllers Part Context

This part belongs to the LAN9512 family, which serves as a cost-effective connectivity bridge. It is designed to replace discrete hub and Ethernet controller combinations. The JZX suffix typically denotes the specific package variant within the broader product line.

Controllers Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify pinout and electrical characteristics match if replacing with similar devices from other manufacturers.
