LAN9513I-JZX

Controllers Overview

The LAN9513I-JZX is a high-performance Hi-Speed USB 2.0 hub integrated with a 10/100 Ethernet controller, manufactured by Microchip Technology. It features three downstream and one upstream USB port, each equipped with an integrated PHY. The device includes an integrated 10/100 Ethernet MAC and PHY supporting full- and half-duplex modes. It operates within the industrial temperature range of -40°C to +85°C and utilizes a 64-pin QFN package.

Controllers Feature Summary

• Integrates a USB 2.0 hub with three downstream ports and one upstream port, including dedicated transaction translators for mixed-speed peripherals.
• Combines a 10/100 Ethernet MAC and PHY with support for auto-negotiation, HP Auto-MDIX, and Wake-on-LAN capabilities.
• Includes an EEPROM controller for automatic loading of static configuration data, USB descriptors, and MAC addresses upon reset.
• Provides programmable features such as PortMap, PortSwap, and PHYBoost to optimize signal integrity and PCB layout flexibility.

Controllers Applications

• Desktop PCs
• Notebook PCs
• Docking Stations

Controllers Procurement Notes

Verify the specific suffix 'JZX' against the manufacturer's current documentation to confirm packaging details and environmental compliance status. Ensure the industrial temperature grade (-40°C to +85°C) matches the application requirements. Confirm that the 64-pin QFN package dimensions align with the target PCB footprint design.

Controllers Selection Notes

Select this component when a combined USB hub and Ethernet solution is required to minimize bill of materials cost. It is suitable for designs needing integrated PHYs for both USB and Ethernet interfaces. Consider the available GPIOs and LED indicators if peripheral control or status indication is needed without additional logic components.

Controllers Part Context

The LAN9513I-JZX belongs to the LAN9513 family of USB/Ethernet controllers. The 'I' designation indicates the industrial temperature range variant, while 'JZX' typically refers to the specific tape-and-reel packaging format. This part serves as a connectivity bridge in systems requiring multiple USB devices and network access from a single host connection.

Controllers FAQ

What is the function of the VBUS_DET pin?

The VBUS_DET pin detects the state of the upstream bus power. For bus-powered hubs, it must be tied to VDD33IO. For self-powered hubs permanently attached to a host, it should also be pulled to VDD33IO to signal connection events.

How does the device handle over-current conditions on downstream ports?

The PRTCTL pins serve as both power control outputs and over-current sense inputs. When used with an external power switch or poly fuse, an over-current condition pulls the signal low, which the device recognizes via its Schmitt trigger input to indicate a fault.

Can the LAN9513I-JZX operate without an external EEPROM?

Yes, but if no properly configured EEPROM is detected, the Host LAN Driver is responsible for setting the IEEE addresses and USB descriptors manually after reset.
