Microchip LAN9513I-JZX: A High-Performance USB 2.0 Hub and 10/100 Ethernet Controller

In the realm of embedded systems and connected devices, the integration of multiple functionalities into a single, compact component is paramount for reducing design complexity, saving board space, and lowering overall system cost. The Microchip LAN9513I-JZX stands out as a premier solution, expertly combining a high-performance USB 2.0 hub with an integrated 10/100 Ethernet controller on a single chip.

This highly integrated IC is specifically engineered to provide a robust network connection and expanded USB capability for a wide array of applications. It is particularly prevalent in set-top boxes, network-attached storage (NAS) devices, printers, and other embedded systems where a single USB port needs to be expanded while simultaneously adding reliable Ethernet connectivity.

The device features a 4-port USB 2.0 hub, with one upstream port and four downstream ports, supporting both high-speed (480 Mbps) and full-speed (12 Mbps) operations. This allows multiple USB peripherals—such as keyboards, mice, storage drives, and cameras—to be connected simultaneously through a single host connection. The integration of a dedicated Ethernet controller eliminates the need for a separate network interface card (NIC). It incorporates a full IEEE 802.3-compliant 10/100 Ethernet PHY and MAC, supporting both HP Auto-MDIX for automatic cable detection and advanced power management features.

A key advantage of the LAN9513I-JZX is its single-chip design, which significantly simplifies the bill of materials (BOM) and reduces the PCB footprint. This integration enhances system reliability by minimizing the number of discrete components required. Furthermore, the controller is designed for low power consumption, making it an ideal choice for power-sensitive applications. Its industrial temperature rating (-40°C to +85°C) ensures stable and dependable operation even in harsh environmental conditions.

The chip communicates with the host system via a standard PCIe or USB interface for the network controller, offering flexibility for different system architectures. Its built-in firmware is stored in an on-chip ROM, requiring no external memory for basic operations, which further contributes to its simplicity and cost-effectiveness.

ICGOODFIND: The Microchip LAN9513I-JZX is a superior, highly integrated solution that masterfully combines a 4-port USB 2.0 hub with a fully-featured 10/100 Ethernet controller. Its robust integration, low power consumption, and industrial-grade reliability make it an exceptional choice for developers aiming to enhance connectivity in space-constrained and cost-sensitive embedded designs.
