DESCRIPTION

Description

OVERVIEW

Product Overview

The LAN9514I-JZX is a combined USB hub and Ethernet controller from Microchip used to expand USB ports and provide Ethernet connectivity in embedded systems. It integrates a multi-port USB hub and an Ethernet controller, reducing the peripheral burden on the host processor and saving board space. The device suits embedded equipment that needs both USB expansion and wired network access, connecting to the host controller through standard interfaces. The I suffix generally indicates an industrial temperature grade, and JZX corresponds to a QFN package. Refer to the original datasheet for exact port count, speed, interfaces and supply requirements.

APPLICATIONS

Applications

  • Used on embedded mainboards to expand multiple USB peripheral interfaces.
  • Used in industrial equipment to provide wired Ethernet communication.
  • Used in network terminal devices for integrated USB and Ethernet connectivity.
  • Used in set-top boxes or multimedia devices to expand connectivity.
FEATURES AND BENEFITS

Features and Benefits

  • Integrates USB hub and Ethernet controller to reduce external components.
  • Supports multi-port USB expansion for connecting peripherals.
  • Integrated wired Ethernet enables embedded device networking.
  • QFN package suits space-constrained circuit boards.
  • Industrial temperature suffix accommodates a wider ambient temperature range.
ADDITIONAL DETAILS

Additional Details

When purchasing, confirm the suffix and package correspond to QFN, and verify the temperature grade and port configuration. This is an integrated controller with relatively complex interface and supply requirements; request the original datasheet from the supplier before selection and circuit design, and avoid mixing with other versions.

Verify product details against the manufacturer datasheet before purchase.
