LAN9512-JZX

The LAN9512-JZX is an USB 2.0 hub and 10/100 Ethernet Controller. It is targeted as a high performance, low cost USB/Ethernet and USB/USB connectivity solution. This is specifically designed to provide system architects with a low-cost, power-efficient, small-footprint USB to Ethernet and multi-port USB connectivity solution. The LAN9512 contain a high speed USB 2.0 hub with two fully-integrated downstream USB 2.0 PHYs, an integrated upstream USB 2.0 PHY, a 10/100 Ethernet MAC/PHY controller and an EEPROM controller. It offers Microchip's highest level of USB 2.0 and 10/100 Ethernet compliance and interoperability. Additionally, this device simplifies system design by leveraging the existing USB stack and reducing the PCB footprint by up to 65% compared to discrete competitive solutions.
