MCHPLAN9500A-ABZJ
Overview
The LAN9500A-ABZJ is a high-performance, small-form-factor USB 2.0 to 10/100 Ethernet controller designed for embedded systems requiring high-speed network connectivity. It integrates a 10/100 Ethernet MAC, a PHY with HP Auto-MDIX support, and a USB 2.0 device controller into a single 56-pin QFN package. The device is optimized for low power consumption, featuring multiple suspend modes and an integrated 1.2V regulator to simplify power rail management.
Why Choose This Part
This controller offers a highly integrated solution that reduces BOM count by including the PHY and oscillator circuitry on-chip. It supports advanced features like NetDetach for reduced power consumption when the Ethernet cable is unplugged and reaches throughput speeds up to 69mA in full-duplex operation. The 11 GPIO pins provide additional flexibility for system control without requiring external expanders.
Applications
Key Specifications
Getting Started
Designers can evaluate this part using the EVB-LAN9500A-MII evaluation board. Software development is supported through Microchip's comprehensive driver suite for Windows, Linux, and macOS, while the JTAG interface allows for advanced debugging. Ensure the 56-QFN exposed pad is properly soldered to a ground plane for thermal dissipation as specified in the 8x8mm package guidelines.
