MCHPLAN9250I/PT
Overview
The LAN9250I/PT is a high-performance 10/100 Industrial Ethernet controller featuring an integrated PHY and MAC designed for high-reliability embedded systems. It supports the IEEE 1588v2 standard for hardware-based precision timing and is compliant with Energy Efficient Ethernet (802.3az) to reduce power consumption during periods of low data activity. This industrial-grade IC operates across a wide temperature range and offers multiple power-down modes to optimize efficiency in power-constrained designs.
Why Choose This Part
This controller simplifies PCB design with an integrated 1.2V regulator for single-supply 3.3V operation and variable I/O voltages from 1.8V to 3.3V. The inclusion of hardware-based IEEE 1588v2 time stamping enables sub-microsecond synchronization without taxing the host processor's resources.
Applications
Getting Started
Engineers can evaluate this part using the EVB-LAN9250 evaluation board, which provides a standard RJ45 connector and access to host interfaces via SPI or memory bus. Development is supported by Microchip's comprehensive software driver library, compatible with various RTOS and bare-metal environments.
