MICROCHIP LAN9255-V/ZMX020

The LAN9255 is a System-In-Package (SIP) design that combines the 2/3-port EtherCAT device controller with dual integrated Ethernet PHYs and the ARM Cortex-M4F MCU into a single 128-pin TQFP package. The LAN9255 is available in commercial [0°C to +70°C], industrial (-40°C to +85°C), and extended industrial (-40°C to +105°C) temperature ranges.
