# Accessing multiple WizNet Chips with same microcontroller

## Question

Asked by mge on 2022-01-24 in Ethernet Chips.

Hi, i’d like to use three WIZNet W6100 with single Mircocontroller via SPI Interface. Is it possible to acces them with io Library? Do i need three instances of iolibrary? Should i use three seperated SPI Interfaces? Hope you can give me some Recommandations :-). Cheers
