# 8 bit microcontroller and w5500

## Question

Asked by k13bc on 2014-04-16 in Ethernet Chips.

Hi there,

I want my system as internet client so i would like to know if W5500 chip is full supported from 8bit microcontrollers like avr ATmega or it needs arm 32bit? Which ethernet library and SPI driver are ok to be used with winavr or codevision (language C/C++)? Or the common solution from arduino and w5100 is the 8bit way?

Thanks
