Hi Everyone,
I'm designing a UART 2 Ethernet convert PCB module. I've gone through a below link design
https://www.nxp.com/docs/en/application-note/AN3906.pdf
But I've 1 query whether if I use the MCF51CN ic, then does it have firmware inside to pass the data from uart to ethernet connector or vice versa, or I've upload a firmware?
