| Selecting Mictocontroller for Ethernet Application |

Hello everyone, I am new to Ethernet. I want to select a micro-controller for 10base-T/100base-TX, MII/RMII Ethernet application. 1. Is there any guideline available for selecting a micro-controller? 2. Which parameters should I focus on to compare the micro-controllers from several manufacturers (ST, TI etc.)? 3. Does anyone have a excel sheet comparison? Thank you |

Only ethernet, or also internet? For the second, get an small linux SBC or SOC. Much much easier software and future maintainability. |

the cheapest would be an arduino and a wiznet shield on it (or sometimes called etherduino) I also like the pic 18f6xj6x family that connect directly to ethernet. but the dev boards and softwares for it a more expensive. you should also tell us about the application, as it may require some fast calculations ? or is it "just" about IOT and switching things remotely ? |

Ethernet is pretty useless without the rest of the TCP/IP stack so when shopping around, look to see if the vendor has the entire protocol stack- free, of course! There are a lot of ports of lwIP (Lightweight IP) and it's a pretty decent stack. Actually, the Raspberry Pi is probably the way to go. It has the entire Linux networking stack. Maybe after the project is debugged on the Pi it can be ported to something cheaper but the initial development time will be a lot shorter when using a Pi. |

I find the raspberry pretty overkill in many IOT applications. and developping on a Pi is completely different than other platforms (as you said you have to adapt to the tcp stack) with arduino+wiznet, you have a free tcp stack inside the woznet. also you can use an esp32 with a lan8720 board. there are examples around. more power than an arduino. |
