Hi, I would like to use with Ethernet. I need to build minimal board. In datasheet I found: ''Ethernet MAC interface with dedicated DMA and IEEE 1588 support''. Is possible to connect RJ45 connector directly to MCU or I must add any other electronics parts?
Is good choice to use Ethernet in MCU or is better to buyhttps://www.olimex.com/Products/Modules/Ethernet/ENC28J60-H/
? How compilicated is minimal circuit with STM32 and Ethernet? Now I am using 8bit Arduino with ENC28J60 and board is very simple (http://www.instructables.com/id/A-credit-card-sized-Ethernet-Arduino-compatable-co/?ALLSTEPS
). Thank you for help!- Mark as New

How good are your design/implementation skills?
You will need a PHY and RJ45 with suitable magnetics. See Pg 18http://www.st.com/st-web-ui/static/active/en/resource/technical/document/user_manual/CD00246066.pdf
If you want a lower cost implementation that supports 100 Mbps rather than just 10 Mbps, you'd go with the MAC integrated into the STM32, wouldn't you?Up vote any posts that you find helpful, it shows what's working..

My design skills are not very good :(
I am trying to build temperature watchdog with internet control. I need 1 input for 1-Wire temperature sensor, 2 outputs for relay and Ethernet interface. I do not need hight speed Ethernet, 10Mbps is sufficient. What MCU you recommend to me? I found and it looks good for me. What is your opinion? So I need only MCU, 25MHz crystal, RJ45 to MCU separator (for examplehttp://cz.farnell.com/pulse/h1012nl/module-transformer-ethernet/dp/2113972
) and +3.3V power supply. Is it all?- Mark as New
