Can ST8500 MCU support communication through DC lines? The Voltage of the DC lines will be around 5-20V.

How about checking the datasheet: https://www.st.com/resource/en/datasheet/st8500.pdf ?

Ya I have checked but it lacks clarity.They haven't directly mentioned it supports communication through DC line.

DC to 500 KHz​

Probably would have lead​ with something clearer in front page bullets.

Thank you. I did see that. DC with what voltage???

Would suggest you talk with an FAE supporting the Power Line Comms products.

I'd presume it would connect via a DC blocking capacitor. The ADC has a 1.8V p-p range
