Hi,

 

we have chosen ADE7758 for energy meter application and need to interface micro controller through SPI. But ADE7758 VCC is 5V level but our Micro controller VCC 3.3V level, How to interface ADE to Micro controller through SPI communication?

Is require 5 to 3.3V level shift IC or can i connect directly to our controller?

If i connect directly ADE-SPI pins to micro controller, controller will damage? Please suggest the same

 

Thanks & Regards,

Panneerrajan
