AM1707: power consumption on +1.8V power rail
AM1707: What is the power consumption of +1.8V rail in three case below:
You should be able to deduce this by going through the power consumption summary wiki and the power estimation spreadsheet for AM17xx
If you do not have USB in your design, you will not need a 1.8V supply as except for USBs, all other IOs are 3.3V.
Don't forget to verify answers to your forum questions by using the green "Verify Answer" button.
In our design we use 1 USB0 (USB2.0 OTG), but in power spreadsheet I don't see the power consumption on +1.8V rail.
Picture attachment is power spreadsheet that I calculated, please have a look.
For the USB2.0 or USB1.1 row, on column L there is a drop down menu to change from No Activity to PHY ENABLE or HS/FS Transmit/Receive. Configure those cells to assess the power on the 1.8V rail for the various USB modes.
