Hi， REN Expert：
The IO voltage of most SOC & module is only 1.8V level,[Over 60%], It means adding a lots of Level Shifts IC on electrical connection。
Does the U2Axx support 1.8V IO voltage？
I found the IO voltage is 3.0~5.5V on the manual.
You can find solution? if yes can you provide me solution. Fortiva Credit Card
