In the power schemes in the STR751FR0 data sheet it is written that there are four power schemes ,single 3.3V or 3.3V + 1.8 V or single 5 V or 5V+1.8V.

But in the table of the same data sheet HEREBY ATTACHED it is written only 3.3V supply.

My question is:

Can I power the STR751FR0 with a single supply of 5 Volts.

Few pages later there is a caution: ''When powered by 5.0V, the USB peripheral cannot operate.''

So 5.0V supply for STR751 and STR750 is with restricted use only...

Yes there are four power schemes for the STR75x devices. With the wide range of STR75x part number, you can choose the suitable part number for your application. The STR751 is the one integrating the USB and recommend the 3.3V power supply since with 5.0V the USB is not available. if you don't use the USB in your application, you can choose either the STR755 or STR752. 😉
