Hi HK,

The SPI and I2C can go on any open GPIO pins. You chose what is best for your design. The only thing to be careful about is making sure that your choice of SPI or I2C peripherals do not conflict as I believe they share peripheral resources.

Thanks, Also Can I use regulated 1.8volt to power the circuit ?

Well, the processor will run down to 1.7, so I don't see why not.
