About the information of the data sheet I think in pin number 6 It is neccessary to connect a voltage of 3,3 volts, and in the pins 47 I don´t know, in my application the Vdd will be 5 volts, so I would like to know what voltage I have to connect in these pins ( 6 and 47 ) , and how much is the normal current of these pins.

The 5V version (uPSD3312D-40T) requires both a 5V and 3.3V supply.

Referring to the data sheet on page 12, pins 6 and 47 are labeled ''3.3V-VCC'' and should be connected to VCC. They supply the power to the MCU Module. The PSD module in the device operates on 5V which is supplied from pins 8 and 33 (''VDD''). You can also refer Table 3 which also shows what was metioned above. The data sheet does include current consumption numbers for the PSD module; however, the MCU module is still ''TBD'' and those numbers should be available within a few months.
