Operation Case

One Device SPI Mode, Bidirectional – 4 Wire, 3V3 Operation

device.

4.1.1

3V3 Operation

Supply 5V pin and 3V3 with 3.3V.

As an alternative, the user can assemble R1 with a 0 ohm bridge to short the 5V and VDD3V pin. In

this case, only one of the supply pins need to be supplied with 3.3 V.

Digital output operates at 3.3V level.
