What voltages does the DS80C400 require?

The DS80C400 requires both a 1.8V supply and a 3.3V supply. The I/O pads of the device are powered by the 3.3V supply, allowing the device to interface to 3.3V logic. The 5V tolerant I/O of the microprocessor can be interfaced to 5V peripherals. The order of sequencing of VCC1 and VCC3 is not important. The DSTINIm400 uses the MAX1792 low-dropout linear regulator to generate the 1.8V from the 3.3V supply.
