7.4 Supply
Voltage
The C6713CPU must be supplied with a voltage of n3.3 V. The integrated switching
voltage regulators generate all necessary on-board voltages.
CAUTION:
The C6713CPU is not protected against reversed voltage. Please be careful when connecting
power supply to the board. Applying reversed voltage will damage the board.
CAUTION:
The power up voltage ramp time must be at least 0.6 ms. The ramp time is measured from 10% to
90% of the full nominal voltage swing. Direct plugging a 3.3V power cable into a working 3.3V
power supply may damage the board.
