7.4 Supply Voltage
The C6713CPU must be supplied with a voltage of nominal +3.3 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.
Board type minimum allowed supply voltage maximum allowed supply voltage

7.5 Power Consumption
The typical power consumption is shown in the following table. Please note that the power
consumption strongly depends on I/O pin usage and the FPGA design.
