The board provides an Arduino® Shield interface. This interface is connected to XCSU35P HDIO bank 68. The Arduino Shield interface provides 14 digital I/O, 6 analog I/O, 2 power pins, and 2 ground pins.
All XCSU35P I/Os connected to the Arduino Shield interface support single-ended line rate of 250 Mb/s.
The Arduino Shield power pins are supplied by 3.3 V and 5 V. Reverse current blocking eFuses are provided for overcurrent and reverse current protection. A maximum current of 0.5 A may be drawn from the 3.3 V rail and 1 A from the 5 V rail.
Note: The board does not
support Arduino Shield boards that supply power. The Arduino Shield VIN pin is
unconnected.
Important: The XCSU35P FPGA I/Os are not 5V
tolerant! Arduino Shields that use 5V I/O cannot be used with the SCU35 board. The
maximum voltage that can be applied to the XCSU35P FPGA HD I/Os is Vcco + 0.550V.
Additionally, the FPGA bank I/O voltage must match the requirements for the I/O
standards that have been assigned to the I/O bank.
