Configuring VCCIO-Voltage as example with mounted 4x5 SoM TE0720
The Zynq-module's power supply is fixed to 5V5.0V!
Additionally, the VCCIO33 and VCCIO34 supply voltages of the Zynq FPGA (on bank 33 and bank 34, respectively) can be selected either to be 3.3V (J17:1-2, 3) or 2.5V (J17: 1, 2-3). The latter is the default setting (i.e., VCCIO33=VCCIO34=2.5V). By removing jumper J17 and setting jumper J16 VCCIO33 and VCCIO34 will be set to the adjustable voltage FMC_VADJ.

Additionally, the TE0701 carrier board is equipped with a second mini USB port (J7; see (8) in Figure 1) that is connected to a "USB to multi-purpose UART/FIFO IC" from FTDI (FT2232HQ) and provides a USB-to-JTAG interface between a host PC and the TE0701 carrier board and the Zynq-module, respectively. Because it acts as a USB function device, no power switch is required (and only a ESD protection must be provided) in this case.

-configuration via jumpers
There are two base board supply-voltages VIOTA, VIOTB and for VIOTA and VIOTB connected to the 4x5 SoM's PL IO-banks. The supply-voltages have following pin assignments on B2B-connectors:
base-board supply-voltages | base-board B2B connector-pins | standard assignment of PL IO-bank supply-voltages on TE 4x5 module's B2B connectors | base-board voltages and signals connected with |
|---|---|---|---|
| VIOTA | JB2-2, JB2-4, JB2-6 | VCCIOB (JM2-1, JM2-3) / VCCIOC (JM2-5) | HDMI_SCL, HDMI_SDA, HDMI_INT, J5 VCCIO |
| VIOTB | JB1-10, JB1-12, JB2-8, JB2-10 | VCCIOA (JM1-9, JM1-11) / VCCIOD (JM2-7, JM2-9) | VCCIO1 (Systm-Controller-CPLD pin 55, 73) |

Note: The corresponding PL IO-voltage supply voltages of the 4x5 SoM to the selectable base-board voltages VIOTA and VIOTB are depending on the mounted 4x5 SoM and varying in order of the used model. Refer to SoM's schematic to get information about the specific pin assignment on module's B2B-connectors regarding PL IO-bank supply voltages and to the 4x5 Module integration Guide for VCCIO voltage options. |
Following table gives the conjunction between the base-board supply-voltages VIOTA, VIOTB and the PL IO-bank's voltages of 4x5 SoMs:
