FPGA Mode Configuration
The Kintex Ult SOM provides mode pins for selection of configuration device. The SOM supports 4-bit QSPI Flash and JTAG
for the configuration of FPGA.
By default, mode bit is configured to “001” for
QSPI Flash as configuration device.
Below table provides the Mode bit status for available configuration devices of SOM.

FPGA System Monitor/ADC
The Kintex Ult FPGA contain one System Monitor block (SYSMONE4). It is used to enhance the overall safety, security and
reliability of the system by monitoring the physical environment via on-chip power supply and temperature sensors.
The SYSMON uses 10-bit 200kSPS ADC to digitize the sensor/ADC inputs. It monitors the die temperature of the FPGA and several
internal supply nodes. The SYSMON can also monitor up to 17 external analog channels which includes 16 auxiliary analog inputs
and one VP_VN dedicated input. The external auxiliary inputs can be routed through any IO Bank. The ADC voltage reference is
selectable between an internal reference and the external pins VREFP and VREFN. In Kintex Ult FPGA SOM, 1.25V external
voltage reference is supported.
