Power & Reset Input
The Kintex Ult FPGA SOM works with 5V power input (VCC) from Board-to-Board Connector2 and generates all other
required powers internally On-SOM itself. SOM power can be enabled/disabled from the carrier board through SOM Power enable
pin (pin232) in Board-to-Board Connector1. Also, in Board-to-Board Connector2, Ground pins are distributed throughout the
connector for better performance.
The Kintex Ult FPGA SOM supports VRTC_3V0 coin cell power input from Board-to-Board Connector2 and connected to
PMIC’s
VBBAT pin for real time clock backup voltage.
For more details on Power pins on Board-to-Board Connector2, refer the below table.
