Power & Reset Input
The Zynq Ult MPSoC 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 Zynq Ult MPSoC SOM supports VCC_RTC coin cell power input from Board to Board Connector2 and
connected to
PMIC
’s
VBBAT pin for real time clock backup voltage. Also it supports warm reset input from Board to
Board Connector2 and connected to PS_SRST_B pin of MPSoC.
For more details on Power pins on Board to Board Connector2, refer the below table.
