¹ Cyclone V SoC Qseven SOM is designed to work with VCC input power rail from Qseven Edge connector. Optionally
we can use On-SOM Power In connector to feed VCC which can be used only for standalone power up.
² Cyclone V SoC Qseven SOM doesn’t support VCC_5V_SB standby voltage input from Qseven Edge Connector.
³
Cyclone V SoC Qseven SOM uses this voltage as backup power source to RTC controller when VCC is off.
3.1.2
Power Input Sequencing
Cyclone V SoC Qseven SOM Power Input sequence requirement is explained below.
Power up Sequence:
VCC_RTC must come up at the same time or before VCC comes up.
PWGIN signal from Qseven Edge must be active at the same time or after VCC comes up.
Power down Sequence:
PWGIN signal from Qseven Edge must be inactive at the same time or before VCC goes down.
VCC must go down at the same time or before VCC_RTC goes down.
