RTC Controller
Cyclone V SoC Qseven SOM supports On-SOM external RTC Controller “BQ32000DR”. This device is connected to the
HPS Block of the Cyclone V SoC through I2C0 Interface and operating under 3.3V Voltage level. IRQ output of this
device is connected to HPS_GPI9. In SOM power off condition, this device will take power from Qseven Edge
VCC_RTC coin cell power input (Pin 193).
