System Monitor
The SYSMON monitors the physical environment using on-chip temperature and supply
sensors, up to 17 external analog inputs, and an integrated analog-to-digital converter
(ADC). The SYSMON is powered using the on-chip reference (VREF) shown in
More information about the system monitor is available in the UltraScale Architecture

I2C Bus Management
The I2C bus is routed through U22, an 8-channel I2C-bus multiplexer (NXP Semiconductor
TCA9548). The I2C IDcode for the PCA9548 device is 0x75. The multiplexer provides
I2C/PMBus communication between the bus master (system controller or FPGA) and six
sub-systems:
•
Onboard regulators and power monitoring
•
SuperClock-2 module
•
System controller EEPROM
•
FMC1 connector
•
FMC2 connector
•
FMC3 connector
