This power was measured under the following conditions:
The following table shows the current consumption for the P3V3_AUX rail.
Current consumption on this rail does not vary so much with load conditions.
A.2.3 3.3 V Auxiliary Supply
The following functions are powered from the 3.3 V Auxiliary supply
(VPX P3V3_AUX line):
• SmartFusion2 FPGA/BMM and System Management Bus
• Power supply sequencing/monitoring
• BIT Fail LED
• Real Time Clock (this can also be powered from the VPX VBAT supply)
• PCH resume functions
NOTE
The SBC347A requires the Auxiliary supply to be present, otherwise it will not start up.
