8.5 DFSDM STMP2 and PT100 monitoring
8.5.1 Description
Two STMPS2 ICs are connected to STM32H7B3LIH6QU DFSDM1_2 interface:
• U36 is transmitting analog data from a power metering jumper (JP1) to DFDSM_DATIN1.
• U37 is transmitting temperature analog data from a PTS (R200) to DFDSM_DATIN5.
8.5.2 Operating voltage
STM32H7B3LIH6QU DFSDM STMPS2 and PT100 monitoring interfaces can only be at 3.3 V on this board. The
power supply (VCC) of both STPMS2L-PUR (U36 and U37) is “3V3_SW”. Take care to control this power supply
or use one of the hardware configurations to force it “always ON” (Refer to Section 8.5.2 )
8.5.3 Limitations and hardware configuration
Limitations: DFSDM Audio and USB HS
Hardware modifications:
• Fit R201, R202, R205, R208, and R33.
• Remove the MB1299 DFSDM audio module.
