100 nF filtering capacitor on each package pin.

A tolerance of +/- 20% is acceptable on decoupling capacitors.

Note:

Refer to Getting started with STM32H7A3/7B3 and STM32H7B0 hardware development(AN5307) for more

details.

Caution:

Each power supply pair (VDD/VSS, VDDA/VSSA ...) must be decoupled with filtering ceramic capacitors as shown

above. These capacitors must be placed as close as possible to, or below, the appropriate pins on the underside

of the PCB to ensure good operation of the device. It is not recommended to remove filtering capacitors to

reduce PCB size or cost. This might cause incorrect operation of the device.

Absolute maximum ratings

Stresses above the absolute maximum ratings listed in Table 17. Voltage characteristics, Table 18. Current

characteristics, and Table 19. Thermal characteristics may cause permanent damage to the device. These are

stress ratings only and the functional operation of the device at these conditions is not implied. Exposure to

maximum rating conditions for extended periods may affect device reliability. Device mission profile (application

conditions) is compliant with JEDEC JESD47 Qualification Standard, extended mission profiles are available on

demand.

Table 17. Voltage characteristics

All main power (VDD, VDDA, VDD33USB, VDDMMC, VDDSMPS, VBAT) and ground (VSS, VSSA) pins must always be connected to the

external power supply, in the permitted range.
