STM32N6 – Contradictory information regarding SMPS bypass capabilities

Good morning,

I have found contradictory information regarding the bypass requirements of the SMPS integrated in the microcontroller.

In particular, the datasheet, section 3.4.4, states that 60 µF are required, implemented as 4 × 15 µF.

However, this information appears to contradict what is stated in AN5967 (Table 4) and in the Nucleo reference design (MB1940-N657x0Q-C02).

My question is:

Are the 20 µF stated in AN5967 and used in the Nucleo board sufficient to ensure proper operation of the SMPS?

Best regards,
