ST STM32U585 Series - Page 16

Caution: STM32U575/585 packages with and without SMPS are not compatible, in almost all power supply pins of
the above table.
Example: VDDIO2 is the pin number 130 on SMPS package. Pin 130 on the package without SMPS is mapped
to a VSS pin. It means the system is short-circuited when a legacy package is mounted on an SMPS socket.
