System reset

the on-chip voltage regulator functionality 10nF is sufficient:

In any case, a maximum of 100nF on V18 pin should not

generate problems of over-current (higher value is allowed if

current is limited by the external hardware). External current

limitation is nevertheless also recommended to avoid risks of

damage in case of a temporary short between V18 and

ground: The internal 1.8V drivers are sized to drive currents

of several tens of Amps, so the current must be limited by the

external hardware.

The limit of current is imposed by power dissipation

considerations (refer to Section 24: Electrical

characteristics).

In the next Figures 17 and 18 Asynchronous Power-on timing diagrams are shown,

respectively with boot from internal or external memory, highlighting the reset phase

extension introduced by the embedded Flash module when selected.

Caution:

Never power the device without keeping the RSTIN pin grounded: The device could enter

into unpredictable states, risking also permanent damage.
