sufficient: anyway, 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 anyway recommended also to

avoid risks of damage in case of temporary short between

V18 and ground: the internal 1.8V drivers are sized to drive

currents of several tens of Ampere, so the current shall be

limited by the external hardware. The limit of current is

imposed by power dissipation considerations (Refer to

Electrical Characteristics Section).

In next Figures

17 and 18 Asynchronous Power-on timing diagrams are reported,

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

extension introduced by the embedded FLASH module when selected.

Note:

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

unpredictable states, risking also permanent damages.
