Warning:

It is recommended to provide the external hardware with a

current limitation circuitry. This is necessary to avoid

permanent damage to the device during the power-on

transient, when the capacitance on V18 pin is charged. For

the on-chip voltage regulator functionality, 10 nF is sufficient.

A maximum of 100 nF on the V18 pin should not generate

problems of overcurrent (a higher value is allowed if the

current is limited by the external hardware). External current

limitation is also recommended to avoid risks of damage in

case of temporary shorts between V18 and ground. The

internal 1.8 V drivers are sized to drive currents of several

tens of ampere, so, the current must be limited by the

external hardware. The current limit is imposed by power

dissipation considerations (refer to Section 24: Electrical

characteristics).

Figure 75 and Figure 76 show the asynchronous power-on timing diagrams with boot from

internal or external memory respectively. The reset phase extension that is introduced by

the embedded Flash module, is highlighted.

Note:

Never power the device without keeping the RSTIN pin grounded as the device could enter

unpredictable states which could permanently damage it.
