108 / 235 page ![]() System reset ST10F276E 108/235 Doc ID 12303 Rev 3 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 Chapter 23: Electrical characteristics). In next figures 24 and 25 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. |
