Functional overview

3.17.2

Internal reset OFF

This feature is available only on packages featuring the PDR_ON pin. The internal power-on

reset (POR) / power-down reset (PDR) circuitry is disabled by setting the PDR_ON pin to

low.

An external power supply supervisor should monitor VDD and should set the device in reset

mode when VDD is below 1.7 V. NRST should be connected to this external power supply

supervisor. Refer to Figure 7: Power supply supervisor interconnection with internal reset

OFF.

A comprehensive set of power-saving mode allows to design low-power applications.

When the internal reset is OFF, the following integrated features are no longer supported:

•

The integrated power-on reset (POR) / power-down reset (PDR) circuitry is disabled.

•

The brownout reset (BOR) circuitry must be disabled.

•

The embedded programmable voltage detector (PVD) is disabled.

•

VBAT functionality is no more available and VBAT pin should be connected to VDD.

3.18

Voltage regulator

The regulator has three operating modes:

–

Main regulator mode (MR)

–

Low power regulator (LPR)

–

Power-down
