Electrical parameters

Figure 26. Recommended NRST pin configuration

The reset network shown in Figure 26 protects the device against parasitic resets. The user

must ensure that the level on the NRST pin can go below the VIL max. level specified in

Table 33

. Otherwise the reset is not taken into account internally.

For power consumption sensitive applications, the capacity of the external reset capacitor

can be reduced to limit the charge/discharge current. If the NRST signal is used to reset the

external circuitry, the user must pay attention to the charge/discharge time of the external

capacitor to meet the reset timing conditions of the external devices. The minimum

recommended capacity is 10 nF.
