The reset network shown in the following figure protects the device against parasitic resets.
The user must ensure that the level on the NRST pin can go below V
I/O static characteristics
For power consumption sensitive applications, the external reset capacitor value can be
reduced to limit the charge/discharge current. If NRST signal is used to reset external circuitry,
attention must be taken to the charge/discharge time of the external capacitor to fulfill the
external devices reset timing conditions. Minimum recommended capacity is 100 nF.

Unless otherwise specified, the parameters given in the following table are derived from tests
performed under ambient temperature, f
