NRST pin characteristics
The NRST pin input driver uses CMOS technology. It is connected to a permanent pull-up
resistor, RPU (see Table 33).
Unless otherwise specified, the parameters given in Table 36 are derived from tests
performed under ambient temperature and VDD supply voltage conditions summarized in
Figure 20.
Recommended NRST pin
protection
1.
The reset network protects the device against parasitic resets.
2.
The user must ensure that the level on the NRST pin can go below the VIL(NRST) max level specified in
Table 36. Otherwise the reset will not be taken into account by the device.

2.
The pull-up is designed with a true resistance in series with a switchable PMOS. This PMOS contribution
to the series resistance must be minimum
