VDDNRSTIN Pin
NRSTIN Pin Input Driver is CMOS. A permanent pull-up is present which is the same as
Subject to general operating conditions for VDD and TA unless otherwise specified.
Notes:
1.
Data based on characterization results, not tested in production.
2.
Hysteresis voltage between Schmitt trigger switching levels.
3.
Data guaranteed by design, not tested in production.
Figure 13. Recommended NRSTIN pin
protection.1)
Notes:
1.
The RPU pull-up equivalent resistor is based on a resistive transistor.
2.
The reset network protects the device against parasitic resets.
3.
The user must ensure that the level on the NRSTIN pin can go below the VIL(NRSTIN) max. level specified in
Table 23. Otherwise the reset will not be taken into account internally.
