RSTIN pin
The RSTIN pin input driver is CMOS. A permanent pull-up is present which is the same as
Subject to general operating conditions for V33 and TA unless otherwise specified.
Notes:
1.
Data based on characterization results, not tested in production.
2) Data guaranteed by design, not tested in production.

Recommended RSTIN pin
protection.1)
Notes:
1.
The RPU pull-up equivalent resistor is based on a resistive transistor (corresponding IPU current
characteristics described in Figure 18).
2.
The reset network protects the device against parasitic resets.
3.
The user must ensure that the level on the RSTIN pin can go below the VIL(RSTINn) max. level specified in
Table 31. Otherwise the reset will not be taken into account internally.
