Typical ratings are not guaranteed. The values listed are at room temperature (25 C), nominal supply voltages.
Core and internal rail.
External rail.
The RTC typically fails when VBAT drops below 1.6 V.
Including voltage on outputs in 3-state mode.
V
3-state outputs go into 3-state mode when V
Accounts for 100 mV voltage drop in all supply lines.
Only allowed for a short time period.
