Typical ratings are not guaranteed. The values listed are at room temperature (+25 ˚C), nominal supply voltages.

[2]

Core and internal rail.

[3]

External rail.

[4]

The RTC typically fails when VBAT drops below 1.6 V.

[5]

Including voltage on outputs in 3-state mode.

[6]

VDD(3V3) supply voltages must be present.

[7]

3-state outputs go into 3-state mode when VDD(3V3) is grounded.

[8]

Accounts for 100 mV voltage drop in all supply lines.

[9]

Only allowed for a short time period.

[10] Minimum condition for VI = 4.5 V, maximum condition for VI = 5.5 V.

[11] Applies to P1.25:16.

[12] On pin VBAT.

[13] To VSS.
