ELECTRICAL CHARACTERISTICS

The following conditions are assumed unless otherwise specified:

VVBAT = 3.1 to 5.5V; VDD18 = 1.6 to 2.0V; VDDIO = 1.6 to 2.0V; VSS = 0V; TA = -40°C to +85°C

The current for 3.3V circuits is sourced at the VBAT pin, except when using an external 3.3V supply as shown in

Figure 5-7.
