Electrical Characteristics
Electrical characteristics table limits are guaranteed by production testing, design, or correlation
using standard statistical quality control methods unless otherwise stated. Typical (Typ)
specifications are mean or average values 25 °C and are not guaranteed.
Unless otherwise noted: VBAT = 3.7 V, VDD_SYS = 3.7 V, VDD_PWR = 5.0 V, VDDIO = 1.8 V, and
TA = -40 °C to 85 °C.
