ELECTRICAL CHARACTERISTICS (continued)
(VCC = 2.0V to 5.5V, VCC = active supply (see Table 1), TA = -40°C to +85°C, unless otherwise noted.) (Typical values are at VCC =
3.3V, VBAT = 3.0V, and TA = +25°C, unless otherwise noted. TCXO operation guaranteed from 2.3V to 5.5V on VCC and 2.3V to 3.8V on
VBAT.) (Notes 1, 2)
