3.3 Recommended Operating Conditions

Table 3-3 lists the recommended operating maximum ratings.

Table 3-3. Recommended Operating Maximum Ratings

Parameter Min Typ Max Unit

Main battery supply voltage 2.7

(1)

3.6 4.5 V

Backup battery supply voltage 1.8 3.2 3.3 V

Ambient temperature range –40 85 °C

(1) 2.7 V is the minimum threshold for the battery at which the device will turn OFF. However, the minimum voltage at which the device will

power ON is 3.2 V ±100 mV (if PWRON does not have a switch and is connected to VBAT) considering battery plug as the device

switch on event. If PWRON has a switch then 3.2 V is the minimum for the device to turn ON.

3.4 Digital I/O Electrical Characteristics

Table 3-4 describes the digital I/O electrical characteristics.

• RL: Reference level voltage applied to the I/O cell

• VOL: Low-level output voltage

• VOH: High-level output voltage

• VIL: Low-level input voltage

• VIH: High-level input voltage
