3.3 Recommended Operating Conditions
Table 3-3 lists the recommended operating maximum ratings.

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. The following list defines abbreviations used in
the table:
• 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
• Min: Minimum value
• Max: Maximum value
