Notes:

1. Lifetime calculation assumes 4.0

μA (typ) current consumption for 32.768 kHz (RTC) operation, where 4.0 μA (typ) is the sum of 1.5 μA

(typ), consumed by the SLG3NT3342 to provide RTC clock, and 2.5

μA (typ), consumed by the RTC logic device (provided via VOUT pin).

2. Exact values depend on the battery manufacturer (Refer to the battery datasheet for details)
