Calculation: Theoretical values when driving via li-ion battery at 3V and performing low-/high-speed/suspend (HALT) operations every 5 seconds in the following order:
1) Low-speed (32kHz) for 1.5s, 2) High-speed (1MHz) operation for 10ms, 3) suspend (HALT) operation for 3.49s.

OKI SEMICONDUCTOR's original low-power consumption technology results in the
industry's lowest current consumption during both normal operation and stop. In addition,
both dual- (selectable low/high speed) and triple- (selectable low/medium/high speed)
clock functionality are offered for longer battery life, while current leakage is prevented for
low current consumption throughout the entire temperature range.
Intermittent operation can reduce the average current consumption of the battery even if a current on the order of mA is required.
In this case OKI SEMICONDUCTOR recommends intentionally reducing operating time or increasing the operating frequency.
