Battery Life vs. VCC Supply Voltage
TinyLogic ULP and ULP-A with up to 50% less power consumption can
extend your battery life significantly.
Battery Life = (Vbattery *Ibattery*.9)/(Pdevice)/24hrs/day
Where, Pdevice = (ICC * VCC) + (CPD + CL)* VCC2 * f
Assumes ideal 3.6V Lithium Ion battery with current rating of 900mAH and
derated 90% and device frequency at 10MHz, with CL = 15 pF load
