Battery Life
Figure 1. Battery Life vs. VCC Supply Voltage
Notes:
1. TinyLogic® ULP and ULP-A with up to 50% less power consumption can extend battery life significantly.
Battery Life = (Vbattery•Ibattery•.9)/(Pdevice)/24hrs/day
where, Pdevice = (ICC • VCC) + (CPD + CL) • VCC2 • f.
2. Assumes ideal 3.6V Lithium Ion battery with current rating of 900mAH and derated 90% and device frequency at
10MHz, with CL = 15pF load.
