For many small, portable Internet of Things (IoT) applications, the “Holy Grail” is wireless connectivity with a battery life of up to 10-years, using a coin cell. This is not an easy task, as most inexpensive coin cells offer a maximum capacity of only ~ 240 mAh. By selecting a radio SoC with low sleep current consumption, 10 years is very achievable for both short and long-distance wireless connections.
