Introduction
Chipcon RF-ICs operate with supply interface of a CC1000 RF transceiver to a
voltages lower than the old industry- 5 V microcontroller as an example,
standard 5V. Running at a lower voltage although the information is general and
enables the ICs to be less expensive and applies to all situations where two digital
have lower power consumption than they ICs with
