The estimated (core) power usage for Low Power FFD are shown in the table below. Additional power savings may be possible using Sensory’s Low Power Sound Detect (LPSD) option which approaches sub-50mW operation in Low Power mode. These measurements will vary based on component tolerances and any user added code and/or user added compile options.
