For applications requiring extreme conservation of power, the CC26xx device features a power-
management system to efficiently power down the CC26xx device to a low-power state during extended
periods of inactivity. A power-up and power-down sequencer, a 32-bit sleep timer (a real-time clock
[RTC]), with interrupt and 20KB of RAM with retention in all power modes positions the CC26xx
microcontroller perfectly for battery applications.
