7 Low Power Operating

7.1 Duty Cycle Operating Mode

The CMT2310A allows Duty Cycle mode operating for both Tx and Rx by configuring related registers for power saving
purpose.
The Rx Duty Cycle includes 5 modes as follows.
1. Fully manual mode.
2. Automatic wake-up from sleep, then switch to manual control.
3. Automatic wake-up from sleep, then enter Rx and then exit Rx manually.
4. Automatic wake-up from sleep, then enter Rx and then exit Rx automatically.
5. Fully automatic mode.
The Tx Duty Cycle includes 3 modes as follows.
1. Manually enter TX, then automatically exit TX
2. Automatic wake-up from sleep, then switch to manual control.
3. Fully automatic transmission.

7.2 Super-low Power (SLP) Rx Mode

The CMT2310A provides a series of options helping users achieving super-low power (SLP) Rx to meet different application
requirements. All these options are available only when RX_TIMER_EN is set as 1, namely Rx counter is active. The main
purpose of SLP Rx is to minimize Rx time when no signal is received meanwhile properly extend Rx time when valid signal is
received, thus to accomplish stable data receive with minimum power consumption.
In general, traditional short-range wireless transceiver systems apply the solution as shown in the figure below to fulfill low-power
transceiver. The CMT2310A supports this fundamental solution as well. Moreover, based on this solution, the CMT2310A
extends 13 solutions with more favorable power consumption performance. The fundamental solution is detailed as follows.
