DPM Setup

6.4.1

What is DPM

Dynamic Power Management (DPM) is a synthesis of breakthrough in ultra-low power technologies
that enable extremely low power operation in the DA16200. DPM shuts down all microelements on
the chip when not in use, which allows a near zero level of power consumption when not actively
transmitting or receiving data. Such low-power consumption can provide a battery lif e of one year or
more, depending on the application. DPM also enables ultra-low power transmit/receive modes when
the SoC needs to be awake to exchange inf ormation with other devices. Advanced algorithms enable
to stay asleep until the exact required moment to wake up to transmit or receive.

Enable DPM Mode

This section describes how to enable DPM mode.
1. Follow the steps in Section
a. During the setup, enable DPM as f ollows:
Dialog DPM (Dynamic Power Management) ? [Yes/No/Quit] : y
DPM factors : Defaults ? [Yes/No/Quit] : y
============================================
DPM MODE
Dynamic Period Set : Disable
Keep Alive Time
User Wakeup Time
TIM Wakeup Count
============================================
DPM CONFIGURATION CONFIRM ? [Yes/No/Quit] : y
Configuration OK
. done
NOTE
The default TIM wakeup count is 10 dtim:
10 dtim*102.4 = 1,024 ms = 1 sec @ DTIM = 1
(Assumed that AP DTIM = 3, 10 dtim is 921.6 ms)
Wakeup from sleep state takes place every second to check if a packet has been received.
b. Custom DPM f actors can be def ined during DPM setup as f ollows:
Dialog DPM (Dynamic Power Management) ? [Yes/No/Quit] : y
DPM factors : Defaults ? [Yes/No/Quit] : n
DDPS Enable ? [No/Yes/Quit](Default: No) :
DPM Keep Alive Time(0~600000 ms) ? [Quit] (Default 30000 ms) :
DPM User Wakeup Time(0~86400 Sec.) ? [Quit] (Default 0 Sec.) :
DPM TIM Wakeup Count(1~65535 dtim) ? [Quit] (Default 10) :
============================================
DPM MODE
Dynamic Period Set : Disable
Keep Alive Time
User Wakeup Time
TIM Wakeup Count
============================================
DPM CONFIGURATION CONFIRM ? [Yes/No/Quit] : y
