CC2564: Low Power modes for the CC2564

Yuri Cherniakov

Part Number: CC2564
Other Parts Discussed in Thread: CC256XB-BT-SP

Hello!

I am implementing a low power mode, Among other modules the host MCU (STM32L476) will go to sleep to save energy,

during this time i would like the CC2564 to consume the least amount of power but still remain able to receive data.

Please advise on how to do this - which power mode is best suited for this situation and how do i put the cc2564 into it?

Moreover, where can i find detailed documentation regarding the low power modes of cc2564?

thanks,

    Yuri,

    The CC2564 initscript (i.e. CC256XB-BT-SP) configures the device for low power mode. If the default initscript is used, the device will enter the lowest power mode whenever possible and wake up by either over the air activity or signal from the host.

    Best regards,

    Hello Vihang,

    Thanks for the quick response!

    I have follow up questions:

    1. Is it possible to set the host MCU in low power mode (so it does not communicate with the cc2564) and wake it up when new data arrives through BT?

    2. Let's presume that the host MCU is in low power mode, is it possible to expect the CC2564 to wake it up? if so,  using what method (interrupt?) ? 

    3. When CC2564 wakes up from the LPM, are there any re-initializations that have to be made to the in the CC2564?
