Low power accelerometer with shake detection

Hello,

Is there any low power compact accelerometer available from ST that can or configured to auto detect a shake like iPhone 'undo/redo shake' and interrupt host MCU to wake up. I don't want process accelerometer raw values on the MCU to save power. My current MCU is TI's CC2640.

Thanks,

I'm ST doesn't have accelerometer with embedded shake detection at this moment, but should release it soon.

How soon? You just released LIS2DW12.

And we've been waiting for it quite a bit of time

I'm not marketing guy

:)

but I will try to get more precise information.

Meanwhile do you realy need to recognize specific shake movement? Please be aware that our sensors has wake-up, or activity/inactivity detection which can be used for example to wake-up main device microcontroller.
