Hi,

Thank you so much for your interest in our products and for using our community.

Yes! The first way that comes to my mind is using the GPT timer as a wakeup source, for more detail please refer to app note AN13104 Debug and Application for i:MX RT1170 Clock and Low Power Feature. If the clock and the prescaler are not slow enough, the GPT counter can be operated using an external clock (GPT_CLK) from outside the device, which in turn can be generated with another timer.

Hope it helps you.

Have a nice day!
