How long does MCU wake up from Register Retention mode?

[junma]

Hi all,

I want to know how long it takes for NRF24LE1 to wake up from low power mode, especially in these situations:

1) Wakeup from pin voltage level, from Register retention timers off/on mode:

2) Wakeup from TICK interrrupt, from Register retention timers off/on mode:
I see the specs that TICK wakeup time is related with the available clock sources in low power mode, so could you please list wakeup time consumptions in all the available clock source situations from Register retention timers on/off mode?

Thanks in advance!

Best regards, junma

Hi Junma,

I afraid we don't have any further information than what provided at chapter 11 in the product spec.

1. Wake up from pin: the start up time will be <100us.

2. Wake up from TICK: the CPU will wake up before the TICK happens, called pre-tick wakeup. This also <100us.
