Related to KL27 Series Microcontroller

Hi,

We are doing microcontroller porting in our project.

New selected Part is MKL27Z32VLH4 from KL Series.

We are looking for an Interrupt on chip type functionality, can you suggest the pin for the above microcontroller which can be used as wake up from deep sleep mode?

Thanks & Regards

Hi Meghna,

    Could you tell me which chip mode you want to enter?

    Because deep sleep mode have a lot of chip mode: STOP, VLPS, LLS, VLLS3, VLLS1, VLLS0.

    To STOP and  VLPS, normal pin interrupt(Port interrupt) can wake up the MCU, you just need to configure the pin interrupt is OK, when the pin interrupt happens, the stop and vlps mode will exit.

    But LLS, VLLS2, VLLS1, VLLS0 should wakeup by the LLWU pin, please refer to table 18-1 in the KL27 reference manual:

  You can just use PTB0, PTC1, PTC3, PTC4, PTC5, PTC6, PTD4 and PTD6 in the according LLWU module to wakeup the low leakage stop mode.

Wish it helps you!

If you still have question, please contact me!

Have a great day,
Jingjing
