MC13213 upgrade to KW2x

[arnogir]

Hello

I'm using a system with a remote and a coordinator.

The system is done with MC132213 and the Beestack (Slave/coordinator).

I know the new Kw2x allow to reduce power consumtion.

I think this will be great for my remote to increase battery live.

I have some question about an upgrade of my remote wfrom MC13213 to Kw2x (The coordinator will stay with MC13213)

1) Is the beestack with Kw2X is compatible to communicate with beestack MC13213? (In other word, is it ok to keep coordinator with MC13213 and change remote to Kw2X?)

2) My remote is only composed with MC13213 and BP. Then the MC13213 go to sleep to reduce consumtion (0.5µA). and then the Keyboard interrupt wakeup the µC.

After try, I thing the beestack with Kw2X is not possible to have a wakeup only with a Keyboard interrupt (External pin)?? I onlyfound with timer... I have right? What should be the solution?

Thank you

Hello ,

Answering your questions:

1) Yes, you won't have any problem.

2) The power consumption in the different operating behaviors can be consulted in the table 13 "Power consumption operating behaviors" in the MKW2x datasheet.

The wake-up sources can be consulted in the MKW2x reference manual in the table 10-14 "Wakeup sources for LLWU inputs", where you will notice that there are several wake-up sources.

I recommend you to take a look into the AWIC and LLWU modules in the reference manual. Also, I think that the application notes AN4470 and AN4503 will be useful for you.

Best regards,

Earl Orlando.

Hello

Thank for your support.

But I'm still always a question with the Beestack.

I don't find the good sleep configuration.

Which mode you advice me? My board will only have the Kw2x with an external BP and the antenna system. The aim is to put the board in a state to consume less as possible current and wakeup with a BP press. The the code should restart at the same point (no done a Reset action and restart from entry point code. THis to keep the Zigbee associating with the coordinator):

Hello Arnaud,

I think that the best mode for your application is LLS which allows the MCU to go to the same point where the system went to sleep. The VLLS modes have lower power consumption but the system is reset when it wakes up.

Regards,

Earl.
