nRF52833-QIAA-R Compatability with NRF24L01+

[Tikullp]

Dear Sir/Madam,

I have already developed an RF communication device with an NRF24L01+ device. And I want to migrate to nRF52833-QIAA-R. For that, I have the below questions. Please revert soon.

1. Does nRF52833-QIAA-R have backward compatibility to communicate with the NRF24L01+ device?

2. Is the NRF24L01+ device going to obsolete?

3. When will nRF52833-QIAA-R be available in smaller versions of 5mm*5mm size?

Thanks and Regards,

Twinkle Panchal

Hi,

1. Yes, as mentioned in the nRF52833 Product Specification:
   
   • On-air compatible with nRF52, nRF51, nRF24L, and nRF24AP Series
2. We do not have a habit of obsoleting parts. This only happens if the chip has a direct replacement and/or the chip is not being ordered for a long time. There is still plenty of products using this chip, so I do not think it will be obsoleted anytime soon.
3. QIAA refers to the aQFN73 7x7mm package version, this will not be available in smaller size. 5x5mm QFN40 package is available as variant QDAA (nRF52833-QDAA-R), see the compatibility matrix.

Best regards,
Jørgen

Dear Jorgen Holmefjord,

As the IC nRF52833-QDAA-R will not be available in near future with major distributors, can we get the samples of them?

You need to contact you regional sales manager for help with that.

If you do not know who that is, please send me private message with your location, and I will provide you with contact details.
