If firmware/software need update after change NRF52840 footprint from QIAA to CKAA?

Hello Nordic Team,

Our existing device using NRF52840 QIAA,  we are plan to replace the QIAA package with CKAA package for size reduction.  After I went through the SPEC, I didn't find any firmware related difference between two package. Could your help to double confirm?

Thanks

Hello,

No changes if the external circuitry is the same.
