CC2642R: Migrating from CC2640 to CC2642R or CC2640R2F for BLE 5.0

Hi Team,

My customer has the following questions:

"If I have a board designed already with CC2640, can I use CC2642R without making layout change? Does balun and supporting components remain same?

How much code space is left over for application processing with CC2640R2F and CC2642R?"

Thanks,

Kevin
