nRF51822CDAB versus QFAB

[Jack Gratteau]

Have previously used the QFAB. Are there any settings in the compiler or debugger that need to be different ? - my understanding is that xxAB refers to both.

Understand that light sensitivity of CD package requires post assembly coating - aside from Radio and some impact on analog, any other affect ?

Does light affect LF or HF clocks ? RC versus XTAL ?

Thanks

Hi Jack

No, there should not be any changes in the way compiling or programming a WLCSP package versus a QFN package. If you don't protect the chip from light properly it can cause the RF carrier to drift in frequency, and therefore make the radio not work. As far as I know, this will not affect the internal clocks though.

The external clocks are the same as for the QFN package, so they are not affected by light. 

Best regards,
