Hi Huizong,

NRF52832-QFAA-R has an APPROTECT vulnerability. This is fixed in NRF52832-QFAA-G-R.
This difference is common for all cases of comparison between ICs with and without the "-G-" in the Function Variant Codes of the IC marking.

Please use the variants with improved APPROTECT in all new productions. All of them are pin-compatible with their respective older variants.
