nRF52811 INFO.VARIANT - APProtect Available?

khelmutlord

Hello,

What would we expect the INFO.VARIANT FICR register's value to be with, for example, an nRF52811-CAAA-R7 vs. an nRF52811-CAAA-R7-B?

Right now I am seeing "AAA0" as the value in INFO.VARIANT--does this correspond to nRF52811-CAAA-R7?

Thanks,

Helmut Lord

    Hi,

    From the Ordering Information in the P.S, you can see how the labelling on a nRF52811SoC would be:

    For eg, if on the chip it is N52811CAAAA02020JG, then the VV = AA & HP = A0. Then the INFO.VARIANT would be AAA0.

    So it would depend on the SoC and you can find them out by looking at the marking on the chip.

    I don't have a R7 & R7-B with me at hand, but I can look around and check this internally. 

    Regards,
