nRF 52840 Product variant information

[Chaabane]

Hi,

I'm using nRF52840  where it's written 1.0.0 on the jlink ship and QIAAC0 on the nRF ship.

When reading the info.variant register I got 0x41414330 which is ..AAC0 but this reference doesn't exist in the datasheet ( rev 1.0) 4.4.1.9 INFO.VARIANT !  Is this normal ?

I'm planning to order some samples  of the same revision or higher but in mouser.fr for example they don't indicate the reference of the ship  ? is there  a way to figure this out ?

Thank you

Chaabane

Hi,

 

It seems that the documentation on variant might not have been updated with the C0 value.

 

At this time all chips that are available should be C0. I do not know why (some) distributors do not specify this, unfortunately this is outside our control so you need to contact the respective distributor if you want to confirm this.

 

Best regards,

Andreas

Hi,

it seems the documentation still doesn't show C0 variant in the datasheet, could you please check it?  4.4.1.9 INFO.VARIANT.

Also the SDK file nrf52_bitfields.h doesn't know about the C0 variant.

Do I miss anything?

Thank you for clarifications.

Hi,

 

Sorry for the late response, I am not given a notification when a 'verified answer' is responded to.

 

0x41414330 is a valid reading, and indicates AAC0.

 

Best regards,

Hi Andreas, would it be possible to update the official documentation to include this variant ? If all available chips should have this value, it would make sense that we can actually find it in the datasheet.
