HWID 0x0086

[Gerbert Shnauer]

Hello,

I looked through "nRF51 Series Compatibility Matrix" document Version 2.1 and didn't find information about chip with HWID 0x0086. This chip is integrated into the nRF51 Development Board. Is there the updated version of the document?

[RK]

There's a useful file embedded somewhere in the nrf windows software called nrf51deviceids.xml, I don't remember where exactly, found it in a post here a few months ago.

That helpfully gives lots of information

 <Hardware hwid="0x0086" device="nRF51422" packet="QF" variant="AC" buildcode="A10"/>

This doesn't give any information about specifics of the chip.

[RK]

What specifics do you think that doesn't tell you? It tells you it's a QF, so that's the package, it's an nrf51422, that's the chip, it's the AC variant, so that's 256kB flash + 32kB RAM and it's build code A10 which isn't terribly useful to know. All that puts the chip in the '3' revision category from the compatibility matrix document. That document even tells you the HWID on the line is for the A00 build code and if the middle digit isn't '0', which in this case it's not, the HWID will be different, which it is.

What more information did you want?

[Gerbert Shnauer]

Thank you for the information that you provided.

I expected a list of erratum for this type of the chip. Also I would like to know how many UART buffers in this revision.

[RK]

The errata are in the Product Anomaly document which was updated for revision 3, which the HWID tells you this chip is, and the UART specification is in the nrf51422 (or nrf51822) product specification sheet and the nrf51 series reference manuals. All of those documents are linked off the 'SDK and Documentation' link at the top of the page.
