Device comparison table

[JohnBrown]

Having just seen a couple of questions relating to DMA, which I was not aware existed on the nRF51822, I did a bit of digging, and it seems there must be newer silicon versions than the one I'm using. Is there a table anywhere setting out the differences in the various devices?

Hi

Look at the PCN documents listed in the nRF51 compatibility matrix v1.1, table 3. They list the changes between the different nRF51 IC revisions. Table 2 maps nRF51 build codes to nRF51 revision. Build codes can be read on your nRF51 chip. How to understand the chip markings is documented in the nRF51822/nRF51422 PS v3.1, chapter about "Ordering information".

The DMA is documented in relation to the SPI slave interface. The SPI slave existed first on nRF51 revision 2.

Thanks for that very prompt and helpful answer. The Nordic documentation is great, but there is so much of it that sometimes the right part can be hard to find.
