How to read K60 mask set?

cfgmgr — Mon, 30 Mar 2015 20:38:43 GMT

Is there some way to determine (at boot time) the mask set of my K60 silicon? Do I use REVID?

I have some boards with 120Mhz masks, and some with 150Mhz masks, and I want to be sure that I setup the MCGOUTCLK for the proper max frequency.

How do I interpret the value returned from REVID?

Many thanks

Hi,

You can use the REVID field to determinate the silicon version of your device. There is no way to check the core max frequency. Please refer to this thread, it might be useful.

Hope this information can help you

Thanks so much for your quick reply, Adrian. Sadly, you've confirmed what I suspected - there is no way to determine max frequency.

My application case is rather limited to K60 devices with FPUs; Although our current systems use 150Mhz K60s, I do need to support older batches of hardware that were built with 120MHz devices. I was hoping to be able to detect which device was present at boot time, and adjust MCGOUTCLK max freq accordingly. It sounds like you are saying that there is no way to do that. Pity.

On a different note, is there a document that summarizes the differences in revisions for all the K-series devices? I am looking for something like EB782, but I see that EB782 is for 100Mhz non-FPU devices. Is there a similar document for the 120Mhz and 150MHz devices with FPUs?

Thanks again,

-bill

Hi,

I am afraid we do not have such document. Please take a look a this document it might be helpful: AN4526.
