RAM size for MK61FN1M0CAA12R

abiabi — Mon, 29 May 2017 07:01:27 GMT

I am using MK61FN1M0CAA12R. I see MK61FN1M0VMJ12 CPU closer to this variant of K61 in Kinetis IDE and when I choose this for my project, I see that I have only 32KB RAM available.

Whereas, from datasheet I see that MK61FN1M0CAA12R supports upto 128KB RAM.

Can someone tell me what is the RAM size of MK61FN1M0CAA12R and how to configure it in Processor expert?

Hi Abi,

The default memory size of the project is correct, it is setting 128 KB of RAM (two regions with size of 0x10000)

Hope it helps!

Though 128KB RAM is available, I see only 52KB of heap can be used. Is there any restriction on the heap size and is there a way to allocate more heap?
