CC1310: How many security keys can be added to TI 15.4 coprocessor?

Eugene Peng

Part Number: CC1310

Hello,

I am using the TI 15.4 coprocessor example application as the coordinator. If I want a unique key between each end device with my coordinator, how many unique keys can I add into the PIB in the coprocessor?

And if the key table size is limited, what is the maximum size I can expand it to if I recompile the project?

Thanks!

Eugene,

Yes, the TI stack uses different keys for each link and this is why the coordinator need more RAM than the sensors in the system. Each link requires about 128 bytes of RAM to store keys and ID's on the coordinator.

Thanks you for the response.

It's good to know that each link requires 128 bytes of RAM. Do you know the maximum number of links that the coprocessor firmware can support?

About 50 for the CC1310.
