CC1312R7: WiSUN solution and its future

Thiago Rocha

Part Number: CC1312R7
Other Parts Discussed in Thread: CC1314R10,

Since the actual limiting factor of your WiSUN implementation is the RAM size of the BR MCU (100 nodes for the CC1312R7), and since the upcoming CC1314R10 will have a bigger RAM size, I have some questions:

  1. Are there any plans to optimize the actual storage method used for the routing table to save memory?
  2. Will the BR implementation actually supported by the CC1312R7 still be limited to only 100 nodes as newer devices come?
  3. Is there any estimate as to how many nodes a CC1314R10 BR implementation will support on its network?
  4. Where can I find more information about the CC1314R10 and its specs?

We actually have a solid implementation running with your WiSUN solution, but the maximum number of nodes is a limiting factor that could be a deal breaker for a field trial/implementation.

Thanks for your help as always,

Thiago.

    Thiago,

    you are right that a border router will be RAM limited in terms of the number of nodes it can support. For CC1312R7 we recommend max 100 nodes, and the upcoming CC1314R10 should support approx 300 nodes. It should be publicly available some time first half of this year, you will have to wait for that to get access to more information. Longer term we will be working on solutions that can hold even more nodes.

    It is worth mentioning that multiple border routers can use the same network name, and thus also provide redundancy for your network. This is how you can build a larger WiSUN FAN (field area network) consisting of multiple PANs (personal area networks). A 1000 node FAN network could consist of 10 PANs, for example. Your data throughput requirements per node may also be a limiting factor in how many nodes it is wise to deploy per border router.

    Can you tell me if the CC1314 will be pin-to-pin compatible with the actual CC1312R7? If that's the case, we could just change our BR to run with the newer MCU.

    Yes, there will be a pin compatible version in the same 7x7 package. Same ref design will be used.
