CC3235MODSF: Replacement from CC3220MOD

Part Number: CC3235MODSF
Other Parts Discussed in Thread: CC3220MOD

Hi experts,

My customer is considering replacement from CC3220MODSF12MOBR to CC3235MODSF12MOBR. The concern of my customer is API. He thinks API of the basic operation is common to CC3220MOD and CC3225MODSF.

There are some extensions of CC3225MODSF compared with CC3220MOD. Is this understanding correct?

He would also like to estimate the man-hours required to design the software that controls CC3225MODSF. If there was a similar replacement at another company, how long did it take to realize it?

Do you have any information that would be helpful?

Best regards,

Shunsuke Yamamoto

  • Hi,

    Yes, you understanding is correct. CC3235 sl_ APIs are extension of sl_ APIs for CC3220. Extension is for new features only. That means you can run CC3220 code at CC3235 without big issue. Porting of code is pretty straight forward. Required steps:

    • update SDK version (if code for CC3220 was designed at old SDK without CC3235 support)
    • change linker file from CC3220 to CC3235 and compile new code
    • implement new features into code (e.g. support for 5GHz; but if new feature are not needed this step can be skipped)
    • create new Unifash image (changing CC3220 service pack to CC3235 service pack)

    If developer is experienced with CC3220 devices and he need exact same features at CC3235 it can take few hours. If CC3220 code is based on SDK which supports CC3235 required time will be under one hour. But if customer want to add new features (e.g. 5GHz) it can take a few days. Depending on what exactly he need and how well is CC3220 code designed.
