CC3220SF: Alternatives to the CC3220SF in the TI lineup

Part Number: CC3220SF
Other Parts Discussed in Thread: CC3235SF, CC3551E

Tool/software:

Hello,

We have been using the MCU CC3220SF for our applications on the past few years, it is a serviceable and efficient part, however we feel like it is becoming a bit outdated. Therefore we have been looking for suggestions on other TI MCUs that we could use in its place. Our requirements are:

  • It needs to support RTOS
  • It needs to have WiFi capabilities
  • Better performance and support than the CC3220SF

It'd be nice if it was compatible with 5G from the box. 

Any suggestion will be highly appreciated.

    Hi Daniel,

    As successor of CC3220SF we can talk about two types of devices.

    CC3235SF

    • it will add capability of 5GHz and 16 TLS sockets
    • CC3235 use same SDK as CC3220SF and transition will be pretty simple
    • but there will be same limitations as CC3220SF (NWP supports TLS 1.2 only, EAP security supports TLS 1.0 only)
    • SDK is at LTS state (that means no new features but only security fixes). This is same as CC3220

    CC3551E

    • brand new device including 5GHz and BLE and WiFi-6
    • less mature platform, software side is still at development
    • higher permeance of MCU (Cortex-M33@160MHz) and some new features
    • TCP/IP and TLS stack at host MCU not inside NWP like at CC3220
    • this device is a "future", but harder transition from CC3220 than CC3235
