SimpleLink™ Wi-Fi® CC3220S Wireless Microcontroller LaunchPad™

Other Parts Discussed in Thread: CC3220S, CC3200, ENERGIA, CC3220SF

Hello everyone, I'm thinking of shifting from my cc3200 to cc3220s launchpad but I'm a bit confused evaluating
cc3220s and cc3200sf when it comes to understand how many flash resides on each one.

The problem is that both of ti pages provide the link to the very same hardware overview and schematic:

CC3220 SimpleLink™ Wi-Fi® LaunchPad™ Development Kit Hardware User's Guide (Rev. B)
CC3220 SimpleLink™ Wi-Fi® and Internet of Things Hardware Design Files (Rev. A)

where we can contemplate 4MB flash on board. Long story, but I have the following questions so far.

Does the 3220s lp have 4MB flash ?
If yes, will I be able to store there my specific file and persist my own data as I did in case of 3200 ?

Will I be able to migrate smoothly my 3200 code to 3220s ?

    Hi,

    What is your development IDE with CC3200. It is CCS/IAR or Energia? This is important point, cause there is a small issue with CC3220SF and Energia.

    My recommendation it to start development with CC3220SF LaunchPad. It have 1MB XIP (of chip) flash and allows to use up to 1MB code. CC3220S is similar like a CC3200. It have 256kB RAM and your code + RAM stuff need to fit into it.

    Migration from CC3200 to CC3220 depends on how your code is designed. But generally you should not expect big issue with migration. Migration guide is available.

    In addition to the details Jan mentioned about the on-chip memory, all CC3220 LPs do have 4MB of on-board flash that is external to the IC which can be used for storing your own specific files/persistant data.

    Best,

    I use CCS so hope it will not be an issue, thanks for the answer.
