CC3220MOD: Kindly confirm, can we replace CC3220MODSF12MOBR with CC3200MODR1M2AMOBT

Part Number: CC3220MOD
Other Parts Discussed in Thread: CC3200MOD, CC3200, , CC3235MODS

Hi,

We are using CC3220MODSF12MOBR in our existing design/boards. Due to no stock and urgent requirement we need to replace with available part. PFA the existing Schematic.

We found CC3200MODR1M2AMOBT which available in Stock.

1. Kindly Confirm, Can we replace CC3220MODSF12MOBR with  CC3200MODR1M2AMOBT without doing any Modifications?

2.  CC3220MODSF12MOBR and  CC3200MODR1M2AMOBT both matches Pin to Pin and Footprint right? (We don't need FLASH pins.)

3. What is the difference between CC3220MODSF12MOBR and  CC3200MODR1M2AMOBT?

4. CC3200MODR1M2AMOBT having 1Mb Flash and 256K RAM? 

5. Kindly suggest if any Alternate part with Direct Pin Pin replacement for CC3220MODSF12MOBR?

6. If we procure from Unauthorized suppliers, How we can believe/Verify the component whether it's Original and New? 


 
Thanks and regards,

  • Hi Naveen ,

    A quick comment(s):

    1. CC3200MOD is pin compatible with CC3220MODSF but it is not compatible at software side. You will need to port your code for CC3200 from CC3220. Required effort depends on features inside your code. It may to be easy, hard or even not possible.

    2. Yes both modules are pin compatible.

    3. CC3200 devices are 1rst generation of devices. It uses different host driver, different peripheral drivers (drivelib vs TI Drivers), it supports lower number of sockets, it does not support IPv6 and WPA3, different way for OTA, etc.

    4. CC3200 does not have XIP (execution flash like a CC32xxSF devices). It uses 256kB RAM for code execution and data. CC3200MOD have 1MB internal SPI flash instead 4MB at CC3220MOD.

    5. Best replacement for CC3220MODSF is CC3235MODS. CC3235MODS does not have 1MB XIP flash, but if your code is not big, CC3235MODS can be a easy replacement (if we not count certification). CC3235MODS devices are at stock somewhere still.

    6.There is not a easy way how to validate that device is new or wasn't refurbished somehow. You can visually inspect genuine and device from gray market and test them at your application. It make sense compare devices with removed shielding as well. But with devices from gray market you cannot be sure at 100%.

    (btw... I am not a TI employee)

  • Naveen,

    You should procure from an authorized supplier to ensure you have an original TI device.
