CC3200: CC3200 + Ethernet

Gregory Duperon
Expert 7600 points
Part Number: CC3200
Other Parts Discussed in Thread: CC3120, CC3120BOOST, MSP-EXP432E401Y

Can you comment on the necessary chipsets necessary to enable Ethernet alongside the CC3200?

Does the CC3200 have the capability to handle the Ethernet stack and the customer simply add the PHY?

I've seen some suggestions to use CC3X00 + TM4C1294?  Is this the best way to go about going it?

Thanks.

    Hi Gregory!

    I would not recommend running the Ethernet stack on a CC3200 simply because of memory constraints. Doing this could significantly reduce the amount of (or exceed) memory available on the CC3200 for another application, making it difficult or impossible to run both Wi-Fi and Ethernet together.

    A solution with a CC31xx and another host supporting Ethernet would be better because the Wi-Fi stack (network stack, TLS/SSL, MAC, and PHY) is embedded in ROM on the CC31xx and the host would only need to support the smaller SimpleLink Wi-Fi host driver to control it.

    I would recommend you take a look at the MSP432E4 + CC3120. We have a simple example of this type of use case in the available SDKs for the devices. To take a look at it, download the following:

    1. The SimpleLink MSP432E4 Ethernet MCU SDK
    2. The SimpleLink Wi-Fi CC3120 SDK Plugin

    Go into the Wi-Fi plugin install and look at examples\rtos\MSP_EXP432E401Y\demos\ethernet_wifi_tcp_echo\README.html for a short overview of the example. The example can be run with the MSP-EXP432E401Y LaunchPad and the CC3120BOOST BoosterPack.

    Best Regards,
