MSP432E401Y: Ethernet with SPI interface

Part Number: MSP432E401Y
Other Parts Discussed in Thread: SYSCONFIG

Do we have a MSP432E4x solution that can compete with KSZ8851SNL/SNLI - Single-Port Ethernet Controller with SPI?

Data rate is not important could be just 1Mbit.

    Hi Bernd,

    I am not sure whether we have this solution. There are some code examples in the resource explorer. However, I do not think it is compatible with KSZ8851SNL/SNLI.

    Best regards,

    Hi Cash,

    I don´t look for a compatible solution, I look for a Ethernet controller with SPI interface.
    MSP432E4x has SPI and Ethernet plus PHY so I just want to know what additional effort the customer has to spend.

    Do we have an easy to implement software solution for that without spending man days for software development?

    Regards Bernd

    Hi Bernd,

    It looks like the part you mention is basically a Ethernet/SPI converter. The MSP432E device includes both 10/100 Ethernet and SPI as you mention. While we don't have an off-the-shelf example for doing SPI to Ethernet. However, the building blocks for this are there - we provide TI Drivers for the MSP432E for SPI as well as an Ethernet stack, and these can be configured using SysConfig GUI as a starting point to get everything initialized. So I'd recommend: 

    Go to sysconfig for MSP432E - you can see this on the cloud here but also in CCS desktop. https://dev.ti.com/sysconfig/#/start Select the MSP432E device and SDK. 

    Then, in the sysconfig GUI you can use the graphical interface to add and configure the SPI and add and configure the Ethernet stack components. At the end, sysconfig can spit out a project with configuration code into CCS, and then you'll need to add some code for using the SPI/Ethernet together (e.g. moving data around, using RAM for a buffer for the packets you want to send, etc). 

    I hope this helps give a bit clearer path. 

    Regards,

    Hi Katie,

    thanks for clarification.

    The Microchip part is the MAC and PHY in one device. It talks to a microcontroller over SPI. The micro still has to run the whole Ethernet stack. It is really designed for microcontrollers and microprocessors which do not have any 10/100 Ethernet hardware built in.

    The MSP432E has both MAC and PHY built in, so there is no need at all for the Microchip part. You still have to implement the Ethernet firmware stack.
