Part Number: MSP432E401Y
We are considering using the MSP432E401Y as a common controller for providing ethernet connectivity for several PCBAs in a complex machine design. It is critical in this role that the MSP432 be compatible with existing HW. On several PCB's we use the Delfino (TMS320F28379D) for sampling and processing sensor inputs. Specifically the Delfino'ss McBSP is used to communicate processed ADC sample information downstream for further processing. If we select the MSP432, we will need the delfino to communicate with the MSP432E401Y microcontroller.
The current application has the Delfino using its McBSP as a transmit only port configured to drive its transmit clock, frame sync and data running at 50Mbps. Is the MSP432's QSSI peripheral's receiver compatible with a McBsp transmitter and one running at 50Mhz? Looking at the MSP432 data sheet, I see no timing information on the frame sync (its shown in diagrams but does not seem to specify any timing info in the tables). Further both the data sheet and technical reference manual speak of "Legacy" modes where the max serial clock rate looks to be only 10MHz and appears to behave more like an async transfer with requirements that the SysClk must be 12X the SSI clock.
Can you speak to the McBSP compatibility as a slave receiver to a McBSP transmitter at preferably 50Mbps rates (minimum continuous speed of 24Mbps)? If it is compatible, can you recommend mode of operation and configuration settings?
BTW: We are aware of the new Delfino (F28388) with ethernet connectivity. It is very possible that it could serve the role of a common ethernet interface and we will be posting some questions we have on it soon. It NOT being production released is a real concern for us and we are investing other avenues like the MSP432. I did not want to confuse this particular post by encapsulating it inside a larger conversation (at least to start) but I wanted you to be aware and am glad to discuss the F28388 if it makes sense to you as well.
Thank you in advance for your support.
