MSP432E401Y: Is it possible to achieve high speed continuous data transfer in MSP432E401Y?

Part Number: MSP432E401Y

Hi,

I have a project where I sample 16 bits of data with the External Peripheral Interface in general mode and store it with DMA in ping pong mode.
The stored data can be send to the computer with the emac API.

My goal is to achieve high speed continuous data transfer with a sample frequency of 15 MHz. 

With my current implementation I have continuous data transfer at around 5 MHz (Sample frequency). 

Is the MSP432E401Y capable for this application?

With kind regards,

Wishu

  • A sample rate of 15Msps * 16-bits/sample sounds like 240 Mbps, while the theoretical maximum on the Ethernet is 100Mbps.

    5Msps * 16-bits/sample is about 80Mbps, which is probably pretty close to true Ethernet capacity.

  • Hello Wishu,

    I see you're wanting to use the EPI in general mode. According to page 1087 in the TRM, data rates up to 150 MB/s can be supported. As Bruce mentioned, you're needing to transfer ~240 Mbps which is 30 MB/s. So, on paper, the EPI should be able to handle this throughput.

    Regards,
