Do the STR7 series parts have a DMA controller or equivalent? It probably does and I just missed it, but I don't see it in the documentation for the part.

Hello,

In the STR7xx family, for the moment we have already STR720 support a DMA controller.

The DMA controller provides access to 2 data streams inside STR720 system, each data stream can be associated to one particular peripheral, which triggers a DMA request starting the data transfer between the corresponding buffers defined in the stream descriptor.

Hope that this can Help you

Hich, :p

Hi Delphi_Pete,

Sorry, as I said for the moment only the STR71x support a DMAC but also we have STR730 product which will be available on the market soon, it support a DMAController.

For more information concerning the STR7xx family you can see:

Hello,

STR73x family is not published yet, but the STR73x package will be available soon and then you can find all the peripherals characteristic in the reference manual which will be available on the web page.

Thank you for your comprehension.

Cheers,

Hich 😉
