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

So the STR71x parts do not have DMA support?

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: http://mcu.st.com/modules.php?name=mcu&file=pfinder&FAM=ARM7 Cheers, Hich :p
