PSoC 5, 3 & 1 MCU

I wish to attach an external A/D to the PSOC5LP. The external A/D is running at 20MSPS and has an 8 bit parallel output. Would a EMIF and a DMA channel be the best bet?

DMA would be sufficient, you don't nened EMIF (unless the ADC you are using has a real memory-style interface which I doubt).

Thanks for the prompt response. My problem is simple. I assume I connect the A/D to a 8 pin port.  I place a DMA component on the schematic. I fire up the DMA wizard. The destination is SRAM, but what is the source?

   

Thanks,

Add a status register connected to your port. The the DMA source is StatusReg_Status_PTR.
