  I am considering to use LPC54101 for a 8-bit 5 Msps ADC application for 20 ms. Is there any recommendation to use DMA to transfer those newly sampled data into external FIFO or SDRAM. LPC408x/407x come with external memory controller but not LPC54100.

  I think LPC4370, with external memory module, 12-bit ADC at 80 Msps would be a better choice. The challenge is the low-power operation. Any view?
