I'm working on lab application with the following parameters: --adc converter 16Bits with 1MS/s (measureing time about 200s). --storing the data in SRAM, SIMM or equivalent and then write it to SD

I have some understanding problems of SPI (on DUE) 1. There are adc converters working with spi speed > 100MHz. Therefore the smaller SPI speed of the DUE is important. Which is the max. SPI speed of DUE? 2. Assuming this speed will be 16 MHz. Does this mean that I can read adc results by 16MHz/Bit :16Bit=1 MHz as desired? 3. If max. SPI speed is smaller, are there chances to use an external faster clock?

Storing data is a special problem as sram with desired amount are to expensive and to small and lead to a huge amount of chips. I'm working on that. Does anyone knows a solution with SIMMS?

Thanks!
