I am working on SW for a product that is based on iMX6 Dual Lite processor.
SDRAM clock frequency is 400MHz (clock cycle 2.5ns).
We are planning to change SDRAM to a bigger one and one candidate for the new SDRAM is a DDR3-1866 (-107) component.
Timing values for this SDRAM are; tRC for it is 47.91ns, tRAS is 34ns and tFAW is 35ns (2KB page size).
MMDC configuration values would then be tRC=20CK, tRAS=14CK and tFAW=14CK, respectively.
Is this correct? Would these values work ok on our HW?
