TE0728 - DDR Settings

[chutson]

Hello,

Looking at the test_board example, the DDR is set to DDR3L and the MT41J256M16 RE-125.  In the schematic it is using 1.5V as the supply (instead of 1.35V for DDR3L) and there is a different part number NT5CC256M16CP-DI.  Are we advised to use the settings from the test_board example?  There is some mismatch between that and the datasheet.

Thanks,
Chris

Compared to the defaults from the test_board using MT41J256M16 RE-125 I believe the following changes are needed.

DDR3L -> DDR3
tRC = 48.91ns -> 50.625ns
tRASmin = 35ns -> 37.5ns
tFAW = 40ns -> 50ns
