MIG Spartan-6 MCB LPDDR - Is Deep Power-Down mode supported?

Description

For LPDDR, it can be useful to put the chip into Deep Power Down mode when it is not in use to save power. 

While MIG MCB supports LPDDR SDRAM, there is no option in MIG to make the controller put the RAM into Deep Power-Down. 

Is this feature supported?

Solution

Deep power-down mode is not supported and there is no plan to support it. 

Any other sort of power saving hooks and techniques are to be implemented by the designer.

Self Refresh or Suspend mode can be used for power saving instead.

Please refer to the MCB Operation section in the Spartan-6 FPGA Memory Controller User Guide for these two modes.
