4.4. MAX® 10 Low Power Feature

The MAX® 10 low power feature is automatically activated when the self refresh or low power down modes are activated. The low power feature sends the afi_mem_clk_disable signal to stop the clock used by the controller.

To conserve power, the MAX® 10 UniPHY IP core performs the following functions:

  • Tri-states the address and command signals except CKE and RESET_N signals
  • Disables the input buffer of DDR input
Note: The MAX® 10 low power feature is available from version 15.0 of the Quartus® Prime software. To enable this feature, regenerate your MAX® 10 UniPHY IP core using the Quartus® Prime software version 15.0 or later.
