Low Frequency Limit for DDR2 and LPDDR2 on Arria V and Cyclone V Devices - Low Frequency Limit for DDR2 and LPDDR2 on Arria V and Cyclone V Devices Description This problem affects DDR2 and LPDDR2 products. For Arria V devices, DDR2 and LPDDR2 interfaces at frequencies less than 200 MHz will not operate correctly. For Cyclone V devices, DDR2 and LPDDR2 interfaces at frequencies less than 167 MHz will not operate correctly. Resolution The workaround for this issue is to not use frequencies less than 200 MHz for Arria V devices, or 167 MHz for Cyclone V devices. This issue will not be fixed.
