CAUTION:
When you start your own design (with unique PCB layout) and intend to use the LPDDR2 interface, you should target the 10M50DCF484I6G or 10M50DAF484I6G. For other Intel® MAX® 10 parts that support LPDDR2 interfaces (include any 10M16 or higher density Intel® MAX® 10 device, with dual supply, F256 or higher pin-count, and –i6 speed grade), the Intel® Quartus® Prime access to these parts requires you to contact your local Intel® (formerly Altera) sales person to provide you with a special .ini variable.
