Lattice Semiconductor
* Supports true LVDS. Other differential signals must be emulated with external resistors.
** These dedicated input pins can be used for GPLLs or GDLLs within the respective quadrant.
*** For density migration, board design must take into account that these sysCONFIG pins are dual function for the lower density devices
****Due to packaging bond out option, this DQS does not have all the necessary DQ pins bonded out for a full 8-bit data width.
Note: VCCIO and GND pads are used to determine the average DC current drawn by I/Os between GND/VCCIO connections, or between the
last GND/VCCIO in an I/O bank and the end of an I/O bank. The substrate pads listed in the Pin Table do not necessarily have a one to one
connection with a package ball or pin.
