Lattice Semiconductor
LFE2M50E/SE Logic Signal Connections: 484 fpBGA (Cont.)
* 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
(ECP2M20 and ECP2M35). They can be either sysCONFIG pins or general purpose I/Os. These pins are dedicated pins for the higher density
devices (ECP2M50, ECP2M70 and ECP2M100).
****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.
