4076 - ECP5: While migrating device pinout from LatticeECP5-25 to LatticeECP5-85 device, how to handle the pins when some pins are notified as NC in LatticeECP5-25 and GND or RESERVED in LatticeECP5-85 device?
When migrating the device pinout from LatticeECP5-25 to LatticeECP5-85 devices, generally, the NC pins in LatticeECP5-25 pinout can be notified as GND or RESERVED pins in LatticeECP5-85.
If the LatticeECP5-85 pins are notified as GND, then you can connect the NC pins to GND. Whereas, if they are notified as RESERVED, then the pins can be left floating (not connected on board).

I/O pins which are unused in a design typically do not need to be grounded or connected anywhere. Some of the devices have global setting for pull-ups on I/O likes -Up, -Down or Bus-Hold, and others may have settings for each pin. By default, Lattice ...

No, you can connect the VMON pins directly to monitored voltages which are between 0 and 5.9V. Some of the Lattice evaluation board schematics do include a resistor between the monitored voltage and the VMON pins. This is typically only used with the ...
