674 - POWR1014/A: Why should user avoid supply power to POWR1014's VCCPROG pin when VCCA and VCCD pins are powered on?
Description:
Power must NEVER be supplied to the VCCPROG pin when VCCD and VCCA are powered on. Operation under these conditions is undefined and may result in erroneous operation.
User should supplied power to the VCCPROG pin on POWR1014 only when POWR1014's board is powered off.
The intended purpose of the VCCPROG pin is to permit the POWR1014 to be given its initial program prior to applying power to the board. Power for the VCCPROG input should be supplied by an off-board power supply.

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 do not need to add a ferrite bead between your VCC regulator output and the VCC pins on the FPGA. There are two reasons for not adding the ferrite bead, the first being that the VCC pins are less susceptible to power supply noise so they do ...

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 ...
