The Feynman relativistic chessboard model is modified to describe a discrete interfacial system. The two-phase interface profile equation, the direct correlation function and the full free-energy density functional are solved exactly in the presence of an arbitrary field; this is the first discrete interface model for which one has the complete solution in a closed form. The continuum limit and the scaling behavior are also discussed.
