Reference Design LogoThis reference design provides a processor interface to the common dot-matrix LCD module. The on-chip oscillator available on some Lattice CPLD or FPGA families can further simplify the implementation by eliminating the need for an external clock source. This design is also suitable for low-power applications together with Lattice zero-power CPLDs.
