Novatek NT7502

The NT7502 is a single-chip LCD driver for dot-matrix liquid crystal displays which is directly connectable to a microcomputer bus. It accepts 8-bit serial or parallel display data directly sent from a microcomputer and stores it in an on-chip display RAM. It generates a LCD drive signal independent of the microprocessor clock.
