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. The set of the on-chip display RAM of 65 X 132 bits and a one-to-one correspondence between LCD panel pixel dots and on-chip RAM bits permit implementation of displays with a high degree of freedom.
