Novatek NT7501

The NT7501 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.

GENERAL DESCRIPTION

The set of the on-chip display RAM of 65 X 132 bits, and a one-to-one correspondence between the LCD panel pixel dots and the on-chip RAM bits, permits implementation of displays with a high degree of freedom. As a total of 133 circuits of common and segment outputs are incorporated, a single chip of NT7501 can make 33 X 100 dots displays.
