The MC44002/7 is a highly advanced circuit which performs most of the basic functions required for a color TV. All of its advanced features are under processor control via an I2C bus, enabling potentiometer controls to be removed completely. In this way the component count may be reduced dramatically, allowing significant cost savings together with the possibility of implementing sophisticated automatic test routines. Using the MC44002/7, TV manufacturers will be able to build a standard chassis for anywhere in the world. Additional features include 4 selectable matrix modes (primarily for NTSC), fast beam current limiting and 16:9 display.
