Advancements in technology for chip manufacturing are leading to the device which incorporates various functionalities within single chip. So as to reduce the complexity and size of the overall printed circuit board. Keeping the same idea in mind, lots of embedded project require to interface with 16x2 LCD or character LCD, which is one of widely used LCD available in market, with growing complexity and need to provide lots of functionality within the same size, the pins provided on the controller remains same, now it become difficult to share pins of the controller, the present work reflects about the working model which describes a technique to reduce the pin requirements of pin hungry interfaces for example considering 16x2 LCD normally if one has to interface such LCD�s, they need to dedicate at least 6 pins or at maximum 11 pins of a controller. Since we are moving towards lesser number on to pin�s, thus we want to take initiative towards development of such device.
