INTRODUCTION S6D0144 is a single chip solution for TFT-LCD panel： source driver with built-in memory， gate driver and power circuits are integrated on this LSI. It can display to the maximum of 128-RGB x 160-dot graphics on 260k-color TFT-LCD panel. S6D0144 supports 18-/16-/9-/8-bits high-speed parallel bus interfaces and Serial Peripheral Interface （SPI）。 In addition， the LSI has 18-/16-/6-bit RGB interface for motion picture display. The motion picture area can be specified by Window Addressing Function. The specified window area can be updated selectively in order for motion picture to be able to be displayed independently of and simultaneously with still picture display. S6D0144 has various functions for reducing the power consumption of TFT-LCD system： The LSI operates at low voltage and has internal GRAMs to store 128-RGB x 160-dot 260k-color image data. Additionally， it has an internal booster that generates the TFT-LCD driving voltage， breeder resistance and the voltage follower circuit for TFT-LCD driver. S6D0144 is suitable for any medium-sized or small portable mobile solution requiring long-term driving capabilities such as digital cellular phones supporting a web browser， bi-directional pagers， and small PDAs.
