HM17CM4096 Preliminary Specification 128XRGBX162 OUTPUT LCD DRIVER IC with built-in RAM INSTRUCTION  EXTERNAL SHAPE HM17CM4096 is a dot-Matrix LCD drive IC with 162 commons and 384 segments (128 X RGB) drive ports for 4,096 colors driving. This IC stores the serial or parallel BIT data transferred by the microcomputer on the built-in RAM (248,832 bits for graphic) and generates the signals to drive LCD panel. Color graphic display is achieved by selecting 16 gray (16R 16G 16B = 4,096 color or 256 color mode ) levels out of 32 gray palettes HM17CM4096 independently. This IC is suitable for battery-operated system, hand-carrying information equipment by ensuring low power consumption, low power supply (1.7V ~ ) and a wide range of operating voltage. And 162 x 128 display is possible with j ust one chip. FEATURES
