1 / 111 page  - 1 - HM17CM256 128XRGBX82 OUTPUT LCD DRIVER IC with built-in RAM s INSTRUCTION HM17CM256 is a dot-Matrix LCD drive IC with 82 commons (80 + 2 icons) and 384 segments (128 X RGB) drive ports for 256 colors driving. This IC stores the serial or parallel BIT data transferred by the microcomputer on the built-in RAM (81,920 bits for graphic + 2048 bits for icons) and generates the signals to drive LCD panel. Color graphic display is achieved by selecting 8 gray (256 color) levels out of 32 gray palettes 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 164 x 128 display (maximum) is possible with master and slave application. s FEATURES 256 color bitmap LCD driver LCD drive outputs 128 ×RGB segments, 80 commons for graphic and 2 commons for icons Display RAM capacity 81,920bits (for graphic usage) 2,048bits (for icon usage) Gradation display 8 gradations can be selected from 32 gradations by PWM control Black/White display 82 × (128 × 3) bits display is possible 8 bit BUS interface directly connectable with 68 / 80 series CPU RAM data length 8 BIT / 16 BIT selectable Serial interface available Programmable duty / bias ratio with command Various instruction set display data read/write, display ON/OFF, positive/negative display, page address set display start line address set, partial display, bias select, column address set, all display ON/OFF, boosting selection, n line inversion mode read modified write, power save … Built-in voltage booster (programmable) : 7 × boosting Built-in voltage regulator Controllable contrast with built-in electric volume (128 steps) Low current consumption Logic supply 1.7V ~ 3.3V LCD drive supply 5.0V ~ 18.0V C-MOS silicon process Package bumped chip / bare chip Preliminary Specification(0.3) HM17CM256 EXTERNAL SHAPE 01/02/09 |
