HD66729 - Low-power 105 x 68-dot Graphics LCD Controller/Driver

General Description

The HD66729, 105-by-68 dot-matrix graphics LCD controller and driver LSI, displays graphics.

It can be configured to drive a dot-matrix liquid-crystal display under the control of a microprocessor connected via a clock-synchronized serial or 4/8-bit bus.

Key Features

  • Control and drive of a 105 ´ 68-dot-matrix graphics LCD enabling quintuple power boosting from a single 1.8-V power supply.
  • Partial-display and centering-display modes in which a part of the display area is selected and driven by using a low-duty ratio.
  • Fixed display of several graphics icons (pictograms) at the top of the screen.
  • Low-power operation support: Ñ Vcc = 1.8 to 5.5 V (low voltage) Ñ VLCD = 4.0 to 13.0 V (liquid crystal drive voltage) Ñ Double, triple, quadruple,.

HD66729 HD66729 (Low-power 105 x 68-dot Graphics LCD Controller/Driver) Preliminary Rev 0.4a June 25, 1999 Description The HD66729, 105-by-68 dot-matrix graphics LCD controller and driver LSI, displays graphics. It can be configured to drive a dot-matrix liquid-crystal display under the control of a microprocessor connected via a clock-synchronized serial or 4/8-bit bus. The HD66729 has a partial display mode that selects and drives part of the display area by using a low-duty ratio, a centering display mode that places the LCD drive position at the center of the screen, a smooth vertical-scroll display mode and a double-height display mode for the remaining bit-map areas. It continuously displays several of the graphics icons so that the user can easily access a variety of information.
