M66271FP - OPERATION PANEL CONTROLLER

Description

The M66271FP is a graphic display-only controller for displaying a high duty dot matrix type LCD which is used widely for PPC,FAX and multi-function telephones.

It is capable of controlling a monochrome STN LCD system of up to 320 x 240 dots.

Features

  • q Displayable LCD.
  • Monochrome STN dot matrix type LCD of up to 76800 dots (equivalent to 320 × 240 dots).
  • Maximum display duty : 1/240 (set to 240 Line) : 1/255 (Max) q Display memory.
  • Built-in 9600-byte(76800-bit)VRAM (equivalent to one screen of 320 × 240 dots LCD).
  • All addresses of built-in VRAM are externally opened.

MITSUBISHI M66271FP OPERATION PANEL CONTROLLER DESCRIPTION The M66271FP is a graphic display-only controller for displaying a high duty dot matrix type LCD which is used widely for PPC,FAX and multi-function telephones. It is capable of controlling a monochrome STN LCD system of up to 320 x 240 dots. The IC has a built-in 9600-byte VRAM as a display data memory. All of the VRAM addresses are externally opened. Address mapping in the MPU memory space allows direct addressing of all display data from the MPU,thus providing efficient display data processing such as drawing. The built-in arbiter circuit (cycle steal system) which gives priority to display access allows timing-free access from MPU to VRAM, preventing display screen distortion.
