ML9445 - 180-Channel LCD Driver

Description

The ML9445 is an LSI for dot matrix graphic LCD devices carrying out bit map display.

This LSI can drive a dot matrix g raphic LCD di splay panel un der t he con trol of an 8- bit microcomputer (h ereinafter des cribed MPU ).

Features

  • Direct display of the RAM data using the bit map method Display RAM data “1” Dot is displayed Display RAM data “0” Dot is not displayed (during forward display).
  • Dis play RAM capacity 65 × 180 × 2 = 23,400 bits.
  • LCD Drive circuits 65 common outputs, 180 segment outputs.
  • MPU interface: Can select an 8-bit parallel or serial interface or I2C (Write Only).
  • Built-in voltage multiplier circuit for the LCD drive power supply.
  • Built-in LCD drive.

FEDL9445-02 Issue Date: Dec. 20, 2013 ML9445 180-Channel LCD Driver with Built-in RAM for LCD Dot Matrix Displays GENERAL DESCRIPTION The ML9445 is an LSI for dot matrix graphic LCD devices carrying out bit map display. This LSI can drive a dot matrix g raphic LCD di splay panel un der t he con trol of an 8- bit microcomputer (h ereinafter des cribed MPU ). Since all the functions necessary for driving a bit map type LCD device are incorporated in a single chip, using the ML9445 makes it possible to realize a bit map type dot matrix graphic LCD display system with only a few chips.
