GENERAL DESCRIPTION

The ML9059E is an LSI for dot matrix graphic LCD devices carrying out bit map display. This LSI can drive a dot matrix graphic LCD display panel under the control of an 8-bit microcomputer (hereinafter described MPU). Since all the functions necessary for driving a bit map type LCD device are incorporated in a single chip, using the ML9059E makes it possible to realize a bit map type dot matrix graphic LCD display system with only a few chips.

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)

? Display RAM capacity

65 x 132 = 8580 bits

? LCD Drive circuits

49 common outputs, 132 segment outputs

? MPU interface: Can select an 8-bit parallel or serial interface

? Built-in voltage multiplier circuit for the LCD drive power supply

? Built-in LCD drive voltage adjustment circuit

? Built-in LCD drive bias generator circuit

? Can select frame reversal drive or line reversal drive by command

? Built-in oscillator circuit (Internal RC oscillator/external clock input)

? A variety of commands

Read/write of display data, display ON/OFF, forward/reverse display, all dots ON/all dots OFF,

set page address, set display start address, etc.

? Power supply voltage

Logic power supply: VDD-VSS = 3.7 V to 5.5 V

Voltage multiplier reference voltage: VIN-VSS = 3.7 V to 5.5 V

(2- to 4-time multiplier available)

LCD Drive voltage: VBI-VSS = 6.0 to 18 V

? Package: Gold bump chip (Bump hardness: Low, DV)

: Gold bump chip (Bump hardness: High, CV)

? This device is not resistant to radiation and light.
