GENERAL DESCRIPTION

The ML9050/9051 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. Since all the functions necessary for driving a bit map type LCD device are incorporated in a single chip, using the ML9050/9051 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

? Display RAM capacity

ML9050/9051: 65 · 132 = 8580 dots

? LCD Drive circuits

ML9050: 65 common outputs, 132 segment outputs

ML9051: 49 common outputs, 132 segment outputs

? Microcomputer 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 power supply adjustment circuit

? Built-in LCD drive bias resistors

? Line reversal drive/frame reversal drive (selected by a command)

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

? A variety of commands

Read/write of display data, display ON/OFF, normal/reverse display, all dots ON/all dots OFF, set page address, set display start address, etc.

? Power supply voltage

Logic power supply: VDD-VSS = 1.8 V to 5.5 V

Voltage multiplier reference voltage: VIN-VSS = 1.8 V to VDD (5-Times multiplier fi 1.8 V to 3.6 V, 6-times multiplier fi 1.8 to 3 V, 7-times multiplier fi 1.8 to 2.5 V)

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