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
• Package: Gold bump chip, TCP
