CMOS IC  
LC73101C  
LCD Driver IC  
Preliminary  
Overview  
The LC73101C is a dot matrix LCD driver IC that  
includes an on-chip display data RAM with a one-to-one  
correspondence between bits in RAM and display pixels  
on the LCD panel. The LC73101C provides display data  
RAM that can store 80 × 132 bits of data and can  
implement a large-screen display system with a single  
chip.  
power supply voltage adjustment, temperature-  
compensated reference voltage, and display contrast  
adjustment electronic potentiometers circuits, the  
LC73101C can implement portable display systems with  
low power consumption and a minimal number of external  
components.  
Features  
• 132 × 80-dot display  
• Microcontroller interface (for both Intel and Motorola  
microcontrollers)  
• On-chip display RAM (80 × 132 = 10,560 bits)  
• Low power  
The LC73101C provides 80 common output circuits and  
132 segment output circuits, and can display up to 80 ×  
132 dots (8 characters × 4 lines of kanji text using a 16 ×  
16-dot kanji font) with a single chip. The LC73101C also  
provides a master/slave function that allows two  
LC73101C chips to be combined to implement twice the  
display area: 160 × 132 dots.  
• Low-voltage operation: V = 1.8 to 3.6 V  
DD  
• High-precision reference voltage circuit (Variable  
temperature compensation coefficients)  
• LCD drive 6× voltage step-up circuit (3×, 4×, 5×, or 6×  
can be selected by commands from the microcontroller.)  
• Built-in high-precision RC oscillator circuit  
• Contrast adjustment electronic potentiometer circuit  
• Partial display function (Allows 8, 16, 24, 32, 40, 48,  
56, 64, 72, or 80 lines to be displayed under the control  
of commands sent from the microcontroller.)  
The LC73101C provides a partial display function that  
allows the number of lines displayed to be set to 8, 16, 24,  
32, 40, 48, 56, 64, 72, or 80 lines by commands sent from  
the system microcontroller. This allows the current drain  
to be reduced significantly when only a smaller number of  
lines needs to be displayed.  
• Supports synchronous operation using master/slave  
connection.  
This device includes built-in voltage step-up circuits with  
factors of 3×, 4×, 5×, and 6× to provide high-quality  
display even when a high duty cycle is required. The  
number of step-up circuit stages used can be set by  
commands from the system microcontroller.  
Since the display RAM read and write operations do not  
require the external operating clock, the LC73101C can  
operate at low power. Furthermore, since the LC73101C  
provides built-in LCD drive power supply, LCD drive
