CMOS IC
LC75811E, 75811W
1/8 to 1/10 Duty Dot Matrix LCD Display Controller/Driver
Overview
The LC75811E and LC75811W are 1/8 to 1/10 duty dot
matrix LCD display controller/drivers that supports the
display of characters, numbers, and symbols. In addition to
generating dot matrix LCD drive signals based on data
transferred serially from a microcontroller, the LC75811E
and LC75811W also provide on-chip character display ROM
and RAM to allow display systems to be implemented easily.
Features
• Controls and drives a 5 × 7, 5 × 8, or 5 × 9 dot matrix LCD.
• Supports accessory display segment drive (up to 60
segments)
• Display technique: 1/8 duty 1/4 bias drive (5 × 7 dots)
1/9 duty 1/4 bias drive (5 × 8 dots)
1/10 duty 1/4 bias drive (5 × 9 dots)
• Display digits: 12 digits × 1 line (5 × 7 dots),
11 digits × 1 line (5 × 8 or 5 × 9 dots)
• Display control memory
CGROM: 240 characters (5 × 7, 5 × 8, or 5 × 9 dots)
CGRAM: 16 characters (5 × 7, 5 × 8, or 5 × 9 dots)
ADRAM: 12 × 5 bits
DCRAM: 48 × 8 bits
• Instruction function
Display on/off control
Display shift function
• Provides a backup function based on low power modes.
• Serial data input supports CCB format communication
with the system controller.
• Independent LCD drive block power supply VLCD
• Provides a RES pin for LSI internal initialization
• RC oscillator circuit
