In addition to generating dot matrix LCD drive signals based on data transferred serially from a microcontroller, the LC75810E and LC75810T 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 80 segments) • Display technique: 1/8-duty, 1/4-bias drive (5 × 7 dots, 6 × 7 dots) 1/9-duty, 1/4-bias drive (5 × 8 dots, 6 × 8 dots) 1/10-duty, 1/4-bias drive (5 × 9 dots, 6 × 9 dots) • Display digits: 16 digits × 1 line (5 × 7 dots), 15 digits × 1 line (5 × 8 or 5 × 9 dots) 13 digits × 1 line (6 × 7, 6 × 8, or 6 × 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) DCRAM: 64 × 8 bits ALATCH: 80 bits • Instruction function Display on/off control Smooth up, down, left, and right scrolling of the display • Provides a backup function based on power saving mode • The frame frequency of the common and segment output waveforms can be controlled by instructions. • Built-in display contrast adjustment circuit • Serial data input supports CCB format communication with the system controller • Independent LCD driver block power supply VLCD • Provides a RES pin for IC internal initialization. • RC oscillator circuit CMOS IC 1/8 to 1/10 Duty Dot Matrix LCD Display Controllers/Drivers Ordering number : ENN7141 • CCB is ON Semiconductor® ’s original format. All addresses are managed by ON Semiconductor® for this format. • CCB is a registered trademark of Semiconductor Components Industries, LLC.
