LC75808W
CMOS IC
1/8 to 1/10 Duty
LCD Display Driver
with Key Input Function
http://onsemi.com
Overview
The LC75808W is 1/8 to 1/10 duty LCD display driver that can directly drive up to 600 segments and can control up
to four general-purpose output ports. This product also incorporates a key scan circuit that accepts input from up to 30
keys to reduce printed circuit board wiring.
Features
• Key input function for up to 30 keys (A key scan is performed only when a key is pressed.)
• 1/8duty–1/4bias, 1/9duty–1/4bias, and 1/10duty–1/4bias drive schemes can be controlled from serial data.
1/8duty–1/4bias: up to 480 segments
1/9duty–1/4bias: up to 540 segments
1/10duty–1/4bias: up to 600 segments
• Sleep mode and all segments off functions that are controlled from serial data.
• Serial data I/O supports CCB format communication with the system controller.
• Direct display of display data without the use of a decoder provides high generality.
• Built-in display contrast adjustment circuit.
• Up to 4 general-purpose output ports are included.
• Independent LCD driver block power supply VLCD.
• Provision of an on-chip voltage-detection type reset circuit prevents incorrect displays.
• The INH pin is provided. This pin turns off the display, disables key scanning, and forces the general-purpose
output ports to the low level.
• RC oscillator circuit.
• 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.
