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.
