LC75808E, 75808W
1/8 to 1/10 Duty LCD Display Drivers
with Key Input Function
Overview
The LC75808E and LC75808W are 1/8 to 1/10 duty LCD
display drivers that can directly drive up to 600 segments
and can control up to four general-purpose output ports.
These products also incorporate 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.
