Overview
The LC75838W is 1/8 to 1/10 duty general-purpose LCD display driver used
for character and graphics display. This product operates under the control of a
microcontroller and can directly drive an LCD with up to 380 segments. It can
also control up to 3 general-purpose output ports.
SPQFP64 10x10 / SQFP64
Features
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 320 segments
1/9duty–1/4bias: up to 351 segments
1/10duty–1/4bias: up to 380 segments
Serial data input supports CCB format communication with the system controller.
Serial data control of the power-saving mode based backup function and all the segments forced off function.
Direct display of display data without the use of a decoder provides high generality.
Built-in display contrast adjustment circuit.
Up to 3 general-purpose output ports are included.
Independent LCD driver block power supply VLCD.
The INH pin is provided. This pin turns off the display 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.
