Overview
The LC75804E and LC75804W are 1/3 duty and 1/4 duty
LCD display drivers that can directly drive up to 300
segments and can control up to eight 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.)
1/3 duty and 1/4 duty drive schemes can be controlled
from serial data.
1/2 bias and 1/3 bias drive schemes can be controlled
from serial data.
Capable of driving up to 228 segments using 1/3 duty
and up to 300 segments using 1/4 duty.
Sleep mode and all segments off functions that are
controlled from serial data.
Segment output port/general-purpose output port
function switching that is 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.
Independent V
LCD
for the LCD driver block (V
LCD
can
be set to in the range V
DD
0.5 to 6.0 volts.)
Provision of an on-chip voltage-detection type reset
circuit prevents incorrect displays.
RES pin provided for forcibly initializing the IC internal
circuits.
RC oscillator circuit.
