LC75834E, 75834W, 75834JE
1/4 Duty General-Purpose
LCD Drivers
Overview
The LC75834E, LC75834W, and LC75834JE are 1/4-duty
general-purpose LCD drivers that can be used for
frequency display in electronic tuners under the control of
a microcontroller. The LC75834E and LC75834W can
drive an LCD with up to 136 segments directly, the
LC75834JE can drive an LCD with up to 120 segments
directly. The LC75834E and LC75834W and LC75834JE
can also control up to 8 general-purpose output ports.
Since the LC75834E, LC75834W, and LC75834JE use
separate power supply systems for the LCD drive block
and the logic block, the LCD driver block power-supply
voltage can be set to any voltage in the range 2.7 to 6.0
volts, regardless of the logic block power-supply voltage.
Features
• Supports both 1/4 duty 1/2 bias and 1/4 duty 1/3 bias
LCD drive under serial data control.
LC75834E, LC75834W: up to 136 segments
LC75834JE:
up to 120 segments
(without the S9, S18, S27, S34 segment output pins
from the LC75834E, LC75834W)
• 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
• Serial data control of switching between the segment
output port and the general-purpose output port
functions
• High generality, since display data is displayed directly
without decoder intervention.
• Independent VLCD for the LCD driver block (VLCD can
be set to any voltage in the range 2.7 to 6.0 volts,
regardless of the logic block power-supply voltage.)
• The INH pin can force the display to the off state.
• RC oscillator circuit

Note: This applies to the case where the S1/P1 to S8/P8 output pins are set to be segment output ports.
The LC75834JE do not have the S9, S18, S27, S34 output pins.
For example, the table below lists the segment output states for the S11 output pin.
