LC75833E, 75833W, 75833JE
1/3 Duty General-Purpose
LCD Display Drivers
Overview
The LC75833E, LC75833W, and LC75833JE are 1/3-duty
general-purpose LCD display drivers that can be used for
frequency display in electronic tuners under the control of
a microcontroller. The LC75833E and LC75833W can
drive an LCD with up to 105 segments directly, the
LC75833JE can drive an LCD with up to 93 segments
directly. The LC75833E and LC75833W and LC75833JE
can also control up to 8 general-purpose output ports.
Since the LC75833E, LC75833W, and LC75833JE 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 1/3 duty 1/2 bias and 1/3 duty 1/3 bias
LCD drive under serial data control.
LC75833E, LC75833W: up to 105 segments
LC75833JE:
up to 93 segments
(without the S12, S23, S24, S35 segment output pins
from the LC75833E, LC75833W)
• 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
