Sanyo LC75827E
Ordering number : ENN7665
CMOS LSI
LC75827E, 75827W
1/3, 1/4 Duty General-Purpose LCD Driver
Overview
The LC75827E and LC75827W are 1/3, 1/4 duty general-
purpose LCD drivers that can be used for frequency
display in electronic tuners under the control of a
microcontroller. In addition to being able to directly drive
up to 200 LCD segments, the LC75827E and LC75827W
can also control up to 12 general-purpose output ports.
The LC75827E/W uses separate power supplies for the
LCD driver block and the logic block. This allows the
LCD driver block supply voltage to be set to any level in
the 2.7 to 6.0 V range independently of the logic block
supply voltage.
Features
• Either 1/3 or 1/4 duty can be selected with the serial
control data.
• Either 1/2 or 1/3 bias can be selected with the serial
control data.
• Up to 153 segments can be driven in 1/3 duty drive and
up to 200 segments can be driven in 1/4 duty drive.
• 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 general-purpose output port functions
• The frame frequency of the common and segment output
waveforms can be controlled with the serial control data.
• Either RC oscillation or external clock mode can be
selected with the serial control data.
• 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.
• CCB is a trademark of SANYO ELECTRIC CO., LTD.
• CCB is SANYO’s original bus format and all the bus
addresses are controlled by SANYO.
Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other
parameters) listed in products specifications of any and all SANYO products described or contained
