Overview
The LC75844M is a 1/4 duty general-purpose LCD driver
that can be used for frequency display in electronic tuners
under the control of a microcontroller. The LC75844M
can drive an LCD with up to 88 segments directly. The
LC75844M can also control up to 4 general-purpose
output ports. Since the LC75844M uses 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
• Support for 1/4 duty 1/2 bias or 1/4 duty 1/3 bias drive
of up to 88 segments under serial data control.
• 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 V
LCD
for the LCD driver block (V
LCD
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

Serial Data Transfer Examples

• When fewer than 45 segments are used, only 56 bits of serial data need to be sent. However, the display data D1 to D44
and the control data must be sent.

Control Data Functions
1. P0 to P2: Segment output port/general-purpose output port switching control data.
These control data bits switch the S1/P1 to S4/P4 output pins between their segment output port and general-purpose
output port functions.
Note: Sn (n = 1 to 4): Segment output ports
Pn (n = 1 to 4): General-purpose output ports
Also note that when the general-purpose output port function is selected, the output pins and the display data will
have the correspondences listed in the tables below.
For example, if the output pin S4/P4 has the general-purpose output port function selected, it will output a high level
(V
LCD
) when the display data D13 is 1, and will output a low level (VSS) when D13 is 0.
2. DR: 1/2 bias drive or 1/3 bias drive switching control data
This control data bit selects either 1/2 bias drive or 1/3 bias drive.
3. SC: Segments on/off control data
This control data bit controls the on/off state of the segments.
However, note that when the segments are turned off by setting SC to 1, the segments are turned off by outputting
segment off waveforms from the segment output pins.
4. BU: Normal mode/power-saving mode control data
This control data bit selects either normal mode or power-saving mode.

The INH pin and Display Control
Since the IC internal data (the display data and the control data) is undefined when power is first applied, applications
should set the INH pin low at the same time as power is applied to turn off the display (This sets the S1/P1 to S4/P4, S5
to S22, and COM1 to COM4 to the VSSlevel.) and during this period send serial data from the controller. The controller
should then set the INH pin high after the data transfer has completed. This procedure prevents meaningless displays at
power on. (See Figure 3.)
Notes on the Power On/Off Sequences
Applications should observe the following sequence when turning the LC75844M power on and off.
• At power on: Logic block power supply (VDD) on → LCD driver block power supply (V
LCD
) on
• At power off: LCD driver block power supply (V
LCD
) off → Logic block power supply (VDD) off
However, if the logic and LCD driver block use a shared power supply, then the power supplies can be turned on and off
at the same time.

Notes on Controller Transfer of Display Data
Since the LC75844M accept display data (D1 to D88) divided into two separate transfer operations, we recommend that
applications transfer all of the display data within a period of less than 30 ms to prevent observable degradation of
display quality.
