LC75836WS-T
CMOS LSI
1/4-Duty
General-Purpose LCD Driver
Overview
The LC75836WS-T is 1/4-duty general-purpose microprocessor-
controlled LCD driver that can be used in applications such as
frequency display in products with electronic tuning. In addition to
being able to drive up to 140 segments directly, the LC75836WS-T
can also control up to 4 general-purpose output ports.

Features
1/4 duty, 1/3 bias drive (Up to 140 segment can be displayed.)
Serial data input supports CCB* format communication with the system controller (support 3V operation).
Serial data control of the power-saving mode based backup function and the all segments forced off function.
Serial data control of switching between the segment output port and general-purpose output port functions.
Serial data control of the frame frequency of the common and segment output waveforms.
Either RC oscillator operating or external clock operating mode can be selected with the serial control data.
High generality, since display data is displayed directly without the intervention of a decoder circuit.
The INH pin allows the display to be forced to the off state.
RC oscillation circuit (with external resistor and capacitor)
CCB is ON Semiconductor® ’s original format. All addresses are managed
by ON Semiconductor® for this format.

5. BU: Normal mode/power-saving mode control data
This control data bit selects either normal mode or power saving mode.
BU Mode
0 Normal mode
Power saving mode.
In RC oscillator operating mode (OC = 0), the OSC pin oscillator is stopped, and in external clock operating mode
1 (OC = 1), acceptance of the external clock is stopped. In this mode the common and segment output pins go to the
VSS levels. However, S1/P1 to S4/P4 output pins that are set to be general-purpose output ports by the control data
P0 to P2 can be used as general-purpose output ports.
