Overview
The LC75841PE is static drive or 1/2-duty drive, microcontroller-controlled general-purpose LCD driver that can be
used in applications such as frequency display in products with electronic tuning. In addition to being capable to drive
up to 54 segments directly, it can control up to 4 general-purpose output ports.
Features
Serial data control of switching between static drive mode and 1/2 duty drive mode.
When 1/1-duty: Capable of driving up to 27 segments
When 1/2-duty: Capable of driving up to 54 segments
Serial data input supports CCB format communication with the system controller.
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
(up to 4 general-purpose output ports).
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.
Allows compatible operation with the LC75842 (842 mode transfer function).
CCB is ON Semiconductor® ’s original format. All addresses are managed
by ON Semiconductor® for this format.
CCB is a registered trademark of Semiconductor Components Industries, LLC.

Display off control input
• INH = low (VSS) ...Display forced off
S1/P1 to S4/P4 = low (VSS)
(These pins are forcibly set to the segment output port function
and held at the VSS level.)
S5 to S27 = low (VSS)

OSC = Z (high impedance)
L
RC oscillation stopped
Inhibits external clock input.
• INH = high (VDD)...Display on
RC oscillation enabled (RC oscillator operating mode)
Enables external clock input (external clock operating mode)
However, serial data transfer is possible when the display is forced off.
