LC75893M
1/3 Duty LCD Display Driver with Key Input Function
Overview
The LC75893M is a 1/3 duty LCD display driver that can
directly drive up to 48 segments and can control up to four
general-purpose output ports. This product also
incorporates a key scan circuit that accepts input from up
to 20 keys to reduce printed circuit board wiring.
Features
• Key input function for up to 20 keys (A key scan is
performed only when a key is pressed.)
• 1/3 duty - 1/2 bias and 1/3 duty - 1/3 bias drive schemes
can be controlled from serial data (up to 48 segments).
• Sleep mode and all segments off functions that are
controlled from serial data
• Segment output port/general-purpose output port
function switching that is controlled from serial data
• Serial data I/O supports CCB format communication
with the system controller.
• Direct display of display data without the use of a
decoder provides high generality.
• Provision of an on-chip voltage-detection type reset
circuit prevents incorrect displays.
• RC oscillator circuit

Function
Segment outputs for displaying the display data transferred by serial data
input.
The S1/P1 to S4/P4 pins can be used as general-purpose output ports
under serial data control.
Common driver outputs
The frame frequency fO is given by: fO = (fOSC/384) Hz.

these outputs are used to form a key matrix. The KS1/S15 and KS2/S16
pins can be used as segment outputs when so specified by the control data.

Oscillator connection
An oscillator circuit is formed by connecting an external resistor and
capacitor at this pin.
Serial data interface connections to the controller. Note that DO, being an
open-drain output, requires a pull-up resistor.

This pin must be connected to ground.
Used for applying the LCD drive 2/3 bias voltage externally. Must be
connected to VDD2 when a 1/2 bias drive scheme is used.
Used for applying the LCD drive 1/3 bias voltage externally. Must be
connected to VDD1 when a 1/2 bias drive scheme is used.
