DESCRIPTION
The PT6586 is 1/4 duty general-purpose LCD driver
that can be used for frequency display in electronic
tuners under the control of a microcontroller. The
PT6586 can drive an LCD with up to 140 segments
directly. The PT6586 can also control up to 4
general-purpose output ports.
APPLICATION
• Electronic equipment with LCD Display

LCD Control/Driver IC
FEATURES
• Up to 140 segments for 1/4 duty drive can be
displayed
• Serial interface for clock, Data Input, Strobe pins
• 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
• Serial data control of frame frequency for common
and segment output waveforms
• High generality, since display data is displayed
directly without decoder intervention
• The INHB pin can force the display to the off state
• RC oscillator circuit

Function
Segment outputs for displaying the display data
transferred by serial data input. The pins
SEG1/GP1 to SEG4/GP4 can be used as
general-purpose output ports when so set up by
the control data.
Common driver outputs.
The frame frequency is fO Hz.
Logic block power supply. Provide a voltage in
the range 4.5 to 6.0V.
LCD drive 2/3 bias voltage (middle level) supply.
It is possible to supply the 2/3 VDD voltage to
this pin externally.
LCD drive 1/3 bias voltage (middle level) supply.
It is possible to supply the 1/3 VDD voltage to
this pin externally.
Ground pin. Connect to ground.
Oscillator connection.
An oscillator circuit is formed by connecting an
external resistor and capacitor to this pin.
Display off control input
• INHB = low (VSS)…off
SEG1/ GP1 to SEG4/GP4 = low (VSS)
(These pins are forcibly set to the
segment output port function and fixed at
the VSS level)
SEG5 to SEG35 = low (VSS)
COM1 to COM4 = low (VSS)
• INHB = high (VDD)…on
Note that serial data transfers can be performed
when the display is forced off by this pin.
Serial data transfer inputs. These pins are
connected to the control microprocessor.
