PT16588
1/8, 1/15 DUTY LCD Controller/Driver
DESCRIPTION
The PT16588 is a controller/driver with 1/8 and 1/15 duty dot
matrix LCD display capability. It has 60 segment outputs, 10
common outputs, and 5 dual segment/common outputs,
giving a maximum display capability of 12 columns x 2 lines
(at 1/15 duty).
LED drive outputs, key scanning key source outputs, and key
data inputs are also provided, making it ideal for use in a car
stereo front panel, etc.
FEATURES
 Dot matrix LCD controller/driver
 Pictograph display segment drive capability (MAX.
64)
 LCD driver unit power supply VLCD independently
settable (MAX. 10 V)
 On-chip key scan circuit (8 × 4 matrix)
 Alphanumeric character and symbol display
capability provided by on-chip ROM (5 × 7 dots)
 240 characters + 16 user-defined characters
 Display contents
- 1/8 duty: 13 columns × 1 line, 64 pictograph
displays, 4 LEDs
- 1/15 duty: 12 columns × 2 lines, 60 pictograph
displays, 4 LEDs
 Serial data input/output (SCK, /STB, DATA)
 On-chip oscillator
 Reduced power consumption possible using
standby mode

Description
LED outputs are Nch open-drain
GND pin
Dot matrix LCD drive power supply. Connect
VLC5 to ground when an internal oscillator is
used.
LCD drive power supply pin
Internal logic power supply pin
Synchronization signal input/output pin.
When 2 or more chips are used, wired-OR
connection is made to each chip. A pull-up
resistor is also required when one chip is
used.
When “L”, a forced LCD off operation is
performed, and SEGn & COMn output the
unselected waveform.
Initial state is set when “L”.
“H” if there is key data, “L” if there is none.
Key data can be read irrespective of the
state of this pin. Output is CMOS output.
Data shift clock.
Data is read on rising edge, and output on
falling edge.
Performs input of commands, key data, etc.,
and key data output. Input is performed from
the MSB on the rise of the shift clock, and the
first 8 bits are recognized as a command.
Output is performed from the MSB on the fall
of the shift clock. Output is Nch open-drain.
Data input is enabled when “H”. Command
processing is performed on a fall.
Connect oscillator resistor.
When an external oscillator is used, input a
clock signal to the OSCIN pin and leave
OSCOUT pin open.
