I/O
PPoowweerr  SSuuppppllyy  ffoorr  OOppeerraattiioonn  
This  is  a  voltage  supply  pin.    It  must  be  connected  to
external source & always be equal to or higher than VDD
& VDDIO. 
PPoowweerr  SSuuppppllyy  ffoorr  CCoorree  LLooggiicc  CCiirrccuuiitt  
This is a voltage supply pin which is regulated internally
from  VCI.    A  capacitor  should  be  connected  between
this pin & VSS under all circumstances. 
PPoowweerr  SSuuppppllyy  ffoorr  II//OO  PPiinn  
This pin is a power supply pin of I/O buffer.    It should
be connected to VCI or external source.    All I/O signal
should have VIH reference to VDDIO.    When I/O signal
pins  (BS0~BS1,  D0~D7,  control  signals…)  pull  high,
they should be connected to VDDIO. 
GGrroouunndd  ooff  OOEELL  SSyysstteemm  
This is a ground pin.    It also acts as a reference for the
logic  pins,  the  OEL  driving  voltages,  and  the  analog
circuits.    It must be connected to external ground. 
PPoowweerr  SSuuppppllyy  ffoorr  OOEELL  PPaanneell  
This is the most positive voltage supply pin of the chip.
It must be connected to external source. 
CCuurrrreenntt  RReeffeerreennccee  ffoorr  BBrriigghhttnneessss  AAddjjuussttmmeenntt  
This  pin  is  segment current  reference  pin.    A  resistor
should be connected between this pin and VSS.    Set the
current lower than 12.5uA. 
VVoollttaaggee  OOuuttppuutt  HHiigghh  LLeevveell  ffoorr  CCOOMM  SSiiggnnaall 
This pin is the input pin for the voltage output high level
for  COM  signals.    A  tantalum  capacitor  should  be
connected between this pin and VSS. 
VVoollttaaggee  OOuuttppuutt  LLooww  LLeevveell  ffoorr  SSEEGG  SSiiggnnaall 
This is segment voltage reference pin. 
When  external  VSL  is  not  used,  this  pin  should  be  left
open. 
When external VSL is used, this pin should connect with
resistor and diode to ground. 
GGeenneerraall  PPuurrppoossee  IInnppuutt//OOuuttppuutt  
These pins could be left open individually or have signal
inputted/outputted.    They are able to use as the external
DC/DC converter circuit enabled/disabled control or other
applications.

PPoowweerr  RReesseett  ffoorr  CCoonnttrroolllleerr  aanndd  DDrriivveerr  
This  pin  is  reset  signal  input.    When  the  pin  is  low,
initialization of the chip is executed. 
CChhiipp  SSeelleecctt  
This pin is the chip select input.    The chip is enabled for
MCU communication only when CS# is pulled low. 
DDaattaa//CCoommmmaanndd  CCoonnttrrooll  
This pin is Data/Command control pin.    When the pin is
pulled high, the input at D7~D0 is treated as display data.
When the pin is pulled low, the input at D7~D0 will be
transferred 
  For  detail
relationship to MCU interface signals, please refer to the
Timing Characteristics Diagrams. 
When  3-wire  serial  mode  is  selected,  this  pin  must be
connected to VSS. 
RReeaadd//WWrriittee  EEnnaabbllee  oorr  RReeaadd  
This pin is MCU interface input.    When interfacing to a
68XX-series microprocessor, this pin will be used as the
Enable (E) signal. Read/write operation is initiated when
this pin is pulled high and the CS# is pulled low. 
When  connecting  to  an  80XX-microprocessor,  this  pin
receives the Read (RD#) signal.    Data read operation is
initiated  when  this  pin  is  pulled  low  and  CS#  is  pulled
low. 
When serial mode is selected, this pin must be connected
to VSS.  
RReeaadd//WWrriittee  SSeelleecctt  oorr  WWrriittee  
This pin is MCU interface input.    When interfacing to a
68XX-series  microprocessor,  this  pin  will  be  used  as
Read/Write  (R/W#)  selection  input.    Pull  this  pin  to
“High”  for  read  mode  and  pull  it  to  “Low”  for  write
mode. 
When  80XX  interface  mode  is  selected,  this  pin  will be
the Write (WR#) input.    Data write operation is initiated
when this pin is pulled low and the CS# is pulled low. 
When serial mode is selected, this pin must be connected
to VSS. 
HHoosstt  DDaattaa  IInnppuutt//OOuuttppuutt  BBuuss  
These  pins  are  8-bit  bi-directional  data  bus  to  be
connected to the microprocessor’s data bus.    When serial
mode  is  selected, D1 will  be  the  serial  data  input  SDIN
and D0 will be the serial clock input SCLK. 
Unused pins must be connected to VSS except for D2.
