Dear customer  
LAPIS Semiconductor Co., Ltd. ("LAPIS Semiconductor"), on the 1st day of October,  
2020, implemented the incorporation-type company split (shinsetsu-bunkatsu) in which  
LAPIS established a new company, LAPIS Technology Co., Ltd. (“LAPIS  
Technology”) and LAPIS Technology succeeded LAPIS Semiconductor’s LSI business.  
Therefore, all references to "LAPIS Semiconductor Co., Ltd.", "LAPIS Semiconductor"  
and/or "LAPIS" in this document shall be replaced with "LAPIS Technology Co., Ltd."  
Furthermore, there are no changes to the documents relating to our products other than  
the company name, the company trademark, logo, etc.  
Thank you for your understanding.

PIN DESCRIPTION  
Symbol  
I/O  
Description  
Pin for oscillation. Has a Schmitt circuit built in.  
An oscillator circuit can be configured by connecting one external resistor and one  
external capacitor.  
Since an oscillator circuit is susceptible to external noise, make the wiring  
between this pin and external components as short as possible. An external clock  
input can be selected by CLKSEL.  
OSC  
I/O  
The relationship between oscillation frequency fOSC and frame frequency fFRM is:  
f
FRM = fOSC/24(*1)  
Serial data input pin. Has a Schmitt circuit built in.  
The LCD display is turned on when the input data signal is at a “H” level and  
turned off when the input data signal is at a “L” level.  
Shift clock input pin. Has a Schmitt circuit built in.  
Data to the DATA_IN pin is shifted in sync with the rising edges of the shift clock  
pulses.  
DATA_IN  
CLOCK  
I
I
Load pulse input pin. Has a Schmitt circuit built in.  
Used to transfer serially input data to the display latch or write commands.  
IC test pin. Has a pull-down resistor built in.  
Leave this pin open or connect it to VSS when not used.  
OSC pin input switching pin.  
LOAD  
TEST  
I

When using the built-in oscillator circuit, set this pin to a “L” level; when inputting  
an external clock, set this pin to a “H” level. While this pin is at a “H” level, the  
oscillator circuit connected is disabled.

I
1/3- or 1/4-duty switching input pin. When “H” level is input, 1/3 duty is selected  
and when “L” level is input, 1/4 duty is selected.  
Reset signal input pin for initializing the IC. Has a Schmitt circuit built in.  
This pin is enabled by setting it to “L” level. This pin has a built-in pull-up resistor.  
Normally, this pin, when connected with an external capacitor, performs power-on  
reset.(*2)  
Output pins for LCD display. Connect to the common pins of the LCD panel.  
- When 1/3 duty is selected:  
Common signals are outputted through the COM1, COM2, and COM3 pins.  
Leave the COM4 pin open.  
- When 1/4 duty is selected:  
Common signals are outputted through the COM1, COM2, COM3, and COM4  
pins.

If LVDD is in the range of 0 V to LVDDmin, make sure that LVDD DVDD and t 0[ns] are satisfied.  
When performing power-on reset with a capacitor connected to the RESET pin, be careful about the relationship  
between the capacitance value and the rise time of the power supply.

t1  
Drive the RESET pin Low and hold it Low under the condition “t1 0[ns]” until LVDD reaches LVDDmin.  
The value of the current of the pull-up resistor is specified for RESET pin.  
The customer needs to select an external capacitor that meets the timing requirements shown above.

Description of Operation  
Display data input  
As described in the section on “Data Structure,” display data consists of a data field, which corresponds to the  
LCD segments ON and OFF, and a command field, which indicates the input of display data.  
Set a value in each of bits C0 and C1 in the command field according to the common output that corresponds to  
the display data, and set a display data input command in the remaining four bits.  
Data that has been input to the DATA_IN pin is loaded into the shift register on the rising edges of the CLOCK  
pulses, transferrred to the display data latch during the “H” level period of the LOAD pulse, and then output via  
the segment driver.

Display ON, display OFF  
Display goes off when power-on reset is executed; therefore, to turn display on, write the display ON command  
(F5).  
The display OFF command (F4) is a command that makes all segments go off. By writing the display OFF  
command, the segments go off irrespective of display data.  
The display ON command (F5) is a command that clears a display off state. By writing the display ON command,  
display goes back to the previous state.

If a “Disabled” command is executed, no transfer is carried out from the shift register to the latch; however, data  
within the shift register will be rewritten. To transfer correct data to the latch, it is necessary to transfer data  
again using the F1 command.

Command  
Note 1: The setting of command F4 or F5 becomes enabled by inputting only the four bits of C2 to C5.  
(No need to input D1 to D32, C0, or C1.)  
Note 2: If any dummy bits are required because of the transfer bit count, add them before the first bit.  
Note 3: Command execution depends on the value of bits C5 to C0 stored immediately before LOAD goes to a  
“H” level.

Notes for Mounting the Surface Mount Type Package  
The surface mount type packages are very susceptible to heat in reflow mounting and humidity absorbed in  
storage. Therefore, before you perform reflow mounting, contact ROHM's responsible sales person for the  
product name, package name, pin number, package code and desired mounting conditions (reflow method,  
temperature and times).
