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.

POWER ON/OFF TIMING
To turn on the power supply, raise the logic power supply first, then LCD drive power supply in order to prevent
the IC from malfunctioning.
To fall the power supply, fall the LCD drive power supply first, then the logic power supply.
For a VDD pin ranging from 0 V to VDDmin, set VDD ≥ VLCD and t1 ≥ 0 [ns].

DESCRIPTION
Operation description
• Display data input
As described in the Data configuration section, the display data consists of the data field that corresponds to
each segment on/off and the command field that indicates the display data input.
When inputting the display data, the "F1" command is set in the command field. When the "F2" to "F5"
command is set in the command field, the display data in the data field becomes invalid.
The data input to the DATA pin is loaded to the shift register at the CLOCK pulse rise, transferred to the
display data latch during the LOAD pulse at the "H" level, then output via the segment driver.

• Display on, Display off
The display becomes off at power-on reset. To display, write the display on command.
The display off is the command that makes all segments off. Writing the display off command turns off the
lights regardless of the display data.
The display on is the command to release the display off. Writing the display on command returns the display
to the original state.

Note 1: The commands F4 settings become valid when the least four bits of C2 to C5 are input.
(The bits from D1 to D50 and from C0 to C1 are not necessary.)
The commands F3 and F4 settings become valid when the least five bits of C1 to C5 are input.
(The bits from D1 to D50 and from C0 are not necessary.)
The commands F2 settings become valid when the least six bits of C0 to C5 are input.
(The bits from D1 to D50 are not necessary.)
Note 2: If the dummy bit is needed for the reason of number of transfer bits, put it on the first bit side.
Note 3: The command execution follows the contents of the C5 to C0 registers immediately before the LOAD
becomes "H".

TEST
REFRESH
Although the ML9484 holds operation state by commands, excessive external noise might change the
internal state.
On a chip-mounting and system level, it is necessary to take countermeasures against preventing noise from
occurring. It is recommended to use the refresh sequence periodically to control sudden noise.

PACKAGE DIMENSIONS
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).
