40-DOT SEGMENT DRIVER
GENERAL DESCRIPTION
The MSM5839B is a dot matrix LCD segment driver LSI which is fabricated using low power
CMOS metal gate technology. This LSI consists of two 20-bit shift registers, two 20-bit latches,
a 40-bit level shifter and a 40-bit 4-level driver.
It converts serial data, which is received from an LCD controller LSI, to parallel data and outputs
LCD driving waveform to the LCD panel.
Expansion of display can easily be made by increasing the number of characters and character
patterns.
This LSI can drive a variety of LCD panels because the bias voltage, which determines the LCD
driving voltage, can be optionally supplied from the external source.
FEATURES

FUNCTIONAL DESCRIPTION
Pin Functional Description
• DI1
The data input pin for the 20-bit shift register (from 1st to 20th bit). The display data is input
to the data pin in synchronization with a clock pulse.
• CP
Clock pulse input pin for the two 20-bit shift registers. The data is shifted in the two 20-bit shift
registers at the falling edge of the clock pulse. Data setup time (tSETUP) and data hold time
(tHOLD) are required each between DI1, DI21 and CP. Refer to the Switching Characteristics.
• DO20
The 20th output bit of the shift register.
The data which is input from DI1 is clocked out with the delay in the number of bits of the shift
register (20). A 40-bit shift register can be configured by connecting the output of this pin to
DI21 pin.
• DI21
The data input pin for the 20-bit shift register (from 21st to 40th bit).
Connecting the DO20 pin and this pin allows the device to be used as a 40-bit shift register.
• DO40
The 40th output bit of the shift register.
The data which is input from DI1 is clocked out with the delay in the number of the bits of the
shift register (20).
When extending the number of characters, this pin is used to cascade connect the next
MSM5839B.
• DF
Alternate signal input pin for LCD driving waveform.
• VDD(V1), VSS
Supply voltage pins. VDD should be 4.5 to 5.5V.
VSS is the ground pin (VSS = 0V).
• V2, V3, VEE(V4)
Bias supply voltage pins to drive the LCD. Bias voltage is supplied from an external source.
• LOAD
The signal for latching the shift register contents is input from this pin.
When LOAD pin is set at "H", the shift register contents are transferred to the 40-bit 4-level
driver. When LOAD pin is set at "L", the last display output data (O1 to O40), which was
transferred when LOAD pin was at "H", is held.

• O1 to O40
Display data output pins which correspond to each data bit in the latch.
One of VDD, V2, V3 or VEE (V4) is selected as a display driving voltage source based on the
combination of latched data level and DF signal. Refer to the Truth Table below.
These pins should be connected to the SEGMENT side of the LCD panel.

Notes for Mounting the Surface Mount Type Package
The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which
are very susceptible to heat in reflow mounting and humidity absorbed in storage.
Therefore, before you perform reflow mounting, contact Oki’s responsible sales person for the
product name, package name, pin number, package code and desired mounting conditions
(reflow method, temperature and times).
