MSM5259
40-DOT SEGMENT DRIVER
This version: Nov. 1997
MSM5259
Previous version: Mar. 1996
GENERAL DESCRIPTION
The MSM5259 is a dot matrix LCD segment driver which is fabricated using low power CMOS
metal gate technology. This LSI consists of 40-bit shift register, 40-bit latch and 40-bit 4-level
driver.
It converts serial data, which is received from an LCD controller LSI, to parallel data and outputs
LCD driving waveforms to LCD.
Expansion of the display can be easily made according to the number and structure of characters.
Since the 40-bit shift register of this device consists of two 20-bit shift registers, it is possible to
allot bits efficiently according to the number of characters.
The MSM5259 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. For static operation
only, the device is available with a power supply voltage of 2.5V or more.

56-Pin Plastic QFP (Type L)
*
Do not connect pin 21 to the other signal pins, because the pin is internally connected to V
DD
.
Do not use pin 21 as a single V
DD
signal line. It is permissible to use pin 21 for supplying a
higher power of V
DD
.
Note : The figure for Type L shows the configuration viewed from the reverse side of the package.
Pay attention to the difference in pin arrangement.
