Select bits C1 to C4 select Data latch 1 to Data latch 4 corresponding to COM 1 to COM 4
independently. If logic "1s" are selected to multiple select bits, the LCD display bits are written
to all corresponding data latches.
Example:
When logic "1s" are set to all select bits C1 to C4, and logic "0s" are set to all LCD display bits D1
to D50, logic "0s" are written to Data latch 1 to Data latch 4 by one data input. This leads to turning
off the entire LCD panel.

How to Decrease Transfer Time When Unused Segments Exist
The MSM9004-03/04 can operate even if segment data is not full. Input data as in the figure
shown below. In this case, the last 4 bits are the select bits.

Recommended RC Values for MSM9004-04 Oscillation Circuit
Shown below are the recommended oscillation resistor (RO) and capacitor (CO) values for
providing frame frequency fFRM of approximately 62 Hz to 190 Hz.
• RO = 62 kW ± 5%
• CO = 0.01 mF ± 5%
(Resistance and capacitance variations due to temperature change are not included.)
For requirements of supply voltage (VDD), ambient temperature range (Ta), and frame frequency
(fFRM):
• VDD = 5.0 V
• Ta = –40 to +85°C
• fFRM = oscillation frequency

PACKAGE DIMENSIONS
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).
