Precautions for Light
Light has characteristics to move electrons in the integrated circuitry of semiconductors,
therefore may change the characteristics of semiconductor devices when irradiated with light.
Consequently, the users of the packages which may expose chips to external light such as
COB, COG, TCP and COF must consider effective methods to block out light from reaching
the IC on all parts of the surface area, the top, bottom and the sides of the chip. Follow the
precautions below when using the products.
1. Consider and verify the protection of penetrating light to the IC at substrate (board or
glass) or product design stage.
2. Always test and inspect products under the environment with no penetration of light.

INTRODUCTION
The S6A0093 is an LCD driver and controller LSI for liquid crystal dot matrix character display systems. It can
display 2 or 3 lines of 16 characters with 5 x 8 dots format. It is capable of interfacing various microprocessors,
supporting the 4-bit, 8-bit parallel modes and the clock synchronized serial mode. Voltage converter, oscillator,
voltage regulator, voltage follower and bias circuit are built in the IC. The double height character mode and line
vertical scroll functions are supported.
