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.

S6B33C1 PRELIMINARY VER 0.0 96 RGB SEGMENT & 66 COMMON DRIVER FOR 4,096 COLOR STN LCD

INTRODUCTION

S6B33C1 is a mid-display-size-compatible driver for liquid crystal dot matrix gray-scale graphic systems. With on-

chip RC oscillator circuit, the display-timing signal is generated without being sent from MPU. Also, it is capable of

operating with 8bit 68/80-series MPU in asynchronous. Due to the internal bit-map display RAM of 96

�

12-bit,

S6B33C1 is capable of operating max. 96 RGB x 65 dot LCD panels in low-power consumption. Being the segment

RGB 3-output, one pixel is 12-bit data and S6B33C1 can display 256 or 4,096 color.
