INTRODUCTION
The S5K433CA and S5K433LA are highly integrated single chip CMOS image sensors fabricated by
SAMSUNG 0.35
m CMOS image sensor process technology. It is developed for imaging application to realize
high-efficiency and low-power photo sensor. The sensor has 640 x 480 effective pixels with 1/4 inch optical
format. The sensor has on-chip 10-bit ADC blocks to digitize the pixel output and also on-chip CDS to reduce
Fixed Pattern Noise (FPN) drastically. With its few interface signals and 10-bit raw data directly connected to the
external devices, a camera system can be configured easily. S5K433CA is suitable for a camera system with
standard 3.3V logic operation and S5K433LA is suitable for low power camera module with 2.8V power supply.
