| TCM5020ALU CMOS Area Image Sensor TCM5020ALU 1/7 Inch 110 k Pixel CMOS B/W Image Sensor The TCM5020ALU is a CMOS b/w (= black and white) image sensor that meets with CIF format. It enables all pixel signals to be output in sequence each 1/30 s. (progressive scanning) This element is equipped with 290 vertical and 367 horizontal signal pixels, and the image size meets with 1/7 inch optical format. The package with lens is applicable. This small lens unit package realize small-scaled system. Use of the CMOS process enables low power-consumption operations with a single power voltage driving. It is perfect for use as an image input device for mobile equipments. WQFN16-C-S420-160A Weight: 0.5 g (typ.)
