090425MBF200 Solid State Fingerprint Sensor Overview The Fujitsu MBF200 is a 500 DPI 8-bit grayscale solid-state capacitive ngerprint sensor that reliably captures ngerprint images. The 2-dimensional array consists of 256 x 300 pixels manufactured in standard CMOS. The sensing area is 12.8mm x 15.0mm (0.5" x 0.6"). Each pixel is made up of a metal electrode, which acts as one plate of a capacitor. The contacting nger acts as the second capacitor plate. A passivation layer on the device surface forms the dielectric between these two plates and provides abrasion and chemical resistance. The ngerprint image is determined by measuring the capacitance at each pixel and converting that data into an 8-bit grayscale image.
