Computer access and network securityՕPortable device security Mobile fingerprint image capture ՕAccess control: doors, locks, and safes ID tokens and Smart Cards ՕTransportation security: vehicles, cargo Medical: HIPAA, patient records privacy ՕFinance: secure transactions, audit trail > The Fujitsu MBF200 is a 500 DPI 8-bit grayscale solid-state capacitive fingerprint sensor that reliably captures fingerprint 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 finger 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 fingerprint image is determined by measuring the capacitance at each pixel and converting that data into an 8-bit grayscale image. > Rugged, solid-state capacitive fingerprint sensorՕHigh resolution 500 DPI, 8-bit grayscale imager Large image area:Ֆ12.8mm x 15.0mm (0.5" x 0.6") 256 x 300 pixel array (50um pitch)֕Programmable gain adapts to different fingersSmall: 24mm x 24mm x 1.4mm LQFP package ՕInterfaces: USB1.1, 8-bit MCU, SPI Durable:ՖESD: FCC-B/CE certifiedOperating temperature: -20ְC to +85CЕIntegrated 8-bit analog-digital converterAuto finger-detection circuit ՕLow Power3.3V to 5.0V֖20mA active, <200A sleep, 20յA standby >

SPI (Slave) bus mode uses the following pins: SCLK, SCS > In SPI Slave Mode, the sensor can operate in either SPI mode (0, 0) where CPOL = 0 and CPHA = 0 or SPI mode (1, 1) where CPOL = 1 and CPHA = 1. The SPI Master may clock in commands and clock out data up to 12 Mbits per second. The SPI Master can write and read the registers of the sensor even when the internal 12 MHz multivibrator or XTAL1/XTAL2 oscillator is halted.MOSI bits are sampled on the rising edge of SCK ՕMISO bits change on the falling edge of SCK SCK can be idle in either a high or...
