Description

The Fujitsu MBF200 solid-state fingerprint sensor is a rugged, thin, low power, cost effective direct-contact fingerprint image capture device. The MBF200 fingerprint sensor scans the finger at 500 dots-per-inch (dpi) and 8-bit grayscale for high-resolution fingerprint images that meet AFIS image quality standards. The MBF200 is manufactured in standard CMOS technology and integrates an 8-bit analog-to-digital converter to digitize the information from the sensor array. The MBF200 sensing area is 0.5" x 0.6" (12.8mm x 15.0mm) and passes FCC-B (8kV) and CE ESD and EMI requirements.

The Fujitsu MBF200 is a capacitive sensing device that automatically adjusts the MBF200 sensor to its optimal settings, enabling industry-leading image capture reliability for a wide range of wet, dry and damaged fingers. A hard passivation layer on the surface of the MBF200 provides excellent abrasion resistance. When a person presses their finger on the sensor, the varying capacitive values across the array are converted into an image of the MBF200 Solid-State Fingerprint Sensor fingerprint. In less than one second, the sensor can capture a fingerprint image, adapt to various finger types, process the image and authenticate a user’s identity.

Each MBF200 fingerprint sensor supports three standard bus interfaces:

1. USB 1.1 for integration into computer applications.
2. 8-bit parallel MCU interface
3. SPI interface, a serial interface with four wires.

The MBF200 has an Automatic Finger Detection (AFD) circuit that allows the sensor to enter a low power ‘sleep’mode and generate an interrupt when a finger is detected. In AFD mode the MBF200 draws less than 200µA of current. Normal image acquisition of the sensor operates at 3.3V and requires typically 20mA of current during active image capture. Silicon operating temperature is -20°C to +85°C, and storage temperature is -65°C to +150°C.

The Fujitsu MBF200 fingerprint sensor can be programmed using the DKF200 software development kit that includes the driver software and a minutia-based matching algorithm.

The Fujitsu MBF200 Solid-State Biometric Fingerprint Sensor is a robust, cost effective fingerprint image capture device with 500-dpi image resolution, low power, small size and high durability, making it an excellent choice for a wide variety of user authentication applications.
