The MBF200 Solid-State Fingerprint Sensor is a high-performance, low-power, low-cost capacitive sensor that can be used for secure access to databases, networks, local storage, portable fingerprint acquisition, smart cards, ATM transaction identity verification, cellular phone-based security access, access control and monitoring for home, auto, office, etc.
The MBF200 is a capacitive solid‑state fingerprint sensor with a 256 × 300 pixel array and 500‑dpi resolution. It operates from 3.3 V to 5 V and consumes less than 70 mW at 5 V. The document provides detailed block diagrams, connection schematics, pin lists, and register descriptions for integrating the sensor into various systems.
Included are recommended power‑ground layouts, sensor orientation guidelines, and mode‑selection information for microprocessor, SPI, and USB interfaces, enabling developers to configure and program the device for secure access applications.
