FP20 is a fingerprint and fingerprint processor combo chip design fingerprint identification module secondary development, with small size, low power consumption, simple interface, high reliability, small fingerprint template (496 bytes), large capacity fingerprint recognition (2000 Fingerprint response time of less than one second), etc., can be very easy to embed a user's system components to meet customer demand for fingerprint identification products.

The main functions include the following:
■        Send and receive commands via UART
■        Achieve the minimum storage conditions fingerprint data registration and comparison: 496 bytes fingerprint template
■        Optical reflection fingerprint sensor
■        1: N identification and 1:1 verification function
■        Compared with circulating collection function (Identify Free): Host HOST after sending the command module has been in fingerprint matching and comparing the results returned HOST
■        Fingerprint feature data read / write function
■        The security level can be properly adjusted
■        Fingerprint and extract eigenvalues upload, download fingerprint feature value and the current collection of fingerprint matching function
■        The baud rate can be set
■        You can set the device number
■        You can set a password to access the module (14 digit character password), so that the module is password protected mode, which greatly improves the security of communications.
