5 General DescriptionFingerprint recognition technology is proving to be an increasingly widespread secure and accurate means of biometric identification. Eliminating the need to remember passwords, instead relying upon the individual’s unique biometric data, is increasingly proving to be a mainstream method of security entry, witnessed by an increasing stream of new fingerprint recognition equipped products. This range of fingerprint recognition devices from Holtek offers users a quick and easy means of capturing and processing fingerprint images. By integrating all the necessary electronics to convert the captured CMOS fingerprint image sensor information into USB interface compatible data, users have a means of downloading and processing the fingerprint image for integration into their own fingerprint security entry products. This is fully supported by Holtek’s Fingerprint Module Software Development Kit. Applications for these devices would include smartphones, personal computers, door entry systems etc. as well as a host of other products requiring secure identification entry.

9 Functional DescriptionThese fingerprint recognition modules contain an integrated CMOS image sensor to capture the fingerprint image data. However by also integrating the necessary electronic circuitry to convent this image data into USB interface signals, the devices contain all the necessary hardware to allow an external PC to conveniently download and process the fingerprint image data, eliminating the need to interface directly to the CMOS image sensor. As Holtek also provides a full Software Development Kit for these modules users are provided with the necessary development software to assist with rapid development of their fingerprint recognition function equipped product design.

Hardware DescriptionThese fingerprint modules contain a CMOS image sensor as well as USB signal conversion circuitry to allow the modules to communicate with an external USB interface equipped PC. As a result the only external pin connections are the two USB signal lines, power and ground lines. The USB interface is a 2.0 Full Speed type. After power on a certain amount of time, as provided in the electrical characteristics, must be allowed before any USB commands are sent to the device. The devices also contain blue LED indicator driver hardware.
