Oki Electric Industry Co. Ltd has unveiled the ML67Q5250 application-specific standard LSI with a fingerprint authentication accelerator. By using this LSI, customers can easily create a cost effective high-speed, high-accuracy and low power consumption fingerprint authentication system.

This fingerprint authentication accelerator uses a Discrete Fourier Transform algorithm licensed from Precise Biometrics, and optimized for AuthenTec's slide fingerprint sensors. The accelerator executes all fingerprint authentication processes, from capturing fingerprint image to authentication, within 0.8 second using 32MHz system clock.

The LSI does not require external memory as the embedded flash stores up to 15 fingerprint templates and the customer's application program. ML67Q5250 is highly optimized for AuthenTec's slide fingerprint sensors for fast authentication and supports certain touch sensors and offers function to protect the fingerprint data from unauthorized access, enabling high-level security systems.

Battery-run SDK
In addition, the ML67Q5250 includes GPIOs, synchronous SIO, asynchronous SIO, USB2.0 FS device controller, IC card IF and SPIs. The LSI also offers software development kit (SDK) embedded with AuthenTec's slide sensors. The business-card-size board connects with ARM development kits and enables enrollment and authentication with batteries instead of connecting to a PC.

"We believe this chip will offer an excellent solution to customers who are looking for a cost effective yet easy-to-use, high-performance fingerprint authentication system, especially when customers' current system do not have enough performance and memory for fingerprint authentication," said Masahiko Morioka, president of Silicon Solutions Co. at Oki.

"We believe that this new Oki LSI and reference design with AuthenTec sensors will further expand new applications for fingerprint sensors," said Art Stewart, AuthenTec VP of worldwide sales. "This new turnkey solutionbased in part on AuthenTec's patented TruePrint technologywill support the continued rapid global adoption of fingerprint biometrics by helping original equipment manufacturers quickly design products that offer convenient security to today's consumer."

Oki plans to provide a SDK optimized for some of the touch sensors, and support a fingerprint authentication module. The company will also develop products with the fingerprint authentication accelerator that are compliant with ISO standard, and will expand its LSI business in the biometric authentication market.
