ML67Q5250

OKI Semiconductor ML67Q5250 DFT Based Fingerprint Authentication LSI PEDL67Q5250-01 Issue Date: Nov. 9, 2007 Preliminary GENERAL DESCRIPTION The ML67Q5250 is a single chip LSI that executes fingerprint authentication without external memory by using the embedded fingerprint authentication accelerator. This fingerprint authentication accelerator uses DFT(Discrete Fourier Transform) based algorithm licensed from Precise Biometrics, and supports AuthenTec's slide sensors and certain touch sensors from several sensor manufacturers. Besides the ML67Q5250 has the secure circuit to protect enrolled fingerprint data from unauthorized access. Thus this LSI helps customers quickly design new products that offer convenient security as far as high performance fingerprint authentication, low cost and high level of security. FEATURES Fingerprint authentication - DTF (Discrete Fourier Transform) based algorithm licensed from Precise Biometrics This DFT based algorithm achieves a lower FTE (False To Enrollment rate) and a higher authentication accuracy especially when a slide sensor is used, as compared to the minutiae algorithm. - Easy-to-use The fingerprint authentication is performaed by the fingerprint authentication accelerator, which does not ask customers for so complicated control. - No external memory Customer’s application program and up to 15 fingerprint data can be stored in the embedded Flash memory on the ML67Q5250. No external memory is required, when a slide sensor is use...
