ML67Q5250
The application specific LSI for fingerprint authentication systems
Features
The ML67Q5250 is a fingerprint authentication LSI, which executes entire fingerprint authentication process, i.e capturing fingerprint image from external sensor, enrollment of fingerprint data and authentication on the device.
The fingerprint authentication is processed by hardware accelerator with no external memory. And it uses high accuracy algorithm licensed by Precise Biometrics, which is suitable for slide sensors.
Thus the ML67Q5250 provides a high speed, high accuracy, high security, and low system cost solution.
