ML67Q5250 - Fingerprint Authentication solution
The ML67Q5250 is dedicated fingerprint authentication MCU with embedded secure Flash. The entire fingerprint authentication process, i.e capturing fingerprint image from external sensor, enrollment of fingerprint data and authentication is done "match-on-device".
The fingerprint authentication is processed by a hardware accelerator and requires no external memory. It uses high accuracy algorithm licensed from Precise Biometrics suitable for slide sensors.
The ML67Q5250 provides a high speed, high accuracy, high security and low system cost solution. |
The ML67Q5250 is available now for sampling , volume shipment
from
April 2008 onwards.
The ML67Q5250 CPU board and Software Development Kit (SDK) are available
from December 2007
