32-bit fingerprint recognition reference design

29 January 2003 Electronics Technology

A fingerprint recognition reference design being introduced by Motorola can make it easier for designers to incorporate the company's proven 32-bit ColdFire MCF5249 microprocessor (MPU) into biometric devices. Second in a series of application-specific reference designs based on Motorola's ColdFire architecture, this design includes application notes, design schematics and software.

The reference design provides a detailed explanation of methods for connecting the fingerprint sensor to the ColdFire MCF5249 MPU. The design includes initialisation and driver software, as well as Acter AG's fingerprint recognition software, which manufacturers can license directly from Acter AG. The ColdFire MPU also comes equipped with interfaces for various memory types including SDRAM, Flash, hard disk and smart memory, which allow the design to be implemented using different template storage methods.
