World's smallest fingerprint matching module features OKI single chip solution

SAN DIEGO, USA: The new OKI Semiconductor MK67Q5250 fingerprint matching module is designed to speed implementation of automated fingerprint identification and access control in applications ranging from locks and garage door openers to portable devices, computer workstations and POS terminals.

This low-power module, measuring less than 1 sq. inch in size, utilizes the OKI ML67Q5250 LSI MCU that has been factory programmed to control the module's AES2510 fingerprint imaging sensor from Authentec; perform fingerprint processing and matching; store biometric control code, application code and templates; and communicate with a host processor. SPI is the default communications interface to the host processor from the module. The module can be configured for other communications protocols such as UART or USB.

According to Alec Melnick, Sr. Product Marketing Manager, OKI: "The OKI Semiconductor MK67Q5250 is designed to allow a system designer to use this pre-assembled module to quickly evaluate and integrate biometrics into their system. Factory programming of the MK67Q5250 eliminates the need for writing fingerprint processing code while maintaining a high level of control over the fingerprint enrollment and verification process."

The ML67Q5250 is the industry's only single-chip fully-integrated fingerprint authentication system. Alternative solutions typically employ costly and power-consuming high performance microcontrollers or processors that require external memory. By using the available software development kit (SDK) the designer does not need to write or verify any biometric software.

The designer, using standard code development tools, can write application specific code for the on-chip 32 MHz ARM7 processor and combine it with the SDK-generated biometric software to meet the needs of their specific application.
