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 for 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"
