TI’s $79 fingerprint dev kit cuts design cycle by 9 to 12 months

ti-c5515Houston, Tex. — Texas Instruments Inc. (TI) has launched its TMS320C5515 Fingerprint Development Kit, a complete solution aimed at easy integration of fingerprint biometric features in portable applications, at a price of $79.

The low-cost development kit includes a core board based on TI’s C5515 digital signal processor (DSP), two widely-used sensor types (swipe and optical), and optimized application software to ease product creation and implementation. For customers new to fingerprint application development, the kit can dramatically reduce the product design cycle by 9 to 12 months, said TI.

TI said the C5515 Fingerprint Development Kit provides fast and accurate fingerprint matching by leveraging the DSP to perform critical functions in the fingerprint algorithm such as filtering, sorting and transforming. As the industry’s lowest power 16-bit fixed point DSP, the C5515 provides optimal processing performance at an active power level as low as 0.15 mW/MHz, which extends battery life for portable end equipment, said TI.

The development kit can be used to create a variety of portable applications, including physical access control products (electronic door locks and safe boxes), USB smart keys and storage device, PC user identification, and time and attendance monitoring systems.

In addition to the C5515 DSP-based core board, AuthenTec swipe sensor and an optical sensor, the kit also contains an extension board that includes power supply circuitry, LED and sound indicators, as well as pushbuttons for simple operation. The board also includes an USB 2.0 and a RS232 port to communicate with PCs.

The kit also includes a production quality demo and its .out file enables users to experience final product performance, said TI. The demo is based on a fingerprint-matching algorithm running on the C5515 optimized to recognize prints in less than one second with a false acceptance rate (FAR) of less than .0015 percent and a false rejection rate (FRR) of less than one percent to ensure system reliability. It also provides hardware design collateral including schematics, Gerber files, and technical documents such as the user guide and application notes.

The small form factor — the core board measures 30 x 30 mm and the extension board measurers 70 x 30 mm — meets portable application requirements while allowing customers to reuse their designs to develop scalable product lines

TI said the TMS320C55x architecture achieves code execution efficiency and reduces power consumption through three main areas: increased parallelism from the dual multiply-accumulate (MAC) units, the higher data bandwidth to on-chip memory through the multiple simultaneous accesses, and the advance DSP addressing features. It also features extensive power management such as memory retention, real-time clock (RTC) only mode and clock gating to maximize battery life for portable devices.

Other features include highly-integrated peripherals including a high-speed USB 2.0, three on-chip low-dropout regulators (LDO), UART, SPI and GPIOs as well as up to 320 KB of on-chip memory.
