Texas Instruments (TI) announced the TMS3230C5515 fingerprint development kit, a complete signal chain solution for just $79, that easily integrates fingerprint biometrics and reduces time-to-market. The core board of the High Robustness Development Kit includes the TI C5515 Digital Signal Processor (DSP), two widely used fingerprint sensors (sliding and optical), and optimized application software to simplify product creation and implementation. For new users of fingerprint application development, the kit significantly reduces the product design cycle by 9 to 12 months.

The C5515 Fingerprint Development Kit provides fast and accurate fingerprint matching to take full advantage of the DSP's ability to perform important fingerprinting functions such as filtering, sorting, and conversion. The C5515 is the industry's lowest power 16-bit fixed-point DSP for optimal processing performance at power consumption as low as 0.15 mW/MHz, extending battery life in portable devices. The development kit can be used to create a variety of portable applications, including physical access control products (electronic door locks and safes, etc.), USB smart key and storage devices, PC user identification, and attendance monitoring systems.

Features and benefits of the TMS320C5515 Fingerprint Development Kit:
The kit includes:
• The core board with TI's new low-power C5515 DSP significantly reduces the power consumption of portable terminal devices;
• Expansion boards including power circuitry, LED and audible indicators, and simple operation buttons. The board also includes USB 2.0 and RS232 ports to communicate with the PC;
• Two widely used fingerprint sensors for seamless integration into the final product:
o An AuthenTec wiper sensor ATW310
o A Tooan optical sensor OP-100R
• AuthenTec's ATW310 is a small fingerprint sensor that provides the high power and memory efficiency required for fast fingerprinting of current mobile and access control devices;
• Production quality demos and their .out files help users experience end product performance. The demo uses a fingerprint matching algorithm running on the C5515 that is optimized to perform in less than 1 second, with a false acceptance rate (FAR) of less than 0.001% and a false rejection rate (FRR) of less than 1%. Blot identification (1:50 match) to ensure system reliability;
• Simplified application source code helps new users understand how to develop products with fingerprint characteristics;
• The hardware design not only provides schematics and Gerber files, but also provides technical documentation such as user guides and application notes.
• This extremely small form factor (core board area of ​​only 30 mm x 30 mm, extended board area of ​​70 mm x 30 mm) meets the needs of mobile applications and is designed with dual board architecture High flexibility allows users to reuse design solutions to develop scalable product lines.
Key features and benefits of the TMS320C5515 DSP:
• The TMS320C55x architecture delivers excellent code execution efficiency and reduces power consumption by increasing parallelism through a multiply-accumulate (MAC) unit, increasing data bandwidth on-chip memory through multiple simultaneous accesses, and supporting advanced DSP addressing characteristics;
• Maximize battery life in portable devices with rich power management features such as memory retention, real-time clock only (RTC) mode, and clock gating;
• Highly integrated peripherals (including Hi-Speed ​​USB 2.0, 3 on-chip low-dropout regulators (LDOs), UART, SPI, and GPIO) and up to 320KB of on-chip memory save significant system cost and power for emerging applications.
