Texas Instruments Incorporated (TI) rolls out the TMS3230C5515 DSP based Fingerprint Development Kit. It's a complete signal chain solution for Rs.3,647.98 ($79) which enables easy integration of fingerprint biometric features in portable applications with a longer battery life and a reduced time to market.

This robust development kit includes a core board based on TI's C5515 digital signal processor (DSP), two widely-used fingerprint sensor types (swipe and optical), as well as optimised 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.

The C5515 Fingerprint Development Kit provides fast and accurate fingerprint matching by leveraging the strength of 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 0.15mW/MHz, thereby extending battery life for portable end equipments. This 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.

The kit includes a core board with TI's new low power C5515 DSP to conserve power at an exceptional level for portable end equipments. It has an extension board including power supply circuitry, LED and sound indicators, as well as push buttons for simple operation. The board also includes an USB2.0 and a RS232 port to communicate with PCs.

It includes two widely-used fingerprint sensor types, for seamless integration into final products- One AuthenTec swipe sensor, ATW310 and another Tooan optical sensor, OP-100R. AuthenTec's ATW310 is a small form factor fingerprint sensor offering the power and memory efficiency needed for fast fingerprint recognition in today's mobile and access control devices

A production quality demo and its .out file enables users to experience final product performance. The demo is based on a fingerprint-matching algorithm running on the C5515 optimised to recognise prints in less than one second (1:50 matching) with a false acceptance rate (FAR) of less than 0.001 per cent and a false rejection rate (FRR) of less than one per cent to ensure system reliability. It offers simplified application source code to educate novice users about how to develop a product with fingerprint features.

It has hardware design collateral including schematics and Gerber files, in addition to technical documents such as the user guide and application notes.

The very small form factor solution (the core board is only 30mm by 30mm, the extension board is 70mm by 30mm) meets portable application requirements and the two board architecture provides great design flexibility, allowing customers to reuse their designs to develop scalable product lines

TMS320C5515 DSP is based on the TMS320C55x architecture that achieves code execution efficiency and reduces power consumption through three main areas of increased parallelism from the dual multiply-accumulate (MAC) units, higher data bandwidth to on-chip memory through multiple simultaneous accesses and advanced DSP addressing features.

The features are extensive power management features such as memory retention, real-time clock (RTC) only mode and clock gating to maximise battery life for portable devices and highly-integrated peripherals — including a high-speed USB2.0, three on-chip low-dropout regulators (LDO), UART, SPI and GPIOs — as well as up to 320KB of on-chip memory saves system costs and power enabling new emerging applications
