TI launched a solution based on low-power TMS320C5515 DSP
A few days ago, Texas Instruments (TI) announced the launch of the TMS3230C5515 fingerprint development kit, a complete signal chain solution priced at only $ 79, which can easily integrate fingerprint biometrics features and shorten time to market. The core circuit board of this highly robust development kit includes the TI C5515 digital signal processor (DSP), two widely used fingerprint sensors (slip and optical) and optimized application software, which simplifies product creation and implementation. For new users of fingerprint application development, the kit can significantly reduce the product design cycle by 9 to 12 months.
C5515 Fingerprint Development Kit provides fast and accurate fingerprint matching function, which can make full use of the advantages of DSP to perform important functions of fingerprint algorithm, such as filtering, classification and conversion. As the industry's lowest power 16-bit fixed-point DSP, C5515 can achieve the best processing performance at a power consumption as low as 0.15mW / MHz, which can extend the battery life of portable terminal 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 keys and storage devices, PC user identification, and attendance monitoring systems.

Features and advantages of TMS320C5515 fingerprint development kit:
The kit includes:
· The core circuit board using TI's new low-power C5515 DSP can significantly reduce the power consumption of portable terminal equipment;
· Expansion circuit board including power circuit system, LED and sound indicator and simple operation button. The circuit board also contains USB2.0 and RS232 ports, which can communicate with PC;
· Two widely used fingerprint sensors can be seamlessly integrated into the final product:
o An AuthenTec sliding sensor ATW310
o One Tooan optical sensor OP-100R
AuthenTec's ATW310 is a small fingerprint sensor that can provide the high power and high memory efficiency required for current mobile and access control devices to quickly perform fingerprint recognition;
· Production-quality demonstrations and their .out files help users experience the final product performance. The demonstration uses a fingerprint matching algorithm running on C5515, optimized to perform under high performance 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% Imprint recognition (1:50 match), which can ensure the reliability of the system;
· Simplified application source code can help new users understand how to develop products with fingerprint features;
· The hardware design not only provides schematics and Gerber files, but also provides technical documents such as user guides and application manuals;
· This extremely small solution (the core circuit board area is only 30 × 30 mm, the expansion circuit board area is 70 × 30 mm) can fully meet the needs of mobile applications, and the dual circuit board architecture can achieve high design flexibility Performance, enabling users to reuse design solutions to develop scalable product lines.
The main features and advantages of TMS320C5515 DSP:
· TMS320C55x architecture can achieve excellent code execution efficiency and reduce power consumption through the following three aspects: double parallel accumulation (MAC) unit to improve parallelism, through multiple simultaneous access to improve the data bandwidth of on-chip memory, and support advanced DSP addressing characteristics;
· Utilize rich power management features such as memory retention, real-time clock only (RTC) mode, and clock gating to maximize the battery life of portable devices;
· Highly integrated peripherals (including high-speed USB 2.0, three on-chip low-dropout regulators (LDO), UART, SPI, and GPIO, etc.) and up to 320KB of on-chip memory can significantly save system cost and power, and support emerging applications.
