Texas Instruments Inc. adds the TMS320C5514 and TMS320C5515 to its low*power 16bit DSP C5000 platform. In addition, to help customers get started quickly, TI is announcing two evaluation options including a full-featured TMDXEVM5515 evaluation module and a new low cost TMDX5515EZDSP.

These new low-power TMS320C55x DSPs provide a 20 percent performance increase, up to 120MHz, with higher integration to ease system level development. This allows customers to maintain very low power levels while adding features such as additional encode and decode algorithms in voice, audio and portable communications applications, as well as more real-time diagnostics in medical end equipments. These devices also integrate power management features, such as on-chip low-dropout regulators, as well as dynamic voltage and frequency scaling, so customers can maximize and efficiently manage battery life for portable devices.

The C5514 DSP key features three on-chip LDOs, one each for the DSP core, USB and analog subsystems. The device packs SDRAM and mobile SDRAM support for power sensitive applications. The

highly-integrated peripheralshigh-speed USB 2.0, I?S, UART, SPI, MMC/SD and GPIOsreduce system cost and enable more user-friendly portable features. The C5514 also includes up to 256Kbyte of on-chip memory that saves both power and system cost by reducing the need for external memory. The devices offers dynamic voltage and frequency scaling help to maximize battery life in portable applications.

The C5515 builds on C5514 with an additional 64Kbyte on-chip memory (320Kbyte total). The C5515 features up to 1024-point programmable FFT hardware accelerator. The device's integrated LCD display controller and 10bit four-channel SAR ADC reduce system cost and enable more user-interactive portable features. In addition, the C5515 is scalable and pin-to-pin compatible with the C5514, which provides customers with the flexibility to choose the right device for their application with easy migration options to build robust product families.

The full-featured TMDXEVM5515 evaluation module is compatible with the C5514 and C5515 low-power DSPs and comes ready with a complete software library and several application demos. Additionally, building on TI's commitment to offer easy, low-cost evaluation options, developers can also take advantage of the new TMDX5515EZDSP. Priced at $79, this USB stick requires no other components or cables for hassle-free development and a simple out-of-the-box experience. This very low cost, yet powerful development tool, integrates a number of capabilities including on-board emulation for rapid creation of DSP applications.

Free samples are available now for the TMX320C5514 and TMX320C5515. Full production of the C5514 is priced at $6.50 and the C5515 is priced at $7.65 both in 1,000 unit-quantities. To jumpstart development, developers can use the TMDXEVM5515 DSP evaluation module, which is open for order-entry today and priced at $395.00. Additionally, for a lower cost evaluation alternative, the TMDX5515EZDSP is also open for order-entry today and is priced at $79.
