TI Expands DSP Platform Offerings with Two New Low-power Devices

Texas Instruments Inc. has added two new devices, the TMS320C5514 and TMS320C5515, to the industry's lowest power 16-bit digital signal processor (DSP) C5000 platform. TI has announced 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 LDOs (low-dropout regulators), as well as dynamic voltage and frequency scaling, so customers can maximize and efficiently manage battery life for portable devices.

Key features and benefits of the C5514 DSP include:
- Three on-chip LDOs, one each for the DSP core, USB and analog subsystems
- SDRAM and mobile SDRAM support for power sensitive applications
- Highly-integrated peripherals – including a high-speed USB 2.0, I2S, UART, SPI, MMC/SD and GPIOs
- Up to 256kB of on-chip memory saves both power and system cost by reducing the need for external memory
- Dynamic voltage and frequency scaling help to maximize battery life in portable applications

The C5515 DSP, meanwhile, builds on C5514 with an additional 64kB on-chip memory (320kB total). It has up to 1024-point programmable FFT hardware accelerator; integrated LCD display controller; and 10-bit 4-channel SAR ADC.

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, developers can also take advantage of the new TMDX5515EZDSP.
