TI's new devices for 16-bit DSP platform, especially for portable devices

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.

C5514 DSP key features and benefits:

· 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 – reduce system cost and enable more user-friendly portable features

· Up to 256 KB 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


C5515 DSP key features and benefits (in addition to C5514):

· C5515 builds on C5514 with an additional 64KB on-chip memory (320KB total)

· Up to 1024-point programmable FFT hardware accelerator

· Integrated LCD display controller and 10-bit 4-channel SAR ADC reduce system cost and enable more user-interactive portable features

· Scalable and pin-to-pin compatible with the C5514, provides customers with the flexibility to choose the right device for their application with easy migration options to build robust product families
