New low power 16-bit DSP device from TI targeting portable devices
TI has introduced the TMS320C5514 and TMS320C5515, a two new devices in addition to its low power 16-bit digital signal processor (DSP) C5000 platform. These new low power TMS320C55x DSPs provide up to 120MHz, with high integration and 20 percent performance boost for portable devices.
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 low power TMS320C55x DSPs features additional encode and decode algorithms in voice, audio and portable communications applications, and more real-time diagnostics in medical end equipments. These devices also integrate power management features, such as on-chip LDOs (low-dropout regulators), and dynamic voltage and frequency scaling.
The key features of the C5514 DSP are,
Three on-chip LDOs, one each for the DSP core, USB and analog subsystems
SDRAM and mobile SDRAM support for power sensitive applications
High-integrated peripherals such as high-speed USB 2.0, I2S, UART, SPI, MMC/SD and GPIOs
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
The key features of the C5515 DSP in addition to C5514 are,
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, with easy migration options to build robust product families
