TITMS320C5505
Overview
The TMS320C5505 is a high-performance, ultra-low-power fixed-point Digital Signal Processor (DSP) based on the C55x CPU core. Operating at up to 150MHz, it features 320kB of on-chip RAM and a dedicated FFT hardware accelerator to offload complex arithmetic tasks. This processor is specifically designed for applications requiring high computational efficiency with minimal power consumption, such as portable audio and voice processing.
Why Choose This Part
The C55x architecture provides two ALUs and five internal data buses, allowing for high instruction throughput per clock cycle. Its ultra-low power profile, featuring core power consumption as low as 0.15 mW/MHz, significantly extends battery life in portable designs. The integration of 320kB RAM and a bootable ROM reduces external component count and PCB complexity.
Applications
Key Specifications
Getting Started
Development typically requires Texas Instruments Code Composer Studio (CCS) and a compatible JTAG emulator for debugging. The TMDX5505EZDSP USB Stick is a common entry point for evaluation, providing an integrated debugger and access to the DSP's peripheral pins. Engineers should leverage the C55x Chip Support Library (CSL) to quickly configure the I2C, SPI, and USB interfaces.
