TITMS320C5535 Low-Power C55x DSP

Overview

The TMS320C5535 is a low-power fixed-point digital signal processor from Texas Instruments' C55x family. It is designed for embedded applications that need efficient real-time signal processing rather than general-purpose computing. With on-chip ROM, SRAM, and common serial interfaces, it fits compact designs that handle audio, control, and communication tasks.

Why Choose This Part

This part combines a fixed-point DSP core with useful on-chip memory and a broad set of serial peripherals, which helps reduce external component count. Its low-power focus makes it a practical choice for embedded signal-processing tasks where efficiency matters. The 100 MHz clock rate and C55x architecture are well suited to deterministic real-time processing workloads.

Applications

Getting Started

A practical starting point is a TI evaluation or development board for the C5535 family, along with Code Composer Studio and the TI C55x software tools. For bring-up, focus first on clocking, power rails, and access to the serial ports you plan to use, then verify basic memory and boot configuration before loading your application. TI application notes and board support packages are especially useful for setting up audio and USB-based designs.
