Overview

The TMS320C5535 is a low-power, fixed-point digital signal processor (DSP) from Texas Instruments. It features a C55x architecture with a clock rate up to 100MHz, making it suitable for demanding signal processing tasks. This DSP integrates 320kB of RAM and 128kB of ROM, along with various interfaces to support a wide range of embedded applications.

Why Choose This Part

Engineers choose the TMS320C5535 for its balance of high performance and low power consumption, crucial for battery-operated devices. Its C55x architecture, coupled with dual MAC units and a hardware FFT accelerator, delivers efficient execution of signal processing algorithms. The extensive on-chip memory (320kB RAM, 128kB ROM) and multiple peripheral interfaces (I2C, I2S, USB, SPI, UART, MMC/SD) simplify system integration.

Applications

Portable Audio Devices
Its low power consumption (0.15mW/MHz @ 1.05V, 50MHz) and integrated audio interfaces make it ideal for portable audio players, voice recorders, and other battery-powered audio equipment.
Voice Over IP (VoIP) Handsets
The DSP capabilities, including dual MAC units (up to 200 MMACS) and an FFT hardware accelerator, are well-suited for processing voice communication algorithms in VoIP phones and conferencing systems.
Digital Still Cameras
The image processing requirements of digital cameras can leverage the DSP's high-performance core and memory resources for tasks like filtering, compression, and feature extraction.
Biometric Authentication Systems
Complex algorithms for fingerprint, voice, or facial recognition benefit from the TMS320C5535's signal processing power, enabling accurate and efficient biometric authentication.
Medical Monitoring Devices
The DSP can process physiological signals from various sensors in medical devices, such as ECG monitors or patient vital sign monitors, where real-time analysis is critical.
Active Noise Cancellation
The ability to perform high-speed, fixed-point calculations makes the TMS320C5535 suitable for implementing active noise cancellation algorithms in headphones or industrial environments.
