Overview

The TMS320C5535AZAY10 is an ultra-low-power fixed-point digital signal processor (DSP) based on the C55x core, operating at 100MHz. It is designed to deliver high performance for signal processing tasks while maintaining a tiny power footprint, drawing only 8.5mA at 1.3V during full operation. The integration of a hardware FFT accelerator and 320kB of on-chip RAM makes it highly effective for real-time audio and sensor data processing.

Why Choose This Part

The primary advantage is its exceptional power efficiency, featuring standby currents as low as 150uA and dedicated hardware for FFT computation which reduces cycles needed for common signal processing tasks. It offers a rich set of peripherals including USB 2.0 High-Speed, an integrated LDO, and 320kB of RAM, minimizing the need for external components in compact 144-LFBGA designs.

Applications

Portable Audio Devices
Utilizes the integrated I2S interfaces and low power consumption for digital voice recorders, MP3 players, and audio headsets.
Biometric Recognition
Handles fingerprint or voice recognition algorithms locally using the hardware FFT accelerator to offload the main CPU.
Industrial Sensor Fusion
Processes multiple sensor inputs via SPI, I2C, and ADC channels to perform real-time vibration analysis or predictive maintenance.
Medical Monitoring
Ideal for battery-powered pulse oximeters and ECG monitors that require continuous signal filtering and low standby current.
