Overview

The ADSP-21469 is a high-performance floating-point digital signal processor belonging to the SHARC (Super Harvard Architecture) family, operating at a clock rate of 400MHz. It is specifically designed for high-end audio applications, featuring 5Mbit of on-chip RAM and a rich set of serial interfaces including DAI, DPI, and SPI.

Why Choose This Part

The 400MHz floating-point core provides the necessary throughput for complex recursive algorithms without the scaling issues of fixed-point processors. Its 5Mbit on-chip RAM reduces latency by minimizing the need for external memory access during critical processing loops.

Applications

Professional Audio Processing
Ideal for real-time digital audio effects, equalization, and mixing consoles requiring high dynamic range.
Automotive Infotainment
Used in premium vehicle sound systems for active noise cancellation and spatial audio processing.
Industrial Control Systems
Leverages floating-point precision for complex motor control algorithms and high-speed sensor data processing.
