ADSP-21479KCPZ-1A

Digital Signal Processor Dsp Overview

The ADSP-21479KCPZ-1A is a high-performance 32-bit/40-bit floating-point digital signal processor from the SHARC family, optimized for audio processing. It features a single-instruction, multiple-data (SIMD) computational architecture with two processing elements operating at up to 300 MHz. The device includes 5 Mbits of on-chip RAM and 4 Mbits of on-chip ROM. Key peripherals include a Digital Applications Interface (DAI), eight serial ports, an S/PDIF transceiver, four asynchronous sample rate converters, and a precision clock generator. It supports automotive applications via AEC-Q100 qualification.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'KCPZ-1A' against the manufacturer's current ordering guide, as package availability may vary. Confirm RoHS compliance status and lead times directly with authorized distributors or Analog Devices. Ensure the procurement channel provides valid traceability documentation for automotive-grade components.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high throughput in audio decoding or filtering. Compare memory sizes with the ADSP-21477 (2 Mbit RAM) and ADSP-21478 (3 Mbit RAM + 4 Mbit ROM) if storage requirements differ. Verify that the 100-lead LQFP package meets board space constraints, noting it lacks the external port available in the BGA variant.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2147x family of SHARC processors. It shares source code compatibility with previous generations like the ADSP-2136x and ADSP-2146x. The KCPZ-1A designation indicates a specific temperature range and package type within the broader 21479 product line.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible replacements within the same package are limited. Consider the ADSP-21478 for lower memory needs or the ADSP-21477 for cost-sensitive designs. Cross-family migration to newer SHARC models requires software adaptation despite architectural similarities.
