ADSP-21477KSWZ-1A

Digital Signal Processor Dsp Overview

The ADSP-21477KSWZ-1A is a high-performance 32-bit/40-bit floating-point digital signal processor from the SHARC family, optimized for audio processing. It operates at a maximum clock frequency of 200 MHz and features a Single-Instruction, Multiple-Data (SIMD) computational architecture with two processing elements. The device includes 2 Mbits of on-chip RAM and lacks internal ROM. It is housed in a 100-LQFP-EP package and supports VISA instruction sets for code efficiency.

Digital Signal Processor Dsp Feature Summary

• 200 MHz operating frequency with SIMD architecture delivering up to 1.8 GFLOPS at peak speeds
• 2 Mbits of on-chip SRAM configured across four memory blocks
• Integrated S/PDIF transceiver, eight serial ports, and four asynchronous sample rate converters
• Digital Applications Interface (DAI) with flexible signal routing unit (SRU)

Digital Signal Processor Dsp Applications

• High-performance audio processing and decoding
• Medical imaging systems
• Communications equipment
• Test and measurement instrumentation

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix KSWZ-1A against the manufacturer's current ordering guide to confirm package type, temperature range, and automotive qualification status. Ensure compatibility with existing PCB footprints for the 100-lead LQFP-EP package before procurement.

Digital Signal Processor Dsp Selection Notes

Select this model when 200 MHz performance and 2 Mbits of internal memory are sufficient. Compare with the ADSP-21478 or ADSP-21479 if higher clock speeds or larger on-chip memory capacities are required for the application.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2147x series, which shares source code compatibility with previous SHARC generations like the ADSP-2126x and ADSP-2136x. The KSWZ-1A designation identifies the specific speed grade and package variant within this family.

Digital Signal Processor Dsp Replacement Considerations

Direct functional replacements include the ADSP-21478KSWZ-1A and ADSP-21479KSWZ-1A, which offer increased memory and clock speeds while maintaining pin and software compatibility.
