ADSP-21571CSWZ-5

Digital Signal Processor Dsp Overview

The ADSP-21571CSWZ-5 is a dual-enhanced SHARC+ high-performance floating-point digital signal processor from Analog Devices. It features two SHARC+ cores operating at a maximum clock frequency of 500 MHz, providing up to 3 Mb (384 kB per core) of L1 SRAM memory with optional cache configuration and parity support. The device supports 32-bit, 40-bit, and 64-bit floating-point operations alongside 32-bit fixed-point processing. It is housed in a 176-lead LQFP_EP package.

• Support for 32-bit, 40-bit, and 64-bit floating-point and 32-bit fixed-point data formats
• 176-lead LQFP_EP package with RoHS compliance

Digital Signal Processor Dsp Applications

• High performance audio processing
• Floating-point signal processing applications
• Industrial control systems requiring high computational throughput

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix CSWZ-5 against the manufacturer's current ordering guide to confirm package type, temperature range, and revision level. Ensure compatibility with existing board layouts for the 176-lead LQFP_EP footprint. Check for any recent product change notices regarding assembly relocation or material composition updates.

Digital Signal Processor Dsp Selection Notes

Select this component when dual-core SHARC+ performance at 500 MHz is required within a 176-lead LQFP_EP form factor. Consider the ADSP-SC571 if an integrated Arm Cortex-A5 core is needed for system management tasks. Evaluate the L1 SRAM configuration needs, as the architecture allows flexible allocation between data, program memory, and instruction cache.

Digital Signal Processor Dsp Part Context

This part belongs to the ADSP-SC57x/ADSP-2157x family, which integrates industry-leading system peripherals and memory. The ADSP-21571 variant specifically excludes the Arm Cortex-A5 core found in the SC57x counterparts, focusing purely on the dual SHARC+ DSP architecture for dedicated signal processing workloads.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21571BSWZ-5 is a lower-speed variant operating at 450 MHz. The ADSP-21571KSWZ-5 may represent a different temperature grade or revision. Verify electrical specifications and pin compatibility before substitution.
