ADSP-21571CSWZ-4

Digital Signal Processor Dsp Overview

The ADSP-21571CSWZ-4 is a dual-enhanced SHARC+ high-performance floating-point digital signal processor from Analog Devices. It features two SHARC+ cores operating at up to 500 MHz, providing robust signal processing capabilities. The device integrates 3 Mb of L1 SRAM per core with parity support and 1 MB of shared L2 SRAM with ECC protection. It supports 32-bit, 40-bit, and 64-bit floating-point operations alongside 32-bit fixed-point processing. The processor is housed in a 176-lead LQFP_EP package, designed for applications requiring high computational throughput and low latency.

Digital Signal Processor Dsp Feature Summary

• 3 Mb (384 kB) L1 SRAM per core with configurable cache options
• 1 MB shared L2 SRAM with ECC protection
• Support for 32/40/64-bit floating-point and 32-bit fixed-point data formats

Digital Signal Processor Dsp Applications

• Automotive systems requiring AEC-Q100 qualified components
• Professional audio processing applications
• Industrial control systems demanding high floating-point performance

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix CSWZ-4 against the manufacturer's ordering guide to confirm package type, temperature range, and revision level. Ensure compatibility with existing board layouts for the 176-lead LQFP_EP footprint. Confirm that the design supports the required power supply voltages and clock configurations specified in the electrical characteristics section of the datasheet.

Digital Signal Processor Dsp Selection Notes

Select this component when dual-core SHARC+ processing is required without an integrated Arm Cortex-A5 core, distinguishing it from the SC57x series. Consider the 176-lead LQFP_EP package for surface-mount assembly constraints. Evaluate the 500 MHz maximum clock speed against application latency requirements. Verify that the 1 MB L2 SRAM meets memory capacity needs before considering external memory interfaces.

Digital Signal Processor Dsp Part Context

The ADSP-21571 belongs to the SHARC family of digital signal processors, specifically utilizing the Super Harvard Architecture. It is part of the ADSP-SC57x/ADSP-2157x product line, where the ADSP-2157x variants focus on DSP functionality without the embedded Arm Cortex-A5 processor found in the SC57x counterparts. This architecture ensures code compatibility with previous generation SHARC processors while offering enhanced SIMD capabilities.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21573 serves as a pin-compatible alternative within the same package if different peripheral availability is needed. For single-core requirements, the ADSP-2156x series may be considered, though architectural differences exist. Direct replacement requires verification of software compatibility and peripheral mapping.
