ADSP-SC571KSWZ-3

Digital Signal Processor Dsp Overview

The ADSP-SC571KSWZ-3 is a digital signal processor featuring dual-enhanced SHARC+ floating-point cores and an Arm Cortex-A5 core, operating at up to 500 MHz. It utilizes the Analog Devices Super Harvard Architecture with up to 3 Mb (384 kB) L1 SRAM per SHARC+ core and 256 kB shared L2 SRAM with ECC protection. The device includes a 16-bit L3 interface for DDR3/DDR2/LPDDR1 SDRAM, integrated cryptographic accelerators, and supports automotive applications via AEC-Q100 qualification. It is housed in a 176-lead LQFP_EP package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix KSWZ-3 against the manufacturer's current ordering guide to confirm package type, temperature range, and RoHS compliance status. Ensure compatibility with existing PCB footprints for the 176-lead LQFP_EP package before integration.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high-performance floating-point DSP capabilities alongside a RISC control core in an automotive-grade environment. Compare memory configurations and peripheral availability against the ADSP-SC570 or ADSP-SC572 if different clock speeds or package options are required.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-SC57x family, which integrates SHARC+ DSPs with Arm Cortex-A5 processors. It shares architectural similarities with the ADSP-2157x series but offers distinct peripheral sets and performance profiles tailored for mixed-signal processing tasks.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible replacements within the same package include other variants from the ADSP-SC57x family such as the ADSP-SC570 or ADSP-SC572, provided their clock speeds and peripheral configurations meet system requirements.
