ADSP-SC571KSWZ-5

Digital Signal Processor Dsp Overview

The ADSP-SC571KSWZ-5 is a digital signal processor featuring dual enhanced SHARC+ cores and an Arm Cortex-A5 core, operating at a maximum frequency of 500 MHz. It integrates up to 3 MB of L1 SRAM per SHARC+ core with parity support and 1 MB of shared L2 SRAM with ECC protection. The device includes a 16-bit DDR controller supporting DDR3/DDR2/LPDDR1, USB 2.0 High-Speed, and an Ethernet MAC. Packaged in a 176-lead LQFP_EP, it supports fixed and floating-point arithmetic formats.

Digital Signal Processor Dsp Feature Summary

• Dual-enhanced SHARC+ SIMD cores with up to 3 MB L1 SRAM each

• Integrated 16-bit memory interface for DDR3, DDR2, or LPDDR1
• Peripheral set including USB 2.0 HS, EMAC, CAN 2.0, and Quad SPI

Digital Signal Processor Dsp Applications

• Automotive infotainment systems
• Professional audio processing
• Industrial control applications

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'KSWZ' against the manufacturer's official ordering guide to confirm package type, temperature range, and RoHS compliance status prior to procurement. Ensure design-in documentation matches the Rev. C datasheet specifications.

Digital Signal Processor Dsp Selection Notes

Select this model when dual high-performance DSP cores are required alongside an application processor. The 176-lead LQFP_EP package is suitable for designs requiring extensive GPIO multiplexing without the footprint constraints of the BGA option.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-SC57x family, which shares architectural features with the ADSP-2157x series. It is code-compatible with previous generation SHARC processors, facilitating migration from legacy single-core or earlier dual-core designs.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-SC570KSWZ-5 offers identical architecture but operates at a reduced maximum frequency of 450 MHz. The ADSP-SC572KSWZ-5 provides additional peripherals such as SDIO/eMMC and Gigabit Ethernet.
