ADSP-SC570KSWZ-4

Digital Signal Processor Dsp Overview

The ADSP-SC570KSWZ-4 is a single-core SHARC+ digital signal processor integrated with an Arm Cortex-A5 core, manufactured by Analog Devices. It operates at a maximum clock frequency of 450 MHz for both cores and utilizes a 176-lead LQFP_EP package. The device features 384 kB of L1 SRAM per SHARC+ core and 1 MB of shared L2 SRAM with ECC protection. Key peripherals include a 10/100 Ethernet MAC, USB 2.0 High-Speed interface, SDIO/eMMC controller, and multiple serial communication interfaces such as SPI, UART, I2C, and CAN 2.0. Designed for automotive applications, it supports AEC-Q100 standards and includes hardware security accelerators.

Digital Signal Processor Dsp Feature Summary

• Dual-enhanced SHARC+ single-core architecture with up to 450 MHz operation
• Integrated Arm Cortex-A5 core with NEON/VFPv4-D16 support
• 1 MB shared L2 SRAM with ECC and 384 kB L1 SRAM per SHARC+ core
• Automotive-grade qualification (AEC-Q100) with extended temperature range

Digital Signal Processor Dsp Applications

• Automotive infotainment systems
• Professional audio processing
• Industrial control systems requiring high floating-point performance

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'KSWZ-4' against the manufacturer's current ordering guide to confirm package type, temperature grade, and revision level. Ensure compatibility with development tools such as CrossCore Embedded Studio or SigmaStudio for SHARC when designing firmware. Check for RoHS compliance documentation if required for your manufacturing process.

Digital Signal Processor Dsp Selection Notes

Select this model when a single SHARC+ core is sufficient for the signal processing load, reducing complexity compared to dual-core variants like the SC571. The 450 MHz speed grade offers a balance between performance and power consumption. Consider the 176-lead LQFP package for easier PCB layout if BGA routing is constrained, while ensuring the design accommodates the 1.1 V core voltage requirement.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-SC57x family, which integrates SHARC+ DSPs with Arm Cortex-A5 processors. It is part of the broader SHARC portfolio, maintaining assembly-level code compatibility with previous generations like the ADSP-214xx series. The SC570 variant specifically provides a single SHARC+ core, distinguishing it from the dual-core SC571 and other members of the SC57x/ADSP-2157x lineup.

Digital Signal Processor Dsp Replacement Considerations

For direct functional replacements within the same package and pinout, consider the ADSP-SC570BSWZ-4 or ADSP-SC570ASWZ-4, noting that suffix changes may indicate different speed grades or temperature ranges. Verify memory configuration and peripheral availability against the datasheet comparison tables before substituting.
