ADSP-SC570BSWZ-4

Digital Signal Processor Dsp Overview

The ADSP-SC570BSWZ-4 is a digital signal processor from Analog Devices, part of the SHARC+ family. It integrates a single-core SHARC+ processor and an Arm Cortex-A5 core within a 176-lead LQFP_EP package. The SHARC+ core operates at a maximum frequency of 450 MHz and includes 384 kB of L1 SRAM with parity support. The Arm Cortex-A5 core also runs at up to 450 MHz, featuring 32 kB instruction cache and 32 kB data cache. The device provides 1 MB of shared L2 SRAM with ECC protection. Key peripherals include a 10/100 Ethernet MAC (EMAC), USB 2.0 High-Speed interface, SDIO/eMMC controller, and multiple communication interfaces such as SPI, UART, I2C, and CAN 2.0.

Digital Signal Processor Dsp Feature Summary

• Dual-enhanced SHARC+ single-core DSP with up to 450 MHz operation and 384 kB L1 SRAM per core.
• Arm Cortex-A5 application processor with NEON/VFPv4-D16 support, 32 kB L1 I/D cache, and 256 kB L2 cache.
• Integrated security features including hardware cryptographic accelerators, secure boot, and Arm TrustZone support.
• Comprehensive peripheral set including 10/100 EMAC, USB 2.0 HS, SDIO/eMMC, and dual CAN 2.0 controllers.

Digital Signal Processor Dsp Applications

• Automotive infotainment and instrument cluster systems requiring AEC-Q100 qualification.
• Professional audio processing applications utilizing high-performance floating-point capabilities.
• Industrial control systems needing robust real-time signal processing and connectivity.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'B' in the part number against the official Analog Devices ordering guide to confirm package type and temperature range specifications. Ensure compatibility with the 176-lead LQFP_EP footprint during PCB layout. Check for RoHS compliance status in the latest datasheet revision. Confirm availability through authorized distributors as supply levels may vary.

Digital Signal Processor Dsp Selection Notes

Select this component when a single SHARC+ core combined with an Arm Cortex-A5 host is sufficient for the application workload. Compare against the ADSP-SC571 variant if dual SHARC+ cores are required for higher throughput. Consider the ADSP-SC572 or SC573 if Gigabit Ethernet or BGA packaging is necessary. Evaluate power consumption requirements across the specified operating temperature range.

Digital Signal Processor Dsp Part Context

This processor belongs to the ADSP-SC57x series, which shares architectural similarities with the ADSP-2157x family but includes the Arm Cortex-A5 core. It is designed for applications demanding both high-performance digital signal processing and complex system management. The device supports code compatibility with previous generation SHARC processors while offering enhanced cache and branch prediction features.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-SC570KSWZ-4 is a comparable single-core variant within the same family. For dual-core requirements, the ADSP-SC571BSWZ-4 offers two SHARC+ cores. If external memory interfaces like DDR3 are needed, consider the ADSP-SC572 or ADSP-SC573 models. Verify pinout and register compatibility before substituting.
