ADSP-SC571CSWZ-4

Digital Signal Processor Dsp Overview

The ADSP-SC571CSWZ-4 is a digital signal processor from Analog Devices, featuring a dual-core SHARC+ architecture and an Arm Cortex-A5 core. It operates at a maximum clock frequency of 500 MHz for both the SHARC+ cores and the Arm Cortex-A5. The device includes up to 3 MB (2 × 384 kB) of L1 SRAM per SHARC+ core with parity support and 256 kB 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 communication interfaces such as SPI, UART, I2C, and CAN 2.0. It is housed in a 176-lead LQFP_EP package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'CSWZ-4' against the official Analog Devices ordering guide to confirm package type, temperature range, and lead-free status. Ensure compatibility with existing board layouts for the 176-lead LQFP_EP footprint. Check for any recent revisions to the datasheet that may affect electrical characteristics or pin configurations.

Digital Signal Processor Dsp Selection Notes

Select this model when dual high-performance DSP cores are required alongside a general-purpose application processor. The 500 MHz speed grade is suitable for complex signal processing tasks. Consider the 176-lead LQFP_EP package if BGA options are not feasible for the assembly process. Verify peripheral requirements such as the need for 10/100 Ethernet versus 10/100/1000 capabilities found in other variants.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-SC57x family, which integrates SHARC+ and Arm Cortex-A5 cores. It is designed for applications requiring high floating-point performance and multimedia support. The SC571 variant specifically offers dual SHARC+ cores and a 500 MHz Arm Cortex-A5, distinguishing it from single-core or lower-speed variants in the series.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same package and feature set include the ADSP-SC571BSWZ-4 (lower speed grade) or ADSP-SC571ESWZ-4 (higher speed grade). For automotive applications, consider the ADSP-SC571WSWZ-4 variant. Ensure functional equivalence regarding peripheral availability and memory configuration.
