Product details
Overview
ADSP-SC571KSWZ-4 from Analog Devices is a dual-core SHARC+ DSP with integrated Arm Cortex-A5 processor, operating at 500 MHz per SHARC+ core and 500 MHz for the Arm core. It delivers 800 DMIPS, features 3 MB L1 SRAM (384 kB per core), 256 kB L2 cache with parity, and supports 32-/40-/64-bit floating-point arithmetic. It targets high-performance automotive audio processing systems requiring deterministic real-time signal handling and secure application execution.
For engineers reviewing the ADSP-SC571KSWZ-4 datasheet, ADSP-SC571KSWZ-4 pinout, ADSP-SC571KSWZ-4 application, or ADSP-SC571KSWZ-4 equivalent, key selection criteria include dual-core SHARC+ clock speed, Arm Cortex-A5 integration, AEC-Q100 qualification, 400-ball CSP_BGA package compatibility, and support for FIR/IIR offload engines and TrustZone security.
Technical Context
The ADSP-SC571KSWZ-4 implements a heterogeneous dual-processor architecture: one SHARC+ core running at 500 MHz and one Arm Cortex-A5 core also at 500 MHz, sharing a 1 MB L2 SRAM with ECC protection and connected via a system crossbar with DMA subsystem. It includes two independent L1 memory spaces (384 kB each) with configurable SRAM/cache mapping and parity protection.
Peripherals include dual CAN 2.0 controllers, three UARTs, three I²C interfaces, two SPI plus one quad-SPI, two link ports, S/PDIF Rx/Tx, four ASRCs, two precision clock generators, and an 8-channel 12-bit HADC - all accessible through a programmable Signal Routing Unit (SRU) and supported by hardware accelerators for FIR/IIR filtering and cryptographic operations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar heterogeneous DSP + application processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADSP-SC572KSWZ-4 | Includes DDR3/DDR2/LPDDR1 memory controller and dual link ports; same 400-ball CSP_BGA package | Required when external DDR memory or high-speed inter-processor links are needed beyond on-chip L2 SRAM | Select ADSP-SC572KSWZ-4 if system design mandates external memory expansion or deterministic inter-core communication over link ports |
| NXP i.MX 8M Plus | Quad Cortex-A53 + Cortex-M7 + NPU; no SHARC+ DSP; uses 2 GB LPDDR4, not SRAM-centric architecture | Better suited for vision-AI workloads than audio DSP; lacks native ASRC, S/PDIF, or HADC peripherals | Choose i.MX 8M Plus only when AI inference dominates over real-time audio processing; ADSP-SC571KSWZ-4 remains superior for latency-critical audio pipelines |
Compared with ADSP-SC572KSWZ-4, ADSP-SC571KSWZ-4 trades external memory support for lower power and smaller BOM; versus i.MX 8M Plus, it offers deterministic audio latency and integrated analog interfaces but no NPU - making it optimal for audio-first automotive ECU designs.

FAQ
What is the maximum operating temperature range for the ADSP-SC571KSWZ-4?
The ADSP-SC571KSWZ-4 is AEC-Q100 qualified for Grade 2 operation, supporting continuous operation from −40°C to +105°C ambient temperature. This rating applies to the full 400-ball CSP_BGA package and is validated across all core and peripheral functions, including SHARC+, Arm Cortex-A5, L1/L2 memory, and HADC modules - making it suitable for under-dash and center-console automotive deployments.
Does the ADSP-SC571KSWZ-4 include on-chip flash memory for program storage?
No, the ADSP-SC571KSWZ-4 does not integrate on-chip flash memory. It relies on external non-volatile storage such as SPI flash, NAND flash, or SDIO/eMMC for boot code and application images. Boot configuration pins (BOOT_CFG[3:0]) determine the primary boot source at power-up, and the device supports fast secure boot with cryptographic verification of externally loaded firmware - ensuring IP protection without embedded flash.
How many CAN 2.0 interfaces does the ADSP-SC571KSWZ-4 support, and are they isolated?
The ADSP-SC571KSWZ-4 integrates two fully compliant CAN 2.0B controllers (CAN0 and CAN1) with bit rates up to 1 Mbps. These are controller-only interfaces - physical layer transceivers must be added externally. Each controller supports message objects, FIFO buffers, and error counters, and both are accessible via the SRU for flexible pin multiplexing. No galvanic isolation is provided on-die; external isolated transceivers (e.g., ADM3053) are required for high-noise automotive bus environments.
Can the SHARC+ and Arm cores in the ADSP-SC571KSWZ-4 share memory coherently?
Yes, the ADSP-SC571KSWZ-4 implements hardware cache coherency between the SHARC+ and Arm Cortex-A5 cores using a shared L2 cache controller (PL310) and system fabric. The L2 cache supports snoop-based coherency protocols, and memory-mapped regions can be configured for coherent access. Software must use appropriate barrier instructions (e.g., DMB, DSBC) and cache maintenance operations (clean/invalidate) when sharing data - but no software-managed cache coherency protocol is required for standard L2-resident buffers.
Is the ADSP-SC571KSWZ-4 pin-compatible with other ADSP-SC57x variants like the ADSP-SC570 or ADSP-SC572?
No, the ADSP-SC571KSWZ-4 is not pin-compatible with ADSP-SC570 or ADSP-SC572. While all three use the same 400-ball CSP_BGA footprint, ball assignments differ significantly - particularly for memory interfaces (DDR signals present only on SC572/SC573), link ports (only SC572/SC573), and peripheral multiplexing. The ADSP-SC571KSWZ-4 shares identical pinout with ADSP-SC571W variants (automotive grade), but not with SC570 or SC572. PCB layout must be specific to ADSP-SC571KSWZ-4.
