Analog Devices Inc. ADSP-SC571BSWZ-5

Overview

ADSP-SC571BSWZ-5 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 SHARC+ core), 256 kB L2 cache with parity, and supports 32-/40-/64-bit floating-point arithmetic. It targets high-performance automotive audio processing and real-time signal control systems requiring deterministic low-latency execution.

For engineers reviewing the ADSP-SC571BSWZ-5 datasheet, ADSP-SC571BSWZ-5 pinout, ADSP-SC571BSWZ-5 application, or ADSP-SC571BSWZ-5 equivalent, key selection criteria include dual-core SHARC+ clock speed, Arm Cortex-A5 integration, on-chip L2 SRAM with ECC, AEC-Q100 qualification, and 400-ball CSP_BGA package compatibility with DDR3L/DDR2/LPDDR1 memory interfaces.

Technical Context

The ADSP-SC571BSWZ-5 implements a heterogeneous dual-processor architecture: one SHARC+ core runs at 500 MHz with 384 kB L1 SRAM and full SIMD support, while the second SHARC+ core operates at 500 MHz with identical L1 SRAM and independent cache configuration. The Arm Cortex-A5 core runs concurrently at 500 MHz with 32 kB I-cache, 32 kB D-cache, and 256 kB L2 cache - all with parity protection.

Its system infrastructure includes a shared 1 MB L2 SRAM with ECC, a 16-bit L3 interface supporting DDR3L (1.5 V), DDR2, and LPDDR1, dual CAN 2.0 controllers, three UARTs, four full SPORTs, S/PDIF Rx/Tx, and hardware accelerators for FIR/IIR filtering. It integrates Arm TrustZone security, cryptographic engines, and AEC-Q100 qualification for automotive use.

FAQ

What is the maximum operating frequency of each SHARC+ core in the ADSP-SC571BSWZ-5?

The ADSP-SC571BSWZ-5 features two SHARC+ cores both rated for operation at up to 500 MHz. This frequency is guaranteed across the full industrial temperature range (−40°C to +105°C) and supported by on-chip voltage regulation and thermal monitoring circuitry. Each core maintains independent clock domains and can be operated at different frequencies if required by software configuration.

Does the ADSP-SC571BSWZ-5 support DDR3L memory, and what interface does it use?

Yes, the ADSP-SC571BSWZ-5 supports DDR3L memory through its 16-bit L3 memory interface. It is explicitly qualified for 1.5 V DDR3L devices, as well as DDR2 and LPDDR1. The interface includes dedicated command/address lines, 16 data lines with DQS strobes, and on-die termination control - all documented in the ADSP-SC571BSWZ-5 datasheet Section "L3 Memory Interface".

How many hardware-accelerated FIR/IIR engines does the ADSP-SC571BSWZ-5 include?

The ADSP-SC571BSWZ-5 includes dedicated hardware accelerators for both FIR and IIR filtering, as confirmed in the "Additional Features" section of its datasheet. These engines operate independently of the SHARC+ cores and can process filter coefficients stored in L1 SRAM, reducing core load by up to 90% for fixed-function filtering tasks commonly used in audio and sensor signal conditioning.

Is the ADSP-SC571BSWZ-5 AEC-Q100 qualified, and what grade does it meet?

Yes, the ADSP-SC571BSWZ-5 is AEC-Q100 qualified to Grade 2, meaning it is tested and certified for operation from −40°C to +105°C ambient temperature. This qualification covers HTOL, TC, ESD, and other stress tests defined in the AEC-Q100 standard, making it suitable for passenger compartment and front-end module applications in automotive systems.

What debug and trace capabilities are built into the ADSP-SC571BSWZ-5?

The ADSP-SC571BSWZ-5 integrates Arm CoreSight debug infrastructure, including an Embedded Trace Macrocell (ETM) interface for instruction trace, a Debug Unit supporting SWD/JTAG, and hardware watchpoints. Both SHARC+ and Arm Cortex-A5 cores support real-time tracing, non-intrusive breakpoints, and register visibility - enabling full-system visibility during development of complex mixed-mode applications.
