Product details
Overview
ADSP-SC571KSWZ-5 from Analog Devices is a dual-core SHARC+ DSP with integrated Arm Cortex-A5 processor, delivering 500 MHz per SHARC+ core and 500 MHz Arm Cortex-A5 operation. It features 2 × 384 kB L1 SRAM with parity, 256 kB L2 cache with parity, 1 MB L2 SRAM with ECC, and supports 32-/40-/64-bit floating-point arithmetic. It targets high-performance automotive audio processing systems requiring real-time signal co-processing and secure boot.
For engineers reviewing the ADSP-SC571KSWZ-5 datasheet, ADSP-SC571KSWZ-5 pinout, ADSP-SC571KSWZ-5 application, or ADSP-SC571KSWZ-5 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-5 implements a heterogeneous dual-processor architecture: one SHARC+ core running at up to 500 MHz (Core1), and an Arm Cortex-A5 core also at 500 MHz, both sharing a 256 kB L2 cache with parity and accessing 1 MB L2 SRAM with ECC. The system includes a dedicated L3 interface supporting DDR3L, DDR2, or LPDDR1 memory at 16-bit width.
It integrates hardware accelerators for FIR and IIR filtering, cryptographic engines for secure boot and IP protection, and Arm TrustZone for memory isolation. Peripherals include two CAN 2.0 controllers, three UARTs, three I²C interfaces, two SPI plus quad-SPI, USB 2.0 HS, EMAC (10/100 Mbps), and an 8-channel 12-bit HADC - all mapped to the 400-ball CSP_BGA package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar heterogeneous DSP+Arm applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADSP-SC572KSWZ-5 | Includes DDR3L controller and dual-link ports; same core speeds and memory but adds 16-bit external memory interface | Required for systems needing external SDRAM buffering (e.g., large FIR coefficient tables or video overlay buffers) | Select when external DDR bandwidth >200 MB/s is needed; ADSP-SC571KSWZ-5 lacks DDR controller |
| NXP i.MX 8M Plus | Quad Cortex-A53 + Cortex-M7 + NPU; no SHARC+ DSP; uses ARM NEON instead of native floating-point SIMD | Better suited for AI inference and GUI rendering, but lacks deterministic audio latency and 40-bit extended precision | Choose for vision+audio hybrid apps where ML inference dominates; ADSP-SC571KSWZ-5 preferred for pure audio DSP workloads |
Compared with ADSP-SC572KSWZ-5, the ADSP-SC571KSWZ-5 omits DDR3L support but retains identical SHARC+/Arm performance and AEC-Q100 qualification - making it optimal for cost-sensitive, self-contained audio systems.

FAQ
What is the maximum operating temperature specification for ADSP-SC571KSWZ-5?
The ADSP-SC571KSWZ-5 is AEC-Q100 Grade 2 qualified, rated for continuous operation from −40°C to +105°C ambient temperature. This specification is validated across voltage, frequency, and process corners, and applies to the full 500 MHz SHARC+ and Arm Cortex-A5 operation - making it suitable for under-dash automotive head units and industrial enclosures without forced cooling.
Does ADSP-SC571KSWZ-5 support secure boot with cryptographic verification?
Yes, ADSP-SC571KSWZ-5 includes a hardware cryptographic engine supporting AES-128, SHA-256, and RSA-2048 operations, enabling fast secure boot with IP protection. The boot ROM validates signed firmware images before execution, and TrustZone enforces isolation between secure and non-secure worlds - all confirmed in Analog Devices' ADSP-SC57x Hardware Reference Manual Rev. C, Section 13.
How many CAN 2.0 interfaces does ADSP-SC571KSWZ-5 provide, and are they isolated from other peripherals?
ADSP-SC571KSWZ-5 integrates two independent CAN 2.0 controllers (CAN0 and CAN1), each with dedicated message RAM, transmit/receive buffers, and bit-rate configuration registers. They operate autonomously from the SHARC+ and Arm cores via DMA and share no register space with UART or SPI peripherals - ensuring deterministic CAN frame handling even during heavy audio processing loads.
Can ADSP-SC571KSWZ-5 directly interface with DDR3L memory?
No, ADSP-SC571KSWZ-5 does not include a DDR3L memory controller. Unlike the ADSP-SC572/SC573 variants, this part relies solely on its 1 MB on-chip L2 SRAM with ECC and 16-bit L3 interface to external LPDDR1, DDR2, or DDR3L memory - meaning external DDR must be connected through a compatible memory controller IC or FPGA bridge, not directly.
What development tools are officially supported for ADSP-SC571KSWZ-5 firmware development?
Analog Devices officially supports CrossCore Embedded Studio (CCES) v2.12+ for ADSP-SC571KSWZ-5, including SHARC+ and Arm Cortex-A5 debug, profiling, and linker scripts. The EZ-KIT evaluation board (ADZS-SC571-EZLITE) provides JTAG/SWD debugging, USB-to-UART console, and reference schematics - all documented in the ADSP-SC57x Software Development Manual Rev. C.
