Product details
Overview
ADSP-21571BSWZ-5 from Analog Devices is a dual-core SHARC+ DSP with Arm Cortex-A5 co-processor in 176-lead LQFP_EP package, operating at 500 MHz per SHARC+ core and 500 MHz Arm Cortex-A5, featuring 3 Mb L1 SRAM (384 kB per core), 1 MB L2 SRAM with ECC, and dual CAN 2.0 interfaces - deployed in automotive audio domain controllers and real-time engine control units.
For engineers reviewing the ADSP-21571BSWZ-5 datasheet, ADSP-21571BSWZ-5 pinout, ADSP-21571BSWZ-5 application, or ADSP-21571BSWZ-5 equivalent, key selection criteria include SHARC+ floating-point throughput, Arm Cortex-A5 Linux-capable runtime, LQFP thermal performance, AEC-Q100 qualification, and dual-core deterministic interrupt latency under 100 ns.
Technical Context
The ADSP-21571BSWZ-5 integrates two SHARC+ SIMD cores with independent 384 kB L1 SRAM banks (parity-protected), each supporting 32-/40-/64-bit floating-point and 32-bit fixed-point arithmetic, plus an Arm Cortex-A5 core running at 500 MHz with 32 kB I-cache/32 kB D-cache (both parity-protected) and 256 kB L2 cache.
Its system infrastructure includes a shared 1 MB L2 SRAM with ECC, dual CAN 2.0 controllers, three UARTs, two SPIs + one Quad-SPI, three I²C interfaces, eight timers, and a 12-bit 8-channel HADC - all coordinated via a crossbar DMA subsystem and Signal Routing Unit (SRU) for low-latency inter-core data exchange.

FAQ
What is the maximum operating temperature rating for ADSP-21571BSWZ-5?
The ADSP-21571BSWZ-5 is AEC-Q100 Grade 2 qualified, rated for continuous operation from −40°C to +105°C ambient temperature. This specification is validated across all electrical parameters including core voltage regulation, CAN transceiver timing, and SRAM retention - making it suitable for under-dash automotive modules and industrial enclosures without forced cooling.
Does ADSP-21571BSWZ-5 support secure boot with cryptographic verification?
Yes, ADSP-21571BSWZ-5 implements fast secure boot using on-chip cryptographic accelerators and Arm TrustZone. During power-on reset, the device verifies SHA-256 hashes of boot images stored in OTP or external flash before loading executable code - ensuring firmware integrity and preventing unauthorized code execution in telematics and gateway applications.
Can ADSP-21571BSWZ-5 run a Linux OS on its Arm Cortex-A5 core?
Yes, the ADSP-21571BSWZ-5's 500 MHz Arm Cortex-A5 core with 32 kB I-cache, 32 kB D-cache, and 256 kB L2 cache fully supports lightweight Linux distributions such as Buildroot or Yocto Project. The 1 MB L2 SRAM with ECC serves as reliable RAM for kernel and rootfs, while the integrated EMAC and USB 2.0 HS enable network and peripheral connectivity without external controllers.
How many CAN interfaces does ADSP-21571BSWZ-5 provide, and are they isolated?
The ADSP-21571BSWZ-5 integrates two independent CAN 2.0 controllers (CAN0 and CAN1), each with dedicated TX/RX pins and full protocol handling - supporting bit rates up to 1 Mbps. Physical isolation requires external CAN transceivers (e.g., ADM3053); the IC itself provides only the controller logic and does not include galvanic isolation circuitry.
Is the L1 SRAM on ADSP-21571BSWZ-5 configurable as cache or only as SRAM?
The 3 Mb L1 memory (2 × 384 kB per SHARC+ core) on ADSP-21571BSWZ-5 is fully configurable: portions can be set as SRAM, instruction cache, or data cache - all with parity protection. Configuration is controlled via core memory-mapped registers (CMMRs) at runtime, allowing dynamic allocation based on algorithm needs - e.g., 256 kB SRAM + 128 kB I-cache per core.
