Product details
Overview
ADSP-SC571BSWZ-3 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. Designed for automotive audio processing, it integrates dual CAN 2.0 controllers, 3× UARTs, 2× SPI + quad-SPI, and AEC-Q100 qualification.
For engineers reviewing the ADSP-SC571BSWZ-3 datasheet, ADSP-SC571BSWZ-3 pinout, ADSP-SC571BSWZ-3 application, or ADSP-SC571BSWZ-3 equivalent, key selection criteria include dual SHARC+ core frequency (500 MHz), Arm Cortex-A5 clock (500 MHz), L1 SRAM configuration (2 × 384 kB), package type (176-lead LQFP_EP), and automotive-grade peripheral set including dual CAN 2.0 and HADC (8-channel, 12-bit).
Technical Context
The ADSP-SC571BSWZ-3 implements a heterogeneous dual-processor architecture: one Arm Cortex-A5 core handling high-level OS tasks and system control, and two SHARC+ cores optimized for deterministic real-time signal processing. Its memory subsystem includes tightly coupled L1 SRAM per SHARC+ core (384 kB each), shared 1 MB L2 SRAM with ECC, and 256 kB L2 cache with parity-enabling low-latency, high-bandwidth data movement between cores via system crossbar and DMA.
Peripherals are routed through a Signal Routing Unit (SRU) and multiplexed GPIO (Port A–D, 64 + 20 pins), supporting simultaneous use of 2× link ports, 4× full SPORTs, S/PDIF Rx/Tx, ASRCs (4 pairs), and precision clock generators. Safety and security are enforced via Arm TrustZone, dual CRC units, watchdog timers, thermal monitor unit (TMU), and cryptographic hardware accelerators for fast secure boot.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core DSP + application processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADSP-SC572BSWZ-3 | 400-ball CSP_BGA package; adds DDR3/DDR2/LPDDR1 controller and second link port; no USB 2.0 HS | Targeted at space-constrained designs requiring external DRAM and higher I/O bandwidth | Select when system requires >1 MB off-chip memory expansion and PCB layout allows BGA routing |
| ADSP-SC571WBCZ-3 | Same 176-LQFP_EP package but AEC-Q100 Grade 1 (−40°C to +125°C); identical core/peripheral specs | Required for engine bay or powertrain-adjacent audio preprocessing where ambient exceeds 105°C | Select only if extended temperature range is mandated by mechanical placement-not for general infotainment use |
Compared with ADSP-SC571BSWZ-3, ADSP-SC572BSWZ-3 trades USB 2.0 HS and LQFP manufacturability for DDR interface and BGA density, while ADSP-SC571WBCZ-3 maintains pin compatibility but raises thermal qualification ceiling-neither offers drop-in replacement without design review.

FAQ
What is the maximum operating frequency of each SHARC+ core in the ADSP-SC571BSWZ-3?
The ADSP-SC571BSWZ-3 operates each SHARC+ core at up to 500 MHz, as confirmed in Table 2 of the Rev. C datasheet. This frequency enables sustained floating-point performance exceeding 2000 MFLOPS per core, supporting real-time execution of complex audio algorithms such as 256-tap FIR filters or 1024-point FFTs at 96 kHz sample rates. The ADSP-SC571BSWZ-3 achieves this speed with on-die voltage regulation and thermal monitoring to maintain stability across the automotive temperature range.
Does the ADSP-SC571BSWZ-3 support external DDR memory?
No, the ADSP-SC571BSWZ-3 does not integrate a DDR memory controller. As shown in Table 2, DDR3/DDR2/LPDDR1 support is exclusive to the ADSP-SC572/SC573 variants. The ADSP-SC571BSWZ-3 relies solely on its on-chip memory resources: 2 × 384 kB L1 SRAM, 256 kB L2 cache, and 1 MB L2 SRAM with ECC. System designers must plan memory allocation accordingly-no external DRAM interface is available on this specific variant of the ADSP-SC571BSWZ-3.
What package type and thermal characteristics does the ADSP-SC571BSWZ-3 use?
The ADSP-SC571BSWZ-3 uses a 176-lead LQFP_EP (exposed pad) package measuring 24.0 mm × 24.0 mm with 1.0 mm lead pitch. It is rated for AEC-Q100 Grade 2 operation (−40°C to +105°C ambient), and its exposed pad must be soldered to a thermal pad on the PCB for effective heat dissipation. Thermal resistance (θJA) is 26.5°C/W under JEDEC JESD51-7 conditions, and the device includes an integrated Thermal Monitor Unit (TMU) for real-time junction temperature reporting-key for automotive thermal management compliance in the ADSP-SC571BSWZ-3.
How many CAN 2.0 interfaces does the ADSP-SC571BSWZ-3 provide, and are they fully independent?
The ADSP-SC571BSWZ-3 integrates two fully independent CAN 2.0B controllers (CAN0 and CAN1), each with dedicated TX/RX pins, message RAM, and filtering logic. Both support bit rates up to 1 Mbps, programmable timing quanta, and automatic retransmission. They operate concurrently without resource contention, enabling simultaneous communication with vehicle body control modules (via CAN0) and powertrain ECUs (via CAN1). This dual-CAN capability is explicitly listed in Table 1 and Figure 1 of the ADSP-SC571BSWZ-3 datasheet.
Is the ADSP-SC571BSWZ-3 pin-compatible with other members of the ADSP-SC57x family?
No, the ADSP-SC571BSWZ-3 is not pin-compatible with other ADSP-SC57x variants due to differing package types and peripheral allocations. While it shares the 176-lead LQFP_EP footprint with ADSP-SC570BSWZ-3, it lacks the USB 2.0 HS PHY and EMAC AVB support found in SC572/SC573 (which use 400-ball CSP_BGA). Pin mappings for GPIO, peripherals, and power are consistent within the LQFP group (SC570/SC571), but no cross-package pin compatibility exists. Always verify ball/lead assignments against the specific variant's signal description tables before PCB reuse.
