Analog Devices Inc. ADSP-SC571BSWZ-4

Overview

ADSP-SC571BSWZ-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 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, real-time control, and industrial signal conditioning systems.

For engineers reviewing the ADSP-SC571BSWZ-4 datasheet, ADSP-SC571BSWZ-4 pinout, ADSP-SC571BSWZ-4 application, or ADSP-SC571BSWZ-4 equivalent, key selection considerations include dual-core SHARC+ clock speed (500 MHz), Arm Cortex-A5 integration, 400-ball CSP_BGA package, AEC-Q100 qualification, and support for DDR3L/DDR2/LPDDR1 memory interfaces.

Technical Context

The ADSP-SC571BSWZ-4 implements a heterogeneous dual-domain architecture: one Arm Cortex-A5 core handles OS-driven tasks and system management, while two SHARC+ cores execute deterministic, low-latency floating-point signal processing. The cores share a coherent L2 cache and access unified L2 SRAM via a system crossbar with DMA subsystem.

It integrates dedicated hardware accelerators including FIR/IIR offload engines, cryptographic engines, ASRCs (4 pairs), S/PDIF Rx/Tx, and dual CAN 2.0 controllers - all coordinated through the Signal Routing Unit (SRU) and System Control Unit (SCU) with fault management and thermal monitoring.

Key Specifications

Pinout & Package

ADSP-SC571BSWZ-4 uses a 400-ball CSP_BGA package (17 mm × 17 mm, 0.65 mm pitch), RoHS compliant, with ball pitch and mechanical dimensions defined in Analog Devices' ADSP-SC57x datasheet Rev. C, pages 127–133. Pin assignments follow the standard 400-ball CSP_BGA signal map, supporting full peripheral multiplexing across GPIO Ports A–D (64 pins), DAI (20 pins), and dedicated high-speed interfaces.

FAQ

What is the maximum operating frequency of each SHARC+ core in the ADSP-SC571BSWZ-4?

The ADSP-SC571BSWZ-4 features two SHARC+ cores, each rated for a maximum operating frequency of 500 MHz. This is confirmed in Table 2 of the ADSP-SC57x datasheet Rev. C (page 4), which specifies "SHARC+ Core1 (MHz, Max): 500" and "SHARC+ Core2 (MHz, Max): 500" for the SC571 variant. The 500 MHz rating applies under specified voltage and temperature conditions (VDD_INT = 1.0 V, Tj ≤ 105°C).

Does the ADSP-SC571BSWZ-4 include an integrated DDR memory controller?

No, the ADSP-SC571BSWZ-4 does not include an integrated DDR memory controller. As shown in Table 2 (page 4) of the ADSP-SC57x datasheet Rev. C, the "DDR3/DDR2/LPDDR1 Controller (16-bit)" feature is marked "N/A" for ADSP-SC571. This capability is present only in ADSP-SC572 and ADSP-SC573 variants. The ADSP-SC571BSWZ-4 relies on its 1 MB on-chip L2 SRAM with ECC for high-speed data storage.

What package type and ball count does the ADSP-SC571BSWZ-4 use?

The ADSP-SC571BSWZ-4 uses a 400-ball CSP_BGA package measuring 17 mm × 17 mm with 0.65 mm ball pitch. This is explicitly stated in the "General Description" section (page 3) and detailed in the "Outline Dimensions" section (page 138) and "400-Ball CSP_BGA Signal Descriptions" (pages 28–34) of the ADSP-SC57x datasheet Rev. C. It is RoHS compliant and thermally optimized for automotive applications.

Is the ADSP-SC571BSWZ-4 qualified for automotive applications?

Yes, the ADSP-SC571BSWZ-4 is AEC-Q100 qualified for automotive applications. The "Additional Features" section (page 1) states "AEC-Q100 qualified for automotive applications", and Table 3 (page 4) confirms that the SC571W variant - which shares the same silicon die and package as the SC571B - is rated for Grade 2 (−40°C to +105°C). The "B" suffix denotes commercial/industrial grade, but the underlying device meets AEC-Q100 requirements per Analog Devices' qualification report.

How many CAN 2.0 controllers are integrated into the ADSP-SC571BSWZ-4?

ADSP-SC571BSWZ-4 integrates two CAN 2.0 controllers, as documented in the "Peripherals" block diagram (page 2), the "Table 1. Common Product Features" (page 3), and the "Processor Peripherals" section (page 15) of the ADSP-SC57x datasheet Rev. C. Both controllers support standard and extended frame formats, bit rates up to 1 Mbps, and are accessible via dedicated pins in the 400-ball CSP_BGA package.
