Overview

ADSP-SC572CBCZ-42 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 384 kB L1 SRAM per SHARC+ core (768 kB total), 256 kB L2 cache with parity, and 1 MB L2 SRAM with ECC - optimized for high-fidelity audio processing, automotive infotainment, and real-time industrial control systems.

For engineers reviewing the ADSP-SC572CBCZ-42 datasheet, ADSP-SC572CBCZ-42 pinout, ADSP-SC572CBCZ-42 application, or ADSP-SC572CBCZ-42 equivalent, key selection criteria include dual SHARC+ floating-point throughput, AEC-Q100 qualification, DDR3/DDR2/LPDDR1 memory controller support, dual CAN 2.0 interfaces, and hardware-accelerated FIR/IIR filtering - all in a 400-ball CSP_BGA package rated for automotive temperature range.

Technical Context

The ADSP-SC572CBCZ-42 implements a heterogeneous dual-processor architecture: one Arm Cortex-A5 core (500 MHz, NEON/VFPv4-D16, 32 kB I-cache/32 kB D-cache, 256 kB L2 cache) coexists with two SHARC+ cores (each 500 MHz, 32-/40-/64-bit floating-point, 384 kB L1 SRAM with parity). The system fabric interconnects them via shared L2 SRAM (1 MB with ECC), L3 DDR interface, and crossbar DMA subsystem.

It integrates safety-critical infrastructure including Arm TrustZone security, dual CRC engines, watchdog timers, thermal monitor unit (TMU), and system protection unit (SPU). Peripherals include 2× CAN2.0, 3× UART, 2× SPI + 1× Quad-SPI, 3× I²C, USB 2.0 HS, EMAC (10/100/1000), SDIO/eMMC, 8-channel 12-bit HADC, S/PDIF Rx/Tx, and 4× ASRCs - all mapped to a 400-ball CSP_BGA footprint with automotive-grade reliability.

Key Specifications

Pinout & Package

ADSP-SC572CBCZ-42 uses a 17 mm × 17 mm 400-ball CSP_BGA package (ball pitch: 0.65 mm), RoHS compliant, with exposed thermal pad. Pin assignments follow Analog Devices' standardized 400-ball CSP_BGA layout for the ADSP-SC57x family, supporting full GPIO multiplexing, differential clock inputs, DDR3 termination, and dedicated power/ground ball patterns per JEDEC MO-220.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-core DSP + application processor applications.

Compared with ADSP-SC573CBCZ-42, the ADSP-SC572CBCZ-42 omits USB PHY and gigabit EMAC to reduce cost and power - ideal for cost-sensitive automotive audio nodes. Versus i.MX 8M Plus, it delivers 3.2× higher sustained floating-point throughput per watt for audio filtering and eliminates software-based ASRC latency jitter.

ADSP-SC572CBCZ-42 is available at Aetrix Electronics and suitable for automotive infotainment, professional audio equipment, and industrial motor control applications requiring stable component supply, long-term lifecycle assurance, and AEC-Q100-compliant sourcing.

Supply support for ADSP-SC572CBCZ-42 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Analog Devices, Inc. is a global leader in high-performance analog, mixed-signal, and digital signal processing technologies, headquartered in Wilmington, MA, serving automotive, industrial, communications, and healthcare markets.

The ADSP-SC57x product line was designed specifically for high-fidelity, low-latency audio and real-time control applications where deterministic floating-point performance, hardware-accelerated signal processing, and automotive-grade reliability are mandatory - not general-purpose computing.

FAQ

What is the maximum operating frequency of each core in the ADSP-SC572CBCZ-42?

The ADSP-SC572CBCZ-42 operates at 500 MHz for both SHARC+ cores and the Arm Cortex-A5 core. This is confirmed in Table 2 of the Rev. C datasheet, which specifies "SHARC+ Core1 (MHz, Max): 450" for SC570 but "500" for SC572, and "Arm Cortex-A5 (MHz, Max): 500" across SC571/SC572/SC573 variants. The "-42" speed grade denotes guaranteed 500 MHz operation across automotive temperature range.

Does the ADSP-SC572CBCZ-42 support DDR3 memory, and what voltage does it require?

Yes, the ADSP-SC572CBCZ-42 supports DDR3L (1.5 V) memory via its 16-bit L3 interface, as stated in the "ADDITIONAL FEATURES" section and Table 2. It explicitly supports "DDR3 (supporting 1.5 V capable DDR3L devices), DDR2, or LPDDR1". The VDD_DDR supply must be regulated to 1.5 V ±3%, and the interface complies with JEDEC DDR3L standards for timing and termination.

How many CAN interfaces does the ADSP-SC572CBCZ-42 integrate, and are they CAN FD capable?

The ADSP-SC572CBCZ-42 integrates two CAN 2.0 controllers, as listed in the "PERIPHERALS" block diagram and Table 1. These are legacy CAN 2.0B controllers supporting up to 1 Mbps, not CAN FD - the datasheet makes no mention of CAN FD protocol support, bit rate switching, or ISO 11898-1:2015 compliance. For CAN FD, external transceivers or companion MCUs are required.

Is the ADSP-SC572CBCZ-42 qualified for automotive use, and what grade does it meet?

Yes, the ADSP-SC572CBCZ-42 is AEC-Q100 qualified for automotive applications, as explicitly stated in the "ADDITIONAL FEATURES" section. It meets Grade 2 requirements (−40°C to +105°C ambient operating temperature), validated per AEC-Q100-001 through -011 test standards - confirmed in the "Automotive Products" section (page 140) and ordering guide footnote.

What debug interfaces are available on the ADSP-SC572CBCZ-42, and can they access both processor cores simultaneously?

The ADSP-SC572CBCZ-42 provides IEEE 1149.1 JTAG (TDI/TDO/TCK/TMS) and Arm CoreSight debug infrastructure, enabling simultaneous multi-core debugging. The CoreSight Debug Unit (page 22) supports independent halt, step, and register access for Arm Cortex-A5 and both SHARC+ cores via standard JTAG or SWD, with full visibility into caches, MMU, and trace buffers as documented in the "System Debug" chapter.
