Analog Devices Inc. ADSP-SC572KBCZ-4

Overview

ADSP-SC572KBCZ-4 from Analog Devices is a dual-core SHARC+ DSP with integrated Arm Cortex-A5 processor in 400-ball CSP_BGA package, operating at up to 500 MHz per SHARC+ core and 500 MHz for the Arm core. It delivers 800 DMIPS, features 3 MB L1 SRAM (384 kB per SHARC+ core), 256 kB L2 cache with parity, and supports 32-/40-/64-bit floating-point arithmetic. It targets high-performance automotive audio processing systems requiring real-time signal path isolation and deterministic latency.

For engineers reviewing the ADSP-SC572KBCZ-4 datasheet, ADSP-SC572KBCZ-4 pinout, ADSP-SC572KBCZ-4 application, or ADSP-SC572KBCZ-4 equivalent, key selection criteria include dual-core SHARC+ clock speed, L1 SRAM partitioning, DDR3L interface capability, AEC-Q100 qualification, and 2× CAN2.0 + USB 2.0 HS peripheral integration for automotive infotainment and ADAS domain controllers.

Technical Context

The ADSP-SC572KBCZ-4 implements a heterogeneous dual-domain architecture: one Arm Cortex-A5 core handles Linux-based application layer tasks (e.g., GUI, network stack), while two SHARC+ cores execute time-critical, low-latency DSP algorithms (e.g., FIR/IIR filtering, ASRC, beamforming) with dedicated L1 memory and zero-overhead circular buffers. The system fabric interconnects both domains via shared L2 SRAM (1 MB with ECC) and a unified DMA subsystem supporting concurrent transfers across 3× I²C, 2× SPI, 3× UART, and 2× CAN2.0 interfaces.

Its safety and security context includes Arm TrustZone for secure world/normal world isolation, hardware cryptographic accelerators (AES/SHA/RSA), fast secure boot with OTP protection, and dual CRC engines. It is AEC-Q100 Grade 2 qualified (−40°C to +105°C), with thermal monitoring unit (TMU), watchdog timers, and system protection unit (SPU) enabling functional safety compliance in automotive ECUs.

Key Specifications

Pinout & Package

ADSP-SC572KBCZ-4 uses a 400-ball CSP_BGA package (17 mm × 17 mm, 0.65 mm pitch) with ball assignments defined in Analog Devices Document Rev. C, pages 127–133. Pin functions are multiplexed across GPIO ports A–F and DAI pins (92 + 20 total). Key terminal groups include VDD_CORE/VDD_IO power domains, differential clocks (CLKIN/CLKOUT), JTAG debug (TCK/TMS/TDI/TDO/TRST), and high-speed serial interfaces (USB_DP/DM, CAN_H/L, DDR_DQ[15:0], DDR_A[14:0], DDR_BA[2:0]).

FAQ

What is the maximum operating frequency of each core in the ADSP-SC572KBCZ-4?

The ADSP-SC572KBCZ-4 operates its dual SHARC+ cores at up to 500 MHz each and its Arm Cortex-A5 core at up to 500 MHz. This is confirmed in Table 2 of the Rev. C datasheet, which specifies "SHARC+ Core1 (MHz, Max): 450" for SC570 but "500" for ADSP-SC572KBCZ-4, and "Arm Cortex-A5 (MHz, Max): 500" for SC572. These frequencies are achievable under specified thermal and voltage conditions.

Does the ADSP-SC572KBCZ-4 support DDR3L memory, and what voltage does it require?

Yes, the ADSP-SC572KBCZ-4 supports DDR3L memory via its 16-bit L3 interface, specifically designed for 1.5 V capable DDR3L devices. The datasheet states "L3 interface optimized for low system power, providing 16-bit interface to DDR3 (supporting 1.5 V capable DDR3L devices), DDR2, or LPDDR1 SDRAM devices." This allows compatibility with low-voltage DDR3L modules while maintaining signal integrity at 533 MHz data rates.

How many CAN interfaces does the ADSP-SC572KBCZ-4 include, and are they CAN FD-capable?

The ADSP-SC572KBCZ-4 includes two CAN2.0 interfaces, as listed in the "PERIPHERALS" section and Table 1 ("CAN2.0: 2"). The documentation explicitly references "CAN2.0", not CAN FD, and no CAN FD registers, bit-rate switching support, or FD-specific timing parameters appear in the signal descriptions or register maps. Therefore, ADSP-SC572KBCZ-4 supports Classical CAN only, up to 1 Mbps.

Is the ADSP-SC572KBCZ-4 pin-compatible with other members of the ADSP-SC57x family?

No, ADSP-SC572KBCZ-4 is not universally pin-compatible across the ADSP-SC57x family. It shares the 400-ball CSP_BGA package with ADSP-SC573 and ADSP-21573, but differs from ADSP-SC570/SC571 (176-LQFP) and ADSP-21571 (176-LQFP). Even among BGA variants, pin functions vary-for example, USB and SDIO signals present on SC573 are NC on ADSP-SC572KBCZ-4-requiring board-level validation per the specific ball assignment tables.

What security features are implemented in the ADSP-SC572KBCZ-4 for firmware protection?

The ADSP-SC572KBCZ-4 implements cryptographic hardware accelerators (AES/SHA/RSA), fast secure boot with IP protection via OTP memory, and Arm TrustZone for hardware-enforced isolation between secure and normal worlds. These features are documented in the "Security and Protection" section and "Security Features" chapter. TrustZone enables secure firmware execution, while OTP prevents unauthorized firmware extraction, making ADSP-SC572KBCZ-4 suitable for automotive telematics with over-the-air update security requirements.
