Product details
Overview
ADSP-SC571CSWZ-4 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 dual CAN 2.0 interfaces - designed for real-time audio processing, automotive infotainment, and industrial control systems requiring deterministic floating-point performance.
For engineers reviewing the ADSP-SC571CSWZ-4 datasheet, ADSP-SC571CSWZ-4 pinout, ADSP-SC571CSWZ-4 application, or ADSP-SC571CSWZ-4 equivalent, key selection criteria include SHARC+ core clock speed, L1 SRAM configuration, Arm Cortex-A5 cache hierarchy, automotive AEC-Q100 qualification, and 400-ball CSP_BGA package compatibility with DDR3L/DDR2/LPDDR1 memory interfaces.
Technical Context
The ADSP-SC571CSWZ-4 implements a heterogeneous dual-domain architecture: one SHARC+ core (500 MHz) and one Arm Cortex-A5 core (500 MHz), each with independent L1 instruction/data caches (32 kB I-cache + 32 kB D-cache, parity-protected) and shared 256 kB L2 cache (parity-protected). The SHARC+ domain supports 32-/40-/64-bit floating-point and 32-bit fixed-point SIMD execution with zero-overhead circular buffers and DAG-based addressing.
System-level integration includes a 16-bit L3 interface supporting DDR3L (1.5 V), DDR2, and LPDDR1 SDRAM; hardware accelerators for FIR/IIR filtering; cryptographic engines with Arm TrustZone support; and safety features including dual CRC, watchdog timers, and thermal monitoring unit (TMU). It is AEC-Q100 qualified for automotive applications.

FAQ
What is the maximum operating frequency of the SHARC+ core in ADSP-SC571CSWZ-4?
The SHARC+ core in ADSP-SC571CSWZ-4 operates at a maximum frequency of 500 MHz. This rating is guaranteed across the full automotive temperature range (−40°C to +105°C) and is validated per AEC-Q100 stress testing protocols. The ADSP-SC571CSWZ-4 datasheet specifies this value in Table 2 under "SHARC+ Core1 (MHz, Max)" and confirms it applies to the SC571 variant specifically.
Does ADSP-SC571CSWZ-4 support DDR3L memory?
Yes, ADSP-SC571CSWZ-4 supports DDR3L memory through its 16-bit L3 interface. The datasheet explicitly states compatibility with "1.5 V capable DDR3L devices" alongside DDR2 and LPDDR1. This support is implemented in the memory controller block and requires proper VDDQ termination and timing calibration per JEDEC JESD79-3F specification.
How many CAN 2.0 interfaces does ADSP-SC571CSWZ-4 integrate?
ADSP-SC571CSWZ-4 integrates two CAN 2.0 controllers (CAN0 and CAN1), each with dedicated TX/RX pins and full protocol stack support including message buffering, acceptance filtering, and error confinement. This is confirmed in Table 1 ("Common Product Features") and Figure 1's peripheral block diagram - and distinguishes ADSP-SC571CSWZ-4 from SC570 variants which omit the second CAN interface.
Is ADSP-SC571CSWZ-4 pin-compatible with other ADSP-SC57x packages?
No, ADSP-SC571CSWZ-4 is not pin-compatible with LQFP-packaged variants like ADSP-SC571KSWZ-4. It uses a 400-ball CSP_BGA package (17 mm × 17 mm, 0.65 mm pitch), whereas LQFP variants use 176-lead exposed pad packages with entirely different ball/lead assignments and signal multiplexing. Pin compatibility exists only within the same package family - e.g., ADSP-SC572CSWZ-4 shares the same 400-ball footprint.
What boot sources are supported by ADSP-SC571CSWZ-4?
ADSP-SC571CSWZ-4 supports multiple boot sources determined by BOOT_CFG[3:0] strap pins: SPI flash, SDIO/eMMC, parallel NOR/NAND flash, and USB device mode. The boot ROM initializes the Arm Cortex-A5 first, then configures SHARC+ cores - with secure boot options enabled via OTP fuses. This configuration flexibility is documented in the "Boot Configuration" section of the ADSP-SC57x datasheet Rev. C.
