Product details
Overview
ADSP-SC570BSWZ-4 from Analog Devices is a dual-core SHARC+ DSP with integrated Arm Cortex-A5 processor, delivering 450 MHz SHARC+ core performance and 450 MHz Arm Cortex-A5 operation. It features 384 kB L1 SRAM per SHARC+ core, 256 kB L2 cache, and supports 32-/40-/64-bit floating-point arithmetic. Designed for automotive audio processing, it integrates dual CAN 2.0 controllers, 3 UARTs, and 8-channel 12-bit HADC.
For engineers reviewing the ADSP-SC570BSWZ-4 datasheet, ADSP-SC570BSWZ-4 pinout, ADSP-SC570BSWZ-4 application, or ADSP-SC570BSWZ-4 equivalent, key selection criteria include SHARC+ core clock speed (450 MHz), Arm Cortex-A5 frequency (450 MHz), L1 SRAM configuration (1 × 384 kB), package type (176-lead LQFP_EP), and AEC-Q100 qualification for automotive use.
Technical Context
The ADSP-SC570BSWZ-4 implements a heterogeneous dual-processor architecture: one SHARC+ core running at up to 450 MHz and one Arm Cortex-A5 core also at 450 MHz, both sharing a unified system fabric with L2 SRAM (1 MB) protected by ECC. Its memory subsystem includes configurable L1 SRAM (384 kB per SHARC+ core) with parity and optional cache mapping, plus 32 kB L1 instruction and data caches for the Arm core.
Peripherals are routed via a Signal Routing Unit (SRU) and System Crossbar, enabling concurrent access to dual CAN 2.0 interfaces, three I²C controllers, two SPI ports plus quad-SPI, USB 2.0 HS, EMAC (10/100 Mbps), and 8-channel 12-bit HADC. Security is enforced through Arm TrustZone, cryptographic hardware accelerators, and fast secure boot with OTP memory.

FAQ
What is the maximum operating frequency of the SHARC+ core in ADSP-SC570BSWZ-4?
The SHARC+ core in ADSP-SC570BSWZ-4 operates at a maximum frequency of 450 MHz. This rating is specified under validated automotive operating conditions (−40°C to +105°C) and is guaranteed across voltage and process corners. The ADSP-SC570BSWZ-4 does not support dynamic frequency scaling; the core runs at fixed 450 MHz when enabled. This frequency enables deterministic execution of audio and control algorithms with cycle-accurate timing.
Does ADSP-SC570BSWZ-4 support DDR memory interfaces?
No, ADSP-SC570BSWZ-4 does not include a DDR memory controller. According to the official Analog Devices ordering guide and feature comparison tables, DDR3/DDR2/LPDDR1 support is explicitly disabled for the ADSP-SC570 and ADSP-SC571 variants. The ADSP-SC570BSWZ-4 relies solely on its 1 MB on-chip L2 SRAM with ECC and external parallel NOR/SPI flash for code storage. DDR capability is only present in ADSP-SC572/SC573 and ADSP-21573 variants.
What package type and thermal characteristics does ADSP-SC570BSWZ-4 use?
ADSP-SC570BSWZ-4 uses a 176-lead LQFP_EP (exposed pad) package with 0.5 mm pitch and 24 mm × 24 mm body size. The exposed thermal pad enhances heat dissipation, achieving a junction-to-board thermal resistance (ψJB) of 5.2°C/W and junction-to-case (ψJC) of 2.8°C/W. It is rated for AEC-Q100 Grade 2 operation (−40°C to +105°C), making it suitable for dashboard-mounted automotive electronics where airflow is limited.
How many CAN interfaces does ADSP-SC570BSWZ-4 integrate, and what protocol versions are supported?
ADSP-SC570BSWZ-4 integrates two independent CAN 2.0 controllers compliant with ISO 11898-1:2015. Both controllers support standard (11-bit) and extended (29-bit) identifier formats, bit rates up to 1 Mbps, and hardware message filtering. While CAN FD frame format is not natively supported in silicon, firmware-level arbitration and payload segmentation can implement FD-like behavior over standard CAN 2.0 - however, true CAN FD requires external transceivers and is not guaranteed by the ADSP-SC570BSWZ-4 specification.
Is ADSP-SC570BSWZ-4 pin-compatible with other ADSP-SC57x family members in the same package?
No, ADSP-SC570BSWZ-4 is not fully pin-compatible with other ADSP-SC57x variants in the 176-lead LQFP_EP package. Although mechanical footprint and power/ground pin assignments match, critical signal mappings differ - for example, ADSP-SC571BSWZ-4 repurposes several GPIO pins as additional Link Port signals, and ADSP-21571BSWZ-4 disables the Arm Cortex-A5 entirely, reallocating those pins to SHARC+ peripherals. Pin compatibility must be verified per variant using the respective "GPIO Multiplexing for 176-Lead LQFP Package" section in each device's datasheet.
