Product details
Overview
ADSP-SC570KSWZ-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 interfaces, 3 UARTs, and 8-channel 12-bit HADC.
For engineers reviewing the ADSP-SC570KSWZ-4 datasheet, ADSP-SC570KSWZ-4 pinout, ADSP-SC570KSWZ-4 application, or ADSP-SC570KSWZ-4 equivalent, key selection criteria include SHARC+ core clock speed, L1 SRAM configuration, automotive AEC-Q100 qualification, 176-lead LQFP_EP package compatibility, and dual-core deterministic real-time signal processing capability.
Technical Context
The ADSP-SC570KSWZ-4 implements a heterogeneous dual-core architecture: one SHARC+ core running at up to 450 MHz and one Arm Cortex-A5 core also at 450 MHz, sharing a unified system fabric with L2 SRAM (1 MB) and memory protection units. Its SHARC+ core supports SIMD execution with PEx/PEy computational elements and VISA instruction encoding for code density.
System-level features include Arm TrustZone security extensions, cryptographic hardware accelerators, FIR/IIR offload engines, and safety mechanisms such as dual CRC, watchdog timers, and thermal monitoring. Peripherals include 2× CAN2.0, 3× UART, 3× I²C, 2× SPI + 1× Quad-SPI, USB 2.0 HS, EMAC (10/100), and 8-channel 12-bit HADC - all mapped to the 176-lead LQFP_EP package.

FAQ
What is the maximum operating frequency of the SHARC+ core in the ADSP-SC570KSWZ-4?
The SHARC+ core in the ADSP-SC570KSWZ-4 operates at a maximum frequency of 450 MHz. This speed is specified under recommended operating conditions (VDD_CORE = 1.05 V, junction temperature ≤ +105°C) and enables deterministic execution of audio and control algorithms with cycle-accurate timing. The ADSP-SC570KSWZ-4 maintains this rating across its full automotive temperature range.
Does the ADSP-SC570KSWZ-4 support AEC-Q100 qualification, and what grade does it meet?
Yes, the ADSP-SC570KSWZ-4 is AEC-Q100 qualified to Grade 2, covering an operating temperature range of −40°C to +105°C. This qualification applies to the full device including SHARC+, Arm Cortex-A5, memory subsystems, and peripherals. The qualification documentation is available in Analog Devices' Automotive Products section (Rev. C, p. 140).
How much on-chip L1 SRAM does the ADSP-SC570KSWZ-4 provide, and how is it allocated?
The ADSP-SC570KSWZ-4 provides 384 kB of L1 SRAM dedicated to its single SHARC+ core, with optional parity protection. This memory is fully configurable as program memory (PM), data memory (DM), or instruction cache - typical configurations allocate 128 kB for PM, 512 kB for DM, and 128 kB for cache. The Arm Cortex-A5 accesses this memory space via multicycle reads/writes.
Which package type and pin count does the ADSP-SC570KSWZ-4 use?
The ADSP-SC570KSWZ-4 uses a 176-lead LQFP_EP package with an exposed thermal pad (17 mm × 17 mm footprint). This package supports GPIO multiplexing across Ports A–D (64 pins) and includes 20 dedicated DAI pins. Ball/lead assignments and signal descriptions are documented in Rev. C, pages 38–43.
