Product details
Overview
ADSP-SC570CSWZ-42 from Analog Devices is a dual-core SHARC+ DSP with integrated Arm Cortex-A5 processor, delivering 450 MHz per SHARC+ core 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 for high-fidelity audio and real-time signal processing in automotive infotainment systems.
For engineers reviewing the ADSP-SC570CSWZ-42 datasheet, ADSP-SC570CSWZ-42 pinout, ADSP-SC570CSWZ-42 application, or ADSP-SC570CSWZ-42 equivalent, key selection criteria include dual-core SHARC+ clock speed, L1 SRAM configuration, Arm Cortex-A5 cache hierarchy, AEC-Q100 qualification, and 400-ball CSP_BGA package compatibility with automotive thermal and safety requirements.
Technical Context
The ADSP-SC570CSWZ-42 implements a heterogeneous dual-domain architecture: one SHARC+ core (450 MHz) paired with an Arm Cortex-A5 core (450 MHz), sharing a unified system fabric and L2 SRAM (1 MB). Its memory subsystem includes parity-protected 32 kB L1 instruction and data caches for Arm, and configurable 384 kB L1 SRAM per SHARC+ core supporting single-cycle DM/PM accesses.
Peripherals include two CAN 2.0 controllers, three UARTs, three I²C interfaces, quad-SPI, two link ports, 8-channel 12-bit HADC, S/PDIF Rx/Tx, ASRCs, and EMAC supporting 10/100 Mbps Ethernet - all managed via a centralized Signal Routing Unit (SRU) and System Event Controller (SEC) with GIC-based interrupt arbitration.
