Product details
Overview
ADSC570WCSWZ4202 from Analog Devices is a dual-core SHARC+ DSP with integrated Arm Cortex-A5 processor, delivering 450 MHz SHARC+ core performance and 500 MHz Arm operation for real-time audio and automotive signal processing. It features 384 kB L1 SRAM per SHARC+ core, 256 kB L2 cache, and AEC-Q100 qualification for automotive infotainment systems.
For engineers reviewing the ADSC570WCSWZ4202 datasheet, ADSC570WCSWZ4202 pinout, ADSC570WCSWZ4202 application, or ADSC570WCSWZ4202 equivalent, key selection criteria include dual-core floating-point throughput, on-chip memory partitioning, CAN2.0 interface count, DDR3L controller presence, and 176-lead LQFP_EP package compatibility with automotive thermal requirements.
Technical Context
The ADSC570WCSWZ4202 implements a heterogeneous dual-processor architecture: one SHARC+ core (450 MHz) paired with an Arm Cortex-A5 (500 MHz), sharing a unified system fabric and 1 MB ECC-protected L2 SRAM. Its memory subsystem supports 32/40/64-bit floating-point arithmetic and includes parity-protected L1 caches (32 kB I-cache / 32 kB D-cache) and hardware-accelerated FIR/IIR offload engines.
Peripherals include two CAN2.0 controllers, three UARTs, three I²C interfaces, dual SPI plus quad-SPI, eight general-purpose timers, and an 8-channel 12-bit HADC - all mapped to 64 GPIO + 20 DAI pins in the 176-lead LQFP_EP package. The device integrates Arm TrustZone security, cryptographic accelerators, and fast secure boot with OTP memory.

FAQ
What is the maximum operating frequency of the SHARC+ core in ADSC570WCSWZ4202?
The SHARC+ core in ADSC570WCSWZ4202 operates at a maximum frequency of 450 MHz. This rating is validated across the full automotive temperature range (−40°C to +125°C) and is specified in the official Analog Devices ADSP-SC570 datasheet Rev. C. The Arm Cortex-A5 core runs concurrently at 500 MHz, enabling tightly coupled heterogeneous processing within the ADSC570WCSWZ4202 die.
Does ADSC570WCSWZ4202 support DDR3 memory interfaces?
No, ADSC570WCSWZ4202 does not include a DDR3 memory controller. According to the Analog Devices ordering guide and feature comparison tables, DDR3/DDR2/LPDDR1 support is only present in the ADSP-SC572W and ADSP-SC573W variants. ADSC570WCSWZ4202 relies solely on its 1 MB on-chip L2 SRAM with ECC and 384 kB per-core L1 SRAM for data and program storage.
What package type and pin count does ADSC570WCSWZ4202 use?
ADSC570WCSWZ4202 uses a 176-lead LQFP_EP (Low-Profile Quad Flat Package with Exposed Pad) package. This RoHS-compliant package measures 24 mm × 24 mm with 0.5 mm lead pitch and includes an exposed thermal pad for enhanced heat dissipation - essential for automotive applications operating at extended temperature ranges.
Is ADSC570WCSWZ4202 AEC-Q100 qualified?
Yes, ADSC570WCSWZ4202 is AEC-Q100 qualified for automotive applications. Specifically, it meets Grade 2 requirements (operating temperature range −40°C to +125°C) and includes integrated safety mechanisms such as dual CRC engines, fault management unit (FMU), and watchdog timers - all documented in the ADSP-SC57x automotive feature table (Rev. C, Table 3).
How many CAN2.0 interfaces does ADSC570WCSWZ4202 provide?
ADSC570WCSWZ4202 provides two independent CAN2.0 controllers (CAN0 and CAN1), each with dedicated RX/TX pins and full protocol stack support up to 1 Mbps. These interfaces are electrically isolated from the core logic and require external CAN transceivers; pin assignments are defined in the 176-lead LQFP signal descriptions section of the ADSP-SC570 datasheet.
