Product details
Overview
ADSP-SC573KBCZ-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 supports 32-/40-/64-bit floating-point arithmetic. Used in automotive infotainment and professional audio systems requiring real-time signal processing and application-level OS support.
For engineers reviewing the ADSP-SC573KBCZ-4 datasheet, ADSP-SC573KBCZ-4 pinout, ADSP-SC573KBCZ-4 application, or ADSP-SC573KBCZ-4 equivalent, key selection criteria include dual-core SHARC+ clock speed, Arm Cortex-A5 integration, 400-ball CSP_BGA package compatibility, AEC-Q100 qualification, and DDR3/DDR2/LPDDR1 memory controller support.
Technical Context
The ADSP-SC573KBCZ-4 implements a heterogeneous dual-domain architecture: two SHARC+ cores operate independently at up to 500 MHz with dedicated 384 kB L1 SRAM each, while the Arm Cortex-A5 core runs at 500 MHz with 32 kB I-cache, 32 kB D-cache, and 256 kB L2 cache. All cores share a coherent system fabric backed by 1 MB L2 SRAM with ECC and a 16-bit DDR3/DDR2/LPDDR1 interface.
Peripherals include dual CAN 2.0 controllers, three UARTs, two SPI + one quad-SPI, three I²C interfaces, USB 2.0 HS with PHY, EMAC supporting 10/100/1000 Mbps with IEEE 1588, SDIO/eMMC, eight general-purpose timers, and an 8-channel 12-bit HADC - all mapped via a configurable Signal Routing Unit (SRU) and supported by hardware accelerators for FIR/IIR filtering and cryptographic operations.

FAQ
What is the maximum operating temperature range for the ADSP-SC573KBCZ-4?
The ADSP-SC573KBCZ-4 is qualified to AEC-Q100 Grade 2 specifications, supporting continuous operation from −40°C to +105°C ambient temperature. This rating applies to the full 400-ball CSP_BGA package and is verified across voltage, frequency, and process corners - enabling deployment in engine bay proximity or sealed cockpit enclosures without derating.
Does the ADSP-SC573KBCZ-4 support secure boot with cryptographic verification?
Yes, the ADSP-SC573KBCZ-4 includes hardware-accelerated secure boot with AES-128/256, SHA-256, and RSA-2048 support. Boot firmware is authenticated before execution using keys stored in OTP memory, and the entire chain - from ROM bootloader to SHARC+ and Arm application images - is cryptographically verified. This capability is enabled by the integrated cryptographic engine and Arm TrustZone isolation.
Can the SHARC+ cores and Arm Cortex-A5 core access the same L2 SRAM concurrently?
Yes, the ADSP-SC573KBCZ-4 implements a coherent system fabric with hardware-managed cache coherency between the SHARC+ cores and Arm Cortex-A5 core. The 1 MB L2 SRAM with ECC is accessible by all three cores with atomic read-modify-write support, and the PL310 L2 cache controller ensures data consistency without software intervention during shared-memory operations.
What peripheral interfaces does the ADSP-SC573KBCZ-4 provide for audio I/O?
The ADSP-SC573KBCZ-4 integrates four full SPORT interfaces, one S/PDIF transceiver, four asynchronous sample-rate converters (ASRC), two precision clock generators (PCG), and a digital audio interface (DAI) with 20 pin buffers. These enable direct connection to ADCs, DACs, codecs, and digital audio networks - supporting up to 64-channel I²S/TDM streams and seamless sample rate translation between asynchronous domains.
Is the ADSP-SC573KBCZ-4 pin-compatible with other members of the ADSP-SC57x family?
Yes, the ADSP-SC573KBCZ-4 shares identical 400-ball CSP_BGA mechanical and electrical pinout with ADSP-SC572KBCZ-4 and ADSP-SC589KBCZ-4. This allows drop-in replacement in existing designs when upgrading to higher clock speeds or additional peripherals - provided power delivery, thermal management, and signal integrity constraints are met for the target variant.
