Analog Devices Inc. ADSP-SC582CBCZ-4A

Overview

ADSP-SC582CBCZ-4A from Analog Devices is a dual-core SHARC+ and Arm Cortex-A5 heterogeneous processor for high-performance audio, automotive, and industrial signal processing. It integrates two SHARC+ floating-point DSP cores (450 MHz each), one Arm Cortex-A5 core (450 MHz), 5 Mb L1 SRAM per SHARC+ core with parity, 256 kB L2 SRAM with ECC, and dual 2× CAN 2.0 interfaces. It targets real-time audio processing in automotive infotainment head units.

For engineers reviewing the ADSP-SC582CBCZ-4A datasheet, ADSP-SC582CBCZ-4A pinout, ADSP-SC582CBCZ-4A application, or ADSP-SC582CBCZ-4A equivalent, key selection criteria include SHARC+ core clock speed, L1 SRAM configuration options, Arm Cortex-A5 cache hierarchy, CAN interface count, and 349-ball 0.8 mm pitch BGA package compatibility with automotive thermal requirements.

Technical Context

The ADSP-SC582CBCZ-4A implements a tightly coupled heterogeneous architecture: dual SHARC+ cores execute deterministic, low-latency floating-point signal processing (32/40/64-bit) while the Arm Cortex-A5 handles OS services, connectivity stack management, and system control. The cores share a coherent L2 memory subsystem via a system fabric with PL310 L2 cache controller.

Its memory subsystem includes per-core 5 Mb L1 SRAM (configurable as SRAM or cache), 256 kB shared L2 SRAM with ECC, and 512 kB L2 ROM. Peripheral integration includes 2× CAN2.0 controllers, 3× UARTs, 2× USB 2.0 HS ports, 2× EMAC, and 8-channel 12-bit HADC - all mapped to dedicated I/O domains with configurable GPIO multiplexing.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating temperature range for ADSP-SC582CBCZ-4A?

ADSP-SC582CBCZ-4A is qualified to AEC-Q100 Grade 2, supporting continuous operation from −40°C to +105°C ambient temperature. This rating covers junction temperatures up to 125°C under specified power dissipation and PCB thermal design conditions, making it suitable for under-dash automotive environments.

Does ADSP-SC582CBCZ-4A support secure boot with cryptographic verification?

Yes, ADSP-SC582CBCZ-4A includes hardware cryptographic accelerators and fast secure boot logic that validates signed firmware images stored in on-chip ROM or external flash before execution. This ensures IP protection and prevents unauthorized code execution during ADSP-SC582CBCZ-4A startup.

How many CAN 2.0 interfaces does ADSP-SC582CBCZ-4A integrate?

ADSP-SC582CBCZ-4A integrates two independent CAN2.0 controllers, each with dedicated TX/RX pins and full protocol handling including message filtering, error detection, and automatic retransmission. Both controllers operate concurrently and support bit rates up to 1 Mbps.

Can ADSP-SC582CBCZ-4A run a real-time operating system on its Arm Cortex-A5 core?

Yes, ADSP-SC582CBCZ-4A's 450 MHz Arm Cortex-A5 core with 32 kB L1 instruction cache, 32 kB L1 data cache, and 256 kB L2 cache supports real-time OSes such as FreeRTOS, Zephyr, or Linux PREEMPT_RT. Its memory protection unit and interrupt controller enable deterministic scheduling for time-critical tasks alongside SHARC+ processing.

Is the L1 SRAM in ADSP-SC582CBCZ-4A configurable as cache or scratchpad memory?

Yes, the 5 Mb L1 SRAM per SHARC+ core in ADSP-SC582CBCZ-4A is fully configurable - individual memory blocks can be assigned as instruction cache, data cache, or directly addressable SRAM. Configuration is controlled via core memory-mapped registers and persists across resets.
