Analog Devices Inc. ADSP-SC584KBCZ-3A

Overview

ADSP-SC584KBCZ-3A 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 integrates 5 Mb L1 SRAM per SHARC+ core (with parity), 256 kB L2 SRAM with ECC, and supports 32-/40-/64-bit floating-point arithmetic. Used in automotive infotainment head units requiring real-time audio processing and Linux-based application management.

For engineers reviewing the ADSP-SC584KBCZ-3A datasheet, ADSP-SC584KBCZ-3A pinout, ADSP-SC584KBCZ-3A application, or ADSP-SC584KBCZ-3A equivalent, key selection considerations include dual-core SHARC+ clock speed, Arm Cortex-A5 cache configuration, L2 memory ECC support, CAN2.0 interface count, and 349-ball 0.8 mm pitch BGA package compatibility.

Technical Context

The ADSP-SC584KBCZ-3A implements a heterogeneous dual-domain architecture: one Arm Cortex-A5 core handles high-level OS tasks (Linux/Android) and peripheral control, while two SHARC+ cores execute deterministic, low-latency signal processing (FFT, FIR, ASRC, S/PDIF). The cores share a coherent system fabric with L2 cache controller (PL310) and crossbar interconnect.

It features dedicated hardware acceleration for audio functions-including four ASRC pairs, two precision clock generators, full SPORT interfaces, and an 8-channel 12-bit HADC-alongside safety mechanisms including dual CRC, watchdog timers, thermal monitor unit (TMU), and AEC-Q100 qualification for automotive use.

Key Specifications

Pinout & Package

ADSP-SC584KBCZ-3A uses a 349-ball CSP_BGA package (19 mm × 19 mm, 0.8 mm pitch), RoHS compliant and qualified for automotive temperature range (−40°C to +105°C). Ball assignments follow Analog Devices' standardized 349-BGA layout with dedicated power, ground, I/O banks, and differential signaling groups for high-speed interfaces (USB, EMAC, DDR).

FAQ

What is the maximum operating frequency of each SHARC+ core in the ADSP-SC584KBCZ-3A?

The ADSP-SC584KBCZ-3A supports up to 500 MHz per SHARC+ core, as confirmed in Table 2 of the Rev. C datasheet. This clock speed enables ≥2000 MFLOPS per core for floating-point-intensive audio algorithms such as FIR filtering, FFT-based spectral analysis, and ASRC resampling. The Arm Cortex-A5 core also operates at 500 MHz, delivering 800 DMIPS with NEON/VFPv4 support.

Does the ADSP-SC584KBCZ-3A include built-in memory protection for functional safety compliance?

Yes, the ADSP-SC584KBCZ-3A includes multiple hardware-enforced safety mechanisms: System Memory Protection Unit (SMPU), System Protection Unit (SPU), dual CRC engines, watchdog timers, and Thermal Monitor Unit (TMU). These features collectively support ISO 26262 ASIL-B development and are documented in the Safety Features section (page 15) of the Rev. C datasheet.

How many CAN 2.0 interfaces does the ADSP-SC584KBCZ-3A support, and are they isolated from other peripherals?

The ADSP-SC584KBCZ-3A integrates two independent CAN2.0 controllers (CAN0 and CAN1), each with dedicated TX/RX pins and message RAM. They operate autonomously from the Arm and SHARC+ cores via DMA and are electrically isolated from other peripherals by separate power domains and clock gating-enabling concurrent CAN messaging and audio processing without resource contention.

What audio-specific hardware accelerators are integrated into the ADSP-SC584KBCZ-3A?

The ADSP-SC584KBCZ-3A includes a comprehensive audio acceleration suite: four asynchronous sample-rate converters (ASRC), two precision clock generators (PCG), four full SPORT interfaces, eight-channel 12-bit HADC with programmable gain, S/PDIF Rx/Tx, and dedicated hardware engines for FFT/IFFT, FIR, IIR, harmonic analysis, and SINC filtering-all accessible directly from SHARC+ cores without CPU intervention.

Is the ADSP-SC584KBCZ-3A pin-compatible with other members of the ADSP-SC58x family?

No, the ADSP-SC584KBCZ-3A is not pin-compatible with ADSP-SC582 or ADSP-SC583 due to differing peripheral sets and pin allocations, though it shares the same 349-ball CSP_BGA package footprint as ADSP-SC582/SC583. Pinouts differ significantly-for example, ADSP-SC584 includes USB 2.0 HS PHY signals absent in SC582-requiring unique PCB layout per variant.
