For engineers reviewing the ADSP-21584CBCZ-4A datasheet, ADSP-21584CBCZ-4A pinout, ADSP-21584CBCZ-4A application, or ADSP-21584CBCZ-4A equivalent, key selection criteria include dual-core SHARC+ clock speed, L1 SRAM configuration options, Arm Cortex-A5 cache hierarchy, automotive AEC-Q100 qualification, and 349-ball 0.8 mm pitch BGA package compatibility.

Technical Context

The ADSP-21584CBCZ-4A implements a heterogeneous dual-processor architecture: one SHARC+ core running at 500 MHz and one Arm Cortex-A5 core also at 500 MHz, both sharing 256 kB L2 SRAM with ECC and 512 kB L2 ROM. Its memory subsystem includes independently configurable L1 SRAM blocks (up to 640 kB per SHARC+ core) supporting single-cycle access and optional cache mode.

System-level integration includes two Link Ports, three UARTs, two I²C interfaces, dual CAN 2.0 controllers, two USB 2.0 HS PHYs, and a full SPORT interface set - all routed through a programmable Signal Routing Unit (SRU). The device supports TrustZone security, fast secure boot, and cryptographic acceleration for IP protection in automotive and professional audio systems.

FAQ

What is the maximum operating frequency of each SHARC+ core in the ADSP-21584CBCZ-4A?

The ADSP-21584CBCZ-4A features two SHARC+ cores, each rated for operation up to 500 MHz. This frequency is guaranteed across the full automotive temperature range (−40°C to +105°C) and supports deterministic execution of real-time audio and control algorithms. The ADSP-21584CBCZ-4A datasheet specifies this as the maximum sustained core clock under validated thermal and voltage conditions.

Does the ADSP-21584CBCZ-4A include an Arm Cortex-A5 processor, and what are its key capabilities?

Yes, the ADSP-21584CBCZ-4A integrates a 500 MHz Arm Cortex-A5 core with 32 kB L1 instruction cache, 32 kB L1 data cache, and 256 kB L2 cache with parity. It supports NEON, VFPv4-D16, Jazelle, and TrustZone security extensions. The Arm core runs Linux or bare-metal applications while coordinating with SHARC+ cores via shared L2 memory and hardware semaphores - a capability confirmed in the ADSP-21584CBCZ-4A reference manual.

What package type and ball count does the ADSP-21584CBCZ-4A use?

The ADSP-21584CBCZ-4A uses a 349-ball CSP_BGA package measuring 19 mm × 19 mm with 0.8 mm pitch. It is RoHS compliant and qualified for automotive Grade 2 operation (−40°C to +105°C). Ball assignments match Analog Devices' standard 349-BGA footprint, including dedicated power/ground rings and high-speed I/O groups - verified in the ADSP-21584CBCZ-4A mechanical drawings and PCB layout guide.

Is the ADSP-21584CBCZ-4A AEC-Q100 qualified, and for which grade?

Yes, the ADSP-21584CBCZ-4A is AEC-Q100 qualified for Grade 2 (−40°C to +105°C), making it suitable for under-hood and cabin automotive applications. This qualification covers stress testing for temperature cycling, humidity bias, ESD, and latch-up - documented in Analog Devices' official AEC-Q100 certificate and automotive product summary for the ADSP-21584CBCZ-4A.

Which hardware accelerators are integrated into the ADSP-21584CBCZ-4A?

The ADSP-21584CBCZ-4A includes dedicated hardware accelerators for FFT/IFFT, FIR/IIR filtering, harmonic analysis (HAE), SINC decimation, and cryptographic operations (AES, SHA, RSA). These engines operate independently of the SHARC+ and Arm cores, offloading computationally intensive tasks and reducing overall power consumption - confirmed in the ADSP-21584CBCZ-4A system features table and accelerator subsystem description.
