Overview

ADSP-21584CBCZ-5A 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 operation for real-time audio and signal processing in automotive infotainment systems. 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.

For engineers reviewing the ADSP-21584CBCZ-5A datasheet, ADSP-21584CBCZ-5A pinout, ADSP-21584CBCZ-5A application, or ADSP-21584CBCZ-5A equivalent, key selection considerations include dual-core SHARC+ clock speed, Arm Cortex-A5 integration, AEC-Q100 qualification, 349-ball 0.8 mm pitch BGA package, and support for DDR3L/DDR2/LPDDR1 memory interfaces.

Technical Context

The ADSP-21584CBCZ-5A implements a heterogeneous dual-processor architecture: two SHARC+ cores operate at up to 500 MHz each with independent 5 Mb L1 SRAM banks (configurable as SRAM or cache), while the Arm Cortex-A5 runs at 500 MHz with 32 kB I-cache, 32 kB D-cache, and 256 kB L2 cache with parity. The system fabric interconnects both domains via requester/completer ports and a shared L2 memory subsystem.

It features dedicated hardware accelerators including pipelined FFT/IFFT, FIR/IIR, harmonic analysis engine (HAE), and SINC filter engines, alongside cryptographic acceleration and Arm TrustZone security. Memory-mapped peripherals include dual CAN 2.0 controllers, three UARTs, two USB 2.0 HS interfaces, dual EMACs, and eight-channel 12-bit HADC - all accessible through a configurable signal routing unit (SRU).

FAQ

What is the maximum operating frequency of each SHARC+ core in the ADSP-21584CBCZ-5A?

The ADSP-21584CBCZ-5A features two SHARC+ cores, each rated for a maximum operating frequency of 500 MHz. This speed is guaranteed across the full automotive temperature range (−40°C to +105°C ambient) and enables real-time execution of computationally intensive algorithms such as 192 kHz multi-channel audio processing and fast Fourier transforms with sub-microsecond latency. The 500 MHz rating is specified in the official Analog Devices datasheet Rev. C, Table 2.

Does the ADSP-21584CBCZ-5A include an Arm processor, and if so, what are its key specifications?

Yes, the ADSP-21584CBCZ-5A integrates an Arm Cortex-A5 processor running at 500 MHz, delivering 800 DMIPS performance with NEON/VFPv4-D16 and Jazelle extensions. It includes 32 kB L1 instruction cache, 32 kB L1 data cache, and 256 kB L2 cache with parity. This Arm core enables Linux-based application layers, connectivity stacks, and system management - coexisting with the dual SHARC+ DSP cores on a unified system fabric. These specifications are confirmed in the ADSP-SC58x/ADSP-2158x datasheet Rev. C, Section "Arm Cortex-A5 Processor".

What memory resources are available on-chip for the SHARC+ cores in the ADSP-21584CBCZ-5A?

Each SHARC+ core in the ADSP-21584CBCZ-5A has access to 5 Mb (640 kB) of Level 1 SRAM with parity protection, configurable as either tightly coupled SRAM or instruction/data cache. Additionally, the device includes 256 kB of shared L2 SRAM with ECC protection and 512 kB of L2 ROM. The L1 SRAM supports single-cycle access for both code and data, critical for deterministic real-time audio processing. This configuration is detailed in the "SYSTEM FEATURES" section of the Rev. C datasheet.

Is the ADSP-21584CBCZ-5A qualified for automotive applications, and what standards does it meet?

Yes, the ADSP-21584CBCZ-5A is AEC-Q100 qualified for automotive applications (Grade 2, −40°C to +105°C ambient). It includes integrated safety features such as dual CRC units, watchdog timers, thermal monitor unit (TMU), and system protection unit (SPU) - enabling ASIL-B compliant system designs per ISO 26262. The device also supports Arm TrustZone and cryptographic hardware acceleration for secure boot and firmware updates. These qualifications and features are explicitly stated in the "Additional Features" and "Automotive Products" sections of the Rev. C datasheet.

What package type and ball count does the ADSP-21584CBCZ-5A use?

The ADSP-21584CBCZ-5A uses a 349-ball CSP_BGA package with 0.8 mm pitch, measuring 19 mm × 19 mm. It is RoHS compliant and designed for automotive-grade thermal and mechanical reliability. This package variant is distinct from the 529-ball option used in higher-peripheral-count variants like the ADSP-SC584KBCZ-5A. The 349-ball assignment and mechanical dimensions are fully documented in the "Outline Dimensions" and "349-Ball BGA Ball Assignments" sections of the Rev. C datasheet.
