It operates at 500 MHz per SHARC+ core, integrates 5 Mb L1 SRAM per core with parity, supports 32-/40-/64-bit floating-point arithmetic, and features dual CAN 2.0 interfaces and PCIe 2.0 (1 lane) - deployed in professional audio mixers and ADAS domain controllers.

For engineers reviewing the ADSP-21583KBCZ-4A datasheet, ADSP-21583KBCZ-4A pinout, ADSP-21583KBCZ-4A application, or ADSP-21583KBCZ-4A equivalent, key selection considerations include SHARC+ core frequency, L1 SRAM configuration, Arm Cortex-A5 integration level, PCIe/USB/EMAC peripheral availability, and AEC-Q100 qualification status.

Technical Context

The ADSP-21583KBCZ-4A implements a heterogeneous dual-architecture system: one SHARC+ core running at 500 MHz (second SHARC+ core disabled), paired with a 500 MHz Arm Cortex-A5 core featuring 32 kB I-cache/32 kB D-cache and 256 kB L2 cache with parity. Its memory subsystem includes 5 Mb L1 SRAM per SHARC+ core (configurable as SRAM or cache), 256 kB shared L2 SRAM with ECC, and 512 kB L2 ROM.

System-level acceleration includes hardware FFT/IFFT, FIR/IIR, harmonic analysis (HAE), SINC filtering, cryptographic engines, and Arm TrustZone security. Peripheral integration covers 2× CAN 2.0, 2× USB 2.0 HS, 2× EMAC, PCIe 2.0 (1 lane), SD/SDIO/eMMC, and 8-channel 12-bit HADC - all mapped via a configurable signal routing unit (SRU) and system crossbar.

FAQ

What is the maximum operating frequency of each core in the ADSP-21583KBCZ-4A?

The ADSP-21583KBCZ-4A features one active SHARC+ core rated at 500 MHz and an Arm Cortex-A5 core also operating at 500 MHz. The second SHARC+ core is disabled in this variant. Both cores sustain their rated frequencies under automotive temperature conditions (−40°C to +105°C) with appropriate power delivery and thermal management per the datasheet's operating conditions table.

Does the ADSP-21583KBCZ-4A support PCIe Gen2, and what are the electrical requirements?

Yes, the ADSP-21583KBCZ-4A integrates a PCIe 2.0 controller supporting 1 lane at 5 GT/s. It requires a 100 MHz differential reference clock (PCIE_REFCLK_P/N), AC-coupled lanes with 85 Ω differential impedance, and proper termination per PCI-SIG specifications. The interface supports root complex and endpoint modes, and is validated per Analog Devices' ADSP-21583 hardware design guide.

How is memory configured between the SHARC+ and Arm Cortex-A5 cores in the ADSP-21583KBCZ-4A?

In the ADSP-21583KBCZ-4A, each SHARC+ core has private 5 Mb L1 SRAM (640 kB), configurable as cache or SRAM. The Arm Cortex-A5 accesses shared resources including 256 kB L2 SRAM with ECC, 512 kB L2 ROM, and external DDR via the L3 interface. Coherency is maintained through the system fabric and L2 cache controller, with explicit memory barriers required for cross-core data sharing.

Is the ADSP-21583KBCZ-4A AEC-Q100 qualified, and which grade does it meet?

Yes, the ADSP-21583KBCZ-4A is AEC-Q100 qualified to Grade 2, specifying operation from −40°C to +105°C ambient temperature. This qualification covers stress testing for HTOL, TCT, ESD, and other automotive reliability requirements, making it suitable for under-hood and cockpit applications where thermal robustness and long-term stability are critical.

What development tools and software support are available for the ADSP-21583KBCZ-4A?

Analog Devices provides CrossCore Embedded Studio (CCES) with SHARC+ and Arm Cortex-A5 debug support, VisualDSP++ legacy compatibility mode, SHARC+ C/C++ compiler, and Linux BSP for the Arm core. Hardware tools include the ADZS-SC589-EZLITE evaluation board and ICE-1000/2000 emulators. All tools fully support the ADSP-21583KBCZ-4A out-of-the-box.
