Product details
Overview
ADSP-21593KBPZ8 from Analog Devices is a SHARC+ dual-core floating-point DSP with no Arm Cortex-A5 core, operating at up to 800 MHz or 1000 MHz per core, featuring 2 × 640 kB L1 SRAM with parity, 2 MB shared L2 SRAM with ECC, and integrated FIR/IIR accelerators running up to 1 GHz - designed for high-fidelity automotive audio amplifiers and active noise cancellation systems.
For engineers reviewing the ADSP-21593KBPZ8 datasheet, ADSP-21593KBPZ8 pinout, ADSP-21593KBPZ8 application, or ADSP-21593KBPZ8 equivalent, key selection criteria include its LPC BGA package compatibility with ADSP-21566/21567/21569, absence of Arm core and EMAC/USB/ePPI peripherals, and deterministic real-time signal processing capability in temperature-grade industrial and automotive environments.
Technical Context
This is a SHARC+ SIMD architecture processor supporting 32-/40-/64-bit floating-point and 32-bit fixed-point arithmetic, with dual independent computational elements (PEx/PEy), zero-overhead circular buffers via two DAGs, and VISA instruction encoding for code density. It implements a modified Harvard memory architecture with separate PM/DM buses enabling simultaneous 2×64-bit data + 64-bit instruction fetch per cycle.
The device integrates a system crossbar and 8 MemDMAs, supports ASRC (8 pairs), S/PDIF Rx/Tx (2×), full SPORTs (8), PDM microphone input (2×4-channel), and 6× I²C - all mapped to a 400-ball BGA_ED (0.8 mm pitch) low-peripheral-count package with 40 GPIO + 28 DAI pins and AEC-Q100 qualification.

FAQ
What is the maximum operating frequency of the ADSP-21593KBPZ8?
The ADSP-21593KBPZ8 operates at up to 800 MHz or 1000 MHz per SHARC+ core, depending on speed grade and thermal conditions. This frequency governs real-time execution of audio algorithms such as FIR filtering and FFT-based spectral analysis. The actual sustained clock rate must be validated against junction temperature and voltage stability per the device's Electrical Characteristics table in the Rev. E datasheet.
Does the ADSP-21593KBPZ8 include an Arm Cortex-A5 core?
No, the ADSP-21593KBPZ8 does not include an Arm Cortex-A5 core. It is a dual SHARC+ floating-point DSP-only variant. The Arm Cortex-A5 is present only in ADSP-SC592/SC594 and ADSP-21594 models. This makes ADSP-21593KBPZ8 ideal for pure real-time signal processing tasks where deterministic latency and floating-point throughput are prioritized over general-purpose OS support.
Is the ADSP-21593KBPZ8 pin-compatible with other ADSP-2156x processors?
Yes, the ADSP-21593KBPZ8 uses the 400-ball Low Peripheral Count (LPC) BGA_ED package and is explicitly pin-compatible with ADSP-21566, ADSP-21567, and ADSP-21569 processors. This enables direct PCB replacement and firmware reuse for incremental performance upgrades in existing audio amplifier or ANC platforms without layout changes.
What memory protection features does the ADSP-21593KBPZ8 support?
The ADSP-21593KBPZ8 supports L1 SRAM parity checking, L2 SRAM ECC protection, and a System Memory Protection Unit (SMPU) that enforces access permissions across memory regions. These features prevent unintended memory corruption during interrupt-driven audio processing and are essential for ISO 26262-compliant automotive audio systems.
Which audio interfaces are supported by the ADSP-21593KBPZ8?
The ADSP-21593KBPZ8 supports 2× S/PDIF Rx/Tx, 8× full SPORTs, 8× ASRC pairs, 2× 4-channel PDM microphone inputs, and 2× Link Ports. It does not support USB, EMAC, or ePPI - those interfaces are exclusive to the HPC variants (e.g., ADSP-21594). This interface set is optimized for multi-microphone beamforming and multi-speaker spatial audio rendering.
