Overview

ADSP-21593BBPZ8 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 SHARC+ 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 - deployed in automotive audio amplifiers and ANC/RNC systems.

For engineers reviewing the ADSP-21593BBPZ8 datasheet, ADSP-21593BBPZ8 pinout, ADSP-21593BBPZ8 application, or ADSP-21593BBPZ8 equivalent, key selection criteria include its LPC BGA package (400-ball, 0.8 mm pitch), absence of Arm core, dual SHARC+ architecture, 800/1000 MHz speed grade options, and automotive AEC-Q100 qualification.

Technical Context

The ADSP-21593BBPZ8 implements two independent SHARC+ SIMD cores without an Arm Cortex-A5 processor - distinguishing it from ADSP-SC59x variants. Each core supports 32-/40-/64-bit floating-point and 32-bit fixed-point arithmetic, with dedicated DM/PM buses enabling simultaneous dual-data transfers per cycle.

It integrates a full peripheral set including 2× DAI (each with 4 full SPORTs, 2× S/PDIF, 8× ASRC, 8× PCG), 2× CAN FD, 4× UARTs, 6× I²C, 2× SPI + 2× Quad SPI + 1× Octal SPI, 2× Link Ports, and 40 GPIO + DAI pins - all mapped to the 400-ball BGA_ED low-peripheral-count (LPC) package.

FAQ

Does ADSP-21593BBPZ8 include an Arm Cortex-A5 core?

No, ADSP-21593BBPZ8 contains dual SHARC+ floating-point DSP cores only - it does not integrate an Arm Cortex-A5 processor. This distinguishes it from ADSP-SC592/SC594 variants. The ADSP-21593BBPZ8 is optimized for pure DSP workloads with deterministic real-time behavior, making it ideal for audio and control applications where Arm overhead is unnecessary. All documentation and pinout diagrams for ADSP-21593BBPZ8 confirm absence of Arm core signals and associated peripherals like GIC or L2 cache controller.

What is the maximum operating frequency of ADSP-21593BBPZ8?

The ADSP-21593BBPZ8 is offered in two speed grades: 800 MHz and 1000 MHz per SHARC+ core. The specific frequency is determined by the suffix in the full orderable part number - ADSP-21593BBPZ8 denotes the 800 MHz version. Both cores operate synchronously at the same frequency, and the device's electrical specifications (including timing margins and power consumption) are validated separately for each grade per Analog Devices' Rev. E datasheet Section "Specifications".

Is ADSP-21593BBPZ8 AEC-Q100 qualified?

Yes, ADSP-21593BBPZ8 is AEC-Q100 qualified for automotive applications across Grade 1 (−40°C to +125°C) temperature range. This qualification covers stress testing for reliability, ESD immunity, thermal cycling, and solderability - confirming suitability for under-dash and infotainment environments. The qualification status is explicitly stated in the "Automotive Products" section (p. 146) of the ADSP-21593/21594/SC592/SC594 Rev. E datasheet.

What package type does ADSP-21593BBPZ8 use, and is it pin-compatible with other SHARC+ processors?

ADSP-21593BBPZ8 uses a 400-ball BGA_ED package in Low Peripheral Count (LPC) configuration, measuring 17 mm × 17 mm with 0.8 mm ball pitch. It is pin-compatible with ADSP-21566, ADSP-21567, and ADSP-21569 processors - enabling direct replacement in existing LPC-layout designs. This compatibility is confirmed in Table 1 footnote 7 and the "Configuration of the ADSP-21593 400-Ball LPC BGA" section (p. 144) of the Rev. E datasheet.

Does ADSP-21593BBPZ8 support CAN FD communication?

No, ADSP-21593BBPZ8 does not support CAN FD. According to Table 1 in the Rev. E datasheet, CAN FD is marked "N/A" for ADSP-21593, while it is supported on ADSP-SC592/SC594 models. The ADSP-21593BBPZ8 retains the legacy CAN 2.0B interface only - consistent with its LPC peripheral set and target applications in audio-focused rather than vehicle-networking domains.
