Product details
Overview
ADSP-21567BBCZ6 from Analog Devices is a SHARC+ single-core high-performance floating-point DSP operating at up to 800 MHz, featuring 5 MB L1 SRAM with parity, 1024 kB L2 SRAM with ECC, and integrated FIR/IIR accelerators. It supports 32-/40-/64-bit floating-point and 32-bit fixed-point arithmetic, and targets automotive audio amplifier and ANC/RNC systems requiring deterministic real-time signal processing.
For engineers reviewing the ADSP-21567BBCZ6 datasheet, ADSP-21567BBCZ6 pinout, ADSP-21567BBCZ6 application, or ADSP-21567BBCZ6 equivalent, key selection criteria include its 400-ball CSP_BGA package (0.8 mm pitch), AEC-Q100 qualification, DDR3L interface, dual ASRCs, and hardware crypto acceleration for secure boot.
Technical Context
The ADSP-21567BBCZ6 implements a SIMD SHARC+ core with two parallel processing elements (PEx/PEy), each supporting IEEE 32-/64-bit FP and 40-bit extended-precision operations in single-cycle execution for most instructions. Its memory architecture includes four configurable L1 SRAM blocks (total 5 MB) accessible via dedicated PM/DM buses, enabling simultaneous instruction fetch and dual data transfers per cycle.
System-level integration includes a dedicated SHARC fabric connecting FIR/IIR accelerators directly to L1 memory at CCLK speed, bypassing system fabric latency; a 16-bit DDR3/DDR3L L3 interface; and safety features including memory protection units (SMPU, SPU), dual CRC engines, and thermal monitoring unit (TMU) compliant with automotive requirements.

FAQ
What is the maximum operating frequency of the ADSP-21567BBCZ6?
The ADSP-21567BBCZ6 is rated for a maximum core frequency of 800 MHz under automotive temperature conditions (−40°C to +105°C). This speed grade is confirmed in the official Analog Devices ordering guide and supported by its 0.95 V VDD_CORE supply specification. The ADSP-21567BBCZ6 achieves this performance while maintaining full L1 SRAM parity checking and real-time interrupt response guarantees required for ANC and amplifier applications.
Does the ADSP-21567BBCZ6 support DDR3L memory interfacing?
Yes, the ADSP-21567BBCZ6 integrates a dedicated 16-bit DDR3/DDR3L controller as part of its L3 memory interface. It supports DDR3L-800 (400 MHz clock) operation with programmable timing parameters, on-die termination, and automatic calibration sequences. This interface is electrically and logically distinct from legacy SDRAM controllers and is documented in the "L3 Memory Interface" section of the ADSP-21567BBCZ6 datasheet Rev. D.
Is the ADSP-21567BBCZ6 qualified for automotive use?
Yes, the ADSP-21567BBCZ6 is AEC-Q100 qualified for Grade 2 (−40°C to +105°C ambient), with full qualification testing including HTOL, TC, and ESD per JESD22 standards. Its safety features - including SMPU, SPU, dual CRC engines, and TMU - are designed to meet ISO 26262 ASIL-B requirements when implemented per Analog Devices' functional safety manual. This makes the ADSP-21567BBCZ6 suitable for audio amplifier and ANC modules in production vehicles.
How much on-chip memory does the ADSP-21567BBCZ6 include?
The ADSP-21567BBCZ6 includes 5 MB (640 kB) of on-chip L1 SRAM with parity protection, organized into four configurable blocks, and 1024 kB of L2 SRAM with ECC protection. L1 memory supports single-cycle access for both instructions and data, while L2 serves as error-corrected scratchpad and DMA descriptor storage. These memory resources are fixed for the ADSP-21567BBCZ6 variant and do not vary with speed grade.
What audio interfaces are integrated into the ADSP-21567BBCZ6?
The ADSP-21567BBCZ6 integrates two full SPORTs (serial port interfaces), two S/PDIF transceivers (Rx/Tx), two digital audio interfaces (DAI) with signal routing units (SRU), and two sets of four asynchronous sample rate converters (ASRC). These peripherals support I2S, TDM, left-justified, and custom audio protocols up to 32 channels per interface, enabling complex multi-source audio routing without external interface ICs.
