ADSP-21567BBCZ6

Digital Signal Processor Dsp Overview

The ADSP-21567BBCZ6 is a high-performance digital signal processor from the SHARC+ family, manufactured by Analog Devices Inc. It features a single-core architecture with a maximum clock frequency of 600 MHz. The device supports 32-bit, 40-bit, and 64-bit floating-point operations alongside 32-bit fixed-point processing. It integrates 5 Mb (640 kB) of Level 1 SRAM with parity protection and up to 8 Mb (1 MB) of Level 2 SRAM with ECC. The processor operates at a core voltage of 1 V and includes an L3 interface for DDR3/DDR3L SDRAM connectivity. It is housed in a 17 mm × 17 mm, 400-ball CSP_BGA package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade and package configuration against the official Analog Devices ordering guide. Confirm that the 400-ball CSP_BGA footprint matches the PCB design requirements. Ensure compliance with RoHS standards and check for any automotive qualification certifications if required for the target application environment.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high floating-point performance with integrated audio interfaces. Compare L2 memory capacity needs; this part offers up to 1 MB L2 SRAM. Consider the 600 MHz speed grade relative to computational load. Verify compatibility with existing SHARC development tools and ensure the system power budget accommodates the 1 V core supply.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2156x series, which includes variants like the ADSP-21569 and ADSP-21566. The ADSP-21567 specifically targets mid-to-high performance segments within the SHARC+ family, offering a balance between computational throughput and memory resources compared to higher-speed or lower-memory counterparts in the same product line.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the ADSP-2156x family include the ADSP-21566 (400 MHz) or ADSP-21569 (800/1000 MHz), provided pinout and memory configurations are compatible. Verify instruction set compatibility and peripheral availability when cross-referencing with other SHARC+ processors.
