ADSP-BF561SKBCZ-5A

Digital Signal Processor Dsp Overview

The ADSP-BF561SKBCZ-5A is a dual-core Blackfin symmetric multiprocessor digital signal processor manufactured by Analog Devices Inc. Operating at a clock rate of 533 MHz, it features two independent cores with 328 KB of on-chip memory, including L1 and L2 SRAM. The device utilizes a 256-ball CSPBGA package (17x17 mm) and supports fixed-point arithmetic. Core voltage is 1.25 V, while I/O voltages are 2.50 V and 3.30 V. It includes dual DMA controllers, SPI, UART, and PPI interfaces for multimedia and industrial applications.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix '5A' against the manufacturer's current ordering guide to confirm pinout, temperature range, and RoHS compliance status. Ensure the 256-CSPBGA package dimensions match the target PCB footprint. Confirm lead-free soldering profiles align with the component's moisture sensitivity level.

Digital Signal Processor Dsp Selection Notes

Select this model when a 533 MHz clock speed is required within the Blackfin family. Compare against higher-frequency variants like the 600 MHz or 756 MHz versions if performance demands exceed this specification. Verify that the 256-ball CSPBGA package is compatible with the assembly process compared to the 297-ball PBGA option.

Digital Signal Processor Dsp Part Context

This part belongs to the ADSP-BF561 Blackfin family, which introduced symmetric multiprocessing capabilities to the Blackfin architecture. It targets high-performance embedded signal processing tasks requiring parallel execution of code streams across two cores.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements include other ADSP-BF561 variants with different clock speeds or packages, such as ADSP-BF561SBB600. Verify software compatibility and pin assignments before substitution.
