ADSP-BF561SKB500

Digital Signal Processor Dsp Overview

The ADSP-BF561SKB500 is a dual-core Blackfin digital signal processor from Analog Devices, operating at a maximum clock frequency of 500 MHz. It integrates two symmetric cores within a 297-ball PBGA package. The architecture provides 328 KB of on-chip memory, comprising per-core L1 instruction and data SRAM/cache, scratchpad SRAM, and a shared 128 KB L2 SRAM. Key electrical parameters include a core voltage of 1.25 V and I/O voltages of 2.5 V or 3.3 V. The device supports fixed-point processing with a throughput of up to 2400 MMACS.

Digital Signal Processor Dsp Feature Summary

• Dual symmetric Blackfin cores running at 500 MHz
• 328 KB total on-chip memory (L1/L2 SRAM)
• 2400 MMACS computational throughput
• Integrated DMA controllers and video interfaces

Digital Signal Processor Dsp Applications

• Video encoding and decoding platforms
• Industrial motor control systems
• Telecommunications equipment

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'KB' against the official Analog Devices ordering guide to confirm pin compatibility and thermal specifications. Ensure the procurement source provides the Rev. F datasheet for accurate timing and electrical characteristics. Confirm RoHS compliance status prior to integration into final assemblies.

Digital Signal Processor Dsp Selection Notes

Select this model when a 500 MHz operating frequency is required instead of higher-speed variants. The 297-ball PBGA package is suitable for designs requiring specific board space constraints compared to the 256-ball CSP_BGA options. Verify that the system power supply can support the 1.25 V core voltage requirement.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-BF561 family of symmetric multiprocessors. It shares the same architectural foundation as other BF561 variants but is distinguished by its specific clock speed rating and package configuration. It is designed for multimedia and industrial applications requiring high-performance DSP capabilities.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same family include ADSP-BF561SKBCZ-5A and ADSP-BF561SBBZ500. Verify package dimensions and pin assignments before substitution, as CSP_BGA and PBGA footprints are not interchangeable.
