Digital Signal Processor Dsp Procurement Notes

Verify component authenticity through authorized distributors as the part status may be obsolete. Confirm voltage requirements match system design, specifically the 3.3 V core and I/O levels. Check RoHS compliance status, as historical documentation indicates non-compliance for certain variants in this series. Ensure package compatibility with existing PCB footprints.

Digital Signal Processor Dsp Selection Notes

Select this component when a 24-bit fixed-point DSP with integrated memory is required. Compare against the DSPB56374AE variant for specific packaging or speed bin differences. Evaluate the 100 MHz clock limit against application throughput needs. Consider the 196-LBGA package dimensions if space constraints are critical.

Digital Signal Processor Dsp Part Context

This device is part of the DSP563xx family from Freescale Semiconductor, which succeeded Motorola's DSP line. The DSPB56374AF shares architectural similarities with other members like the DSP56371 but differs in I/O voltage compatibility, supporting 3.3 V instead of 5.0 V. It serves as a cost-optimized solution for embedded signal processing tasks.

Digital Signal Processor Dsp Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with the DSPB56374AE for potential pin-compatible alternatives within the same manufacturer portfolio.
