Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix '2A' against the manufacturer's current ordering guide to confirm package type and temperature range specifications. Ensure compatibility with development tools supporting the SHARC architecture and VISA instruction set before procurement.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high throughput in audio or signal processing tasks. Compare internal memory sizes with the ADSP-21477 (2 Mbits RAM) and ADSP-21479 (5 Mbits RAM) variants to match system requirements. Confirm that the 100-lead LQFP package meets board space constraints, noting it lacks an external port interface.

Digital Signal Processor Dsp Part Context

This component is part of the ADSP-2147x family, which shares source code compatibility with previous SHARC generations like the ADSP-2126x and ADSP-2136x. The family offers varying memory configurations and peripheral sets, with the ADSP-21478 positioned between the lower-memory ADSP-21477 and the higher-memory ADSP-21479.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same package include the ADSP-21477KSWZ-2A (lower memory) and ADSP-21479KSWZ-2A (higher memory). Verify pinout compatibility and memory mapping differences when substituting.
