Procurement Notes

Verify the specific suffix WBSWZ402 against the manufacturer's current ordering guide to confirm package type and temperature grade. Confirm availability status as supply constraints may apply to this part number.

Selection Notes

Select this model for designs requiring high-throughput audio processing with low power consumption. Ensure the system design accommodates the 176-lead LQFP EPAD footprint and provides adequate thermal management for the exposed pad.

Part Context

This processor is part of the ADSP-2148x family, which includes the ADSP-21483, ADSP-21486, ADSP-21487, and ADSP-21488. All members share source code compatibility and similar peripheral architectures, differing primarily in memory size and clock speed.

Replacement Considerations

Other members of the ADSP-2148x family are pin-compatible. Verify if lower memory variants like the ADSP-21486 or ADSP-21487 meet the application requirements.
