Procurement Notes

Verify the specific ordering suffix against the manufacturer's current data sheet to confirm package type and speed grade. Confirm that the component meets the required AEC-Q100 automotive reliability standards for the intended application environment.

Selection Notes

Select this model when a 400 MHz SHARC processor with 5 Mbits of RAM is required in an 88-lead LFCSP package. Ensure the design accommodates the 1.1 V core voltage and 3.3 V I/O requirements. Verify compatibility with existing SHARC family codebases if migrating from other models.

Part Context

This component belongs to the ADSP-2148x family of SHARC processors. It shares architectural similarities with the ADSP-21486 and ADSP-21489 but is distinguished by its specific memory size, package option, and automotive qualification status.

Replacement Considerations

Direct replacements include other ADSP-2148x variants such as the ADSP-21486 or ADSP-21489, provided the pinout and memory requirements match. Cross-family migration to ADSP-2146x or ADSP-2147x may require software adaptation.
