Procurement Notes

Verify the specific ordering suffix against the manufacturer's current data sheet to confirm package type and temperature range. Confirm availability status as supply conditions may vary. Ensure compatibility with existing design infrastructure before procurement.

Selection Notes

Select this model for designs requiring maximum memory capacity (5 Mbits RAM) within the ADSP-2147x family. The 88-lead LFCSP_VQ package offers a compact form factor suitable for space-constrained PCB layouts. Verify that the 300 MHz speed grade meets system timing requirements.

Part Context

This component belongs to the ADSP-2147x family, which shares source code compatibility with previous SHARC generations. The ADSP-21479 variant provides the highest memory configuration in the series, distinguishing it from the ADSP-21477 (2 Mbits RAM) and ADSP-21478 (3 Mbits RAM).

Replacement Considerations

ADSP-21479BCPZ1B02: Same specifications in a 196-ball CSP_BGA package.
