Procurement Notes

Verify the specific suffix 'D4' against official documentation to confirm silicon revision or packaging details. Ensure the ZWT package variant matches the required board layout. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a 456 MHz ARM926EJ-S processor is required with integrated SATA and USB connectivity. The ZWT package is suitable for applications needing a larger footprint than the ZCE variant. Verify that the system design supports the 1.3 V core voltage requirement for maximum performance operation.

Part Context

This part belongs to the Texas Instruments AM1808 Sitara family of low-power applications processors. It is designed for OEMs and ODMs to develop devices with robust OS support and rich user interfaces. The processor integrates mixed-signal peripherals to reduce system complexity and cost in embedded designs.

Replacement Considerations

AM1808BZWTD3 is a documented alternative within the same series.
