Procurement Notes

Verify the specific suffix 'D3' against official documentation to confirm silicon revision or package variant details. Ensure compatibility with required operating temperatures and voltage levels before integration into final designs.

Selection Notes

Select this component for applications requiring robust OS support and rich user interfaces. Consider the integrated peripherals like Ethernet and USB when designing connectivity solutions without needing external controllers.

Part Context

Part of the AM1802 family, designed as a low-power applications processor. It targets OEMs and ODMs seeking high processing performance and flexibility through a fully integrated mixed processor solution based on the ARM9 architecture.

Replacement Considerations

Check for compatible ARM9-based processors from Texas Instruments such as the AM1806 series if higher clock speeds or additional features are required.
