Procurement Notes

Verify the specific silicon revision and temperature grade required for your application against the datasheet specifications. Confirm that the ZKB package variant matches your PCB footprint requirements. Ensure power supply designs accommodate the distinct 1.2 V or 1.3 V core voltage rails depending on the target clock frequency.

Selection Notes

Select this component when a robust ARM9-based solution with integrated real-time processing and rich connectivity is needed. Consider the 456 MHz version if higher computational throughput is required, noting the increased power consumption compared to the 375 MHz option. Evaluate the available GPIO multiplexing options to ensure sufficient peripheral availability for the target design.

Part Context

This part belongs to the AM1707 Sitara family of low-power ARM microprocessors designed for OEMs and ODMs. It provides a fully integrated mixed-processor solution supporting robust operating systems and high-performance user interfaces. The architecture emphasizes flexibility and efficiency for embedded applications requiring significant processing power and diverse interface support.

Replacement Considerations

Consult the official product migration guide for compatible upgrades within the Sitara family. Verify pin-to-pin compatibility and software register mapping before substituting with other AM170x variants.
