Procurement Notes

Verify the specific suffix DNA against the official datasheet to confirm the exact speed grade and package variant. Ensure compatibility with required I/O voltage levels during board design. Confirm moisture sensitivity level handling procedures are followed according to JESD22-B113 standards before assembly.

Selection Notes

Select this model when a 1 GHz processing speed is required within the AM437x series. Compare against AM4376BZDNA80 if lower power consumption at 800 MHz is sufficient. Consider the AM4379BZDNA100 if higher performance or additional features are needed beyond the AM4376 specifications.

Part Context

This component belongs to the Texas Instruments Sitara AM437x processor family, designed for applications needing a balance of processing power and peripheral integration. It shares architectural similarities with other AM437x variants but differs in clock speed and specific feature availability. The part is intended for embedded systems requiring robust connectivity and real-time capabilities.

Replacement Considerations

AM4376BZDNA80 offers identical functionality at 800 MHz. AM4379BZDNA100 provides enhanced performance within the same package. Verify pinout and software compatibility before substituting with any alternative part number.
