Procurement Notes

Verify the specific suffix DNA100 against official datasheets to confirm the 1 GHz speed grade and commercial/industrial temperature rating. Ensure compatibility with required I/O voltage levels during board design. Confirm RoHS compliance status through manufacturer documentation before procurement.

Selection Notes

Select this model when a 1 GHz processing speed is required within the AM437x series. It shares the same BGA-491 footprint as lower-speed variants like the AM4377BZDNA80, facilitating potential pin-compatible upgrades. Verify that the application requires the specific PRU-ICS features and peripheral count provided by this silicon revision.

Part Context

This part belongs to the Texas Instruments Sitara AM437x series of microprocessors. These devices are designed for applications requiring high performance and rich connectivity. The series integrates various peripherals suitable for industrial and consumer electronics, sharing architectural similarities with other members like the AM4379 and AM4372.

Replacement Considerations

The AM4377BZDNA80 offers identical packaging and pinout but operates at 800 MHz. The AM4379BZDNA100 provides the same 1 GHz speed but may differ in peripheral availability or power characteristics. Verify electrical parameters before substitution.
