Procurement Notes

Verify the specific suffix 'E80' against the official Texas Instruments datasheet to confirm the exact temperature range and packaging configuration. Ensure compatibility with required I/O voltage levels (1.5V, 1.8V, 3.3V) during system design. Confirm moisture sensitivity handling requirements are met for the PBGA-684 package before assembly.

Selection Notes

Select this component when a dedicated ARM Cortex-A8 processor with integrated peripherals is required for embedded applications. Consider the 800 MHz performance ceiling and available I/O count relative to system complexity. Evaluate power consumption constraints given the 1.1 V core voltage requirement and thermal dissipation needs for the PBGA-684 package in enclosed environments.

Part Context

This part belongs to the Texas Instruments Sitara AM387x series, designed for demanding embedded control and connectivity tasks. The series integrates a powerful processor core with rich peripheral sets to reduce external component count. The AM3871 variant specifically targets industrial and medical markets requiring robust processing capabilities and reliable long-term availability.

Replacement Considerations

Consult the official AM387x family comparison table for pin-compatible or functionally similar alternatives. Verify that any substitute maintains support for required interfaces such as PCIe and USB while matching the ARM Cortex-A8 architecture.
