Procurement Notes

Verify the specific suffix designation against official documentation to confirm performance grades and packaging variations. Confirm RoHS compliance status and moisture sensitivity levels prior to assembly planning. Ensure compatibility with required development kits such as TMDXEVM3358 for initial validation. Check for any recent product change notifications regarding marking or wafer fabrication sites.

Selection Notes

Select this component when an ARM Cortex-A8 architecture is required for applications needing up to 800 MHz processing speed. Verify that the PBGA-324 package fits the board layout constraints. Ensure the design accommodates the 1.26 V core voltage and 1.8/3.3 V I/O requirements. Consider the thermal dissipation needs for operation up to 105°C in enclosed industrial environments.

Part Context

This part belongs to the Texas Instruments Sitara AM335x series of microprocessors. These devices are designed for cost-sensitive embedded applications requiring Linux or RTOS support. The series shares common peripheral sets but varies in clock speeds and memory configurations.
