Procurement Notes
Verify the specific suffix 'AUR' corresponds to the Tape and Reel packaging format required for automated assembly processes. Confirm that the industrial temperature grade (-40°C to +85°C) meets the operational environmental requirements of the target application. Ensure compatibility with the 1.62 V to 1.9 V core voltage specifications during power supply design.
Selection Notes
Select this component when a balance of moderate Flash capacity and integrated USB functionality is required within a compact TFBGA footprint. Compare against other SAM3S variants if higher memory density or additional GPIO count is necessary. Consider the 64 MHz processing speed sufficient for real-time control tasks involving standard peripheral interfaces.
Part Context
This part belongs to the Microchip SAM3S series of 32-bit Flash microcontrollers. The series is designed for applications needing cost-effective performance with the ARM Cortex-M3 architecture. It shares pinout compatibility with other members of the family, facilitating scalable product development across different memory and package configurations.
Replacement Considerations
Consult official Microchip documentation for verified cross-reference part numbers. Substitutions must match the ARM Cortex-M3 core, 64 MHz speed, 64 kB Flash, and TFBGA-100 package constraints.
