Procurement Notes

Verify the specific suffix 'CN' against official Microchip documentation to confirm environmental compliance status and regional availability constraints. Ensure the 100-TFBGA footprint matches your PCB design guidelines. Cross-reference the latest datasheet revision history for any pinout or electrical characteristic updates prior to finalizing procurement orders.

Selection Notes

Select this component when a balance of moderate memory capacity and high-speed processing is required in a compact form factor. The 100-pin TFBGA package suits applications with space constraints but sufficient I/O density needs. Consider the 1.08V minimum supply voltage for low-power design implementations compared to higher-voltage alternatives in the same family.

Part Context

This part belongs to the SAM S70 family, designed for high-performance embedded applications. It shares architectural similarities with the SAM E70 and V71 series but offers distinct memory configurations and peripheral sets tailored for cost-sensitive yet powerful microcontroller solutions. The N-series designation typically indicates specific memory and package combinations within the broader S70 portfolio.
