Procurement Notes
Verify the specific suffix CFNT confirms the 144-UFBGA package and tape-and-reel shipping format. Confirm the A variant denotes standard commercial specifications. Cross-reference the manufacturer part number against official Microchip documentation to ensure authenticity and correct revision level before integration into production designs.
Selection Notes
Select this component when a balance of high computational throughput and rich connectivity is required in a compact footprint. The UFBGA package suits dense PCB layouts. Ensure design requirements align with the 300MHz clock speed and available GPIO count. Consider thermal management for the BGA package under full load conditions within the specified temperature range.
Part Context
This MCU belongs to the SAM E70 family, designed for performance-oriented embedded applications. It shares architectural similarities with the SAM S70 but focuses on cost-effective industrial solutions. The device leverages the Cortex-M7 architecture to deliver efficient code execution and advanced signal processing capabilities for complex control loops.
Replacement Considerations
ATSAME70Q20A-AN offers identical electrical specifications in a 144-LQFP package. ATSAMS70Q20A-CFN provides similar core features in a UFBGA package but belongs to the SAM S70 series. Verify pin compatibility and software library support when substituting these variants.
