Procurement Notes
Verify the specific suffix 'ANT' against official Microchip documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with required operating temperature ranges and check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement.
Selection Notes
Select this component when a balance of high computational performance and rich connectivity is required. The SAM E70 series is suitable for applications needing robust real-time processing alongside complex communication protocols. Evaluate memory requirements against the 512 KB flash limit and ensure the 144-pin package fits the design constraints.
Part Context
This part belongs to the SAM E70 family, designed for cost-sensitive applications requiring Cortex-M7 performance. It shares architectural similarities with the SAM S70 and SAM V70 series but offers a distinct peripheral mix optimized for industrial and commercial markets. The Q19 variant denotes specific memory and package configurations within this lineup.
Replacement Considerations
Consult Microchip's official cross-reference tools for verified substitutes. Potential alternatives within the same family include variants with different memory sizes or packages, such as ATSAME70Q21 or ATSAME70J19, provided pinouts and peripheral sets match the application requirements.
