Procurement Notes

Verify the specific suffix 'BA' indicates the industrial temperature grade (-40°C to +85°C) compared to other variants. Confirm the package type is 100-LQFP. Ensure compatibility with existing board layouts for the 14x14 mm footprint. Check for RoHS compliance documentation if required by regional regulations.

Selection Notes

Select this MCU when a balance of high performance and low power consumption is required. The Cortex-M4 core offers DSP instructions suitable for complex algorithms. Consider the 1 MB Flash size for large application codebases. Evaluate pin count requirements against the 79 available I/Os in the 100-pin package.

Part Context

This component is part of the SAM4N family, designed for cost-sensitive applications requiring ARM Cortex-M4 performance. It shares architectural similarities with the SAM4S series but focuses on lower pin counts and reduced peripheral sets. The SAM4N series targets embedded applications where power efficiency and code density are critical design factors.

Replacement Considerations
