Procurement Notes
Verify the specific package type and temperature range against project requirements. Confirm that the ordering suffix matches the desired pin count and thermal characteristics. Ensure compatibility with existing development tools and software frameworks provided by Microchip Technology for the SAM4L series.
Selection Notes
Consider the trade-off between processing speed and power consumption when configuring voltage scaling. Evaluate the available GPIO lines and peripheral channels to ensure sufficient connectivity for the application. Check if the integrated LCD controller or capacitive touch features meet specific user interface needs without external components.
Part Context
This component belongs to the SAM4L series of microcontrollers, designed for low-power applications. It shares architectural similarities with other SAM4L variants but differs in memory size and peripheral availability. The series is known for its efficiency and integration of advanced features like QTouch and USB capabilities within a compact form factor.
Replacement Considerations
Direct substitutes may include other members of the SAM4L family with compatible pinouts and memory configurations. Verify electrical specifications and peripheral sets to ensure functional equivalence. Consult official documentation for cross-referencing part numbers within the same manufacturer's portfolio.
