Procurement Notes
Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 100-TQFP configuration. Confirm that the selected variant meets all functional requirements for the target application environment.
Selection Notes
Select this component when a balance of processing performance and low power consumption is required. The inclusion of dedicated peripherals like the LCD controller and capacitive touch module reduces external component count. Consider the available I/O lines and memory size relative to application complexity.
Part Context
This part belongs to the SAM4L series of microcontrollers designed for low-power applications. The series utilizes the ARM Cortex-M4 core and integrates advanced power management features. It is distinct from other SAM4 variants by its specific focus on energy efficiency and integrated display and touch control capabilities.
Replacement Considerations
Consult official substitution lists for verified alternatives. Cross-reference pinouts and electrical characteristics before replacing components in existing designs.
