Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm package type and operating temperature range. Ensure compatibility with required voltage levels and interface protocols before integration. Confirm moisture sensitivity handling procedures are followed during assembly to maintain device reliability.
Selection Notes
Select this component when a balance of moderate memory capacity and low pin count is required. The 48-pin QFN package suits space-constrained designs. Consider the 48 MHz speed and 32 kB Flash for applications not requiring extensive data storage or higher processing throughput found in larger SAM3N variants.
Part Context
This part belongs to the SAM3N series of ARM-based microcontrollers designed for cost-sensitive and space-limited applications. It shares architectural similarities with other SAM3N devices but offers distinct memory and pin configurations tailored for specific integration needs within the broader Microchip portfolio.
Replacement Considerations
Consult official substitution guides for cross-referencing. Verify that alternative parts match the 48-QFN footprint and electrical specifications if direct replacement is necessary.
