- Medical equipment requiring precise analog signal acquisition
Procurement Notes
Verify the specific suffix 'CTUT' against official Microchip documentation to confirm tape-and-reel packaging and moisture sensitivity level. Ensure compatibility with existing PCB footprints for the TQFP-100 package. Cross-reference RoHS compliance status with current regulatory requirements before procurement.
Selection Notes
Select this component when a balance of processing power and peripheral richness is required in a compact form factor. The 120 MHz Cortex-M4F core provides sufficient performance for complex algorithms while maintaining energy efficiency. Consider the 512 kB Flash capacity for firmware size requirements and the extensive I/O count for system integration flexibility.
Part Context
This part belongs to the SAM D51 series, designed for cost-sensitive applications requiring ARM Cortex-M4F performance. It shares architectural similarities with the ATSAME51 series but lacks certain automotive-grade certifications found in higher-tier models. The P19 variant specifically denotes the pin count and memory configuration within the J19/N19/P19 family structure.
Replacement Considerations
ATSAMD51P19A-AU serves as a tray-packaged alternative with identical electrical characteristics. ATSAMD51N19A-AUT offers a different package option. Verify pin-to-pin compatibility and software library support when substituting.
