- Integrated full-speed USB device and embedded host controller
- Advanced analog peripherals including multi-channel ADC and DAC
- Configurable Serial Communication Modules (SERCOM)
Applications
- Automotive infotainment systems
- Industrial control units
- Consumer electronics devices
- Smart metering equipment
Procurement Notes
Verify the specific suffix 'MUT' corresponds to the 48-QFN package variant when sourcing. Confirm RoHS compliance status as per current manufacturer documentation. Ensure the functional safety qualification aligns with your system requirements. Check for any lead-free or green material certifications required by your manufacturing process. Validate the operating temperature range against your environmental specifications.
Selection Notes
Select this model for applications requiring Functional Safety certification within the SAM D21 family. Compare pin counts and memory sizes against other G-series variants if fewer resources are needed. Consider the TQFP package option if surface mount technology constraints favor that form factor. Evaluate the J-series models for higher I/O counts if peripheral expansion is necessary.
Part Context
This component belongs to the Microchip SAM D21 series, which utilizes the ARM Cortex-M0+ architecture. The series is designed for low-power, high-performance applications. The G-series specifically targets general-purpose and automotive markets. It offers easy migration paths between different pin counts and memory configurations within the same ecosystem.
Replacement Considerations
ATSAMD21G17A-AFT provides the same electrical specifications in a 48-TQFP package. ATSAMD21J17A-MF offers identical core performance but with increased I/O count in a 64-QFN package.
