- Integrated Functional Safety (FuSa) capabilities compliant with automotive standards
- Full-speed USB peripheral with dedicated DMA controller for efficient data transfer
- Multiple Serial Communication Interface (SERCOM) modules supporting various protocols
- Advanced analog peripherals including high-resolution ADCs and comparators
Applications
- Automotive body electronics and lighting control systems
- Industrial controllers requiring functional safety certification
- Consumer devices with USB connectivity requirements
- Smart home appliances with LINbus interface needs
Procurement Notes
Verify the specific suffix 'MU' corresponds to the 48-VFQFN package with exposed thermal pad. Confirm the 'A' revision indicates the functional safety variant. Check RoHS compliance status against current regulatory requirements. Ensure ESD handling procedures are followed due to moisture sensitivity classification. Validate that the intended application environment falls within the specified operating temperature range.
Selection Notes
Select this component when functional safety certification is required for automotive or industrial applications. Choose over standard SAMD21 variants if AEC-Q100 qualification is necessary. Consider the 48-QFN package for compact designs requiring thermal dissipation through the exposed pad. Evaluate pin count availability against system I/O requirements before finalizing the selection.
Part Context
This part belongs to the SAM D21G family, which is optimized for functional safety applications. It shares architectural similarities with other SAM D21 devices but includes enhanced reliability features. The G-series designation specifically denotes automotive-grade qualification. It complements the broader Microchip portfolio by providing a cost-effective solution for safety-critical embedded control tasks.
Replacement Considerations
ATSAMD21G17A-AU offers identical electrical specifications in a 48-TQFP package. ATSAMD21G17A-MUT provides the same functionality in tape-and-reel packaging. Verify pin compatibility and thermal performance differences when substituting packages.
