- Provides flexible Serial Communication (SERCOM) peripherals configurable as standard communication interfaces.
- Includes analog peripherals such as a 12-bit ADC and a 10-bit DAC for signal processing.
- Features low-power operation modes including Idle, Sleep, Standby, and HIB to optimize energy consumption.
Applications
- Industrial control systems requiring robust peripheral connectivity
- Consumer electronics utilizing USB communication capabilities
- Battery-powered devices leveraging low-power management features
- Sensor interface nodes using integrated ADC and DAC functions
Procurement Notes
Verify the specific suffix 'AN' against official Microchip documentation to confirm the 48-TQFP package and extended temperature rating. Ensure compatibility with required voltage levels and pin configurations during sourcing. Cross-reference datasheet revisions to account for any errata or design changes affecting functionality.
Selection Notes
Select this model when a balance of processing power and peripheral density is required within a compact footprint. The inclusion of USB hardware support makes it suitable for communication-heavy applications. Consider the 48MHz speed and memory size relative to software complexity. Verify that the TQFP package aligns with PCB layout constraints and thermal requirements.
Part Context
This component belongs to the SAM D20 family of microcontrollers, designed for low-power applications. It shares architectural similarities with other SAMD series devices but offers specific memory and peripheral configurations tailored for cost-sensitive embedded solutions. The family emphasizes ease of use through comprehensive software frameworks and development tools.
Replacement Considerations
ATSAMD20G17A-AU: Same core and memory, different QFN package. ATSAMD20G17A-MN: Same core and memory, different QFN package. ATSAMD20G17A-MUT: Same core and memory, different QFN package. Verify pinout and package dimensions before substitution.
