Overview
The ATSAMDA1G16B-ABT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, belonging to the SAM DA1 series designed for functional safety applications. It features 16KB of Flash memory and 4KB of SRAM, operating at a maximum frequency of 48MHz. The device supports an operating voltage range of 1.62V to 3.6V and includes integrated peripherals such as ADCs, DACs, and communication interfaces including I2C, SPI, UART/USART, and USB. It is qualified under AEC-Q100 standards for automotive use.
Feature Summary
- Functional Safety (FuSa) design compliant with ISO 26262 ASIL B requirements
- Automotive qualification certified under AEC-Q100 standards
- Integrated USB Full-Speed controller for connectivity
- Low-power operation with multiple sleep modes
Applications
- Automotive body electronics systems
- Instrument clusters and displays
- Door control modules
- Seat adjustment controllers
Procurement Notes
Verify the specific suffix ABT corresponds to the required package type and temperature grade. Confirm AEC-Q100 qualification status for your specific application environment. Check for any recent Product Change Notifications (PCNs) affecting pinout or electrical characteristics. Ensure compatibility with existing firmware libraries for the SAM DA1 family.
Selection Notes
Select this component when automotive functional safety certification is mandatory. Compare against ATSAMD21G series if FuSa features are not required. Consider power consumption requirements across different operating modes. Verify peripheral availability matches interface needs such as CAN or LIN if present in later variants.
Part Context
This part belongs to the Microchip SAM DA1 family, which extends the popular SAM D21 architecture with added functional safety features. It targets automotive applications requiring high reliability. The family shares software compatibility with SAM D21 but includes additional safety mechanisms like memory protection and error detection circuits.
Replacement Considerations
ATSAMD21G16B-AFT serves as a non-safety counterpart. ATSAMD21G16B-MU offers a different package option without safety features. Direct replacement requires verifying that safety compliance is not critical for the target application.
