Overview
The ATSAMDA1G15B-MBT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at a maximum frequency of 48 MHz. It features 32 KB of in-system programmable Flash memory and 4 KB of SRAM. The device supports a supply voltage range of 2.7 V to 3.63 V and operates within an industrial temperature range of -40°C to +105°C. It includes 14-channel 12-bit ADCs and one 10-bit DAC. Connectivity options include I2C, SPI, UART/USART, and USB interfaces. The component is housed in a 48-QFN (7x7) package with 38 available I/O pins.
Feature Summary
- Automotive-grade functional safety qualification compliant with ISO 26262 standards
- Integrated USB 2.0 full-speed device controller for communication applications
- On-chip debug system supporting In-System Programming and debugging via standard interfaces
Applications
- Automotive body electronics and lighting control modules
- Industrial sensor nodes requiring functional safety compliance
- Consumer devices utilizing USB connectivity for data transfer or charging management
Procurement Notes
Verify the specific suffix MBT corresponds to the 48-QFN package and tape-and-reel orientation required for your assembly line. Confirm that the automotive qualification status meets the specific ASIL requirements of your target application. Ensure compatibility with the 2.7V to 3.63V supply domain before finalizing the bill of materials.
Selection Notes
Select this component when ISO 26262 functional safety certification is mandatory for the end product. It is suitable for designs requiring integrated USB capabilities alongside robust industrial temperature performance. Compare against non-automotive SAMD series parts if safety certification is not required to optimize cost.
Part Context
This part belongs to the Microchip SAM DA1 family, which is specifically designed for automotive applications meeting ISO 26262 functional safety requirements. It shares architectural similarities with the SAM D20 and SAM D21 families but adds automotive-specific certifications and reliability features. The device targets high-reliability embedded systems in transportation and industrial sectors.
Replacement Considerations
Direct pin-to-pin replacements within the same package are limited due to the specific automotive qualification. Non-automotive equivalents like the ATSAMD20G15B-MUT lack the required safety certification. Verify if the ATSAMD21E15B-MUT serves as a functional substitute if automotive qualification is not strictly enforced.
