Procurement Notes
Verify the specific suffix 'MUT' corresponds to the 64-QFN tape-and-reel packaging configuration. Confirm that the operating temperature range meets the -40°C to +85°C requirement for the intended environment. Ensure compatibility with the 2.7V to 5.5V supply voltage specifications during system design validation.
Selection Notes
Select this component when 128KB of program storage and 16KB of RAM are required alongside extensive analog input channels. The 64-pin QFN package suits designs needing high I/O density in a small footprint. Consider the 48MHz speed limit and lack of DMA if real-time data throughput constraints exist.
Part Context
This part belongs to the SAM D20 family, designed for cost-sensitive 32-bit applications. It shares architectural similarities with other SAMD20 variants but offers specific memory and pinout configurations. The device supports standard development tools like Atmel Studio and the Advanced Software Framework for streamlined integration.
FAQ
Does the ATSAMD20J17A-MUT support Direct Memory Access?
No, the datasheet specifications indicate that this specific model does not include a DMA controller.
What is the resolution of the integrated analog-to-digital converter?
The device features a 12-bit ADC with 20 available input channels.
