Procurement Notes

Verify the specific suffix 'CNT' against official Microchip documentation to confirm it denotes the Tape and Reel packaging variant for the ATSAMD20J15A series. Ensure the ordering part number matches the required package type and temperature grade. Confirm RoHS compliance status through the manufacturer's current datasheet or environmental declaration before procurement.

Selection Notes

Select this component when a low-power 32-bit MCU with an industrial temperature rating is required. The UFBGA-64 package offers high pin density suitable for compact designs. Consider the 48 MHz performance limit and 32 kB memory size relative to application complexity. Verify that the 1.62 V to 3.63 V supply range aligns with the system power architecture.

Part Context

This part belongs to the SAM D20 family of microcontrollers based on the ARM Cortex-M0+ core. The family provides a balance of performance and power efficiency for cost-sensitive applications. The 'J' designation typically indicates a specific pin count and peripheral set within the series, while the '15' often refers to the memory configuration.

Replacement Considerations

Cross-reference with other SAM D20 variants such as ATSAMD20J15A-AU or ATSAMD20J15A-MUT if different packaging is needed. Ensure functional compatibility regarding pinout and peripheral availability when substituting.
