Procurement Notes

Verify the specific suffix 'MUT' confirms the tape and reel packaging format required for automated assembly processes. Confirm the operating temperature grade corresponds to the industrial specification of up to 105°C. Ensure the voltage range aligns with the system's power supply design constraints before finalizing procurement orders.

Selection Notes

Select this model when a compact QFN-48 footprint is necessary alongside 38 available I/O lines. Choose this variant over other SAMD20 series parts if the application specifically requires 16 kB of Flash memory and 14 ADC channels. Consider the 48 MHz processing speed sufficient for real-time control tasks within the specified thermal envelope.

Part Context

This component belongs to the Microchip SAM D20 series of 32-bit flash microcontrollers based on the ARM Cortex-M0+ core. The series is designed for applications demanding low power consumption and high performance. The SAMD20 family offers various pin counts and memory configurations to suit different embedded system requirements.

Replacement Considerations

ATSAMD20G14A-MU: Identical electrical specifications but supplied in tray packaging instead of tape and reel.
