Selection Guidelines

Choose this model if you need a cost-effective, low-power 32-bit MCU with integrated analog, digital, and multiple communication interfaces

Suitable for designs with up to 52 general purpose I/Os

For safety-critical or industrial environments, consider the integrated functional safety features

Select if your application requires surface mount assembly in moderate volume production (MSL 3)

Ensure your required working temperature is within -40°C to 85°C

Usage Considerations

Be aware moisture sensitivity (MSL 3); follow proper storage and soldering guidelines

Confirm voltage and current requirements for onboard components

Check any software or hardware dependencies for ARM Cortex-M0+ development

Observe ESD precautions during handling and assembly

Properly layout PCB for analog and high-speed signals due to integrated ADC/DAC and USB

Potential Equivalent/Replacement Models

Microchip offers a variety of SAM D21 models with different Flash, RAM, and package options, such as ATSAMD21J18A (256KB Flash) or ATSAMD21J15B (64KB Flash)

ATSAMD21G18A, ATSAMD21E18A: Same core, different pin count (48/32 pins)
