ATSAMD21E16L-MF

Overview

The ATSAMD21E16L-MF is a 32-bit microcontroller based on the ARM Cortex-M0+ core, designed for automotive applications with AEC-Q100 qualification. It features 64KB of flash memory and 8KB of SRAM. The device operates at a maximum frequency of 48MHz within a supply voltage range of 1.6V to 3.6V. It supports an extended industrial temperature range from -40°C to +125°C and is housed in a 32-pin QFN package.

Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards
• Integrated functional safety capabilities compliant with FuSa requirements
• Advanced analog peripherals including multiple ADC channels and a DAC

Applications

• Automotive body electronics systems
• Functional safety-critical embedded control modules
• Industrial automation controllers requiring wide temperature operation

Procurement Notes

Verify the specific suffix 'MF' corresponds to the 32-QFN package and 125°C temperature grade in official Microchip documentation. Confirm AEC-Q100 certification status and Functional Safety (FuSa) compliance details directly from the datasheet before integration into safety-rated designs.

Selection Notes

Select this component when automotive qualification and functional safety are mandatory. Ensure the design accommodates the 32-QFN footprint and thermal characteristics. Compare against other SAM D21E variants if different memory sizes or package options are required for the specific application constraints.

Part Context

This part belongs to the SAM D21E series, which focuses on low-power performance combined with automotive-grade robustness. It shares the Cortex-M0+ architecture with other SAM D21 models but distinguishes itself through its specific memory configuration and extended temperature rating suitable for harsh environments.

Replacement Considerations

ATSAMD21E16L-AF offers identical specifications in a 32-TQFP package.
