ATSAMD21E16B-AUT

Overview

The ATSAMD21E16B-AUT is a 32-bit ARM Cortex-M0+ microcontroller from the SAM D21E series, designed for functional safety applications. It features 64 kB of Flash program memory and 8 kB of SRAM data memory. The device operates with a maximum clock frequency of 48 MHz and supports an input/output count of 26 I/O lines. It includes a 12-bit ADC with 10 channels and a 10-bit DAC. The unit is housed in a 32-TQFP package and complies with AEC-Q100 standards.

Feature Summary

Integrated Functional Safety (FuSa) capabilities aligned with automotive reliability requirements.
Advanced analog subsystem featuring high-resolution 12-bit ADC and 10-bit DAC converters.
Comprehensive peripheral set including USB, DMA, I2S, and multiple communication interfaces.

Applications

Automotive electronic control units requiring AEC-Q100 qualification.
Industrial automation systems utilizing functional safety protocols.
Battery management systems within electric vehicle architectures.

Procurement Notes

Verify the specific suffix 'AUT' corresponds to the Tape and Reel packaging configuration rather than Tray delivery. Confirm that the Functional Safety designation matches the intended application's safety integrity level requirements. Ensure the operating temperature range aligns with the specified -40°C to +85°C ambient limits for the target environment.

Selection Notes

Select this component when automotive-grade reliability and functional safety certification are mandatory. The SAMD21E variant offers enhanced diagnostic features compared to standard SAMD21 models. Consider the 64 kB Flash capacity against project code size requirements before finalizing the selection.

Part Context

This part belongs to the SAM D21E family, which extends the standard SAM D21 line with functional safety features. It shares the Cortex-M0+ core architecture but adds hardware-based safety mechanisms. The E-series designation specifically indicates compliance with automotive quality standards.
