ATSAMD21E15B-AFT

Overview

The ATSAMD21E15B-AFT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, belonging to the SAM D21E Functional Safety series. It features 32KB of flash memory and 4KB of SRAM, operating at a maximum frequency of 48MHz. The device supports a supply voltage range of 1.62V to 3.6V and includes ten 12-bit ADC channels and one 10-bit DAC. Connectivity options include I2C, LINbus, SPI, USART, and USB interfaces. It is housed in a 32-TQFP package with an extended industrial temperature range of -40°C to 125°C.

Feature Summary

Functional Safety (FuSa) certified for automotive applications
AEC-Q100 qualified for reliability standards
Integrated analog peripherals including multiple ADCs and a DAC
Comprehensive digital communication interfaces including USB

Applications

Automotive body electronics systems
Industrial control modules requiring functional safety
Consumer devices needing robust MCU performance
Battery management system controllers

Procurement Notes

Verify the specific suffix 'AFT' confirms the 125°C temperature grade and TQFP packaging during sourcing. Confirm AEC-Q100 qualification status matches project requirements. Ensure compatibility with existing firmware binaries compiled for the SAM D21E family. Check for any recent production change notices affecting pinout or electrical characteristics.

Selection Notes

Select this component when functional safety certification is mandatory for the application. Choose over non-automotive variants if operation above 85°C is required. Consider the 32-TQFP package constraints for PCB layout. Evaluate memory size against application code complexity before finalizing selection.

Part Context

This part belongs to the SAM D21E series, which is Microchip's automotive-grade extension of the popular SAM D21 family. The E-series specifically targets functional safety applications, offering higher reliability than standard commercial parts. It shares architectural similarities with other SAM D21 variants but adds rigorous quality controls and qualification testing.
