ATSAMD21E15B-AU

Overview

The ATSAMD21E15B-AU is a 32-bit microcontroller based on the ARM Cortex-M0+ core, part of the SAM D21E Functional Safety series. It features 32KB of Flash memory and 4KB of SRAM. The device operates at a maximum frequency of 48MHz with a supply voltage range of 1.62V to 3.63V. It includes ten 12-bit ADC channels and one 10-bit DAC. Connectivity options include I2C, SPI, USART, LINbus, and USB interfaces. The component is housed in a 32-TQFP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

Integrated AEC-Q100 qualification for automotive functional safety applications
Supports USB device functionality with integrated transceiver
Includes advanced analog peripherals such as high-resolution ADC and DAC

Applications

Automotive body electronics and lighting control
Industrial sensor nodes requiring functional safety compliance
Consumer devices with USB connectivity requirements

Procurement Notes

Verify the specific suffix 'AU' corresponds to the 32-TQFP package and industrial temperature grade during sourcing. Confirm that the AEC-Q100 qualification status is active for this specific revision. Ensure compatibility with existing PCB footprints for the TQFP-32 form factor before finalizing procurement orders.

Selection Notes

Select this model when automotive functional safety certification is mandatory alongside USB capabilities. Compare against non-automotive variants if cost sensitivity outweighs safety requirements. Consider pin count constraints as the 32-pin package limits available GPIO compared to larger packages in the same family.

Part Context

This component belongs to the SAM D21E family, which extends the standard SAM D21 line with enhanced reliability features for automotive use. It shares architectural similarities with other SAM D21E variants but differs in memory size and package options. The E-series designation specifically indicates adherence to stricter automotive quality standards.

FAQ

Does the ATSAMD21E15B-AU support CAN communication?

No, the datasheet specifies support for I2C, SPI, USART, LINbus, and USB. CAN interface is not listed among the peripheral connections for this specific part number.
