ATSAMD21E17D-MUT

Overview

The ATSAMD21E17D-MUT is a 32-bit ARM Cortex-M0+ microcontroller from the SAM D21 series, designed for industrial applications. It features 128 kB of Flash program memory and 16 kB of SRAM data RAM. The device operates within a voltage range of 1.62 V to 3.63 V and supports a maximum clock frequency of 48 MHz. It includes a 12-bit ADC, a 10-bit DAC, and 26 general-purpose I/O pins. Packaged in a 32-VQFN format, it meets AEC-Q100 qualification standards and functions reliably between -40°C and +85°C.

Feature Summary

• AEC-Q100 qualified for automotive-grade reliability
• Integrated advanced analog peripherals including 12-bit ADC and 10-bit DAC
• Supports multiple communication interfaces such as SPI, I2C, USART, and LIN

Applications

• Industrial control systems requiring functional safety compliance
• Automotive electronic modules meeting AEC-Q100 standards
• Low-power embedded devices operating on limited voltage supplies

Procurement Notes

Verify the specific suffix 'MUT' corresponds to the 32-VQFN package and industrial temperature range during sourcing. Confirm RoHS compliance status through official Microchip documentation. Ensure compatibility with existing PCB footprints for the VQFN-32 form factor before procurement.

Selection Notes

Select this component when AEC-Q100 certification is mandatory for the target application. Choose this part over non-qualified variants if automotive or high-reliability industrial environments are required. Verify that the 128 kB Flash and 16 kB RAM capacities align with firmware size requirements.

Part Context

This MCU belongs to the SAM D21 family, which utilizes the ARM Cortex-M0+ core. The E-series designation typically indicates specific memory configurations and package options within the broader SAM D21 portfolio. It shares architectural similarities with other D21 variants but differs in peripheral counts and storage capacity.

Replacement Considerations

ATSAMD21E17D-AUT serves as a pin-compatible alternative in TQFP packaging.
