ATSAMD20E15A-AUT

Overview

The ATSAMD20E15A-AUT is an ARM-based microcontroller from the SAM D20E series, featuring a Cortex-M0+ core operating at a maximum clock frequency of 48 MHz. It integrates 32 kB of Flash program memory and 4 kB of SRAM data memory within a 32-TQFP package. The device supports a supply voltage range of 1.62 V to 1.95 V and operates within a temperature range of -40°C to +85°C. Peripheral interfaces include I2C, SPI, and UART.

Feature Summary

• Integrates a 32-bit ARM Cortex-M0+ processor core for efficient code execution.
• Includes on-chip Flash memory for non-volatile program storage.
• Provides standard serial communication interfaces for peripheral connectivity.
• Operates within a specified industrial temperature range.

Applications

• General-purpose embedded control systems
• Low-power sensor interface nodes
• Simple human-machine interface controllers

Procurement Notes

Verify the specific suffix AUT indicates tape and reel packaging when sourcing components. Confirm the voltage range specification matches the target application requirements, as this variant specifies a maximum of 1.95 V. Ensure compatibility with the 32-TQFP footprint during PCB layout. Check for moisture sensitivity level requirements during assembly processing.

Selection Notes

Select this component for applications requiring a 32-bit ARM core with moderate memory capacity in a surface-mount package. Compare against other SAM D20 variants if higher voltage tolerance or different pin counts are needed. Consider the specific I/O count and peripheral availability relative to system design constraints.

Part Context

This part belongs to the Microchip SAM D20 family of microcontrollers based on the ARM Cortex-M0+ architecture. The E15 designation typically corresponds to specific memory configurations and package types within the series. The AUT suffix denotes the reel packaging format used for automated assembly processes.

Replacement Considerations

Direct substitutes may include other SAM D20E15 variants with compatible packages, such as ATSAMD20E15A-AU, provided voltage and environmental specifications align. Cross-family replacements require verification of pin compatibility and software migration efforts.
