ATSAMD20E14A-MUT

Overview

The ATSAMD20E14A-MUT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, belonging to the SAM D20E family. It integrates 16KB of flash memory and 2KB of SRAM. The device operates at a maximum clock frequency of 48MHz and supports a supply voltage range of 1.62V to 3.63V. It features an internal oscillator and provides 25 general-purpose I/O pins. Connectivity includes I2C, SPI, and UART/USART interfaces. The component is housed in a 32-VQFN package with dimensions of 5x5mm.

Feature Summary

• Integrates an ARM Cortex-M0+ processor core for efficient code execution
• Includes built-in analog-to-digital conversion capabilities with multiple channels
• Supports standard serial communication protocols for peripheral interfacing
• Features low-power operation suitable for battery-driven applications

Applications

• Low-cost embedded control systems
• Simple sensor interface modules
• Basic data logging devices
• Consumer electronics with limited pin count requirements

Procurement Notes

Verify the specific suffix 'MUT' corresponds to the 32-VQFN (5x5) package configuration. Confirm that the operating voltage range aligns with the target system's power supply rails. Check for any recent product change notifications regarding assembly sites or material composition updates. Ensure compatibility with existing PCB footprints designed for this specific QFN variant.

Selection Notes

Select this model when a compact footprint is required alongside basic processing needs. It serves as a cost-effective alternative to larger packages like TQFP if board space is constrained. Consider the limited I/O count and memory size against application complexity. Verify that the VQFN thermal dissipation characteristics meet the design's thermal management requirements.

Part Context

This component is part of the Microchip SAM D20E series, which targets entry-level applications requiring small form factors. The 'E' designation typically indicates specific pinout or feature variations within the broader SAM D20 family. It shares architectural similarities with other SAM D20 variants but differs in memory capacity and package type.

Replacement Considerations

ATSAMD20E14A-MU offers identical electrical specifications but utilizes a QFN-32 tray package instead of the tape-and-reel VQFN format. ATSAMD20G14A-MUT provides increased memory resources while maintaining the same package style.
