ATSAMD20G17A-MUT

Overview

The ATSAMD20G17A-MUT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, belonging to the SAM D20G series. It features 128 KB of flash program memory and 16 KB of SRAM. The device operates at a maximum frequency of 48 MHz with a supply voltage range of 1.62 V to 3.6 V. It includes one 12-bit ADC with 14 channels and one 10-bit DAC. The component is housed in a 48-QFN (7x7 mm) package and supports interfaces including I2C, SPI, UART/USART, and USB.

Feature Summary

• Integrates an ARM Cortex-M0+ processor for efficient low-power embedded control
• Includes built-in analog-to-digital conversion and digital-to-analog conversion capabilities
• Supports multiple serial communication protocols via Serial Communication (SERCOM) modules
• Features internal oscillators and power management peripherals such as brown-out detection

Applications

• Low-power wearable devices requiring compact form factors
• Battery-operated consumer electronics utilizing USB connectivity
• Industrial sensor nodes using SERCOM-based communication interfaces
• General-purpose embedded control systems within specified temperature ranges

Procurement Notes

Verify the specific suffix 'MUT' corresponds to the 48-QFN 7x7mm package and tape-and-reel orientation when sourcing. Confirm that the operating voltage requirements align with the 1.62V to 3.6V specification rather than the wider 2.7V-5.5V range found in other variants like the AU version. Ensure compatibility with development tools supporting the SAM D20 family architecture.

Selection Notes

Select this model when a QFN footprint is required instead of TQFP options available in the same series. It is suitable for designs needing integrated USB functionality without external transceivers. Consider the 48MHz speed limit and 128KB memory capacity against application demands. Verify pinout compatibility if replacing older Atmel-branded components with identical specifications.

Part Context

This component is part of the Microchip SAM D20 family, which utilizes the ARM Cortex-M0+ core for energy-efficient processing. The G-series designation typically indicates specific peripheral configurations and package types compared to J-series variants. It succeeds earlier Atmel SAMD20 products following the company acquisition, maintaining binary compatibility with existing software frameworks.

Replacement Considerations

ATSAMD20G17A-AU offers identical electrical specifications but uses a 48-TQFP package. ATSAMD20J17A-MUT provides the same package but includes additional ADC channels. Cross-checking pin assignments and peripheral availability is essential when substituting these models.
