ATSAMC20G18A-MUT

Overview

The ATSAMC20G18A-MUT is a 32-bit microcontroller from the Microchip SAM C20 series, built on the ARM Cortex-M0+ core. It features 256 kB of Flash program memory and 32 kB of SRAM. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports a maximum clock frequency of 48 MHz. It includes an analog-to-digital converter with 12-bit resolution and 12 channels. The component is housed in a 48-lead QFN package (7x7 mm) and is rated for industrial temperatures between -40°C and +85°C.

Feature Summary

• Supports 5V operation alongside standard 3.3V logic levels for flexible system integration.
• Includes automotive-grade AEC-Q100 qualification for reliability in demanding environments.
• Integrates multiple communication interfaces including LIN, I2C, SPI, and USART.
• Features advanced analog peripherals such as a 12-bit ADC and a 10-bit DAC.

Applications

• Automotive body electronics and comfort modules
• Industrial control systems requiring robust communication protocols
• Consumer appliances with 5V power domains
• Battery-powered devices utilizing low-power modes

Procurement Notes

Verify the specific suffix 'MUT' corresponds to the 48-QFN 7x7mm package and tape-and-reel orientation. Confirm that the AEC-Q100 qualification status meets your project's automotive reliability standards. Check for any recent Product Change Notifications regarding assembly sources or material composition updates. Ensure compatibility with your chosen programming interface and debug probe requirements.

Selection Notes

Select this model when 5V tolerance is required without external level shifters. Compare against the ATSAMD20G18A if automotive certification is not needed, noting the voltage range difference. Consider the ATSAMC20G17A if reduced memory capacity suffices for the application. Evaluate pin count availability against the 38 available I/O lines for peripheral connectivity needs.

Part Context

This component belongs to the SAM C20 family, which extends the SAM D20 architecture with added automotive qualifications and enhanced analog features. It shares the same core processor but differs in voltage specifications and peripheral configurations compared to non-automotive variants. The family targets applications needing reliable performance in electrically noisy or temperature-variable environments.

Replacement Considerations

ATSAMD20G18A-MUT offers similar functionality but lacks AEC-Q100 qualification and has a different voltage range. ATSAMC20G17A-MUT provides lower memory capacity. Verify pinout compatibility and software library support before substituting any alternative part numbers.
