ATSAMC20G17A-MUT

Overview

The ATSAMC20G17A-MUT is an ARM Cortex-M0+ microcontroller from the Microchip ATSAMC20 series, housed in a 48-pin VQFN package. It features 128 kB of Flash program memory and 16 kB of SRAM data memory on a 32-bit bus. The device operates at a maximum clock frequency of 48 MHz with a supply voltage range of 2.7 V to 5.5 V. It includes 38 general-purpose I/Os, twelve 12-bit ADC channels, and five timers/counters. Certified under AEC-Q100 for automotive applications, it supports interfaces including LIN, I2C, PMBus, SPI, and USART within an operating temperature range of -40°C to +85°C.

Feature Summary

• Automotive-grade reliability certified by AEC-Q100 standards for robust performance in vehicle environments.
• Integrated advanced analog peripherals including a high-resolution 12-bit ADC with multiple input channels.
• Supports diverse communication protocols such as LIN, I2C, PMBus, SPI, and USART for versatile connectivity.
• Delivers efficient processing via the ARM Cortex-M0+ core optimized for low-power embedded control tasks.

Applications

• Automotive body electronics and sensor interface modules
• Industrial control systems requiring LIN or PMBus communication
• Consumer appliances with multi-channel analog signal acquisition needs

Procurement Notes

Verify the specific suffix 'MUT' corresponds to the 48-VQFN package and tape-and-reel shipping format. Confirm that the AEC-Q100 qualification status meets your project's automotive grade requirements. Ensure compatibility with the 2.7V to 5.5V supply voltage range for your power design. Check for any recent product change notifications regarding pinout or electrical characteristics updates.

Selection Notes

Select this component when automotive certification is mandatory alongside moderate memory capacity. Compare against the ATSAMC20G16A for lower cost options with reduced memory, or the ATSAMC20G18A if larger storage is required. Consider the TQFP variant ATSAMC20G17A-AUT if through-hole assembly is preferred over surface mount technology.

Part Context

This part belongs to the ATSAMC20 family, designed for cost-sensitive and space-constrained applications. It shares the Cortex-M0+ architecture with other SAM D20 and SAM C20 series devices but offers distinct peripheral sets and packaging options tailored for specific industrial and automotive use cases.

Replacement Considerations

ATSAMC20G17A-AUT provides identical functionality in a TQFP-48 package. ATSAMD20J17A-MUT offers similar specs but in a 64-QFN package with different I/O counts. Verify pin-to-pin compatibility before substituting with these alternatives.
