ATSAMC20G16A-MUT

Overview

The ATSAMC20G16A-MUT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at a maximum frequency of 48 MHz. It features 64 KB of in-system programmable Flash memory and 8 KB of SRAM. The device supports a supply voltage range of 2.7 V to 5.5 V and includes twelve 12-bit analog-to-digital converter channels. Connectivity options include I²C, LINbus, PMBus, SPI, and USART interfaces. It is housed in a 48-VQFN package with an exposed pad and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards
• Integrated support for LINbus communication protocols
• Built-in DMA controller for efficient data transfer management
• Comprehensive analog peripheral set including multiple ADC channels

Applications

• Automotive body control modules
• LIN bus node implementations
• Industrial sensor interfaces
• Consumer appliance controllers

Procurement Notes

Verify the specific suffix 'MUT' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the AEC-Q100 qualification status meets the specific reliability requirements of the target application environment. Ensure compatibility with the 48-VQFN footprint during PCB layout design.

Selection Notes

Select this component when automotive reliability standards are mandatory alongside low-power 32-bit processing capabilities. The inclusion of LINbus hardware support makes it suitable for networked automotive subsystems. Compare against non-automotive variants if cost sensitivity outweighs the need for AEC-Q100 certification in non-critical environments.

Part Context

This part belongs to the Microchip SAM C20 family, designed for cost-sensitive embedded applications requiring robust connectivity. The G-series designation indicates specific pinout and peripheral configurations within the broader SAM C20 portfolio. It complements other members by offering a balance of processing power and integrated communication peripherals in a compact form factor.

Replacement Considerations

ATSAMC20G16A-AUT provides identical functional specifications but utilizes TQFP packaging instead of QFN.
