ATSAMC20G15A-MNT

Overview

The ATSAMC20G15A-MNT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at a maximum frequency of 48 MHz. It features 32 KB of in-system programmable Flash memory and 4 KB of SRAM. The device supports a supply voltage range of 2.7 V to 5.5 V and includes 38 general-purpose I/O pins. Connectivity options include LIN, I2C, PMBus, SPI, and USART interfaces. It integrates twelve 12-bit ADC channels and five timer/counters. The component is housed in a 48-VQFN package with exposed pad and is qualified to AEC-Q100 standards for automotive applications.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards
• Integrated CAN-FD controller for high-speed communication
• Supports 5V operation within standard 2.7V to 5.5V supply range
• Includes Peripheral Touch Controller (PTC) for capacitive sensing

Applications

• Automotive body control modules
• Industrial motor control systems
• Consumer appliances requiring CAN-FD connectivity
• Battery management systems

Procurement Notes

Verify the specific suffix 'MNT' corresponds to the 48-VQFN package configuration during sourcing. Confirm that the AEC-Q100 qualification status is required for the target application environment. Ensure compatibility with 5V logic levels if interfacing with legacy components. Check for any recent Product Change Notifications regarding assembly or labeling updates from Microchip Technology.

Selection Notes

Select this model when automotive reliability combined with CAN-FD capability is necessary. The 32 KB Flash size suits moderate firmware complexity. The 48-VQFN package offers a compact footprint for space-constrained designs. Consider alternative pin counts if more than 38 I/Os are needed. Verify thermal performance requirements for the chosen operating temperature range.

Part Context

This part belongs to the SAM C20 family, designed for cost-sensitive automotive and industrial markets. It bridges the gap between standard commercial MCUs and higher-end automotive controllers by offering CAN-FD and PTC features. The family emphasizes low power consumption while maintaining robust analog performance and touch sensing capabilities for user interface applications.

Replacement Considerations

Direct substitutes within the same package and pinout include other variants in the ATSAMC20G series with different memory sizes, such as ATSAMC20G16A or ATSAMC20G17A, provided the Flash and RAM capacities meet design requirements. Cross-family replacements like the ATSAMD20 series lack CAN-FD support.
