ATSAMC20G17A-ANT

Overview

The ATSAMC20G17A-ANT is a 32-bit ARM Cortex-M0+ microcontroller from the Microchip SAM C20 family. It features 128 kB of Flash memory and 16 kB of SRAM, operating at a maximum clock frequency of 48 MHz. The device supports a supply voltage range of 2.7 V to 5.5 V and includes an internal oscillator. It provides 38 I/O pins and integrates multiple communication interfaces including I2C, SPI, USART, and LIN. The component is housed in a 48-pin QFN package and is rated for industrial temperatures between -40°C and +85°C.

Feature Summary

• Integrates an ARM Cortex-M0+ core with DMA support for efficient data processing.
• Includes advanced analog peripherals such as a 12-bit ADC and temperature sensor.
• Supports automotive-grade reliability through AEC-Q100 qualification.

Applications

• Automotive body electronics and gateway applications
• Industrial control systems requiring robust analog input
• Low-power embedded controllers with CAN-FD connectivity

Procurement Notes

Verify the specific suffix 'ANT' corresponds to the 48-QFN package and tape-and-reel packaging configuration. Confirm that the AEC-Q100 qualification status aligns with your automotive or industrial quality requirements. Ensure compatibility with existing design-in tools and debuggers within the Microchip ecosystem before finalizing procurement.

Selection Notes

Select this model when a balance of moderate code storage and high-speed analog conversion is required. The inclusion of CAN-FD makes it suitable for networked environments. Compare against the ATSAMD20 series if automotive certification is not mandatory, or consider the ATSAMC20E series for different pin counts while maintaining similar core performance.

Part Context

This component belongs to the SAM C20 family, designed for cost-sensitive applications requiring 5V tolerance. It shares architectural similarities with the SAM D20 but adds automotive qualification and enhanced analog features like the programmable temperature comparator (PTC).

Replacement Considerations

Direct substitutes include other variants within the ATSAMC20G17A series with different packages, such as ATSAMC20G17A-AUT or ATSAMC20G17A-MUT. Cross-family replacements like the ATSAMD20G17A are functionally similar but lack automotive qualification.
