ATSAMC20N17A-ANT

Overview

The ATSAMC20N17A-ANT is an ARM microcontroller from the Microchip SAM C20 family, featuring an ARM Cortex-M0+ core. It provides 128 kB of program memory and 16 kB of SRAM data RAM within a 48-pin TQFP package. The device supports a maximum clock frequency of 48 MHz and operates on a supply voltage range of 2.7 V to 5.5 V. It includes 38 I/O lines, a 12-bit ADC with 14 channels, and a 10-bit DAC. The component is qualified under AEC-Q100 standards for automotive applications and functions reliably across a temperature range of -40°C to +105°C.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for extended industrial reliability
• Integrated analog peripherals including a 12-bit ADC and 10-bit DAC for signal processing
• Supports multiple communication interfaces such as SPI, USART, I2C, LIN, and PMBus
• Operates within a wide voltage range of 2.7 V to 5.5 V for flexible power integration

Applications

• Automotive electronic control units requiring AEC-Q100 compliance
• Industrial sensor nodes utilizing high-resolution analog-to-digital conversion
• Battery-powered devices leveraging low-power ARM Cortex-M0+ architecture
• Communication gateways supporting LIN and PMBus protocols

Procurement Notes

Verify the specific suffix 'ANT' corresponds to the required tape-and-reel packaging configuration. Confirm that the AEC-Q100 qualification aligns with your target automotive or industrial application requirements. Ensure the 48 MHz clock speed and 128 kB memory capacity meet the firmware size and performance constraints of the design. Check compatibility with the 2.7 V to 5.5 V operating voltage range against the system power rails.

Selection Notes

Select this component when automotive reliability and wide voltage operation are critical. The 128 kB flash and 16 kB RAM provide sufficient resources for complex control algorithms. The inclusion of LIN and PMBus interfaces makes it suitable for networked systems. Compare against the ATSAMC21 series if higher performance or different pin counts are needed, while noting the specific memory and interface differences between the C20 and C21 families.

Part Context

This part belongs to the Microchip SAM C20 family of 32-bit ARM Cortex-M0+ microcontrollers. The family is designed for cost-sensitive and power-efficient applications. The 'N' designation typically indicates a specific pin count and peripheral set within the series. The ATSAMC20N17A variant offers a balanced mix of memory and connectivity for embedded control tasks.

Replacement Considerations

Direct substitutes within the same package and specification include other variants in the ATSAMC20NxxA series, such as ATSAMC20N18A, provided memory sizes match requirements. Cross-family replacements like the ATSAMC21G17A-ANT offer similar functionality but may differ in specific peripheral configurations or package availability.
