ATSAMC20J17A-ANT

Overview

The ATSAMC20J17A-ANT is an ARM-based microcontroller from the Microchip ATSAMC20 series, featuring an ARM Cortex-M0+ core. It integrates 128 kB of program memory and 16 kB of data RAM within a 64-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 a 12-bit ADC with 12 channels and provides 52 general-purpose I/O pins. The component is qualified under AEC-Q100 standards for automotive applications and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for reliable operation in demanding environments.
• Integrated 12-bit analog-to-digital converter supporting multiple input channels for precise signal acquisition.
• Supports multiple communication interfaces including LIN, I2C, SPI, and USART for versatile system connectivity.

Applications

• Automotive body electronics and control modules
• Industrial sensor nodes and monitoring systems
• General embedded control applications requiring automotive reliability

Procurement Notes

Verify the specific suffix ANT indicates the 64TQFP package and 85°C temperature grade during procurement. Confirm that the ordering information matches the required reel or cut tape format as specified by the manufacturer. Ensure compatibility with existing design constraints regarding pinout and thermal performance before finalizing purchase orders.

Selection Notes

Select this model when automotive certification (AEC-Q100) is mandatory alongside the specific memory configuration of 128 kB Flash and 16 kB SRAM. It is suitable for designs requiring a 64-pin surface-mount package with extensive I/O capabilities. Consider alternative packages like MUT or UUT if board space constraints differ, but maintain the J17 variant for identical core specifications.

Part Context

This component belongs to the ATSAMC20 family, which targets cost-sensitive embedded applications requiring robust performance. The J-series variants typically offer higher pin counts and memory capacities compared to G or E series counterparts. The ATSAMC20J17A-ANT specifically bridges the gap between standard industrial MCUs and automotive-grade requirements without necessitating a complete architecture change.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify cross-references with other ATSAMC20J17 variants differing only in package type (e.g., ATSAMC20J17A-MUT) if pin compatibility allows.
