ATSAMD21J17A-AUT

Overview

The ATSAMD21J17A-AUT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, belonging to the SAM D21J Functional Safety (FuSa) series. It features 128KB of in-system programmable Flash memory and 16KB of SRAM. The device operates at a maximum frequency of 48MHz with an internal oscillator. It supports a supply voltage range of 1.62V to 3.6V and includes 52 general-purpose I/Os. Connectivity options include USB, SPI, I2C, UART/USART, LINbus, and I2S. Analog capabilities consist of twenty 12-bit ADC channels and one 10-bit DAC.

Feature Summary

Integrated functional safety features compliant with ISO 26262 standards for automotive applications
Hardware support for direct memory access operations to reduce CPU load
Built-in power management peripherals including brown-out detection and power-on reset

Applications

Automotive infotainment systems requiring functional safety certification
Industrial control units utilizing LINbus communication protocols
Portable devices powered by low-voltage battery sources

Procurement Notes

Verify that the ordering suffix corresponds to the specific tape-and-reel packaging configuration required for automated assembly lines. Confirm the temperature grade matches the operational environment specifications. Ensure the component version aligns with the latest datasheet errata documentation before finalizing procurement orders.

Selection Notes

Select this model when automotive functional safety compliance is mandatory within the SAM D21 family. Choose this variant over non-FuSa versions if diagnostic coverage requirements exceed standard industrial limits. Consider the 64-pin QFN package dimensions against available PCB real estate constraints during the initial layout phase.

Part Context

This component is part of the broader SAM D21 microcontroller portfolio designed for cost-sensitive embedded markets. It shares architectural similarities with other M0+ devices but distinguishes itself through enhanced safety mechanisms. The J-series designation indicates specific pin counts and peripheral configurations tailored for medium-density applications.
