ATSAMD21G17A-AUT

Overview

The ATSAMD21G17A-AUT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at a maximum frequency of 48MHz. It features 128KB of in-system programmable Flash memory and 16KB of SRAM. The device supports a supply voltage range of 1.62V to 3.6V and includes an internal oscillator. Connectivity options include I2C, LINbus, SPI, UART/USART, and USB interfaces. It provides 38 general-purpose I/O pins and integrates peripherals such as DMA, PWM, and watchdog timer. The component is housed in a 48-TQFP package with exposed pad.

Feature Summary

Functional Safety (FuSa) compliant design within the SAM D21G series
Integrated full-speed USB device interface for communication
Advanced analog subsystem with multiple 12-bit ADC channels and a 10-bit DAC
Direct Memory Access controller for efficient data transfer management

Applications

Industrial control systems requiring functional safety compliance
USB-enabled embedded devices and peripherals
Low-power consumer electronics applications
General-purpose embedded control tasks

Procurement Notes

Verify the specific suffix 'AUT' against official Microchip documentation to confirm tape-and-reel packaging and temperature grade specifications. Ensure compatibility with existing PCB footprints for the 48-TQFP package. Cross-reference the latest datasheet revision for any errata or pinout clarifications prior to final procurement and design implementation.

Selection Notes

Select this component when Functional Safety (FuSa) certification is required for the application. It is suitable for designs needing integrated USB connectivity alongside standard serial interfaces. Consider the 128KB Flash capacity for complex firmware requirements. Evaluate the 48-TQFP package constraints against available board space and thermal dissipation needs.

Part Context

This part belongs to the SAM D21G family, which emphasizes functional safety capabilities. It shares the Cortex-M0+ architecture with other SAM D21 variants but offers specific memory sizes and package options. The G-series designation typically indicates automotive-grade or enhanced reliability characteristics compared to standard commercial versions.
