ATSAMD21G17D-MFT

Overview

The ATSAMD21G17D-MFT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, belonging to the SAM D21J series with Functional Safety (FuSa) certification. It features 128KB of Flash memory and 16KB of RAM, operating at a maximum frequency of 48MHz. The device supports a supply voltage range of 1.62V to 3.63V and includes an internal oscillator. It offers 52 I/O pins and integrates peripherals such as DMA, I2S, PWM, and WDT. Connectivity options include I2C, LINbus, SPI, UART/USART, and USB. The component is housed in a 64-QFN (9x9) package and is rated for an industrial temperature range of -40°C to 125°C.

Feature Summary

• Functional Safety (FuSa) certified for automotive applications
• Integrated AEC-Q100 qualification for reliability
• Advanced analog capabilities with multiple ADC channels

Applications

• Automotive functional safety systems
• Industrial control units requiring high reliability
• Consumer electronics with strict safety standards

Procurement Notes

Verify the specific suffix 'MFT' corresponds to the tape and reel packaging format when ordering. Confirm that the FuSa designation aligns with your system's safety integrity level requirements. Ensure the 64-QFN footprint matches your PCB design guidelines. Check for any recent Product Change Notifications regarding packaging or labeling updates from Microchip Technology before finalizing procurement.

Selection Notes

Select this model if your application requires Functional Safety certification alongside standard MCU features. Compare pin counts and peripheral sets against other SAM D21 variants like the G-series if fewer I/Os are sufficient. Consider the extended temperature range (-40°C to 125°C) for harsh environments. Verify compatibility with existing development tools and debuggers for the Cortex-M0+ architecture.

Part Context

This part is part of the SAM D21 family, designed for low-power, high-performance applications. It shares the core architecture with other SAM D21 devices but differs in memory size, I/O count, and package type. The FuSa variant specifically targets markets requiring compliance with automotive safety standards, distinguishing it from standard commercial-grade counterparts in the same family.

Replacement Considerations

Direct substitutes within the SAM D21 family include ATSAMD21J17D-MFT, which shares identical specifications and pinout. Other variants may require schematic and firmware modifications due to differences in I/O count or memory capacity.
