ATSAMD21J17A-MUT

Overview

The ATSAMD21J17A-MUT 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 52 general-purpose I/Os. Connectivity options include USB, SPI, I2C, UART/USART, LINbus, and I2S interfaces. Integrated peripherals comprise DMA, PWM, WDT, POR, and brown-out detection. Data conversion capabilities consist of twenty 12-bit ADC channels and one 10-bit DAC.

Feature Summary

Functional Safety (FuSa) certification for automotive applications
Integrated USB Device interface with built-in transceiver
Direct Memory Access controller for efficient data transfer
Internal oscillator with calibrated clock output

Applications

Automotive body electronics and lighting control
Industrial motor control and automation
Portable medical devices requiring functional safety
Consumer appliances with USB connectivity

Procurement Notes

Verify the specific suffix 'MUT' corresponds to the 64-QFN package and tape-and-reel orientation as documented in the official Microchip datasheet. Confirm that the Functional Safety qualification status meets the requirements of your target application standard. Ensure compatibility with the SAM D21 family errata document for any known silicon revisions or operational limitations.

Selection Notes

Select this component when automotive functional safety compliance is required alongside low-power ARM Cortex-M0+ performance. It is suitable for designs needing integrated USB connectivity without external transceivers. Consider the 64-QFN package constraints for thermal management and PCB layout. Compare against non-FuSa variants if safety certification is not mandatory for the end product.

Part Context

This part belongs to the SAM D21J series within the Microchip SAM D21 family. It shares architectural similarities with other SAM D21 variants but is distinguished by its Functional Safety qualification. The J17 designation indicates the specific memory configuration of 128KB Flash and 16KB RAM. It complements development tools like the ATATMEL-ICE debugger for programming and debugging.
