ATSAMD21J17D-MUT

Overview

The ATSAMD21J17D-MUT 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 flash memory and 16KB of RAM, operating at a maximum speed of 48MHz with an internal oscillator. The device supports a supply voltage range of 1.62V to 3.63V and includes 52 I/O pins. Connectivity options include I2C, LINbus, SPI, UART/USART, and USB. It integrates 20-channel 12-bit ADCs and one 10-bit DAC. Packaged in a 64-QFN (9x9), it operates between -40°C and 85°C.

Feature Summary

Functional Safety (FuSa) certification for automotive applications
Integrated high-speed full-speed USB interface
Advanced analog peripherals including multiple 12-bit ADCs and a 10-bit DAC
Comprehensive peripheral set including DMA, I2S, PWM, and watchdog timer

Applications

Automotive infotainment systems requiring functional safety compliance
Industrial control units utilizing LINbus communication
Portable devices powered by low-voltage battery sources
Data acquisition systems leveraging multiple analog input channels

Procurement Notes

Verify the specific suffix 'MUT' corresponds to the tape and reel packaging format intended for automated assembly. Confirm that the operational temperature range of -40°C to 85°C meets the environmental requirements of the target application. Ensure design compatibility with the 64-QFN package dimensions and thermal dissipation needs. Cross-reference the latest datasheet revision for any errata or clarification updates relevant to the SAM D21 family.

Selection Notes

Select this component when functional safety standards are mandatory for the project. Choose this model over non-FuSa variants if automotive qualification is required. Consider this part for designs needing integrated USB capabilities without external transceivers. Evaluate the 128KB flash capacity against firmware size requirements to ensure sufficient storage for complex safety logic.

Part Context

This MCU is part of the SAM D21J family, which focuses on functional safety for automotive environments. It shares the Cortex-M0+ architecture with other SAM D21 variants but distinguishes itself through FuSa qualifications and specific pinout configurations. The device complements Microchip's portfolio of low-power, high-performance 32-bit controllers designed for demanding industrial and automotive sectors.
