Overview
The ATSAMD21E17D-AUT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, belonging to the SAM D21E Functional Safety (FuSa) series. It features 128KB of in-system programmable Flash memory and 16KB of SRAM. The device operates at a maximum clock frequency of 48MHz with a supply voltage range of 1.62V to 3.63V. It includes an internal oscillator, 26 I/O lines, and supports interfaces such as I2C, LINbus, SPI, USART, and USB. The component is housed in a 32-TQFP package and is rated for an operating temperature range of -40°C to 85°C.
Feature Summary
- Functional Safety (FuSa) certified design compliant with AEC-Q100 standards for automotive reliability
- Integrated full-speed USB device interface for communication capabilities
- Comprehensive peripheral set including DMA, I2S, PWM, and multiple serial communication controllers
Applications
- Automotive infotainment systems requiring functional safety compliance
- Industrial control applications utilizing LINbus connectivity
- Portable devices powered by low-voltage supply rails
Procurement Notes
Verify the specific suffix 'AUT' confirms the Automotive grade qualification and Taping & Reel packaging format. Confirm the manufacturer's RoHS3 status and REACH compliance requirements for your region. Ensure the ESD protection levels meet your circuit design specifications during handling and assembly processes.
Selection Notes
Select this model when automotive functional safety certification is mandatory for the application. Choose this variant over standard SAM D21 parts if AEC-Q100 qualification is required. Consider the 32-TQFP package constraints regarding pin count and thermal dissipation for your PCB layout.
Part Context
This component is part of the Microchip SAM D21E family, specifically tailored for functional safety applications within the broader SAM D21 MCU portfolio. It shares architectural similarities with other SAM D21 variants but distinguishes itself through its automotive-grade qualification and specific memory configuration optimized for safety-critical code execution.
Replacement Considerations
Direct substitutes include other ATSAMD21E17D variants with different packaging options, such as the tray-packaged ATSAMD21E17D-AU. Cross-referencing with non-automotive SAM D21 models requires verification of environmental ratings and safety certifications.
