Overview
The ATSAMD21J17D-CUT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, part of the SAM D21J Functional Safety series. It features 128KB of flash memory and 16KB of RAM, operating at a maximum speed of 48MHz. The device supports a supply voltage range of 1.62V to 3.63V and includes integrated A/D converters (20x12b) and a D/A converter (1x10b). It offers 52 I/O pins and interfaces including I2C, LINbus, SPI, UART/USART, and USB. Packaged in a 64-UFBGA, it operates within -40°C to 85°C and holds AEC-Q100 qualification.
Feature Summary
- Functional Safety (FuSa) certified for automotive applications
- Integrated analog peripherals with multiple ADC channels and DAC
- Comprehensive connectivity suite including USB and LINbus support
Applications
- Automotive body electronics systems
- Industrial control modules requiring functional safety compliance
- Consumer devices with USB connectivity requirements
Procurement Notes
Verify the specific suffix indicates tape-and-reel packaging distinct from tray options. Confirm the extended temperature grade (-40°C to 85°C) matches application needs compared to industrial variants. Ensure AEC-Q100 certification status is current per latest datasheet revisions before finalizing component selection for production.
Selection Notes
Select this variant when automotive functional safety certification is mandatory alongside compact UFBGA packaging. Compare against ATSAMD21J17D-CU if tray packaging is preferred or different thermal profiles are required. Consider ATSAMD21J17D-MF for QFN package alternatives while maintaining identical electrical specifications and memory configurations.
Part Context
This component belongs to the Microchip SAM D21 family, specifically designed for functional safety applications. It shares the core architecture with other SAM D21J variants but differs in package type and temperature rating. The CUT suffix denotes the reel packaging format suitable for automated surface-mount assembly processes.
Replacement Considerations
ATSAMD21J17D-CU serves as a direct pin-compatible alternative with identical electrical characteristics but utilizes tray packaging instead of tape-and-reel.
