Overview
The ATSAMD21E17D-MF is a 32-bit ARM Cortex-M0+ microcontroller from the SAM D21E series, designed for functional safety applications. It features 128 kB of Flash program memory and 16 kB of SRAM data memory. The device operates with a maximum clock frequency of 48 MHz and supports an input/output count of 26 I/O lines. It includes a 12-bit ADC and a 10-bit DAC. The unit is housed in a 64-QFN (9x9) package and is qualified to AEC-Q100 standards for automotive use, operating within a temperature range of -40°C to +125°C.
Feature Summary
- AEC-Q100 qualified for automotive reliability requirements
- Functional Safety (FuSa) design compliance
- Integrated USB interface capability
- Supports multiple communication protocols including SPI, I2C, USART, and LIN
Applications
- Automotive electronic control units
- Industrial automation controllers
- Consumer electronics requiring functional safety
- Battery management systems
Procurement Notes
Verify the specific suffix 'MF' corresponds to the 64-QFN package and industrial/automotive temperature grade during sourcing. Confirm RoHS3 compliance status as required by project specifications. Ensure the supplier provides valid traceability documentation for AEC-Q100 qualified components. Cross-reference the datasheet revision date to ensure compatibility with current errata sheets before finalizing procurement orders.
Selection Notes
Select this component when a small form factor with automotive qualification is required. The 64-pin QFN package offers a compact footprint suitable for space-constrained designs. The inclusion of a USB peripheral distinguishes it from non-USB variants in the same memory class. Consider the 125°C junction temperature rating for high-thermal environments where standard industrial parts may fail.
Part Context
This part belongs to the Microchip SAM D21E family, which focuses on functional safety for embedded applications. Unlike the standard SAM D21 series, the E-series variants undergo rigorous testing to meet automotive reliability standards. The device shares the core architecture with other SAM D21 models but differs in package options and qualification levels.
Replacement Considerations
ATSAMD21E17D-MUT: Same core and memory but in VQFN-32 package with limited I/O. ATSAMD21J17D-MFT: Higher pin count (64 pins) with more I/O options in a similar QFN package.
