Overview
The ATSAMD21G17D-MUT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, belonging to the SAM D21G Functional Safety (FuSa) series. It features 128KB of flash memory and 16KB of RAM, operating at a maximum speed of 48MHz. The device is housed in a 48-QFN (7x7) package with 38 I/O pins. It supports a supply voltage range of 1.62V to 3.63V and operates within a temperature range of -40°C to 85°C. Connectivity includes I2C, LINbus, SPI, UART/USART, and USB interfaces.
Feature Summary
- Integrated functional safety capabilities compliant with automotive standards for reliable operation.
- Advanced analog peripherals including multiple 12-bit ADCs and a 10-bit DAC for signal processing.
- Comprehensive peripheral set supporting DMA, I2S, PWM, and various communication protocols.
Applications
- Automotive infotainment systems requiring functional safety compliance
- Industrial control applications utilizing LINbus and advanced analog inputs
- Portable devices powered by low-voltage battery sources
Procurement Notes
Verify the specific suffix 'MUT' corresponds to the 48-QFN package and tape-and-reel or cut-tape availability as listed by distributors. Confirm that the Functional Safety (FuSa) designation aligns with your project's safety integrity level requirements. Check for any recent Product Change Notifications regarding packaging or assembly sites to ensure supply chain consistency.
Selection Notes
Select this component when both functional safety certification and high-performance analog capabilities are required in a compact form factor. It is suitable for designs needing USB connectivity alongside robust industrial interfaces like LINbus. Compare against non-FuSa variants if safety certification is not mandatory, or against larger packages if more GPIOs are needed.
Part Context
This part is a member of the Microchip SAM D21G family, which extends the standard SAM D21 series with functional safety features. It shares the Cortex-M0+ architecture with other D21 models but distinguishes itself through its specific memory configuration and automotive-grade qualification. It complements higher-memory D21 variants for cost-sensitive safety-critical applications.
Replacement Considerations
ATSAMD21G17A-MUT offers similar specifications but may differ in manufacturing origin or minor revision details. ATSAMD21G17L-MNT provides an extended temperature range up to 105°C. Verify pin compatibility and software library support before substituting with these related FuSa-qualified parts.
