Overview
The ATSAMC20J17A-MNT is a 32-bit microcontroller unit based on the ARM Cortex-M0+ core, manufactured by Microchip Technology. 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 a supply voltage range from 2.7 V to 5.5 V. It includes an integrated 12-bit ADC with 12 channels and five timer/counters. The component is housed in a 64-pin VQFN package and is qualified under AEC-Q100 standards for automotive applications.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q100 standards for reliability in demanding environments.
- Integrated analog-to-digital conversion capabilities with 12-bit resolution across multiple input channels.
- Supports various serial communication interfaces including LIN, I2C, SPI, and USART for system connectivity.
Applications
- Automotive body electronics and control modules
- Industrial sensor nodes requiring LIN bus communication
- Consumer devices operating within extended temperature ranges
Procurement Notes
Verify the specific suffix MNT indicates tape and reel packaging when ordering. Confirm that the AEC-Q100 qualification meets the specific reliability requirements of the target application. Ensure compatibility with the 2.7V to 5.5V supply voltage range during power design. Check for any recent product change notices regarding manufacturing sites or materials.
Selection Notes
Select this model when automotive certification is mandatory alongside a Cortex-M0+ architecture. Compare against ATSAMD20 series if automotive qualification is not required but pin compatibility is needed. Consider the ATSAMC21 series if DMA support or higher performance peripherals are necessary for the application workload.
Part Context
This component belongs to the SAM C20 family of microcontrollers designed for cost-sensitive automotive and industrial markets. It shares architectural similarities with the SAM D20 series but adds automotive qualification and specific interface support like LIN. The J17 designation typically indicates the specific memory configuration and package type within the family.
Replacement Considerations
ATSAMD20J17A-MNT offers similar electrical specifications but lacks automotive qualification. ATSAMC20J18A-MNT provides increased memory capacity while maintaining the same package and core architecture.
