ATSAMC20J17A-MUT

Overview

The ATSAMC20J17A-MUT is a 32-bit ARM Cortex-M0+ microcontroller from the SAM C20 family, designed for automotive applications with AEC-Q100 qualification. It features 128 kB of Flash memory and 16 kB of SRAM, operating at a maximum clock frequency of 48 MHz. The device supports a supply voltage range of 2.7 V to 5.5 V and includes 52 general-purpose I/Os. Key peripherals include a 12-channel 12-bit ADC, five timers/counters, and interfaces such as LIN, I2C, SPI, and USART. It is housed in a 64-pin VQFN package.

Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards for robust performance in vehicle environments.
• Integrated LIN bus interface support enabling direct communication within local interconnect networks.
• High-resolution analog conversion capabilities via a 12-bit ADC with multiple input channels.
• Flexible peripheral set including DMA, PWM, and watchdog timer for precise system control.

Applications

• Automotive body electronics and comfort systems
• LIN bus node controllers in vehicle networks
• Industrial motor control and automation
• Consumer appliances requiring high-voltage tolerance

Procurement Notes

Verify the specific suffix 'MUT' corresponds to the 64-VFQFN package with exposed pad and tape-and-reel packaging configuration. Confirm that the AEC-Q100 qualification status meets the required automotive grade specifications for the target application environment. Ensure compatibility with the 2.7V to 5.5V supply voltage range during power design.

Selection Notes

Select this component when automotive certification and LIN bus integration are required alongside standard ARM Cortex-M0+ functionality. Compare against the ATSAMD21 series if automotive qualification is not necessary, or against the ATSAMC21 series if higher performance or additional analog features are needed. Consider the 64-pin form factor constraints relative to available PCB space.

Part Context

This part belongs to the Microchip SAM C20 family, which targets cost-sensitive automotive and industrial markets. It shares architectural similarities with the SAM D20 series but adds automotive qualification and enhanced peripheral sets like LIN. The J17 variant specifically denotes the 128 kB Flash and 52 I/O configuration within the QFN package lineup.

Replacement Considerations

ATSAMD20J17A-MUT offers similar specifications but lacks automotive qualification. ATSAMD21J17A-MUT provides enhanced analog features but differs in peripheral availability. ATSAMC21J17A-AUT uses a TQFP package instead of QFN. Verify pinout and software compatibility before substitution.
