ATSAMC20J17A-UUT

Overview

The ATSAMC20J17A-UUT is an automotive-grade ARM microcontroller from the SAM C20 family, featuring an ARM Cortex-M0+ core. It integrates 128 kB of Flash program memory and 16 kB of SRAM data memory within a 56-ball WLCSP package. The device supports a maximum clock frequency of 48 MHz and operates on a supply voltage range of 2.7 V to 5.5 V. It includes a 12-bit ADC with 12 channels and provides 52 general-purpose I/O pins. The component meets AEC-Q100 qualification standards for operation between -40°C and +85°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
• Integrated 12-bit analog-to-digital converter supporting multiple channel inputs for sensor interfacing.
• Supports LIN bus communication protocols alongside standard serial interfaces for network connectivity.

Applications

• Automotive body control modules requiring robust MCU performance.
• LIN bus node implementations in vehicle networking architectures.
• Industrial applications operating within extended temperature ranges.

Procurement Notes

Verify the specific suffix UUT indicates the WLCSP-56 packaging configuration distinct from other variants. Confirm AEC-Q100 automotive qualification status matches project requirements. Check current manufacturing availability as this may be a special order item. Ensure ESD handling procedures are followed due to moisture sensitivity classification.

Selection Notes

Select this model when automotive certification is mandatory for the SAM C20 platform. Choose the WLCSP package for compact board space constraints compared to TQFP options. Ensure system power design accommodates the 2.7V to 5.5V input range. Verify peripheral count meets interface needs for LIN and SPI/USART connections.

Part Context

This component belongs to the Microchip SAM C20 series, designed for cost-sensitive embedded applications. The series utilizes the efficient ARM Cortex-M0+ architecture. The ATSAMC20J17A variant specifically offers higher memory capacity than smaller pin-count siblings. The UUT suffix denotes the wafer-level chip scale package format.

Replacement Considerations

ATSAMC20J17A-AUT serves as a direct functional alternative with identical specifications but utilizes a TQFP-64 package instead of WLCSP. Both parts share the same core, memory, and automotive qualification status.
