• Features extensive connectivity options with multiple serial communication peripherals and USB controllers.
• Provides high-resolution analog-to-digital and digital-to-analog conversion channels for sensor interfacing.

Applications

• Industrial automation control systems
• Audio and video networking equipment
• Human-machine interface (HMI) displays
• Smart metering devices

Procurement Notes

Verify the specific suffix AABT corresponds to the 144-pin LQFP packaging and tape-and-reel shipping configuration. Confirm that the voltage specifications align with the target system design, particularly the core supply requirements. Ensure compatibility with existing development tools such as Atmel-ICE or SAM V71-XULT for programming and debugging purposes.

Selection Notes

Select this component when high processing throughput combined with dedicated audio/video networking capabilities is required. The inclusion of Ethernet AVB distinguishes it from standard SAM V70 variants lacking this peripheral. Consider the pin count and memory size relative to application complexity. Verify thermal management requirements given the operating temperature range and package type.
