ATSAME70J19A-ANT

Overview

The ATSAME70J19A-ANT is a 32-bit microcontroller from the SAM E70 series, featuring an ARM Cortex-M7 core operating at 300MHz. It integrates 512KB of Flash memory and 256KB of SRAM within a 64-LQFP package. The device supports a supply voltage range of 1.62V to 3.6V and includes peripherals such as DMA, I2S, PWM, and multiple communication interfaces including Ethernet, CANbus, SPI, and USB.

Feature Summary

• High-performance ARM Cortex-M7 processor with DSP instructions
• Integrated Ethernet MAC and USB OTG controller
• Flexible memory architecture with DMA support
• Comprehensive analog interface suite

Applications

• Industrial automation controllers
• Medical equipment processing units
• Smart energy metering systems
• Human-machine interface displays

Procurement Notes

Verify the specific suffix 'ANT' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the 64-LQFP footprint matches the target PCB design constraints. Ensure compatibility with the 1.62V to 3.6V power domain requirements for the specific application environment.

Selection Notes

Select this component when high computational throughput is required alongside robust connectivity options like Ethernet and USB. The 512KB Flash capacity suits complex firmware implementations. Consider the 64-pin form factor for space-constrained designs requiring significant I/O density without moving to larger packages.

Part Context

This part belongs to the SAM E70 family, designed for applications demanding high performance and rich connectivity. It shares architectural similarities with the SAM S70 but distinguishes itself through integrated Ethernet capabilities. The family targets industrial and medical markets requiring reliable real-time processing.

Replacement Considerations

ATSAME70J19A-AN serves as the tray-packaged equivalent. ATSAMS70J19A-ANT offers similar specifications but lacks the Ethernet peripheral found in the E70 variant.
