ATSAME70J19A-AN

Overview

The ATSAME70J19A-AN 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, and multiple communication interfaces including Ethernet, CANbus, and USB.

Feature Summary

• Integrates an ARM Cortex-M7 processor with FPU for high-performance computing
• Includes dedicated Ethernet MAC with DMA for network connectivity
• Features multiple analog-to-digital converters and digital-to-analog converters
• Supports various serial communication protocols including SPI, I2C, and UART

Applications

• Industrial automation controllers
• Medical equipment control systems
• Smart metering applications
• Human-machine interface displays

Procurement Notes

Verify the specific suffix AN indicates the 64-LQFP package variant. Confirm RoHS compliance status through official Microchip documentation. Check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this model when a balance of processing power and moderate I/O count is required. Compare against the ATSAMV70 series if higher clock speeds are needed. Ensure the 64-pin form factor fits the target PCB layout constraints compared to larger packages in the same family.

Part Context

This component belongs to the SAM E70 family designed for cost-sensitive embedded applications requiring robust connectivity. It shares architectural similarities with the S70 and V71 series but offers distinct memory configurations and peripheral sets tailored for general-purpose industrial use cases.

Replacement Considerations

ATSAME70J19A-ANT serves as a tape-and-reel alternative with identical electrical specifications. Verify package compatibility when substituting between tray and reel variants.
