ATSAM4E8EA-ANR

Overview

The ATSAM4E8EA-ANR is a Microchip Technology ARM microcontroller featuring an ARM Cortex-M4 core. It provides 512 kB of Flash program memory and 128 kB of SRAM data RAM within a 144-pin LQFP package. The device supports a maximum clock frequency of 120 MHz and operates on a 32-bit data bus width. It includes integrated peripherals such as USB, CAN, Ethernet, and multiple communication interfaces including SPI, I2C, and USART.

Feature Summary

• Integrates an ARM Cortex-M4 processor core for high-performance execution.
• Includes extensive connectivity options with built-in USB, Ethernet, and CAN controllers.
• Features robust analog capabilities with multiple ADC channels and DAC outputs.

Applications

• Industrial automation control systems
• Medical equipment requiring precise signal processing
• Smart metering infrastructure

Procurement Notes

Verify the specific suffix ANR against official Microchip documentation to confirm it denotes the standard tape-and-reel packaging format. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the 144-LQFP footprint matches your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this model when a balance of processing power and peripheral richness is required in a compact form factor. The 120 MHz speed and 512 kB memory suit complex applications. Compare against the ATSAM4E16 series if larger memory capacity is needed, or the ATSAM4S series for cost-sensitive projects with fewer peripherals.

Part Context

This component belongs to the SAM4E family of 32-bit microcontrollers based on the ARM Cortex-M4 architecture. The family is designed for applications demanding high performance and low power consumption. The ATSAM4E8 variant specifically offers mid-range memory configurations suitable for general-purpose embedded control tasks.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified substitutes. Potential alternatives within the same family include the ATSAM4E16 series for increased memory or other packages like the BGA variants if space constraints differ.
