ATSAM4E8EA-AUR

Overview

The ATSAM4E8EA-AUR is a 32-bit microcontroller from the Microchip SAM4E series, featuring an ARM Cortex-M4 core operating at up to 120MHz. It integrates 512KB of flash memory and 128KB of SRAM within a 144-LQFP package. The device supports a supply voltage range of 1.62V to 3.6V and includes peripherals such as USB, CANbus, Ethernet, SPI, I2C, and UART/USART interfaces.

Feature Summary

• Integrates an ARM Cortex-M4 processor with single-precision floating-point unit for high-performance computing
• Includes on-chip NAND flash controller for expanded storage capabilities
• Supports multiple communication protocols including Ethernet MAC and USB OTG

Applications

• Industrial control systems requiring robust connectivity
• Medical devices needing reliable data processing
• Smart metering applications with secure communication needs

Procurement Notes

Verify the specific suffix 'AUR' against official Microchip documentation to confirm tape-and-reel packaging status. Ensure compatibility with required operating temperature ranges and voltage levels before integration into final designs.

Selection Notes

Select this component when dual-core performance is not required but extensive peripheral connectivity like Ethernet and USB is necessary. Compare against the ATSAM4CMP series if cryptographic features or dual-core architecture are needed instead.

Part Context

Part of the SAM4E family designed for cost-effective embedded applications. It shares architectural similarities with other SAM4 variants but focuses on standard connectivity options rather than advanced security cores found in the SAM4CM series.

Replacement Considerations

ATSAM4E8CA-AU: Similar specifications but in LQFP-100 package. ATSAM4E16EA-AU: Higher flash capacity (1MB) in same package.
