ATSAM4E8CB-AN

Overview

The ATSAM4E8CB-AN is a 32-bit microcontroller from the Microchip SAM4E series, built on an ARM Cortex-M4 core. It features 512KB of in-system programmable Flash memory and 128KB of SRAM. The device operates at a maximum clock frequency of 120MHz with a supply voltage range of 1.62V to 3.6V. It includes a comprehensive peripheral set such as USB, Ethernet, CAN, and multiple communication interfaces. The component is housed in a 100-pin LQFP package and supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-performance 32-bit ARM Cortex-M4 processor with a floating-point unit for efficient signal processing.
• Includes dedicated hardware cryptographic accelerators for secure data handling and authentication.
• Features an integrated Ethernet MAC with DMA support for robust network connectivity applications.

Applications

• Industrial control systems requiring deterministic real-time performance
• Smart metering infrastructure with security requirements
• Medical devices needing reliable embedded processing

Procurement Notes

Verify the specific suffix 'AN' against official datasheets to confirm extended temperature ratings and material compliance status. Ensure compatibility with existing PCB footprints for the 100-LQFP package. Cross-reference pin assignments with current revision errata sheets before finalizing design implementation.

Selection Notes

Select this model when both Ethernet connectivity and cryptographic security are required within a single MCU. Compare RAM and Flash capacities against application needs relative to other SAM4E variants. Consider the 120MHz speed limit and available GPIO count for system architecture planning.

Part Context

This component belongs to the SAM4E family, which targets cost-sensitive applications demanding Ethernet and security features. It shares architectural similarities with the SAM4S series but adds native Ethernet MAC capabilities. The part serves as a bridge between standard industrial MCUs and more complex networking processors.

Replacement Considerations

ATSAM4E8CA-AU: Same specifications in LQFP-100 package. ATSAM4E8CB-CU: Same specifications in LFBGA-100 package. Verify package dimensions and thermal characteristics when substituting.
