ATSAM4E8CB-CN

Overview

The ATSAM4E8CB-CN is a 32-bit microcontroller based on the ARM Cortex-M4 core, operating at a maximum frequency of 120MHz. It features 512KB of in-system programmable flash memory and 128KB of SRAM. The device includes an Ethernet MAC with an integrated 10/100 Media Access Controller and supports various communication interfaces such as CANbus, SPI, UART/USART, and USB OTG. It operates within a voltage range of 1.62V to 3.6V and is available in a 144-LQFP package.

Feature Summary

• Integrated Ethernet MAC with DMA for high-speed network connectivity
• ARM Cortex-M4 processor with hardware FPU for efficient digital signal processing
• Multiple peripheral interfaces including CAN, USB, and SD/MMC support

Applications

• Industrial automation controllers requiring Ethernet connectivity
• Smart metering systems with data logging capabilities
• Medical equipment with real-time processing requirements

Procurement Notes

Verify the specific suffix CN indicates the extended temperature range and lead-free composition as per Microchip documentation. Confirm the 144-LQFP package dimensions match your PCB footprint design. Ensure compatibility with existing SAM4E series software frameworks before procurement.

Selection Notes

Select this model when Ethernet connectivity is required alongside significant program storage. Compare against ATSAM4E16 variants if larger memory is needed. Consider the LQFP package for easier prototyping compared to BGA options. Verify power supply constraints align with the 1.62V to 3.6V operating range.

Part Context

This component belongs to the SAM4E series of microcontrollers designed for applications requiring robust connectivity and processing power. It shares architectural similarities with other SAM4E devices but offers specific memory and interface configurations tailored for embedded networking tasks.

Replacement Considerations

ATSAM4E8CA-CU: Same specifications in LFBGA-144 package. ATSAM4E16EA-AU: Higher memory capacity in LQFP-144 package.
