ATSAM4E16EA-CU

Overview

The ATSAM4E16EA-CU is a 32-bit microcontroller from the Microchip SAM4E series, featuring an ARM Cortex-M4 core with FPU. It integrates 1 MB of in-system programmable Flash memory and 128 KB of SRAM. The device operates at a maximum clock frequency of 120 MHz and supports a supply voltage range of 1.08 V to 1.32 V. It includes 16-channel 16-bit ADCs, multiple communication interfaces such as USB, CAN, UART, and USART, and is housed in a 144-pin LFBGA package suitable for industrial temperature ranges.

Feature Summary

• Integrates an ARM Cortex-M4 processor core with hardware floating-point unit for efficient signal processing.
• Provides extensive connectivity through integrated Ethernet MAC, USB OTG, CAN bus, and multiple serial interfaces.
• Features high-resolution analog-to-digital conversion capabilities with 16-bit resolution across multiple channels.
• Supports external memory interface for expansion of program or data storage beyond internal limits.

Applications

• Industrial automation controllers requiring robust communication protocols
• Medical devices needing precise analog signal acquisition
• Smart metering systems with secure data transmission
• Consumer electronics utilizing USB connectivity

Procurement Notes

Verify the specific suffix 'CU' indicates the LFBGA-144 package and industrial temperature grade. Confirm RoHS compliance status via the official datasheet. Ensure design-in compatibility with 1.08V to 1.32V power domains. Check for moisture sensitivity level requirements during assembly. Validate pinout against target PCB layout constraints.

Selection Notes

Select this component when 1 MB Flash and 128 KB RAM are required alongside 120 MHz performance. Choose over smaller variants if extensive I/O count and advanced peripherals like Ethernet are necessary. Consider the LFBGA package for space-constrained designs requiring thermal efficiency. Compare with ATSAM4E16EA-AU if QFP packaging is preferred instead of BGA.

Part Context

This part belongs to the SAM4E family of ARM-based microcontrollers designed for cost-sensitive applications. It bridges the gap between high-performance Cortex-M4 devices and simpler Cortex-M0 solutions. The series emphasizes peripheral integration to reduce external component count. It targets markets demanding reliable operation in industrial environments.

Replacement Considerations

ATSAM4E16EA-AU offers identical electrical specifications but utilizes a 144-LQFP package instead of LFBGA. Verify footprint compatibility before substitution. No other direct pin-to-pin replacements exist within the same memory configuration without package changes.
