Overview
The ATSAM4E16EB-ANR is a 32-bit microcontroller based on the ARM Cortex-M4 core, operating at speeds up to 120 MHz. It features 1 MB of in-system programmable Flash memory and 128 KB of SRAM. The device includes an Ethernet MAC with DMA, USB OTG, and multiple communication interfaces including CAN, SPI, and USART. It utilizes a 144-pin LQFP package and supports supply voltages from 1.62 V to 3.6 V.
Feature Summary
- Integrated Ethernet MAC with DMA for high-speed network connectivity
- USB On-The-Go (OTG) controller supporting host and peripheral modes
- CAN bus interface for robust automotive and industrial communication
- Hardware cryptographic engine for secure data processing
Applications
- Industrial automation controllers requiring Ethernet connectivity
- Smart metering systems with secure communication protocols
- Automotive body control modules utilizing CAN bus
- Medical devices requiring secure data handling and USB connectivity
Procurement Notes
Verify the specific suffix 'ANR' against official Microchip documentation to confirm tape-and-reel packaging and temperature range specifications. Ensure compatibility with existing PCB footprints for the 144-LQFP package. Cross-reference pin assignments with the latest datasheet revision to avoid integration errors during procurement and assembly.
Selection Notes
Select this component when both Ethernet and USB connectivity are required within a single MCU. The 1 MB Flash capacity supports complex firmware and large data storage needs. Consider the 120 MHz performance for real-time processing tasks. Verify that the 144-pin package fits the design constraints compared to smaller footprint alternatives in the SAM4E family.
Part Context
This part belongs to the SAM4E series, designed for applications needing high performance and rich connectivity. It integrates an Ethernet MAC and USB OTG, distinguishing it from other SAM4 variants like the SAM4N or SAM4S which lack these specific interfaces. The series targets cost-sensitive yet feature-rich embedded solutions.
Replacement Considerations
Consult official substitution lists for equivalent parts within the SAM4E family. Verify if alternative suffixes denote only packaging changes without affecting electrical characteristics. Do not assume functional equivalence with SAM4N or SAM4S series due to missing Ethernet or USB peripherals.
