ATSAM4E16EA-CU - 120MHz Cortex-M4 MCU | Microchip
Teilenummer: ATSAM4E16EA-CU ✓ AktivATSAM4E16EA-CU Übersicht
A microcontroller is a complete programmable control system built around a central processing unit, memory, and peripheral interfaces. The Cortex-M4 processor provides a 32-bit instruction set and hardware floating-point capability, while the 120 MHz operating frequency supports responsive control loops and higher-throughput data processing than typical 8- or 16-bit embedded controllers.
The ATSAM4E16EA-CU provides 1 MB of flash organized as 1M x 8 and is supplied in a 144-LFBGA package. Its green package designation identifies an industrial-temperature component variant, and the package suffix indicates the specified temperature range, qualification status, and packing configuration. The Microchip ATSAM4E16E product page identifies the device as an ARM Cortex-M4 processor-based MCU with a floating-point unit and a high-data-bandwidth architecture.
This MCU is suited to gateways and industrial network controllers, embedded Ethernet equipment, human-machine interfaces, data acquisition systems, and connected industrial automation. The combination of 120 MHz processing performance and 1 MB of program flash provides useful headroom for protocol stacks, control software, and moderate local data buffering.
The 144-ball LFBGA package supports dense board layouts but requires careful escape routing and a stable multilayer PCB stackup. Because ATSAM4E16EA-CU is the -CU orderable configuration, engineers should confirm the exact pin assignment, exposed-pad requirements, and package dimensions in the manufacturer datasheet before releasing artwork.
This page consolidates core device attributes, verified source links, family-level drop-in options, and practical implementation guidance. It also highlights that Microchip recommends Revision B devices for new prototypes and production designs, making revision selection a necessary engineering check for long-lived products.

Industrial Ethernet Gateway Controller
The ATSAM4E16EA-CU fits an industrial Ethernet gateway where a 120 MHz Cortex-M4 core supplies the processing throughput for protocol handling and local control tasks. Its 1 MB internal flash provides substantially more program space than small 8- or 16-bit network controllers, allowing Ethernet stacks, management interfaces, and application firmware to coexist. The hardware floating-point unit can accelerate filtering and control calculations. Place the MCU close to the Ethernet PHY and magnetics sections, route clocks and differential interfaces according to the manufacturer layout guidance, and confirm that the selected SAM4E configuration provides the required Ethernet MAC and media-access interfaces.
Empfohlen
Industrial Automation Terminal
A human-machine interface terminal can use the ATSAM4E16EA-CU to manage display updates, key input, status logging, and communications with a higher-level controller. At 120 MHz, the Cortex-M4 processor provides ample headroom for graphical user-interface logic alongside protocol tasks, while 1 MB of flash accommodates a larger embedded application. The 144-LFBGA footprint supports dense boards with high I/O availability. Use a multilayer PCB with dedicated ground planes, keep LCD and touch-controller interfaces away from switching power nodes, and follow the datasheet decoupling and clock-layout recommendations.
Empfohlen
Data Acquisition and Control Module
The ATSAM4E16EA-CU suits data-acquisition modules that combine sensor conditioning, digital control, and buffered local processing. The 120 MHz 32-bit Cortex-M4 core can execute filtering and control algorithms concurrently with communications, and its hardware floating-point unit improves throughput for numeric routines. The 1 MB program memory is suitable for substantial drivers, calibration tables, and control firmware. Verify the exact analog peripheral set and operating voltage in the selected device configuration, isolate analog inputs from digital switching paths, and use continuous reference planes beneath the fine-pitch BGA footprint.
Empfohlen
Connected Equipment Controller
For connected industrial or building equipment, the ATSAM4E16EA-CU can run the main control loop, communication protocol, diagnostics, and data logging in one microcontroller. The 120 MHz Cortex-M4 architecture provides the processing headroom for multi-task firmware, and the 1 MB flash capacity supports richer application code than entry-level MCUs. The 144-ball package exposes the pins needed for multiple serial, digital, and control interfaces. Plan power domains for orderly startup, provide local bulk and high-frequency decoupling, and verify every peripheral assignment against the selected package pinout before layout release.
Empfohlen
Motor and Motion Control
The ATSAM4E16EA-CU can serve as the supervisory controller in a multi-axis motion system, coordinating position feedback, communications, and fault handling. Its 120 MHz 32-bit execution speed supports responsive supervisory tasks, while hardware floating-point capability is useful in motion-control calculations. The 1 MB of flash allows control firmware, field-bus stacks, and diagnostic routines to run from a single device. Separate analog and power sections of the layout, provide adequate return paths for motor-drive switching nodes, and use the datasheet pin descriptions to assign timers and communication interfaces correctly.
Empfohlen
Secure Network Edge Device
The ATSAM4E16EA-CU is suitable for network-edge appliances that must maintain real-time control while handling protocol processing and secure communication tasks. Its 120 MHz Cortex-M4 core and 1 MB of internal flash provide a practical balance of performance and program capacity for embedded gateways, concentrators, and industrial communications hubs. The 144-LFBGA package allows a compact implementation with substantial I/O access. Route high-speed signals over continuous reference planes, keep sensitive clock and reset traces short, and follow the manufacturer's guidance for external memory, power sequencing, and decoupling.

Wichtigste Unterscheidungsmerkmale
- Substantially larger program memory than the listed SAM4SD comparison (vs. ATSAM4SD32BA-MU)
- 120 MHz Cortex-M4 processing performance (vs. ATSAM4SD32BA-MU)
- Same-family configuration alternative with identical core and memory (vs. ATSAM4E16EA-AU)
- Documented recommendation for new-design revision selection (vs. ATSAM4SD32BA-MU)
Designhinweise
Use the manufacturer 144-LFBGA land pattern for a 10 x 10 mm package rather than a generic BGA footprint. Confirm pad dimensions, solder-mask definition, and assembly requirements with the board house. A multilayer board with continuous ground and power planes is strongly preferred because the 144-ball component needs dense via fan-out and short return paths.
Follow the datasheet decoupling and power-sequence requirements exactly, including the placement of bulk and high-frequency capacitors at their designated pins. Keep the 120 MHz clock and sensitive analog or communication traces away from inductors and switching nodes. Validate the regulator startup behavior and any load-slew requirement in the final system rather than treating the MCU rail as an unrestricted digital supply.
Assign every BGA ball from the official package drawing, including supply, ground, and reserved positions. Preserve the package's standard pin-1 orientation, verify the assembled board against the pick-and-place file, and avoid substituting a pin-compatible but electrically different SAM4SD configuration without a complete peripheral and firmware review.
Do not assume that an identical package suffix is the only qualification issue. Check the device revision, temperature range, qualification statement, packing code, and software-device identifier before releasing a purchase order. Microchip's recommendation to consider Revision B for new designs makes this review particularly important for long-lived production programs.
Compliance-Informationen
The green industrial package designation and general Microchip documentation do not by themselves establish every compliance status. Confirm RoHS, REACH, AEC-Q100, lead-free, halogen-free, and conflict-minerals declarations for the exact orderable MPN and current revision.
