ATSAM4E16EB-AN 概要
A microcontroller (MCU) is a single integrated circuit that combines a processor core, memory, and programmable peripherals into one chip, sitting at the heart of embedded systems from industrial automation to consumer devices. The SAM4E series belongs to Microchip's (formerly Atmel) 32-bit SAM ARM flash MCU family, positioned above the SAM3 and SAM4N series where high bandwidth, Ethernet, and math-intensive processing are required.
Key differentiating features include the 120 MHz Cortex-M4 core with hardware FPU for single-precision math, a high data bandwidth bus architecture, integrated 10/100 Ethernet MAC, dual CAN 2.0B controllers, a 12-bit ADC, PWM channels, DMA, and safety peripherals such as brown-out detect, power-on reset, and a watchdog timer. This combination suits networked and control-oriented designs that would otherwise require multiple chips.
Technically, the device operates from a 1.2V/3.3V supply scheme (3.3V main, 1.2V core regulation) and is offered in extended temperature, green/RoHS packaging. The Flash-based program memory supports in-system programming, and the external bus interface allows glueless attachment of SRAM, NOR Flash, and LCD modules.
Typical applications include industrial Ethernet gateways, motor control and solar inverter systems, building automation nodes, and embedded networking equipment where CAN, Ethernet, and USB must coexist on one 120 MHz controller.
Design consideration: the LQFP-144 is a fine-pitch (0.5 mm) surface-mount package - plan 4-layer PCB stackups and verify Ethernet PHY magnetics placement early; pinout planning against the 117 I/O budget is essential before routing.

主な用途
ATSAM4E16EB-AN の用途: 6 件s: Industrial Ethernet Gateways, Motor Control and Solar Inverters, Building Automation Nodes, Embedded Networking Equipment, HMI and Display Controllers, Data Acquisition and Test Instrumentation.
Industrial Ethernet Gateways
The ATSAM4E16EB-AN fits industrial Ethernet gateways because it integrates a 10/100 Ethernet MAC, dual CAN 2.0B controllers, and multiple UART/USART ports on a single 120 MHz Cortex-M4 core with FPU. Protocol translation between factory CANbus networks and Ethernet-based supervisory systems is handled without external communication chips, while the 1 MB Flash holds protocol stacks for EtherCAT-adjacent tooling, Modbus TCP, and web servers simultaneously. The DMA controller offloads peripheral transfers so the CPU bandwidth remains available for protocol processing at line rate. With 117 GPIO and the EBI external bus interface, the same chip drives status displays and expansion modules. Operating at 3.3 V with extended temperature grading, it mounts directly on DIN-rail controller boards, and the watchdog plus brown-out reset provide the fault recovery behavior expected in continuously powered industrial installations.
おすすめ
Motor Control and Solar Inverters
The SAM4E16E is positioned by Microchip for motor control and solar inverter applications, and the ATSAM4E16EB-AN's hardware floating point unit executes the single-precision trigonometry behind field-oriented control (FOC) at 120 MHz without software math libraries. The 12-bit ADC samples phase currents synchronized to PWM updates via the peripheral DMA, minimizing CPU jitter in the control loop. Complementary PWM outputs drive three-phase inverter bridges, while the CAN interface links the drive to industrial or vehicle networks for supervisory commands. The 1 MB Flash stores sensorless algorithms, parameter tables, and commissioning diagnostics in one image. Brown-out detection and the watchdog timer ensure safe PWM shutdown during supply anomalies - a critical safety property in high-power conversion stages. The 144-pin LQFP also provides enough I/O to supervise gate-driver fault lines, encoder inputs, and Housekeeping signals on the same die.
おすすめ
Building Automation Nodes
Building automation controllers require networked, low-maintenance, always-on operation, and the ATSAM4E16EB-AN delivers this profile: the Ethernet MAC supports BACnet/IP and web-based management, CAN connectivity interoperates with legacy楼宇 buses, and 117 GPIO lines handle relay banks, sensor inputs, and local keypads on one chip. The 120 MHz Cortex-M4 with FPU executes control loops for HVAC actuators while simultaneously serving the network stack, with DMA keeping ADC and UART streams moving without CPU polling. Extended temperature qualification allows installation in rooftop units and mechanical rooms where ambient temperatures exceed commercial limits. The 1 MB Flash accommodates over-the-air firmware staging for field updates, a common requirement in large building estates. Its green/RoHS LQFP-144 packaging also simplifies compliance documentation for large-volume construction projects requiring environmental declarations from every component supplier.
おすすめ
Embedded Networking Equipment
For compact networking equipment such as managed sensor hubs, serial-to-Ethernet converters, and access-control panels, the ATSAM4E16EB-AN consolidates the needed connectivity - Ethernet, USB device, dual CAN, four-plus UART/USART channels, SPI, and SD card interface - onto one 120 MHz controller. The EBI/EMI external bus interface attaches SRAM or NOR Flash for packet buffering beyond on-chip RAM, a capability few MCUs in this class retain. The USB peripheral supports device-class firmware for configuration tools, while the SD interface logs events to removable media. Hardware DMA on all major peripherals sustains throughput with low CPU load, and the FPU accelerates TLS-adjacent crypto pre-processing. Running at 3.3 V in a 20x20 mm LQFP-144, the design footprint stays compact, and Microchip's active lifecycle status ensures long-term sourcing for products with multi-year service commitments.
おすすめ
HMI and Display Controllers
The EBI/EMI interface of the ATSAM4E16EB-AN attaches LCD modules and graphics memory gluelessly, making it a strong HMI controller: the 120 MHz Cortex-M4 with FPU renders UI elements, touch filtering, and communications concurrently. The 1 MB Flash holds fonts, bitmap assets, and localization tables for multilingual panels, while 117 GPIO lines drive backlight PWM, beeper outputs, and a resistive-touch divider network through its 12-bit ADC. CAN and Ethernet links let the same panel talk to both PLC-level networks and plant IT systems, consolidating what traditionally required two processors. PWM channels provide dimmable backlight control with hardware timebases, keeping brightness stable regardless of CPU load. For industrial panels exposed to temperature extremes, the extended-temp, green LQFP-144 package survives the environment while remaining hand-assemblable with standard hot-bar or reflow equipment used in HMI volume production.
おすすめ
Data Acquisition and Test Instrumentation
Benchtop and rack data-acquisition modules benefit from the ATSAM4E16EB-AN's 12-bit ADC, DMA-driven sampling, USB and Ethernet streaming, and the precision timing available from its timer/counter peripherals at 120 MHz. The FPU performs calibration math - polynomial linearization, RMS computation, FFT windows - in-line without a separate DSP. The EBI interface captures data from external high-speed ADC front-ends or pattern-generator FIFOs through the external bus at memory-like speeds, while 1 MB Flash retains calibration tables and self-test firmware across power cycles. Dual CAN ports connect instruments to vehicle or industrial test networks, useful in HIL test racks. With 117 GPIO available for relay multiplexers, range-switching, and indicator control, a complete 32-channel acquisition channel-select system can be run from this single controller, reducing BOM count and calibration drift points relative to multi-chip designs.

設計ノート
The 144-LQFP uses a 0.5 mm lead pitch - specify solder mask-defined pads with NSMD copper definition and route escape traces at 4-5 mil width to fan out all 144 pins on two inner layers. A 4-layer stackup (signal / GND / power / signal) is recommended for designs using Ethernet, since the RMII/MII interface needs a clean reference plane under the PHY traces. Keep the Ethernet PHY (e.g., KSZ8081) magnetics within 25 mm of the PHY per the PHY vendor layout guide.
The SAM4E operates from a 3.3 V I/O supply with 1.2 V core regulation. Follow the Microchip datasheet power section for VDDCORE/VDDPLL decoupling: place 100 nF ceramics within 2 mm of each supply pin pair and add bulk 10 uF per supply domain. Ensure brown-out threshold configuration matches your supply ramp - disabling BOD during slow-ramping supplies can leave the core in an undefined state after partial power events.
Pin multiplexing is the most common SAM4E design error: many of the 117 I/O pins serve up to four peripheral functions (A/B/C/D per datasheet multiplexing tables). Lock your pin map in Microchip's ATSAM4E datasheet multiplexing appendix BEFORE PCB routing - discovering late that Ethernet RMII and a desired UART conflict forces a respin. Also verify the die revision in use: Microchip recommends Revision B (EB suffix) parts for new prototypes and production per the ATSAM4E16E product page.
