MPN： ATSAM4E16EA-AN ✓ 啟用中ATSAM4E16EA-AN 概覽
A microcontroller is a programmable semiconductor that integrates a processor core, memory, peripherals, and interface logic on one integrated circuit. The ARM Cortex-M4 processor core is designed for efficient embedded execution and supports floating-point instructions that accelerate calculations commonly found in control loops, signal processing, and data transformation. Within the product hierarchy, this ATSAM4E16EA-AN is a microcontroller, embedded processor, semiconductor, and programmable control device.
Three headline attributes define the device: a maximum processor frequency of 120 MHz, 1 MB of Flash organized as 1M by 8 bits, and a 144-LQFP surface-mount package. The processor architecture provides the compute capacity needed for responsive real-time control, while the 1 MB Flash allocation supports embedded firmware, configuration data, and application code. The 20 mm by 20 mm LQFP package provides exposed leads for PCB assembly and inspection.
Microchip describes the SAM4E16E family as featuring a floating-point unit and a high-data-bandwidth architecture. These characteristics make the processor core useful in designs that combine supervisory control with math-intensive routines. The 32-bit Cortex-M4 architecture provides a modern embedded baseline, while the 1 MB Flash capacity reduces the need to rely on external program storage for moderate firmware images.
Typical applications include industrial automation controllers, Ethernet-connected equipment, operator panels, data-acquisition systems, medical-instrument control boards, and embedded gateway products. In each case, the 120 MHz Cortex-M4 core supplies real-time processing capability, the Flash memory holds application firmware, and the 144-LQFP package supports conventional surface-mount assembly. Automotive or safety-critical use requires project-specific qualification review before deployment.
Design should begin with the manufacturer's pin description table and electrical characteristics because package dimensions alone do not define the board interface. Preserve the recommended decoupling and external-component layout, confirm signal levels and peripheral assignments against the device documentation, and verify PCB thermal performance at the intended ambient temperature. Revision planning is also important because Microchip recommends Revision B for new prototype and production designs.
This page organizes the verified product identity, package information, sourcing answers, design considerations, and compatibility boundaries for ATSAM4E16EA-AN. It also distinguishes confirmed electrical and packaging facts from characteristics that require engineering review before schematic release, PCB layout, firmware migration, or production qualification.

典型應用
ATSAM4E16EA-AN 適用於 6 應用s: Industrial Automation Controllers, Communications Gateways, Human-Machine Interfaces, Data-Acquisition Equipment, Medical and Laboratory Instruments, IoT and Edge Sensor Nodes.
Industrial Automation Controllers
ATSAM4E16EA-AN fits industrial automation controllers that combine real-time supervisory functions with moderate embedded application code. Its 120 MHz 32-bit ARM Cortex-M4 processor provides useful throughput for control sequencing and communications handling, while the floating-point unit supports calculations such as proportional control, filtering, and scaling. The confirmed 1 MB Flash capacity accommodates firmware, configuration tables, and operating parameters without requiring external program memory. In a controller, the device can coordinate machine-state logic, process interfaces, and diagnostics while maintaining deterministic control behavior. The 144-LQFP package is practical for conventional industrial board layouts, but the final design must verify supply rails, peripheral assignments, isolation boundaries, temperature requirements, and EMC performance against the manufacturer documentation.

Communications Gateways
ATSAM4E16EA-AN is suitable for protocol-conversion and communications gateway products that need more compute capacity than a basic control MCU. The 120 MHz Cortex-M4 core can process framing, buffering, routing, and supervisory logic, while the floating-point unit can assist with signal-level calculations and telemetry transformations. Its 1 MB internal Flash provides space for a substantial firmware image and configuration database. In a gateway, the microcontroller can bridge a local sensor or machine bus to an upper-level Ethernet or serial interface, subject to confirmation of the exact peripheral resources and pin assignments. The 144-LQFP package also exposes a broad set of I/O for status indicators, communication transceivers, and service interfaces. Validate protocol timing, transceiver requirements, thermal margins, and firmware resource allocation before production release.
推薦
Human-Machine Interfaces
ATSAM4E16EA-AN can serve as the central controller in a human-machine interface panel that must manage display updates, keypad input, indicators, and communications. The 120 MHz Cortex-M4 architecture provides responsive task scheduling for graphical or parameter-oriented interfaces, and the floating-point unit assists with display scaling and real-time data conversion. A 1 MB Flash allocation is useful for retaining interface firmware, fonts, configuration data, and communication parameters within the microcontroller. The 144-LQFP package allows connection to display controllers, touch or key inputs, communications transceivers, and status circuitry through its extensive lead set. For reliable panel operation, define display timing and bus resources from the exact pin table, budget processor and peripheral current, plan decoupling around all supply pins, and validate display and touch interfaces across temperature and electrical-noise conditions.
推薦
Data-Acquisition Equipment
ATSAM4E16EA-AN is well matched to compact data-acquisition equipment that coordinates sensors, local processing, storage, and host communication. The 120 MHz Cortex-M4 core supports real-time sampling control and numerical routines, while the floating-point unit helps implement filtering, calibration, scaling, and statistical calculations. Its confirmed 1 MB Flash capacity can hold acquisition firmware, calibration coefficients, and device configuration. Depending on the selected device functions, the microcontroller can supervise sensor inputs, timestamp measurements, and transfer results through an external communications interface. The 144-LQFP package provides a conventional surface-mount option with many external connections, allowing dedicated signal routing for analog front-end control, digital sensors, status indicators, and isolated communications. Final qualification should verify analog support, converter interfaces, trigger latency, input range, timing accuracy, and thermal performance in the completed instrument enclosure.

Medical and Laboratory Instruments
ATSAM4E16EA-AN can support the control architecture of laboratory and medical-instrument platforms where a deterministic microcontroller coordinates sensors, actuators, displays, and service interfaces. The 120 MHz 32-bit Cortex-M4 core provides responsive computation, and its floating-point unit assists with filtering and calibration routines. With 1 MB of internal Flash, the device can retain substantial application firmware and parameter data while external nonvolatile storage handles records or firmware updates. The 144-LQFP package offers a broad pin count for digital sensor connections, communication ports, and user controls. Because medical equipment may impose specialized documentation, isolation, safety, and quality-system requirements, engineers should evaluate the exact device grade and applicable regulatory controls. Confirm the power architecture, separation boundaries, watchdog strategy, fault behavior, and validation requirements before incorporating the microcontroller into a clinical system.
推薦
IoT and Edge Sensor Nodes
ATSAM4E16EA-AN supports IoT and edge sensor nodes that need local processing before information is sent over a network. The 120 MHz Cortex-M4 core can execute protocol stacks, sensor fusion, filtering, and device-state logic, while the floating-point unit improves the efficiency of numerical sensor processing. Its 1 MB internal Flash provides room for connected-device firmware, networking configuration, and calibration data. In an edge node, the microcontroller can collect measurements, validate sensor data, update a local display or actuator, and manage a communications module over serial or parallel interfaces. The 144-LQFP package is appropriate for boards that value a generous lead count and inspectable surface-mount assembly. Deployment planning should still account for radio-module power, antenna integration, security provisioning, thermal cycling, low-power modes, and exact peripheral availability. Confirm those functions in the manufacturer documentation for the selected device revision.

主要差異化特點
- Confirmed 1 MB internal Flash allocation (對比ATSAM4E8EA-AN)
- Direct fit for an LQFP-based board (對比ATSAM4E16EA-CU)
- Floating-point acceleration within the Cortex-M4 core (對比ATSAM4E16EA-AUR)
設計說明
Route the ATSAM4E16EA-AN power, ground, clock, and high-speed interface nets according to the manufacturer reference layout and pin-description table. Place required bypass capacitors close to their associated supply pins and provide a solid, low-impedance ground plane. Because the 144-LQFP footprint provides many signal and power connections, inspect the assembly for accidental solder bridges and confirm pin-one orientation against the package drawing before releasing the first board.
Do not treat every ATSAM4E16EA ordering suffix as mechanically or electrically interchangeable. The ATSAM4E16EA-CU comparison record identifies LFBGA, while ATSAM4E16EA-AN is LQFP; changing between them requires a new land pattern and routing review. Also confirm the exact silicon revision, temperature grade, packing option, and peripheral pin multiplexing before firmware or PCB release.
Determine supply currents and rail sequencing from the manufacturer electrical characteristics and the enabled peripheral set. Processor activity, external-interface loading, and output-pin states can change board demand, so a complete power budget is more useful than a clock-rate estimate. Include startup current, regulator tolerance, capacitor effective capacitance, and worst-case peripheral states when sizing the supply network.
Validate junction temperature using the package thermal information, actual PCB copper area, airflow, and the highest expected ambient temperature. The 144-lead LQFP provides many connection points for thermal spreading, but board construction and enclosure conditions can dominate heat dissipation. Measure temperature rise on production-intent hardware and verify that the selected revision, grade, and operating environment remain within its documented limits.
Microchip recommends considering Revision B for new prototype and production designs. Resolve the device revision before committing software, masks, or production quantities, and review the associated errata and migration information. Keep firmware startup checks and peripheral configuration aligned with the selected revision so that alternate-function settings, clock behavior, and peripheral resets match the silicon actually fitted.
