MPN: ATSAM4E16EA-AN ✓ AktifATSAM4E16EA-AN Ringkasan
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.

Catatan Desain
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.
