ATSAM4E8EA-ANR - 120MHz Cortex-M4 512KB Flash MCU | Microchip (Tape & Reel)
MPN: ATSAM4E8EA-ANR ✓ Hoạt độngATSAM4E8EA-ANR Tóm tắt
A microcontroller is a programmable semiconductor that combines a processor core, memory, and peripherals on one integrated circuit. The Cortex-M4 core belongs to the ARM processor family and uses a reduced instruction set architecture tailored for embedded control. Within the product hierarchy, ATSAM4E8EA-ANR is an ARM-based MCU, a microcontroller, and an integrated circuit. Its 120 MHz operating frequency allows software to execute control loops, communication protocols, and data-processing tasks while dedicated peripherals handle time-sensitive interface functions.
The verified product listing identifies four headline characteristics: a 32-bit ARM Cortex-M4 processor, a maximum clock speed of 120 MHz, 512 KB of flash memory, and a 144-LQFP 20 mm by 20 mm package. These figures make the device suitable for industrial controllers, embedded automation equipment, communication modules, human-interface systems, and connected products where substantial program storage and a moderate pin count are required. The large leaded package also supports designs using fine-pitch PCB routing and provides a larger thermal and pin-termination surface than compact leadless packages.
The SAM4E family combines a high-performance processor core with embedded memories and communication peripherals. At 120 MHz, the processor provides substantially more instruction throughput than many lower-clock 8-bit or 32-bit microcontrollers. The 512 KB flash permits larger firmware, bootloaders, protocol stacks, and application logic to coexist, while SRAM and external-interface details remain unavailable in the supplied verified data. Review the complete manufacturer documentation before assigning memory sizes, peripheral channels, clock configurations, or interrupt resources to the design.
Typical deployments include industrial machine controls, motor-control adjuncts, building automation controllers, data acquisition units, networking equipment, and embedded gateways. In each case, the 120 MHz Cortex-M4 core can execute application logic while the MCU architecture supports deterministic peripheral operation. The 144-LQFP package is particularly suitable for prototypes and industrial boards where through-hole assembly, inspection, or rework is preferred over very fine-pitch BGA handling.
The primary design consideration is that component identity alone does not establish board-level compatibility. Engineers must verify power architecture, clocking, pin multiplexing, peripheral availability, package dimensions, programming interfaces, and memory requirements against the manufacturer datasheet. The available web evidence also identifies a newer revision recommendation for new designs, so ATSAM4E8EA-ANR should be checked for revision and lifecycle status before production release.
This page consolidates verified distributor specifications, current commercial availability, package information, and engineering selection guidance. It also separates confirmed facts from unavailable technical details, allowing procurement and design teams to identify the remaining datasheet checks without mistaking inferred or unreported parameters for guaranteed specifications.

Ứng dụng tiêu biểu
ATSAM4E8EA-ANR phù hợp cho 6 Áp dụngs: Industrial Machine Controllers, Building Automation Equipment, Embedded Data Acquisition, Communication Gateways, Motor and Power-System Control, Connected Embedded Products.
Industrial Machine Controllers
The ATSAM4E8EA-ANR fits industrial machine controllers that require real-time application processing and a substantial embedded program area. Its verified 120 MHz ARM Cortex-M4 core can execute motion-control logic, state machines, diagnostics, and communication tasks, while 512 KB of flash provides room for firmware, parameter tables, and update code. The 144-LQFP 20 mm by 20 mm package is also practical for industrial controller prototypes and assemblies where leaded-package inspection and rework are valuable. Before final selection, engineers must confirm operating temperature, supply limits, timer resources, analog channels, communications peripherals, and functional-safety requirements against the manufacturer datasheet.
Building Automation Equipment
ATSAM4E8EA-ANR can serve as the central controller in a building-automation node combining scheduling logic, sensor processing, and network management. The 120 MHz Cortex-M4 processor provides enough throughput to service multiple communication tasks and supervisory routines, and the 512 KB flash capacity supports embedded networking stacks alongside application firmware. Its large 144-lead LQFP footprint leaves access to a high pin count for external interfaces and board-level debug. The verified data does not confirm the exact communication peripherals, I/O count, or operating-temperature grade, so those details must be checked before assigning Ethernet, sensor, or relay interfaces.
Embedded Data Acquisition
The ATSAM4E8EA-ANR is applicable to data-acquisition equipment where local filtering, calibration handling, and protocol conversion must run alongside sensor stimulation. Its 32-bit Cortex-M4 architecture at up to 120 MHz supports computationally heavier control and buffering than a basic low-clock microcontroller, while 512 KB of flash can store firmware and lookup data. The 144-LQFP package provides a large number of physical pins for external signal conditioning and debug access. Because ADC resolution, sample rate, input count, reference voltage, SRAM, and timing performance are not present in the supplied records, these functions require direct datasheet verification.
Communication Gateways
ATSAM4E8EA-ANR can support a protocol-conversion or embedded gateway design that must coordinate multiple serial interfaces and maintain deterministic control behavior. The verified 120 MHz processing rate and 512 KB flash are useful for protocol stacks and application logic, while the 144-LQFP package provides a practical choice for leaded industrial boards. Selection should emphasize the peripheral set actually present in the exact device revision, including UART, SPI, I2C, Ethernet, USB, and CAN capabilities, none of which are quantified in the supplied web snippets. Also verify package pin multiplexing and external transceiver requirements before treating the MCU as a drop-in gateway controller.
Motor and Power-System Control
The ATSAM4E8EA-ANR is suitable for supervisory control in motor-drive and industrial power-system equipment when a fast 32-bit processor and 512 KB flash are required. The Cortex-M4 core can execute current-loop support tasks, fault handling, parameter processing, and communications logic while external power semiconductors and sensors perform the high-energy conversion. The MCU is not itself the power switch and does not replace gate drivers, current sensing, or isolation components. Engineers must confirm timer channels, PWM resolution, analog interfaces, fault pins, operating temperature, and safety requirements in the official documentation before using this part in a motor-control design.
Connected Embedded Products
ATSAM4E8EA-ANR can act as the application processor in a connected embedded product that needs local control, firmware storage, and extensible serial connectivity. The 120 MHz Cortex-M4 core is suited to running device logic alongside communication tasks, and the verified 512 KB flash supports a bootloader and application firmware without an external program-memory device. The 144-LQFP package also makes the part accessible for prototype assembly and signal probing. Exact wireless, Ethernet, USB, security, and peripheral capabilities are not confirmed by the supplied records, so designers should treat this as a general-purpose candidate rather than assume any particular connectivity block is present.

Ghi chú thiết kế
Use the official ATSAM4E8E 144-LQFP 20 mm by 20 mm package drawing as the controlling source for land patterns. Confirm pad dimensions, pin numbering, exposed thermal-pad treatment, solder-mask clearance, and courtyard before PCB release. The verified distributor data establishes the package family and dimensions but does not provide a complete pin table, so schematic symbols and footprints must not be inferred from visually similar LQFP devices. Also preserve access to all programming, reset, clock, and ground pins to simplify boundary scan and hardware troubleshooting.
Verify the exact power-supply and I/O voltage limits, decoupling requirements, and internal regulator architecture from the manufacturer datasheet before connecting external signals. ATSAM4E8EA-ANR is a 120 MHz MCU, so switching activity and processor load can affect supply-current behavior even though the supplied source does not provide a current-consumption specification. Place required bulk and high-frequency decoupling capacitors at the device supply pins according to the reference design, and include adequate ground-plane continuity beneath the large LQFP footprint.
Do not treat ATSAM4E8EA-ANRR, ATSAM4E8EA-AU, or ATSAM4E8EA-AUR as distinct drop-in devices merely because their order codes look different. The verified records identify ATSAM4E8EA-ANRR with the same 144-LQFP package, but it is a reel-packaging form of the same family and is not an engineering alternative. Likewise, ATSAM4E16EA-AU may offer different memory resources and cannot be treated as pin-compatible without a full family datasheet comparison. This distinction prevents accidental changes to shipment method, firmware assumptions, or PCB requirements.
Microchip's verified ATSAM4E8E family result recommends considering revision B for prototypes and production. Before releasing a new ATSAM4E8EA-ANR design, compare the current silicon revision's errata, pin behavior, peripheral differences, and lifecycle notices against the revision being sourced. A distributor's active listing does not guarantee that the older ordering code is the preferred production choice. Document the approved revision and any board-impacting changes in the production BOM and test plan.
Thông tin tuân thủ
The supplied verified sources do not provide an explicit compliance declaration for ATSAM4E8EA-ANR. Confirm RoHS, REACH, AEC-Q100, lead-free, halogen-free, and conflict-mineral status using current documentation for the exact ordering code and revision.
