ATXMEGA8E5-AUR - 32MHz 8KB AVR Microcontroller | Microchip Technology
部品番号: ATXMEGA8E5-AUR ✓ 生産中ATXMEGA8E5-AUR 概要
An 8/16-bit microcontroller is a programmable semiconductor that executes firmware, reads sensors, controls outputs, and manages communication interfaces. The AVR XMEGA family uses an enhanced RISC architecture and provides dedicated event-system hardware, timers, serial interfaces, and analog peripherals. Within the broader hierarchy of embedded semiconductors, the ATXMEGA8E5-AUR is a microcontroller with integrated nonvolatile memory and mixed-signal peripherals rather than a general-purpose processor or discrete logic device.
The principal features include 32 MHz operation, 8 KB of in-system self-programmable flash with read-while-write capability, 1 KB of SRAM, 512 bytes of EEPROM, and an eight-channel event system. A programmable multi-level interrupt controller supports deterministic event handling, while the operating-voltage range of 1.6 V to 3.6 V supports low-voltage embedded systems. The device also provides the peripheral resources typical of an industrial-oriented XMEGA E5 design.
The ATxmega E5 architecture combines a high-performance AVR core with dedicated hardware for timers, communications, and event routing. Its event system can connect multiple peripheral events without requiring continuous central-processor polling, helping reduce interrupt overhead in control loops. Flash memory supports in-system programming, and the dedicated boot section allows firmware to reserve space for application startup or field-update routines. The 32-pin TQFP package exposes the GPIO, power, ground, reset, clock, and analog-reference connections required by the family device.
Typical uses include industrial sensor nodes, compact motor-control modules, building-automation controllers, instrumentation peripherals, low-power monitoring equipment, and embedded communication gateways. The combination of 8 KB flash, 1 KB SRAM, and an event system is useful when a compact control product requires deterministic peripheral interactions without the memory overhead of a larger application processor.
Designers should budget flash and SRAM carefully because the ATXMEGA8E5-AUR is optimized for compact control tasks rather than large graphical or network-heavy workloads. External decoupling, careful clock routing, and a stable reference design remain important at 32 MHz. The 32-pin TQFP footprint also requires a PCB layout that provides adequate copper access around the exposed leads.
This product page combines the manufacturer’s technical specifications, pin-package guidance, verified source links, and application-focused design guidance. It also explains the limitations of currently confirmed replacement parts so engineers can distinguish a true same-footprint option from a device that merely belongs to the same AVR family.

主な用途
ATXMEGA8E5-AUR の用途: 6 件s: Industrial Sensor Node, Building Automation Controller, Compact Motor-Control Module, Low-Power Monitoring Equipment, Instrumentation Signal Interface, Embedded Communication Gateway.
Industrial Sensor Node
The ATXMEGA8E5-AUR fits compact industrial sensor nodes because its 1.6 V to 3.6 V operating range supports low-voltage sensing platforms while the 32 MHz AVR core handles sampling logic, configuration, and local diagnostics. Its eight-channel event system can route timer and peripheral events directly, reducing processor polling in systems that must respond predictably. The 8 KB flash stores application firmware, and the separate 2 KB boot section can support controlled startup or update routines. Use the manufacturer pin configuration to place decoupling capacitors, clock components, and programming interfaces correctly.
おすすめ
Building Automation Controller
For building-automation endpoints, the ATXMEGA8E5-AUR can consolidate periodic sensing, actuator control, and communication handling in a low-power embedded controller. Its programmable multi-level interrupt system and eight-channel event system support deterministic handling of timers, external inputs, and peripheral events, while 1 KB of SRAM is suitable for compact protocol buffers. The 1.6 V to 3.6 V range simplifies integration with low-energy sensor rails. Keep the device away from noisy switching stages and follow the manufacturer’s recommended power and layout practices.
おすすめ
Compact Motor-Control Module
The ATXMEGA8E5-AUR is suitable for compact motor-control modules that require fast event coordination, local control logic, and a small memory footprint. Its eight-channel event system can connect timer and peripheral events for deterministic commutation or control sequencing, while the 32 MHz CPU provides room for supervisory logic and diagnostics. The 512-byte EEPROM can retain calibration values. Designers should verify the exact timer, analog, and PWM resources against the datasheet and isolate motor noise from sensitive control circuitry.
おすすめ
Low-Power Monitoring Equipment
The ATXMEGA8E5-AUR works well in battery-assisted monitoring equipment where a 1.6 V to 3.6 V supply and compact memory are important. Its low-power XMEGA E5 platform can remain in resource-saving operating states between measurements, while the event system allows scheduled sensor activity to occur without continuous polling. Nonvolatile 8 KB flash stores firmware, 512-byte EEPROM retains small configuration records, and the 32-pin TQFP package supports a compact board. Actual battery performance depends on sleep-mode settings, sensor current, and leakage.
おすすめ
Instrumentation Signal Interface
The ATXMEGA8E5-AUR can serve as the supervisory controller in compact instrumentation interfaces that combine measurement acquisition, calibration storage, and a communications link. Its 32 MHz processing rate supports protocol handling and control tasks, while 512 bytes of EEPROM are useful for small calibration tables and the 2 KB boot section can support controlled initialization. The 1.6 V to 3.6 V range integrates naturally with low-voltage sensor front ends. Confirm analog-channel availability, reference-voltage requirements, and acquisition timing in the manufacturer datasheet before finalizing the signal path.
おすすめ
Embedded Communication Gateway
The ATXMEGA8E5-AUR is appropriate for small communication gateways that translate sensor or control data rather than perform high-end protocol processing. Its 8 KB flash accommodates focused firmware, 1 KB of SRAM supports limited packet handling, and the event system can coordinate serial reception, timers, and status indicators. The 32-pin TQFP package provides access to the E5 family’s GPIO and communication peripherals in a surface-mount design. Select it when firmware size remains controlled; move to a larger E5 device when buffering, protocol stacks, or concurrent services exceed the available memory.

主な差別化要因

- Low-voltage operation in a compact surface-mount footprint （vs ATXMEGA8E5-ANR)
設計ノート
Route the 32-pin TQFP footprint from the manufacturer package drawing and preserve access to all programming and reset pins. Place the required input and output decoupling capacitors adjacent to their corresponding power pins, and keep clock-trace routing short. Because the ATXMEGA8E5-AUR can operate at 32 MHz, minimize long parallel runs beneath noisy digital or switching nodes.
Design the supply path for the documented 1.6 V to 3.6 V operating range, including startup and transient requirements for connected peripherals. Use separate low-impedance branches where practical for the MCU and analog circuitry. Verify brownout behavior, clock stability, and the voltage required by attached sensors rather than assuming that the MCU supply range alone covers the complete board.
Do not select a higher-memory ATxmega E5 device as a direct substitute solely because it uses a similar package. The 16E5 and 32E5 variants increase Flash and SRAM relative to the 8E5 device, changing code and memory planning. When considering ATXMEGA8E5-ANR, confirm its suffix-specific temperature grade, pin definitions, programming configuration, and qualification requirements before releasing it to production.
Use the event-system capability to avoid unnecessary polling, but preserve deterministic timing through correctly configured peripherals and interrupts. Keep analog inputs away from switching-node currents and high-speed clock traces. If the board includes an external oscillator, follow the manufacturer’s recommended oscillator and load-capacitor arrangement to avoid startup failures or clock drift.
