ATXMEGA8E5-AN - 32MHz 8KB AVR Microcontroller | Microchip
Référence : ATXMEGA8E5-AN ✗ Fin de vieATXMEGA8E5-AN Présentation
A microcontroller is a programmable embedded-control IC that integrates a processor core, memory, timers, communication interfaces, and peripherals on one device. The AVR XMEGA E5 belongs to the 8/16-bit AVR enhanced RISC microcontroller family, combining low-power operation with event-driven control and read-while-write flash support. This makes it useful for compact control systems that need deterministic timing and flexible peripheral interconnection.
The ATXMEGA8E5-AN combines 8 KB ISP flash with an additional 2 KB boot-code section, 512 bytes EEPROM, and 1 KB SRAM. Its operating supply range is listed by Mouser as 1.6 V to 3.6 V, with an operating-temperature marking of 105C. The family documentation identifies a 32-pin device configuration, while the distributor listings identify this exact orderable part as ATXMEGA8E5-AN in a 32-TQFP package. The ATXMEGA family is intended for applications where compact code execution, EEPROM retention, and event-system peripherals are valuable.
The eight-channel event system is a key architectural feature. It allows hardware peripherals and external signals to communicate through event resources, reducing the need for polling and helping coordinate timing-sensitive tasks. The integrated memory arrangement also supports firmware storage, boot loading, and working data in a single controller. Compared with a larger general-purpose MCU, the ATXMEGA8E5-AN offers a focused 8/16-bit platform with a small memory footprint and a 32 MHz clock.
Typical uses include industrial automation, sensor and actuator control, compact embedded instruments, motor-control support, communication-interface designs, and low-power control nodes. The exact peripheral mix, electrical limits, programming requirements, and package pin details should be confirmed against the Microchip family datasheet and the ATXMEGA8E5-AN ordering information before final PCB release.
Designers should preserve the required decoupling, oscillator layout, programming access, and unused-pin treatment recommended by the manufacturer. Firmware should be built for the ATxmega8E5 device definition and validated with the intended clock source and supply voltage. Because this page is assembled from distributor listings and the family datasheet, package suffixes and purchasing conditions should be checked against the latest authorized source.
This page combines verified distributor specifications, the official Microchip product description, family datasheet information, application guidance, and sourcing links to support component selection and engineering review.

Applications typiques
ATXMEGA8E5-AN convient pour 6 applications: Industrial Automation Controller, Sensor and Actuator Interface Hub, Compact Embedded Instrument, Low-Power Communication Node, Motor and Timing Control Module, Programmable Control and Data Acquisition.
Industrial Automation Controller
The ATXMEGA8E5-AN is suitable for compact industrial control nodes that coordinate sensors, digital outputs, and timing events at up to 32 MHz. Its eight-channel event system can connect peripheral activities without relying entirely on software polling, while 8 KB flash and 1 KB SRAM provide room for focused control firmware. The 1.6 V to 3.6 V supply listing supports low-voltage designs, although the exact regulator, isolation, and environmental requirements must be verified for the final system.
Recommandé
Sensor and Actuator Interface Hub
Use the ATXMEGA8E5-AN as the central controller for a small sensor-and-actuator node when deterministic event handling and local nonvolatile storage are important. The eight-channel event system can coordinate timer, communication, and external-event activity, while 512 bytes EEPROM can retain calibration or configuration data. Firmware design should budget the available 8 KB flash and 1 KB SRAM carefully, and the final board must follow the manufacturer’s I/O, clock, and decoupling recommendations.
Recommandé
Compact Embedded Instrument
The ATXMEGA8E5-AN can serve as the control core of a compact measurement instrument when the application needs moderate processing speed and peripheral coordination without a large external memory system. Its 32 MHz maximum clock supports responsive control logic, and the event system can synchronize acquisition or control functions. Designers should verify the complete peripheral list, analog characteristics, timing limits, and pinout in the Microchip datasheet before assigning precision measurement functions.
Recommandé
Low-Power Communication Node
ATXMEGA8E5-AN is appropriate for a small communication node that needs local event-driven control around a serial transceiver. The 32 MHz clock provides control headroom, the boot-code section supports programmed startup behavior, and the event system can coordinate peripheral timing. Actual communication range, baud rate, sleep behavior, and transceiver compatibility are not supplied in the verified data and must be established from the selected peripheral configuration and the family datasheet.
Recommandé
Motor and Timing Control Module
The ATXMEGA8E5-AN can be evaluated for small motor-control or timing modules where the eight-channel event system assists with deterministic peripheral coordination. Its 32 MHz operation and 8/16-bit AVR instruction set are useful for real-time control loops, while 512 bytes EEPROM can hold operating parameters. A production design still requires application-specific transistor, driver, protection, current-sense, and thermal validation; the MCU itself does not provide a complete motor-power stage.
Recommandé
Programmable Control and Data Acquisition
ATXMEGA8E5-AN can act as a programmable control front end for compact data-acquisition systems when the application prioritizes low power, local control, and event-driven sequencing. The controller can manage configuration sequencing and external interfaces while storing firmware in 8 KB ISP flash and using 512 bytes EEPROM for persistent settings. For analog measurement accuracy, external converters, reference design, calibration, and signal-conditioning components should be selected separately and validated against the complete datasheet specifications.

Notes de conception
Design the ATXMEGA8E5-AN supply rail within the verified 1.6 V to 3.6 V listing and check the family datasheet for operating conditions at the selected clock. Place the required local decoupling capacitors close to the supply and ground pins, and keep switching-regulator layout separate from sensitive analog or communication paths. Validate startup, brownout, and current behavior on the final board.
Preserve the manufacturer’s recommended placement and routing for the oscillator, programming interface, reset circuitry, and decoupling. The 32-pin TQFP footprint has fine-pitch leads, so inspect solder-mask and paste patterns for manufacturing capability. Keep high-current outputs and external switching nodes away from clock and communication traces, and route ground returns with low loop area.
Do not assume that a device with the same XMEGA family name is a drop-in replacement. Confirm the exact ATXMEGA8E5 suffix, memory size, pin mapping, peripheral assignment, clock requirements, and package drawing. Also verify the toolchain device definition and programming settings; firmware compiled for a different XMEGA variant may not operate correctly on ATXMEGA8E5-AN.
Informations de conformité
The verified distributor data identifies a green component and lists a 105C temperature marking, but it does not explicitly establish RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for ATXMEGA8E5-AN.
