ATXMEGA16E5-MN - 32MHz 16KB AVR XMEGA | Microchip Technology
Référence : ATXMEGA16E5-MN ✓ ActifATXMEGA16E5-MN Présentation
An 8/16-bit AVR microcontroller is a compact embedded-processing device that combines a RISC processor core, program memory, data memory, interrupt handling, timers, communication interfaces, and analog or timing peripherals in one integrated circuit. The XMEGA E5 family is positioned between simple 8-bit controllers and more resource-intensive 16-bit embedded processors, making it useful for compact control, measurement, communications, and signal-processing nodes.
Key features of the ATXMEGA16E5-MN include 16 KB of flash memory, 2 KB of SRAM, 512 bytes of EEPROM, a 32 MHz clock, an eight-channel event system, and a programmable multilevel interrupt controller. Read-while-write flash operation can support firmware updates when the application reserves an appropriate boot section. Its 1.6 V to 3.6 V operating range supports common low-voltage embedded systems, while the 32-VQFN package supports compact board layouts.
The E5 family uses the AVR enhanced RISC architecture and integrates eight-channel event-system hardware alongside a multilevel interrupt controller. This architecture is useful when timing relationships between counters, timers, and external events must remain deterministic. The 16 KB flash capacity balances firmware footprint against SRAM and EEPROM constraints, while the dedicated 4 KB boot-code section provides a practical separation between application code and startup or update logic.
Typical uses include industrial sensor nodes, compact data-acquisition controllers, motor-control peripherals, communications modules, compact industrial controls, and embedded accessories requiring an event system or programmable interrupt handling. Designers should confirm peripheral assignments, voltage limits, clock requirements, and programming support for the intended board before production release.
For PCB implementation, place decoupling capacitors close to the supply pins and route programming and communication signals away from noisy switching stages. The small 5 x 5 mm VQFN footprint also demands careful assembly planning because individual pins are difficult to probe after soldering. The manufacturer datasheet is the controlling document for pin functions, electrical limits, and recommended land pattern.
This product page consolidates the ATXMEGA16E5-MN memory configuration, operating limits, package information, engineering guidance, comparison criteria, and sourcing workflow. It is intended to accelerate component selection and design review by connecting the device specifications with practical low-power embedded-control requirements.

Applications typiques
ATXMEGA16E5-MN convient pour 6 applications: Industrial Sensor and Condition Monitoring, Compact Data-Acquisition Controller, Low-Power Communications Module, Motor Control and Timing Peripheral, Embedded Control and Security Peripheral, Compact Consumer or Utility Controller.
Industrial Sensor and Condition Monitoring
The ATXMEGA16E5-MN fits compact condition-monitoring nodes that must combine sensor acquisition, local filtering, status reporting, and low-power behavior in one controller. Its 32 MHz processing rate supports responsive foreground tasks, while 2 KB of SRAM provides working space for sampled data and protocol buffers. The eight-channel event system and programmable multilevel interrupt controller are valuable when counters or external sensor events must be timestamped deterministically. Its 1.6 V to 3.6 V operating range also suits low-voltage industrial sensing chains. Design the power subsystem for the required sampling interval, and use the 4 KB boot section only if application firmware and field-update requirements are planned around that boundary.
Recommandé
Compact Data-Acquisition Controller
The ATXMEGA16E5-MN is appropriate for a small acquisition controller where a 32 MHz MCU must gather data, buffer it in SRAM, and transfer it through a serial interface. Its 16 KB ISP flash accommodates the acquisition firmware, configuration tables, and a boot area of up to 4 KB, while 512 bytes of EEPROM can retain calibration values or operating flags when the application requires nonvolatile parameters. The event system can coordinate timing among counters and external triggers without depending entirely on software polling. A 32-VQFN 5 x 5 mm package helps minimize board area, although careful land-pattern and assembly planning is needed. Validate acquisition timing, trigger latency, and buffer use against the specific peripheral configuration.
Recommandé
Low-Power Communications Module
The ATXMEGA16E5-MN can serve as the protocol controller in a compact communications module requiring an 8/16-bit RISC processor, local nonvolatile storage, and deterministic event handling. The 32 MHz clock provides substantial processing headroom for framing, checksums, and protocol state management, while the 1.6 V to 3.6 V range supports low-voltage radio and sensor interfaces. An eight-channel event system can connect communication timing to counters or external interrupt sources, reducing polling delays. The 32-VQFN package is appropriate for space-constrained boards, but antenna and power-supply isolation remain layout priorities. Confirm the module's idle-current target, clock-startup behavior, and brownout requirements before production because system power depends on the selected operating mode.
Recommandé
Motor Control and Timing Peripheral
The ATXMEGA16E5-MN is suitable for a timing-intensive motor-control or sequencing peripheral when its timers, event system, and interrupt architecture can satisfy the required update rate. At 32 MHz, the controller can execute motion logic and diagnostics while coordinating external events through dedicated hardware. Its 16 KB flash provides space for control algorithms and parameter handling, and its compact 32-VQFN footprint fits densely assembled control boards. The controller should not be assumed to provide every motor-control peripheral required by a design; verify PWM channel count, compare outputs, pin multiplexing, and timer cascading in the manufacturer datasheet. Use external protection components where current, voltage, or fault conditions exceed the MCU's ratings.
Recommandé
Embedded Control and Security Peripheral
The ATXMEGA16E5-MN fits a compact embedded-control peripheral that must authenticate or store configuration while also handling local I/O. The dedicated 4 KB boot-code section can separate startup, recovery, or update logic from the 16 KB application area, and the 512-byte EEPROM supports small nonvolatile settings such as calibration data or device counters. Its multilevel interrupt controller helps prioritize external events, while the 32 MHz core supports protocol processing and control updates. Security requirements should be assessed independently rather than inferred from the boot section. Confirm supported cryptographic capabilities, intended update workflow, and tamper-response requirements before choosing this controller for a security-critical role.
Recommandé
Compact Consumer or Utility Controller
The ATXMEGA16E5-MN can support compact consumer accessories and utility controllers that combine local logic, serial communication, and nonvolatile configuration in a small board. Its 16 KB flash accommodates a focused firmware image, 2 KB of SRAM supports protocol and display handling, and the EEPROM retains small configuration changes. The low 1.6 V minimum operating voltage can simplify power-tree design when the surrounding system operates below 3.3 V. The 32-VQFN package reduces board footprint, but manufacturing must include adequate solderable area and inspection coverage. Confirm whether the required consumer temperature range, enclosure heating, and standby-current targets meet the device's documented operating profile before production.

Notes de conception
Design the 32-VQFN 5 x 5 mm land pattern from the Microchip Technology package drawing and recommended footprint. Place input and output decoupling capacitors immediately adjacent to their intended supply pins, and keep the exposed thermal or ground connection uninterrupted where required by the package drawing. Because the component has closely spaced terminals, verify solder paste volume, stencil aperture ratios, assembly profile, and post-reflow inspection coverage before releasing the PCB.
Use the manufacturer electrical limits to define the power tree and decoupling strategy for the 1.6 V to 3.6 V operating range. Confirm brownout behavior, clock-startup requirements, I/O drive limits, and the maximum combined current before adding external loads to a port. Separate sensitive analog or communications paths from switching supplies and preserve a clean return path beneath the MCU. Validate startup and shutdown behavior across the slowest intended power-supply ramp.
Use the eight-channel event system and programmable interrupt controller to reduce dependence on polling, but verify signal routing for every event source and interrupt priority. Keep the 32 MHz clock path short and follow the manufacturer's recommended grounding and decoupling arrangement. Programmer, UART, and other communication test points should remain accessible without creating long high-impedance traces that could increase coupling or pickup noise. Review unused pins against the datasheet's required termination rather than leaving their configuration implicit.
Do not treat the 32-VQFN footprint alone as proof that another XMEGA E5 ordering code is a drop-in replacement. Compare suffix-specific temperature grade, flash configuration, SRAM, EEPROM, boot section, peripheral availability, fuse behavior, and qualification status. When moving from ATXMEGA16E5-MN to ATXMEGA32E5-MN, recalculate the memory map and retest firmware timing. When moving to ATXMEGA8E5-MN, verify that the 8 KB flash budget is sufficient.
