ATXMEGA16E5-AN - 32MHz 16KB AVR XMEGA | Microchip
料号： ATXMEGA16E5-AN ✓ 量产中ATXMEGA16E5-AN 概述
An 8/16-bit microcontroller is a programmable semiconductor that integrates a processor core, nonvolatile program memory, volatile working memory, peripherals, and I/O into one device. The AVR XMEGA family combines enhanced RISC architecture with an event system and programmable interrupt handling. This places the ATXMEGA16E5-AN in the embedded-control hierarchy of microcontroller, 8/16-bit MCU, low-power control, and programmable logic device.
Key features include 16 KB of ISP flash, a 4 KB boot-code section, read-while-write capability, 2 KB SRAM, and 512 B EEPROM. The eight-channel event system and programmable multi-level interrupt controller support deterministic event handling. Three flexible 16-bit timer/counters with compare modes and PWM, plus one 16-bit real-time counter, cover timing, waveform generation, and periodic control requirements.
The 26 general-purpose I/O lines provide connections for sensors, actuators, communication interfaces, and status indicators. A 32 MHz clock allows the CPU to process control logic and peripheral events efficiently, while the XMEGA E5 architecture is designed for both performance and low power. Its operating supply range of 1.6 V to 3.6 V supports embedded systems using low-voltage rails.
Typical uses include industrial sensor controllers, compact automation equipment, motor and valve control, lighting systems, measurement instruments, and low-power IoT nodes. The combination of event-driven peripherals, PWM-capable timers, and serial interface resources makes the device suitable for designs that require deterministic timing without a large external peripheral set.
When laying out the PCB, place decoupling capacitors close to the supply pins and route sensitive signals away from switching nodes. Confirm the exact 32-pin TQFP pin assignments, programming connections, and peripheral multiplexing in the manufacturer datasheet before finalizing tracks and firmware.

典型应用
ATXMEGA16E5-AN 适用于 6 应用s: Industrial Sensor Controller, Motor and Valve Control, LED Lighting Controller, Measurement and Instrumentation, Low-Power IoT Node, Communication Interface Hub.
Industrial Sensor Controller
The ATXMEGA16E5-AN fits compact sensor-control nodes that need 26 general-purpose I/O lines and deterministic event handling without an external controller. Its 32 MHz execution rate provides headroom for sampling, filtering, and control logic, while the eight-channel event system can connect timers and peripherals without continuous polling. The 16 KB ISP flash and 2 KB SRAM provide useful capacity for protocol handling and local data buffering. Because the device operates from 1.6 V to 3.6 V, it also supports compact low-voltage sensing boards.
推荐
Motor and Valve Control
The three flexible 16-bit timer/counters in the ATXMEGA16E5-AN make it suitable for motor, valve, and actuator control where compare outputs and PWM are useful. The 32 MHz core can coordinate multiple timing functions while the event system links peripheral events to interrupt handling. With 26 I/O lines, a board can combine control outputs, limit inputs, status signals, and communications. Designers should still check the exact timer pin multiplexing and current ratings of external drivers in the manufacturer datasheet.
推荐
LED Lighting Controller
The ATXMEGA16E5-AN can drive programmable LED effects, status indicators, and lighting sequences using its PWM-capable 16-bit timers. Thirty-two megahertz operation leaves room for animation, calibration, and communication tasks beyond simple timing. The 2 KB SRAM is useful for display buffers and effect parameters, while the 16 KB flash can hold multiple lighting profiles. Its low-voltage 1.6 V to 3.6 V operating range suits compact LED modules, subject to the output-current and timing-pin requirements of the selected LED driver.
推荐
Measurement and Instrumentation
The ATXMEGA16E5-AN is appropriate for compact measurement equipment that needs multiple timers, event-based acquisition, and moderate local processing. Its 32 MHz clock supports faster sampling loops, while three 16-bit timer/counters can handle measurement intervals, capture functions, and PWM outputs. The 512-byte EEPROM preserves small configuration values, while 2 KB SRAM supports acquisition buffers and interface state. For high-accuracy analog measurement, the MCU can coordinate external converters and sensors while keeping control logic on the same board.
推荐
Low-Power IoT Node
The ATXMEGA16E5-AN supports low-power IoT nodes that combine sensor conditioning, local logic, and communications in a 1.6 V to 3.6 V design. Its 2 KB SRAM and 16 KB flash are suitable for small protocol stacks and event-driven control, while the event system can reduce reliance on continuous CPU polling. Low-power operation still depends on the selected clock mode, active peripherals, sleep configuration, and the behavior of attached sensors. Validate the duty cycle and wake-up sequence during firmware and board-level testing.
推荐
Communication Interface Hub
The ATXMEGA16E5-AN can serve as a protocol hub or bridge when a design needs several serial functions and event-driven data movement. The 26 I/O lines and three 16-bit timers provide resources for serial links, status signaling, baud timing, and local buffering. At 32 MHz, it can handle framing, protocol conversion, and supervisory logic while the event system coordinates peripheral activity. Pin multiplexing must be reviewed against the selected communication peripherals, and firmware should include flow control for sustained high-volume transfers.

关键差异点
- Balanced memory capacity within the XMEGA E5 family （对比 ATXMEGA8E5-AN)

- Event-driven control with three PWM-capable timers （对比 ATXMEGA8E5-AN)
设计说明
Place the required supply-decoupling capacitors adjacent to the ATXMEGA16E5-AN power pins and provide a short return path to the ground plane. Route high-current switching-node traces and external clock or sensor signals away from the MCU supply area. Because several XMEGA peripheral functions can share the same pins, freeze the pin-assignment table from the datasheet before routing the 32-pin TQFP footprint.
Design the 1.6 V to 3.6 V supply rail so it remains within the ATXMEGA16E5-AN operating limits at the highest specified processing frequency, peripheral load, and temperature. Separate noisy switching-regulator output from sensitive analog sections when possible. Confirm startup behavior, power-supply sequencing, and brownout conditions in the manufacturer electrical-characteristics documentation before production release.
Do not select ATXMEGA8E5-AN merely because it uses the same 32-pin family package: its 8 KB flash and 1 KB SRAM are lower than the target's 16 KB and 2 KB. Likewise, verify the exact suffix, package dimensions, temperature marking, and programming interface for ATXMEGA16E5-AU. Any substitution should be checked against compiled code size, stack requirements, peripheral multiplexing, and boot configuration.
