ATXMEGA64C3-AN - 32MHz 64KB AVR XMEGA | Microchip
N.º de pieza: ATXMEGA64C3-AN ✓ ActivoATXMEGA64C3-AN Descripción general
An 8/16-bit AVR XMEGA microcontroller is an embedded processing device that combines a Harvard-style AVR architecture, programmable Flash memory, data EEPROM, SRAM, event handling, interrupts, and multiple digital and analog peripherals. XMEGA devices sit between simple 8-bit microcontrollers and more complex 32-bit processors, offering deterministic event-driven behavior and a broad peripheral set for compact control systems.
The ATXMEGA64C3-AN provides 64 KB of in-system programmable Flash, including an 8 KB boot-code section that supports read-while-write operation. Its 2 KB EEPROM retains configuration and calibration parameters without occupying SRAM, while 4 KB of SRAM supports protocol parsing, data acquisition, control state, and stack operations. The 32 MHz operating frequency provides additional timing margin for communication, sampling, and multi-peripheral workloads.
Its four-channel event system allows signals from timers, analog comparators, input-change interrupt sources, and other peripherals to trigger actions through a configurable event routing matrix. This hardware event path reduces polling overhead and helps designers implement responsive control without routing every event through the CPU. The device also supports a programmable multilevel interrupt controller for organized handling of concurrent peripheral events.
Typical uses include industrial control modules, data acquisition systems, sensor interfaces, communication equipment, compact industrial automation, and embedded consumer devices. Its combination of EEPROM, SRAM, event-system hardware, and a 1.6 V to 3.6 V supply range is useful where peripheral integration and deterministic event handling matter more than a large general-purpose processor core.
When designing the PCB, reserve the 64-pin TQFP footprint, verify the pin assignments for the selected peripherals, and route clock, programming, and decoupling connections according to the manufacturer pinout and layout guidance. Pay particular attention to startup behavior and the separation between high-current I/O paths and sensitive analog or clock nets.
This product page combines the manufacturer specifications with practical device-selection guidance, application fit, package information, and a parameter comparison. It focuses on engineering characteristics that determine whether the ATXMEGA64C3-AN belongs on an existing 64-pin TQFP design and what must be checked before firmware or hardware changes are committed.

Aplicaciones típicas
ATXMEGA64C3-AN es adecuado para 6 aplicacións: Industrial Sensor Acquisition, Communication Gateway Controller, Compact Automation Controller, Data Logger with Local Storage, Low-Power Embedded Control, Connected Control and Monitoring Node.
Industrial Sensor Acquisition
The ATXMEGA64C3-AN fits compact sensor-acquisition equipment that needs local processing without a large processor footprint. Its 32 MHz clock provides timing margin for sampling and filtering, while 64 KB Flash accommodates acquisition routines, calibration logic, communications, and field-update support. The 2 KB EEPROM can retain sensor offsets, calibration coefficients, serial numbers, and configuration values independently of the 4 KB SRAM working area. Use the four-channel event system to connect timer, comparator, or interrupt events so acquisition and control actions can begin without continuous polling.
Recomendado
Communication Gateway Controller
The ATXMEGA64C3-AN is appropriate for compact protocol bridges and communication gateways where local buffering and deterministic event handling are important. The 64 KB in-system programmable Flash provides room for multiple protocol stacks, boot code, and update routines, while the 8 KB boot-code section supports a distinct startup area. The 2 KB EEPROM is useful for retaining addresses, calibration, and operating parameters, and the 4 KB SRAM supports packet assembly. Hardware event routing can coordinate timer deadlines, receive events, and status changes with less software polling.
Recomendado
Compact Automation Controller
The ATXMEGA64C3-AN supports compact automation controllers that coordinate timers, digital inputs, outputs, and analog comparison functions in a low-power design. Its 32 MHz operating rate supports responsive control tasks, and the four-channel event system can link peripheral events for faster response than timer-only polling. Memory partitioning is practical for small embedded systems: firmware and boot code reside in Flash, retained settings use 2 KB EEPROM, and 4 KB SRAM accommodates the control state, diagnostics, and communication buffers. The 1.6 V to 3.6 V supply range also fits low-voltage industrial control boards.
Recomendado
Data Logger with Local Storage
The ATXMEGA64C3-AN is well matched to compact data loggers that timestamp samples, run local filtering, and maintain configuration data. Its 64 KB Flash provides substantially more code space than a 32 KB-class member, allowing storage algorithms, file handling, communications, and a bootloader to coexist. The 2 KB EEPROM is suitable for sequential counters, calibration values, and log metadata, while 4 KB SRAM supports sample buffering. The four-channel event system can synchronize acquisition with periodic timing events and external change signals, improving repeatability in compact instrumentation.
Recomendado
Low-Power Embedded Control
The ATXMEGA64C3-AN targets compact embedded-control products where low-voltage operation, local EEPROM, and peripheral integration are valuable. A 1.6 V to 3.6 V operating range allows the MCU to participate in 3.3 V power architectures while leaving 5 V interfaces to suitable level-shifting or transceiver components. Its 4 KB SRAM and 64 KB Flash cover moderate control workloads without an external memory bus, and EEPROM preserves settings across power cycles. Use peripheral sleep modes, clocks, and event routing to reduce processor activity when the system is waiting for external events.
Recomendado
Connected Control and Monitoring Node
The ATXMEGA64C3-AN can serve as the local controller in a connected industrial, building, or equipment-monitoring node. Its 64 KB Flash accommodates networking code and application logic, EEPROM retains node identity and calibration information, and SRAM supports message processing. The event system provides a hardware route for timer, comparator, and digital-change events, allowing the node to react promptly to alarms or state changes. The 64-pin TQFP provides access to multiple I/O functions, while the low-voltage operation suits isolated or power-constrained monitoring electronics when the surrounding signal chain is designed appropriately.

Notas de diseño
Allocate the 64-pin TQFP footprint according to the manufacturer land pattern and place decoupling capacitors close to the device power pins. Separate analog, digital, and switched return paths where the board architecture permits, and keep the external clock route short. The 1.6 V to 3.6 V operating range does not remove the need to verify voltage limits, startup sequencing, and supply-current behavior in the final power architecture.
Use the manufacturer pin-description table when assigning multiplexed I/O functions, programming signals, reset, clock, and peripheral connections. Check alternate peripheral locations against the final firmware plan before fixing the PCB netlist because moving a function to another pin can change routing, interrupt behavior, or board-level timing. Do not infer pin assignments from another ATxmega64C3 package or ordering suffix without checking the exact device table.
Do not assume that the -AN and -ANR suffixes represent different processor functions; confirm the ordering-code definitions before selecting a part. Also avoid replacing the 64 KB device with a 32 KB member solely because the package name appears similar. Firmware size, boot space, SRAM, EEPROM, peripheral assignment, voltage limits, and temperature requirements must all be reviewed before authorizing a substitution.
Estimate average and peak supply demand before fixing regulator capacity and copper dimensions. The device operates across 1.6 V to 3.6 V, so the usable current budget depends on the selected operating voltage and clock frequency. Include startup, peripheral activity, I/O loading, and worst-case environmental conditions in the estimate, then verify that the regulator, capacitors, and supply network remain within the manufacturer limits.
