ATXMEGA64B3-AN - 32MHz 64KB USB MCU | Microchip | TQFP
MPN: ATXMEGA64B3-AN ✓ सक्रियATXMEGA64B3-AN अवलोकन
An 8/16-bit microcontroller is a programmable semiconductor that executes firmware, monitors inputs, and controls system peripherals. The AVR XMEGA B3 architecture combines a modified Harvard memory organization, self-programmable Flash, EEPROM, SRAM, hardware multipliers, and event-system peripherals in a single integrated circuit. It occupies the microcontroller category within embedded processing and is suitable for compact control systems that need more peripherals than a basic general-purpose microcontroller.
The ATXMEGA64B3-AN operates at up to 32 MHz and reaches up to 32 MIPS throughput. Its 64 KB self-programming Flash includes a 4 KB boot-code section, while 4 KB of SRAM and 2 KB of EEPROM support working data, parameter storage, and state retention. A two-channel DMA controller can move data with less processor intervention, and the four-channel event system can trigger actions directly between hardware peripherals.
Its integrated USB Full Speed Device controller enables USB connectivity without a separate interface controller. The four-times-25-segment LCD controller supports segmented human-machine interfaces without requiring an external display driver. These resources are useful when a compact product must combine local controls, data acquisition, communications, and real-time peripheral coordination.
Typical uses include utility metering, home automation, climate control, industrial control, sports equipment, medical devices, USB-connected products, power tools, and fire-alarm systems. For example, an energy meter can use the LCD controller for a local display, the event system for periodic measurement timing, the DMA channels for data movement, and USB for configuration or data transfer.
PCB design should preserve the pin assignments, power requirements, clock network, and USB routing specified by the Microchip manufacturer datasheet. Place decoupling capacitors close to the supply pins, provide clean grounding around the USB interface, and verify signal integrity before finalizing a high-speed or externally exposed design. The 64-TQFP footprint also requires adequate assembly clearance around all four sides.

सामान्य अनुप्रयोग
ATXMEGA64B3-AN के लिए उपयुक्त है 6 अनुप्रयोगs: Utility Metering, USB Connectivity, Home Automation, Climate Control, Industrial Control, Medical and Power Tools.
Utility Metering
The ATXMEGA64B3-AN fits utility meters that combine local measurement, a segmented display, event-based timing, and USB service connectivity. Its 32 MHz operating frequency and 32 MIPS throughput provide headroom for sensor conditioning, calibration logic, and communication handling, while 64 KB of self-programming Flash stores application code and a separate 4 KB boot section supports controlled firmware updates. The 4 x 25 segment LCD controller can drive a local meter display, and the two-channel DMA controller can move sampled data with reduced processor involvement. The industrial temperature grade also supports use in metering equipment outside consumer environments, subject to final environmental qualification.
अनुशंसित
USB Connectivity
The ATXMEGA64B3-AN is appropriate for compact USB-connected accessories because it combines a USB Full Speed Device controller with 64 KB of Flash, 4 KB of SRAM, and a 32 MHz core. Firmware can service USB requests while the event system coordinates timers and peripheral inputs, and DMA channels can accelerate transfers between memory and compatible peripherals. This integration avoids the need for a separate USB interface controller in suitable product architectures. Board implementation still requires careful USB signal routing, controlled impedance, correct supply decoupling, ESD protection, and firmware that follows the device's USB programming guidance.
अनुशंसित
Home Automation
ATXMEGA64B3-AN can serve as the central controller in a compact home-automation node that handles user inputs, sensor acquisition, local display feedback, and scheduled events. Its four-channel event system can connect timer, pin-change, and peripheral events without routing every action through a software polling loop. The 4 x 25 segment LCD controller supports a local status display, while 64 KB of Flash and 4 KB of SRAM provide resources for protocol handling and application state. The architecture is especially useful where USB commissioning, data logging, or configuration is needed without adding a separate communications controller.
अनुशंसित
Climate Control
The ATXMEGA64B3-AN is suitable for climate-control equipment that must evaluate sensors, drive outputs, coordinate timing, and present operating information locally. At up to 32 MIPS, the device can combine control logic, temperature sensing, fan or valve management, and communications within one microcontroller. The four-channel event system supports time-based and signal-based control sequencing, while the LCD controller can display measured values or operating states on a segmented panel. Its 64 KB Flash also permits more elaborate control algorithms and field-upgrade support than a very small general-purpose MCU, provided the final design respects the device's electrical and temperature limits.
अनुशंसित
Industrial Control
The ATXMEGA64B3-AN supports compact industrial-control modules requiring deterministic peripheral interaction, local controls, and USB connectivity. Its two-channel DMA controller offloads suitable data-transfer operations, and the four-channel event system can trigger actions from timers, pins, or other peripherals. The 36 general-purpose I/O lines support external sensors and actuators, while the LCD controller can reduce the need for a separate display driver in operator-facing equipment. For production deployment, validate power integrity, industrial temperature performance, EMC behavior, output isolation, and any safety requirements applicable to the final machine.
अनुशंसित
Medical and Power Tools
ATXMEGA64B3-AN can be evaluated for compact medical accessories and powered tools where local sensing, motor or load control, USB connectivity, and firmware update capability must coexist in one device. Its 32 MHz performance supports responsive control logic, while DMA and the event system reduce processor involvement in repeated data movement and peripheral events. The 64 KB Flash and 4 KB boot-code section support application firmware and controlled updates, and the 4 x 25 segment LCD controller supports local status displays. These applications remain use-case dependent because medical and tool products can impose specialized safety, EMC, environmental, and functional-validation requirements.

डिज़ाइन नोट्स
Place the device's supply decoupling capacitors directly beside the associated power and ground pins, following the capacitor values and placement guidance in the manufacturer datasheet. Keep the USB transceiver supply and digital supply return path tightly controlled, particularly when the board also contains switching converters or motor drivers. Confirm the exact ATXMEGA64B3-AN supply limits and decoupling network rather than transferring requirements from a related XMEGA ordering code.
Route the USB D+ and D- pair as a controlled-impedance differential pair with continuous reference-plane support, minimized stubs, and no unnecessary test pads that interrupt the pair. Keep the USB connector, protection components, and transceiver pins in a compact signal path. Apply the manufacturer reference layout for the 64-TQFP footprint, maintain assembly and solder-joint clearance, and route high-current or noisy switching paths away from sensitive USB and clock traces.
Assign crystal or external-clock circuitry only after checking the clock-source requirements in the manufacturer datasheet. Keep the clock path short, symmetrical where applicable, and isolated from USB, LCD, and switching-node traces. Confirm startup, clock-source selection, and fuse or configuration requirements for the exact -AN ordering option. Incorrect clock or programming assumptions can prevent firmware startup even when the memory and peripheral specifications are correctly implemented.
Do not substitute an ATXMEGA64B3 family member solely because it uses a 64-TQFP package. Verify the complete pin table, Flash and SRAM capacity, USB implementation, LCD segment count, DMA resources, event-system channels, supply range, clock architecture, and programming interface. Family suffixes may change packaging or ordering conditions, and changing peripherals can require firmware changes even when the land pattern appears compatible.
Use the event system and DMA channels deliberately rather than servicing every timer or data-transfer event through polling. Map periodic sampling and communication tasks to hardware events where the application permits, leaving processor time for control calculations. This does not remove the need to define latency, buffer ownership, and interrupt priorities, but it can produce more deterministic behavior than a software polling architecture in a 32 MHz control loop.
