ATXMEGA128B1-CU - 32MHz 128KB Flash MCU | Microchip
MPN: ATXMEGA128B1-CU ✓ AktifATXMEGA128B1-CU Ringkasan
An 8/16-bit microcontroller is a programmable semiconductor that combines a CPU core, nonvolatile program memory, working memory, peripheral interfaces, and general-purpose I/O in one package. The AVR XMEGA family extends the AVR architecture with hardware resources intended for control, communication, display, data acquisition, and real-time embedded applications. This places the ATXMEGA128B1-CU within the hierarchy of microcontroller, embedded processor, and semiconductor.
The 128 KB Flash program memory gives application code and constant data dedicated nonvolatile storage, while the separate 8 KB boot-code section supports protected startup routines. Its 8 KB SRAM accommodates working data, buffers, and interrupt or DMA-driven transfers, and the 2 KB EEPROM retains configuration values when the main supply is removed. The 32 MHz maximum operating frequency supports faster control-loop and peripheral operation.
Peripheral integration is a major technical advantage. The two-channel DMA controller can transfer data between peripherals and memory with reduced CPU intervention, while the four-channel event system routes events between timers, DMA channels, and other peripherals. A programmable multilevel interrupt controller manages prioritized event handling. According to the Microchip ATxmega128B1 product page, the device also includes a USB Full Speed device controller and an LCD controller supporting displays up to 4 x 40 segments.
Typical uses include USB-connected industrial controls, compact human-machine interfaces, instrumentation, display systems, and real-time embedded products. The USB interface supports direct connectivity to a host, while the large I/O count accommodates sensors, actuators, communication transceivers, and display elements. The integrated DMA and event system are particularly useful when deterministic timing must be maintained alongside USB or display activity.
PCB design should follow the manufacturer’s ball-map and layout guidance for the 100-ball package. Place decoupling capacitors at each supply ball as directed, route sensitive signals away from fast-switching nodes, and preserve the required ground-return paths. Confirm the exact ball assignments, exposed-pad arrangement, and reflow profile against the Microchip package documentation before releasing the PCB artwork.
This product reference combines the manufacturer’s device capabilities with package-specific selection guidance, practical interface considerations, and direct comparison against the identified same-package ordering variant. It is intended to accelerate engineering evaluation while keeping the final footprint, firmware, and lifecycle decisions tied to Microchip’s official documentation.

USB-connected industrial controller
The ATXMEGA128B1-CU fits USB-connected industrial controllers because it combines a USB Full Speed device interface with 128 KB of Flash and 8 KB of SRAM at a 32 MHz clock. The two-channel DMA controller can move data between USB and memory with less CPU intervention, while the four-channel event system helps coordinate timing-sensitive peripheral activity. Use it for configuration interfaces, data acquisition, actuator monitoring, and compact control panels that need local processing. Its 1.6 V to 3.6 V supply range also supports low-voltage embedded architectures, but the board must follow Microchip’s ball layout, decoupling, and USB routing guidance.

Human-machine display interface
The ATXMEGA128B1-CU is appropriate for human-machine interfaces because its integrated LCD controller supports displays up to 4 x 40 segments, while 53 GPIO lines provide connections for keys, indicators, and control signals. The 128 KB Flash can retain a local user interface, fonts, diagnostics, and communication logic, and 8 KB of SRAM supports display buffering. At 32 MHz, the device can service both display updates and event-driven control tasks. Designers should budget the limited LCD segment capacity and verify package ball assignments, contrast timing, and display voltage requirements against the manufacturer documentation.

Real-time sensor acquisition system
The ATXMEGA128B1-CU supports real-time sensor acquisition with its 32 MHz AVR core, two-channel DMA controller, programmable interrupt structure, and four-channel event system. DMA can transfer sampled data directly between a peripheral and SRAM, reducing CPU workload while the event system coordinates triggers among counters, communication interfaces, and control logic. The 8 KB SRAM is suitable for short acquisition buffers, while 128 KB of Flash holds acquisition code and calibration tables. Exact analog front-end performance depends on the selected sensors and external signal conditioning, and the final design must establish grounding and timing margins in accordance with the manufacturer’s guidance.
Disebarkan
USB data logger
The ATXMEGA128B1-CU can serve as the controller in a USB data logger that receives records through USB Full Speed and stores them in the 128 KB Flash program area or transfers them to a host. Its 8 KB SRAM provides working space for buffering, and the DMA controller can support transfers that do not require constant CPU servicing. The four-channel event system is useful for timestamp-related triggers, while the 2 KB EEPROM can retain compact configuration information. Firmware should define wear management, record buffering, and USB enumeration behavior, while the PCB should reserve a solid ground reference and follow the manufacturer’s USB signal-routing layout.
Disebarkan
Compact industrial instrument
The ATXMEGA128B1-CU suits compact instruments that combine measurement, local display, communication, and control in one 100-ball device. Its 53 GPIO lines can connect sensors, switches, status indicators, and communication devices without requiring a large external pin count. The LCD controller supports segmented local displays, while USB provides a service and data interface. At up to 32 MIPS and with 8 KB SRAM, the controller can execute acquisition, filtering, and user-interface routines, although application-specific timing should be verified through firmware analysis. Board construction must also account for the exact package geometry and ball map before committing to a 100-ball layout.
Disebarkan
Automated equipment control module
The ATXMEGA128B1-CU can act as the local control MCU in automated equipment where deterministic event handling, programmable I/O, and local USB service access are required. The event system can link counters, DMA requests, and interrupt events, while the DMA controller reduces processor involvement during data movement. Its 128 KB Flash and 8 KB boot-code section provide room for control logic, diagnostics, and protected startup behavior. The 53 GPIO lines can serve digital I/O, status, and inter-module signaling, but motor-drive and safety-critical isolation should remain outside the MCU domain. Validation should include worst-case interrupt latency, watchdog behavior, and firmware recovery procedures.

Catatan Desain
Confirm the exact 100-ball mechanical drawing before creating the PCB footprint. Product information identifies a 9 x 9 mm CBGA, while another technical listing describes a 7 x 7 mm VFBGA. Use the manufacturer pinout associated with the exact ordering code, place supply decoupling capacitors at the designated pins, and provide uninterrupted ground connections beneath signal routing.
Route USB D+ and D- as a controlled differential pair over a continuous reference plane, with no branch stubs or unnecessary layer transitions. Keep the interface away from switching power stages and high-slew-rate digital nets. Follow the recommended trace geometry and impedance from the Microchip hardware documentation, and validate the completed board for USB Full Speed timing and susceptibility.
Design the 1.6 V to 3.6 V supply rail so it remains within the MCU’s documented operating range under startup, idle, active, and USB-transmit states. Place the manufacturer-recommended bypass capacitance at the supply balls and minimize return-path impedance. Review the device’s typical and maximum current consumption under the intended clock configuration before selecting regulators or bulk capacitance.
Do not assume that every ATXMEGA128B1 ordering code is mechanically interchangeable. The CU and CUR suffixes differ in ordering presentation, and TQFP or reduced-Flash family members do not share the same land pattern. Check the package drawing, ball map, temperature grade, programming interface, and pin multiplexing in the manufacturer documentation before releasing a drop-in substitution.
Maklumat Kesediaan
No explicit compliance declarations are included in the product information. The industrial-temperature indication identifies the ordering code but does not by itself establish AEC-Q100 qualification.
