LPC11U67JBD64E - 50MHz Cortex-M0+ 128KB MCU | NXP
N.º da peça: LPC11U67JBD64E ✓ AtivoLPC11U67JBD64E Visão geral
A microcontroller is a semiconductor that integrates a CPU core, memory, peripherals, and communication interfaces into one device. The ARM Cortex-M0+ core provides a compact, energy-efficient architecture for embedded control, while the LPC11Uxx family sits within the broader hierarchy of microcontroller, embedded processor, and semiconductor products. Its 50 MHz operating frequency supports responsive control loops and communication handling without requiring a high-end application processor.
The verified device data identifies a 32-bit ARM Cortex-M0+ processor, 128 KB (128K x 8) flash, and a 64-LQFP (10 x 10 mm) package. The E suffix is retained as part of the exact orderable MPN. NXP describes the family as scalable and entry-level, indicating suitability for designs that need broad peripheral integration while controlling system complexity, board area, and cost.
Compared with larger Cortex-M microcontrollers, the LPC11U67JBD64E provides a focused 50 MHz Cortex-M0+ platform with 128 KB of embedded flash in a 10 mm square LQFP. The 64-pin package offers more external interface options than smaller lead-count packages, making it useful when a design requires both USB connectivity and additional I/O. Exact SRAM capacity, voltage range, peripheral inventory, and electrical limits require confirmation in the manufacturer datasheet.
Typical applications include USB-connected control devices, USB-to-serial adapters, human-interface-interface controllers, compact industrial controllers, instrument-panel controllers, and embedded USB peripherals. The 64-pin package can support a mix of communication, logic, and discrete I/O, while the Cortex-M0+ core handles protocol stacks, sampling, and supervisory tasks in a single device.
Designers should verify the exact pin assignments, USB electrical requirements, decoupling network, clock configuration, and exposed programming/debug interfaces against the manufacturer datasheet before layout release. PCB traces, connectors, and protection components must be designed for the device's USB and power specifications. Because no complete public pinout was included in the supplied verified data, no pin-level substitutions should be inferred from this page.
This product record combines exact distributor pricing and availability information, same-package family comparisons, and practical engineering guidance. It distinguishes verified facts from parameters that still require datasheet confirmation, helping engineers source the exact LPC11U67JBD64E without confusing a related LPC11E-series device with a guaranteed drop-in replacement.

Aplicações típicas
LPC11U67JBD64E é adequado para 6 aplicaçãos: USB-to-Serial Adapter, Human Interface Device Controller, Embedded USB Data Acquisition Controller, USB Communications Gateway, Compact Industrial Control Module, Programmable USB Test Fixture.
USB-to-Serial Adapter
The LPC11U67JBD64E fits a compact USB-to-serial adapter because its 50 MHz ARM Cortex-M0+ core can service USB traffic and serial conversion while the 128 KB of flash provides room for the USB stack, command processing, and configuration logic. The 64-LQFP package also offers more I/O than a small lead-count controller, which can simplify connection of status indicators, control signals, or flow-control lines. A practical design would implement the supported USB device role in firmware and use the LQFP footprint to separate USB data routing from the serial transceiver. Before layout, verify the exact USB pins, operating-voltage range, crystal requirements, and transceiver or transceiver-less architecture in the NXP datasheet.
Recomendado
Human Interface Device Controller
The LPC11U67JBD64E is appropriate for a keyboard, mouse, control-panel, or other USB HID controller because its 50 MHz Cortex-M0+ core can execute the device firmware and USB protocol handling concurrently with debouncing and report generation. With 128 KB of flash, the design can retain boot code, HID descriptors, configuration data, and application logic in one microcontroller. The 64-LQFP package provides a practical number of I/O pins for switches, indicators, and sensors. Use careful debounce design and validate USB signal routing, bus-powered current behavior, and enumeration timing. Exact peripheral assignments and USB electrical requirements must be confirmed before the footprint is released.
Recomendado
Embedded USB Data Acquisition Controller
The LPC11U67JBD64E can serve as a compact USB data-acquisition controller when the acquisition task fits its 50 MHz ARM Cortex-M0+ core and 128 KB of flash. The processor can coordinate sensor sampling, buffer results, expose a USB interface, and provide local control signals through its 64-lead LQFP package. This arrangement is useful for laboratory modules, condition-monitoring nodes, and portable instrumentation where USB provides both power context and a data path. Engineer the firmware around deterministic sampling and buffering, and confirm available SRAM before defining record sizes. The supplied data does not specify ADC channels, DAC channels, or timer resources, so analog front-end selection should follow the full manufacturer peripheral table.
Recomendado
USB Communications Gateway
The LPC11U67JBD64E is a viable controller for a small USB communications gateway because its Cortex-M0+ core provides a 50 MHz processing platform and its 128 KB of flash can hold protocol conversion, buffering, and management firmware. The 64-LQFP package gives the designer access to more I/O than a compact 20-pin MCU, which can accommodate configuration inputs, status outputs, and a non-USB serial or network interface. A practical implementation would isolate the USB routing from any external communications line and use deterministic buffering for variable-rate traffic. Verify supported USB modes, endpoint count, RAM availability, and pin multiplexing in the datasheet before fixing the architecture. For gateway products, add ESD protection and controlled impedance on the USB interface.
Recomendado
Compact Industrial Control Module
The LPC11U67JBD64E can be used in a compact industrial control module when its 50 MHz processing rate, 128 KB flash capacity, and 64-LQFP footprint satisfy the application. The microcontroller can manage discrete inputs, relay or actuator control signals, status feedback, and a USB configuration interface in one package. The family positioning as a scalable entry-level MCU supports cost-sensitive embedded designs that need more capability than a simple state machine but do not require a higher-performance Cortex-M core. Industrial suitability must be established from the datasheet's temperature range, supply limits, ESD data, and qualification statements. Production layouts should provide local decoupling, robust return paths, and appropriate protection between field wiring and the MCU.
Recomendado
Programmable USB Test Fixture
The LPC11U67JBD64E is well suited to a programmable USB test fixture used for configuration, interface verification, or automated test. Its 50 MHz ARM Cortex-M0+ core can execute test sequences while the 128 KB of flash stores firmware and test definitions. The 64-LQFP package provides enough external signals to coordinate fixtures, observe results, and drive multiple peripheral functions. Engineers can use USB for command exchange while dedicated I/O controls the device under test. Before implementation, confirm the supported USB role, endpoint configuration, clocking method, and available timers in the manufacturer documentation. A practical fixture also needs deterministic reset control, input protection, and defined connector pinouts to avoid using undocumented package functions.

Notas de projeto
Use the official NXP 64-LQFP land pattern and pin table rather than deriving the footprint from the package dimensions alone. Keep USB data and power routing away from unrelated switching or high-current paths, provide the decoupling values required by the datasheet directly at the supply pins, and maintain continuous ground references beneath the device. Because the supplied data does not identify individual pins, do not assign USB, clock, reset, programming, or debug nets until the current manufacturer package drawing has been checked.
A matching package and identical 50 MHz CPU frequency do not by themselves establish a drop-in substitution. Before replacing LPC11U67JBD64E with an LPC11U68 or LPC11E68 device, compare every power pin, ground pin, USB signal, oscillator connection, debug interface, peripheral mapping, interrupt vector, boot configuration, and flash/RAM requirement. The verified comparison shows that LPC11E68JBD64E has 256 KB of flash versus 128 KB for the target, so firmware placement and startup code may also need review.
Confirm the device's supported supply range, absolute maximum ratings, power-consumption modes, and USB bus-current requirements in the manufacturer datasheet before selecting capacitors or protection components. Place the required input capacitance close to the relevant power pins and account for USB attachment or disconnect transients. Do not use the family-level 50 MHz frequency as a proxy for current consumption; calculate worst-case load from verified operating-mode data and application-specific USB configuration.
Preserve short, controlled-impedance USB routing and provide the ESD and impedance components specified by NXP for the selected USB architecture. Keep crystal or clock circuitry compact and away from USB and switching nodes, and maintain predictable return paths beneath high-speed signals. Firmware developers should also verify clock startup, USB clocking, and low-power transitions. The same care applies to debug and programming access so production programming does not require board rework.
Informações de conformidade
The supplied verified search results do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These attributes must be confirmed from the current NXP product documentation or supplier declaration.
