N.º da peça: LPC11U68JBD64K ✓ AtivoLPC11U68JBD64K Visão geral
A microcontroller is a semiconductor integrated circuit that combines a processor core, program memory, data memory, and peripherals on one die. In the product hierarchy, the LPC11U68JBD64K is an embedded microcontroller, then a 32-bit microcontroller, and ultimately a general-purpose semiconductor. The Arm Cortex-M0+ architecture is designed for compact embedded-control code, while the presence of Cortex-M0-compatible family information supports simple control-oriented product designs.
The principal verified characteristics are a maximum CPU frequency of 50 MHz, 256 KB of flash, a 32-bit CPU, Arm Cortex-M0+/M0 family architecture, and a 64-LQFP surface-mount package. The NXP product page identifies LPC11U68JBD64 as active. This combination makes the LPC11U68JBD64K relevant to embedded control, IoT device, industrial automation, motor-control, metering, and low-power board applications where a compact 32-bit control platform is required.
The LPC11Uxx family is intended to replace conventional 8-bit and 16-bit microcontroller implementations with a more capable 32-bit architecture. Its operating frequency of up to 50 MHz provides additional processing headroom for protocol handling, control logic, and state management, while the simple Arm instruction set can reduce software complexity compared with more elaborate embedded processor architectures. Exact RAM, peripheral, voltage, and timing details must be confirmed in the manufacturer datasheet before schematic or firmware design begins.
Typical application opportunities include smart metering, connected sensors, compact industrial controllers, motor-control supervisory logic, appliance controls, and low-power IoT nodes. In these systems, the 256 KB flash capacity accommodates a bootloader, application firmware, configuration data, and protocol code. The 10 mm by 10 mm LQFP package also supports conventional surface-mount assembly while providing more exposed perimeter pins than a small leadless package.
Designers should use the official NXP data sheet as the controlling source for pin assignment, power requirements, clocking, peripherals, programming, and package dimensions. The LPC11U68JBD64K is supported by the NXP LPC11U00 CMSIS device family package, providing a defined software-device and peripheral baseline for embedded toolchains.
This product page consolidates verified manufacturer and distributor information, pricing availability, package details, datasheet links, application context, and design cautions. It also distinguishes confirmed specifications from unavailable data rather than estimating missing electrical or pin-level values, helping engineers make a safer sourcing and design decision.

Aplicações típicas
LPC11U68JBD64K é adequado para 6 aplicaçãos: Industrial Automation Controller, IoT Sensor Node, Smart Metering, Motor-Control Supervisory Logic, Low-Power Board Controller, Connected Appliance Controller.
Industrial Automation Controller
The LPC11U68JBD64K fits compact industrial-control logic where a 32-bit Arm Cortex-M0+/M0-class processor is useful without moving to a more complex microcontroller platform. Its verified 50 MHz maximum operating frequency provides processing headroom for sequencing, state-machine execution, and communication handling, while 256 KB of flash can hold application code, configuration, and a bootloader. The 64-LQFP package measures 10 mm by 10 mm and exposes substantially more perimeter connections than a compact leadless package, which can simplify assignment of control and communication signals. Before final schematic release, verify the required GPIO count, supply voltage, analog functions, communication peripherals, and timing limits in the NXP datasheet.
IoT Sensor Node
The LPC11U68JBD64K can serve as the control processor in a compact IoT sensor node because it combines a 32-bit Cortex-M0+/M0-class architecture, up to 50 MHz operating speed, and 256 KB of flash in a standard surface-mount LQFP package. The available flash can accommodate a networking stack, sensor-processing logic, device configuration, and firmware update capability, subject to the final firmware size and boot requirements. The LPC11U00 CMSIS device package provides a recognized software baseline for embedded development. Actual suitability depends on the node's required serial interfaces, RAM budget, low-power modes, wake-up behavior, and supply characteristics, which were not present in the verified excerpts.
Smart Metering
The LPC11U68JBD64K is relevant to smart-metering designs that are migrating from 8-bit or 16-bit controllers while retaining a compact 10 mm by 10 mm LQFP footprint. The 32-bit processor and 50 MHz operating ceiling offer more headroom for measurement sequencing, data filtering, calibration logic, communications formatting, and secure data handling than a basic low-end controller may provide. Its 256 KB of flash supports dedicated application firmware, meter parameters, and a bootloader within one device. Metering designers should confirm the required measurement interfaces, timers, communication peripherals, RAM, and accuracy-related peripherals in the official manufacturer documentation before schematic release.
Motor-Control Supervisory Logic
The LPC11U68JBD64K can be used for supervisory and coordination logic around a motor-control system rather than as an unqualified substitute for a dedicated motor driver. Its 50 MHz Arm Cortex-M0+/M0-class core and 256 KB flash provide capacity for position sequencing, fault handling, communication protocols, and machine-state logic. The 64-LQFP package offers 64 available package positions for control and interface routing, although the exact multifunction pin assignments must be read from the datasheet. A production design must verify timer architecture, capture/compare resources, analog channels, operating voltage, and any timing-critical motor-control requirements before assigning the MCU to a safety-related function.
Low-Power Board Controller
The LPC11U68JBD64K suits a low-power board controller that needs more capability than a basic 8-bit device but does not require a large high-end MCU. The verified 32-bit architecture, 50 MHz maximum frequency, and 256 KB flash provide room for local control logic, diagnostics, communication handling, and configuration storage. Its surface-mount 64-LQFP format is compatible with standard PCB assembly processes and offers ample package pins for interfaces. Power-sensitive designs must confirm the family's detailed sleep-mode currents, active current, clock tree, and wake-up sources in the manufacturer datasheet, because those figures were not included in the supplied source excerpts.
Connected Appliance Controller
The LPC11U68JBD64K is applicable to compact appliance controllers that coordinate user inputs, sensors, relays, displays, and communications. A 50 MHz Cortex-M0+/M0-class processor can execute a real-time control state machine and support protocol handling, while 256 KB of flash provides storage for application firmware and configuration. The 10 mm by 10 mm 64-LQFP package simplifies assembly and exposes enough package positions for mixed digital and communication functions. Designers should verify the exact UART, SPI, I2C, timer, and GPIO resources required by the appliance platform, along with supply range and environmental constraints, before treating the device as a production-ready match.

Notas de projeto
Do not begin PCB routing from generic 64-LQFP assumptions. The verified package is 64-LQFP at 10 mm by 10 mm, but the supplied excerpts do not provide individual pin names, exposed-pad details, or a land pattern. Obtain the official NXP package drawing and complete pin table, then verify every power, ground, reset, clock, programming, and peripheral connection against the intended LPC11U68JBD64K variant.
Plan the PCB for surface-mount assembly of the 10 mm by 10 mm 64-LQFP package. Maintain copper symmetry, follow the manufacturer's solder-mask and paste-land dimensions, and place decoupling structures directly at the device's confirmed power pins. Because the exact power-pin arrangement is not present in the supplied data, do not infer it from similar LPC11Uxx devices.
The supplied evidence confirms processor speed, flash capacity, package size, and family architecture but does not provide operating voltage or supply-current limits. Before powering a prototype, confirm the power architecture, decoupling requirements, internal regulator usage, brownout behavior, and I/O voltage limits in the manufacturer datasheet. These checks are especially important when the board also supports communication peripherals or sensors.
Reserve space for programming and debug access, clock components, decoupling, and any required pull devices even though the exact pin map was not supplied. Keep sensitive analog or communication routes away from noisy switching nodes and follow the manufacturer's guidance for exposed-pad grounding if the selected package drawing specifies one. Firmware bring-up should begin with conservative clocks and unused peripherals disabled.
Informações de conformidade
The verified excerpts identify the manufacturer, active lifecycle status, package, processor, memory, and market availability but do not provide compliance declarations. AEC-Q100 qualification is recorded as unknown rather than not_applicable because the excerpt does not state the device's automotive qualification status.
