LPC1768UKZ Descripción general
An ARM Cortex-M3 microcontroller is a 32-bit embedded processor designed around the ARM Cortex-M3 instruction set, combining deterministic interrupt handling, compact code execution, and extensive peripheral integration. In the product hierarchy, the LPC1768UKZ is a microcontroller MCU and embedded processor within the broader semiconductor category. Its 512 KB flash supports embedded firmware, while 64 KB of data memory supports working storage. NXP describes the LPC1768 family as a scalable mainstream solution for embedded applications requiring high integration and low power consumption at frequencies up to 100 MHz.
The principal differentiators are the combination of 100 MHz operation, 512 KB flash, Ethernet MAC, USB Device/Host/OTG, eight-channel DMA, and a broad peripheral set in one device. The 8-channel 12-bit ADC supports multiple analog inputs without requiring an external converter, while the 10-bit DAC provides an on-chip analog output for control or signal-generation tasks. Four UARTs, two CAN channels, three SSP/SPI interfaces, three I²C interfaces, and I²S reduce the need for external communication controllers. Motor-control PWM further supports actuator and power-control designs.
The supplied NXP product information confirms the LPC1768UK family identity, while distributor records identify LPC1768UKZ as the ordering variant associated with a 100-pin, 3.3 V device. Exact voltage ranges, pin assignments, current limits, package dimensions, temperature limits, and clock-tree details require confirmation in the manufacturer datasheet because those values are not fully included in the supplied search extracts. The LPC1768UKZ should therefore be selected against the complete datasheet and board-level requirements before release to production.
Typical applications include industrial Ethernet controllers, USB-connected embedded systems, CAN-based automation equipment, motor-control systems, data loggers, communications equipment, and multi-channel sensor acquisition systems. The combination of Ethernet, USB, CAN, high-speed serial interfaces, and analog conversion allows a compact design to consolidate several functions normally distributed across separate ICs. This is particularly useful for industrial controllers, building-automation equipment, test systems, and connected embedded products.
A critical design consideration is package and PCB verification. The LPC1768UKZ uses a high-pin-count BGA package according to distributor records, so escape routing, via-in-pad or fanout strategy, exposed-pad handling, assembly capability, and thermal performance must be confirmed before layout release. Software migration should also account for peripheral-instance names, clock configuration, pin multiplexing, startup code, and the exact Cortex-M memory map.
This page consolidates the verified NXP family specifications, distributor package identification, pricing references, and application guidance. It distinguishes confirmed facts from missing datasheet details and avoids treating search-snippet information as a complete electrical characterization. Engineers should use the manufacturer datasheet for final pinout, timing, power, EMC, and qualification decisions.

Aplicaciones típicas
LPC1768UKZ es adecuado para 8 aplicacións: Industrial Ethernet Control, CAN-Based Factory Automation, USB Connected Embedded System, Multi-Channel Sensor Acquisition, Motor Control and Power Conversion, Communications Gateway, Test and Measurement Instrument, Building Automation Controller.
Industrial Ethernet Control
The LPC1768UKZ fits industrial Ethernet controllers because its NXP LPC1768UK family specification combines a 100 MHz ARM Cortex-M3 core with integrated Ethernet MAC, 512 KB flash, and 64 KB data memory. The MCU can manage local control logic while an Ethernet interface supports supervisory communication, configuration, and telemetry. Place the MCU with the required PHY, magnetics, isolation, and protection components, then validate signal integrity against the Ethernet physical layer requirements. The high-pin-count BGA package also demands careful escape routing and thermal review, but it supports dense peripheral integration without adding a separate communications controller.
Recomendado
CAN-Based Factory Automation
The LPC1768UKZ is appropriate for CAN-based factory automation because the supplied NXP information lists two CAN channels, four UARTs, three SSP/SPI interfaces, and three I²C interfaces alongside the 100 MHz Cortex-M3 core. One design can coordinate actuators, read sensors, communicate with a human-machine interface, and retain diagnostics locally. External CAN transceivers, termination, protection, and isolation may be required depending on the bus environment. Firmware should validate bit timing, error handling, bus-off recovery, and peripheral clock configuration before connecting the controller to production equipment.
Recomendado
USB Connected Embedded System
The LPC1768UKZ can serve as the host controller in a USB-connected embedded product because the LPC1768UK family specification includes USB Device, Host, and OTG functionality. A practical implementation can use the MCU for local control while USB provides service access, data exchange, configuration, or peripheral connectivity. The exact USB transfer details and electrical implementation must be confirmed in the complete NXP datasheet. Layout should provide controlled-impedance USB routing, correct connector and protection components, adequate supply capacity, and a clean separation between sensitive analog or communications paths and high-current switching nodes.
Recomendado
Multi-Channel Sensor Acquisition
The LPC1768UKZ supports multi-channel sensor acquisition through its integrated 8-channel 12-bit ADC, 100 MHz processing core, and extensive serial interfaces. The ADC can sample multiple analog inputs while UART, SPI, and I²C interfaces connect external sensors, displays, or storage devices. The 10-bit DAC can provide a basic analog output for excitation or control testing, although its accuracy and dynamic behavior must be checked in the datasheet. Analog layout, reference quality, grounding, anti-aliasing, and calibration strategy are as important as the MCU selection for accurate measurements.
Recomendado
Motor Control and Power Conversion
The LPC1768UKZ is a functional match for motor-control and power-conversion control loops because the LPC1768UK family includes motor-control PWM, fast serial connectivity, ADC channels, and a 100 MHz ARM Cortex-M3 processor. The MCU can execute control algorithms, sample feedback signals, drive PWM outputs, and communicate with supervisory electronics. Power-stage components such as MOSFETs, gate drivers, current sensors, and protection circuits must be selected separately. Validate PWM timing, ADC synchronization, dead time, fault handling, thermal margins, and isolation requirements against the actual power stage before connecting a motor.
Recomendado
Communications Gateway
The LPC1768UKZ is useful for a communications gateway that must bridge several embedded interfaces. Its listed peripherals include Ethernet MAC, USB, four UARTs, two CAN channels, three SSP/SPI interfaces, three I²C interfaces, I²S, and an 8-channel DMA controller. This allows one device to collect data from sensors or instruments and forward it through multiple system interfaces. Protocol implementation, buffer sizing, interrupt latency, and DMA ownership should be planned together. Because the package is a 100-pin BGA according to distributor records, signal-integrity and assembly planning must begin before schematic capture is finalized.
Recomendado
Test and Measurement Instrument
The LPC1768UKZ can support a compact test or measurement instrument that combines acquisition, control, communications, and data storage. The 8-channel 12-bit ADC provides analog measurement capability, the 10-bit DAC supports basic stimulus generation, and the 100 MHz Cortex-M3 core can run control and communication firmware. UART, SPI, I²C, USB, and Ethernet options allow the instrument to connect to a host, display, storage module, or automation controller. For high-precision measurements, retain the ADC and DAC for general-purpose functions but verify accuracy, reference stability, noise, calibration, and input bandwidth against the complete datasheet.
Recomendado
Building Automation Controller
The LPC1768UKZ fits building-automation controllers that coordinate sensors, actuators, communications, and local control logic. Ethernet and CAN provide options for wired building networks, while USB and serial interfaces support commissioning and local maintenance. The 100 MHz Cortex-M3 core and 512 KB flash provide room for protocol stacks and application firmware, while the integrated ADC can monitor environmental or equipment conditions. Deployment decisions should account for isolated transceivers, surge protection, EMC requirements, watchdog behavior, low-power modes, and long-term component availability. Verify the exact operating-temperature and environmental requirements before installation.

Notas de diseño
Treat the LPC1768UKZ as a BGA-layout problem. Confirm the official ball map, ball pitch, package height, exposed-pad arrangement, and assembly process before committing to a footprint. Design controlled escape routing, adequate via structures, solder-mask and paste controls, and a thermal path using the manufacturer package drawing. Do not rely on distributor package descriptions alone for production artwork.
Build the power tree around the complete NXP electrical specification, not the 3.3 V shorthand found in distributor listings. Verify supply tolerances, core and I/O current, regulator headroom, startup current, brownout behavior, and current required by Ethernet magnetics, transceivers, USB, and external actuators. Add local bulk and high-frequency decoupling according to the datasheet and validate the rail with representative load transients.
Ethernet, USB, I²S, and high-speed SSP/SPI paths require disciplined return paths and controlled topology. Confirm impedance, trace lengths, via transitions, series-termination requirements, and connector placement from the applicable NXP interface guidance. Keep switching power loops and motor-drive currents away from analog inputs and communication lines, and use the MCU ground and power references shown in the recommended layout.
The LPC1768UKZ integrates high-speed processing and multiple communications peripherals, so package temperature and adjacent power components must be evaluated under worst-case activity. Use the manufacturer’s thermal data when available and estimate junction rise only with clearly stated assumptions. Check BGA solder-joint reliability, exposed-pad or thermal-via implementation, enclosure temperature, and copper spreading for sustained industrial operation.
A family-compatible marking does not prove that an alternate ordering code is a drop-in replacement. Confirm the exact LPC1768UKZ package suffix, ballout, flash configuration, pin multiplexing, clocking, and lifecycle status. For firmware migration, compare startup files, linker memory assumptions, peripheral names, interrupt vectors, register differences, and vendor SDK support before production deployment.
Información de cumplimiento
The supplied search results identify NXP as the manufacturer and describe a 3.3 V 100-pin device, but they do not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. Confirm these attributes from the current NXP product documentation before release.
