Teilenummer: LPC1766FBD100K ✓ AktivLPC1766FBD100K Übersicht
An ARM Cortex-M3 microcontroller is a 32-bit reduced-instruction-set processor designed for embedded control. The Cortex-M3 core uses the Thumb-2 instruction set and provides deterministic interrupt handling, while integrated flash, SRAM, peripherals, and communication interfaces reduce system complexity. The LPC1766 belongs to the NXP LPC17xx microcontroller family, combining an ARM processor core with Ethernet, USB, CAN, serial, analog, and timer resources.
The LPC1766FBD100K provides 256 KB of flash memory and 64 KB of data memory for code and working data. Its integrated Ethernet MAC supports network-connected equipment, while USB Device, Host, and OTG operation supports peripheral connectivity, USB storage, and host applications. The device also includes an 8-channel DMA controller, four UARTs, two CAN channels, three SSP/SPI interfaces, three I2C interfaces, I2S support, an 8-channel 12-bit ADC, a 10-bit DAC, and motor-control PWM resources.
The 100 MHz Cortex-M3 core provides a practical balance of processing performance, memory capacity, and peripheral integration. It is suited to applications requiring multiple communication protocols, mixed analog and digital functions, or deterministic control without requiring a separate Ethernet controller, USB interface, or analog conversion system. The eight-channel ADC and motor-control PWM blocks are particularly useful in monitoring and actuator-control designs.
Typical uses include industrial Ethernet gateways, USB-to-serial data loggers, CAN-based industrial controllers, networked measurement equipment, motor-control systems, audio equipment using I2S, and connected consumer products. The LQFP-100 package provides exposed component leads and works with conventional reflow and inspection processes, while its 100-pin count supports the large number of communications and control functions.
Designers should use the manufacturer datasheet and pin-description tables when assigning PCB tracks, configuring peripheral multiplexing, and selecting decoupling. Verify the operating voltage, clock configuration, Ethernet PHY integration, USB transceiver requirements, and unused-pin treatment against the device documentation before releasing a layout. The LQFP-100 footprint also requires adequate thermal copper and assembly clearance because of its relatively large lead frame.

Typische Anwendungen
LPC1766FBD100K ist geeignet für 6 Anwendungs: Industrial Ethernet Gateway, USB Data Logger, CAN-Based Industrial Controller, Precision Measurement Instrument, Motor Control and Monitoring, Networked Audio and I2S Equipment.
Industrial Ethernet Gateway
The LPC1766FBD100K fits industrial Ethernet gateways because its 100 MHz Cortex-M3 core can supervise protocols while the integrated Ethernet MAC handles network traffic. Its 256 KB of flash supports gateway firmware, while 64 KB of SRAM accommodates protocol state and packet buffering. Four UARTs, two CAN channels, three I2C interfaces, and three SSP/SPI interfaces provide local sensor and actuator connectivity. The LQFP-100 package also exposes the required communications and control pins without requiring a very large board.
Empfohlen
USB Data Logger
The LPC1766FBD100K is appropriate for a USB data logger because it supports USB Device, Host, and OTG alongside four UARTs and an eight-channel 12-bit ADC. The 100 MHz core can format collected measurements, while DMA helps move data efficiently between memory and peripherals. Its 256 KB flash stores application firmware and calibration tables, and 64 KB of SRAM supports temporary acquisition buffers. External memory can be added when long-term storage requirements exceed the internal resources.
Empfohlen
CAN-Based Industrial Controller
The LPC1766FBD100K supports CAN-based industrial control with two CAN channels, three I2C interfaces, three SSP/SPI interfaces, and motor-control PWM. The 100 MHz Cortex-M3 core provides computational capacity for control logic, and the eight-channel 12-bit ADC supports analog feedback from sensors or power stages. An external CAN transceiver is still required for physical-layer communication, but the MCU integrates the protocol interface and firmware-facing peripherals in one package.
Empfohlen
Precision Measurement Instrument
The LPC1766FBD100K suits precision measurement instruments that combine analog acquisition with network or serial data transfer. Its eight-channel 12-bit ADC supports multi-channel sensor measurement, while the 10-bit DAC can provide a basic control or reference output. Four UARTs and three SSP/SPI interfaces connect displays, storage devices, and precision converters, while the Ethernet MAC and USB OTG capability support configuration and data export. The 100 MHz core performs filtering and calibration without requiring a separate DSP.
Empfohlen
Motor Control and Monitoring
The LPC1766FBD100K fits motor-control and monitoring designs because it combines motor-control PWM, an eight-channel 12-bit ADC, DMA, and a 100 MHz Cortex-M3 core. PWM outputs can command motor drivers or power stages, while ADC channels can monitor current, position, temperature, or supply feedback. Two CAN channels support distributed control, and the Ethernet MAC enables diagnostics to a supervisory system. The external power stage and isolation strategy remain application-specific design choices.
Empfohlen
Networked Audio and I2S Equipment
The LPC1766FBD100K can support networked audio equipment because it integrates I2S, Ethernet MAC, USB Device or Host, and multiple serial interfaces. The 100 MHz Cortex-M3 core can manage control traffic and audio configuration, while 64 KB of SRAM supports short audio frames, protocol buffers, and control state. USB and Ethernet provide separate paths for local computer connectivity and network control. Audio-clock routing and peripheral multiplexing should be checked against the device pin table before layout approval.

Designhinweise
Use the manufacturer pin-description table to assign the 100-LQFP footprint and verify every multiplexed peripheral signal. Place decoupling capacitors close to the supply pins, provide adequate ground-plane continuity, and route high-speed clock and communication lines away from analog inputs. Confirm the exposed or non-exposed thermal-pad arrangement, solder mask, and copper recommendations for the exact package drawing.
Plan the power tree around the LPC1766's supply and I/O voltage requirements, including startup current and any Ethernet, USB, or external transceiver loads. Use the manufacturer's recommended supply sequencing and decoupling configuration rather than treating the digital core, analog circuits, and I/O rails as one unrestricted rail. Verify voltage tolerance, ground references, and analog input limits against the datasheet before connecting external modules.
Keep the 100 MHz clock route short and controlled, follow the recommended source and load topology, and provide solid return paths beneath high-speed signals. Ethernet and USB interfaces are sensitive to reference-plane discontinuities and noisy return currents; keep their physical-layer support components close to the controller or transceiver where the application architecture requires it. Perform signal-integrity and EMC checks after the final stack-up is selected.
Do not assume that a similarly named LPC1766 orderable code is electrically and logistically identical. The LPC1766FBD100,551 is documented as the same device in a different packing format, while LPC1768FBD100K increases flash from 256 KB to 512 KB. Confirm the exact suffix, package, memory configuration, startup behavior, and production packing requirements before substitution or redesign.
