LPC1767FBD100K - 100MHz Cortex-M3 512KB MCU | NXP
N.º da peça: LPC1767FBD100K ✓ AtivoLPC1767FBD100K Visão geral
A microcontroller is a semiconductor integrated circuit dedicated to embedded control. Its hierarchy extends from an embedded processor to a microcontroller, an ARM Cortex-M3 core, and finally a general-purpose microcontroller with integrated flash, SRAM, analog converters, and communication peripherals. The LPC1767 therefore combines general-purpose firmware execution with multiple peripheral engines that reduce the need for separate interface components in connected embedded equipment.
The LPC1767 family is positioned for embedded applications requiring high integration and low power consumption. Its 100 MHz Cortex-M3 processor provides substantially more arithmetic capability than an 8- or 16-bit control MCU while retaining the deterministic peripheral architecture useful for communications, data acquisition, and motor-control systems. The 512 KB program memory supports a larger embedded code base than devices with only tens or hundreds of kilobytes of flash, while 64 KB of SRAM accommodates working buffers and protocol stacks.
Communication capability is a major feature. The integrated Ethernet MAC supports networked embedded designs, while the four UARTs, three SSP/SPI interfaces, three I2C interfaces, and I2S interface cover serial links to sensors, converters, storage, displays, and audio devices. The eight-channel 12-bit ADC and 10-bit DAC support analog measurement and signal generation. An eight-channel DMA controller can transfer data between peripherals and memory, reducing CPU involvement in data movement.
Typical LPC1767 applications include industrial Ethernet equipment, data acquisition modules, building-control gateways, communications equipment, motor controllers, and embedded test systems. It is particularly useful when several serial interfaces and analog channels must coexist on one controller. The 100-LQFP package exposes the extensive pin set but requires a substantially larger PCB footprint than a small-outline package.
For a new PCB, preserve the LPC1767FBD100K footprint and verify every Ethernet, analog, power, and boot-strapping connection against the manufacturer pinout. Do not treat a related LPC17xx device as an automatic replacement because memory size, CAN availability, peripheral options, or pin multiplexing may differ. For an assembled board, verify the exact suffix, Ethernet implementation, power rails, crystal circuit, and boot configuration before sourcing a replacement.

Aplicações típicas
LPC1767FBD100K é adequado para 6 aplicaçãos: Industrial Ethernet Gateways, Industrial Data Acquisition, Motor Control and Encoders, Communications Equipment, Building and Environmental Control, Audio and Digital Interface Control.
Industrial Ethernet Gateways
The LPC1767FBD100K fits industrial Ethernet gateways because its 100 MHz Cortex-M3 core can process protocol traffic while the integrated Ethernet MAC handles network connectivity without requiring a separate interface controller. Its 512 KB of flash and 64 KB of SRAM provide space for firmware, configuration data, and communication buffers. Four UARTs, three SSP/SPI interfaces, and three I2C interfaces allow local sensor, transceiver, and service-port connections. Unlike a basic 8-bit controller, this MCU combines networking and multiple serial peripherals in one 100-LQFP device. Industrial qualification still requires confirming the required temperature range, EMC performance, Ethernet magnetics, isolation, and long-term supply for the exact suffix.
Recomendado
Industrial Data Acquisition
The LPC1767FBD100K supports multi-channel data-acquisition systems by combining an eight-channel 12-bit ADC with eight-channel DMA and a 100 MHz Cortex-M3 processor. The ADC provides measured resolution for pressure, temperature, potentiometer, and process-control signals, while DMA can move samples between the converter and memory with less CPU intervention. Three I2C and three SSP/SPI interfaces can connect sensors, external converters, and memory. The 64 KB SRAM and 512 KB flash support buffering and application firmware. A practical design must still verify ADC reference accuracy, input impedance, sample-and-hold requirements, anti-aliasing filters, channel multiplexing, and the exact electrical limits in the manufacturer datasheet.
Recomendado
Motor Control and Encoders
The LPC1767FBD100K is well suited to motor-oriented embedded control because it includes motor-control PWM, a quadrature encoder interface, an eight-channel 12-bit ADC, and an eight-channel DMA controller. The PWM outputs can command motor drivers, while the quadrature encoder interface can track rotational position. ADC channels can monitor current, temperature, or analog feedback, and DMA can support periodic data movement. The 100 MHz Cortex-M3 core has greater performance headroom than entry-level 8-bit controllers for coordinated control loops. The MCU does not replace a power stage: designers still need a suitable gate driver or H-bridge, current sensing, protection, grounding, and timing checks against the exact NXP datasheet.
Recomendado
Communications Equipment
The LPC1767FBD100K provides a broad serial-interface set for communications equipment: four UARTs, three SSP/SPI interfaces, three I2C interfaces, I2S, Ethernet MAC, and eight-channel DMA. This allows a single microcontroller to supervise multiple protocol links while leaving hardware DMA for high-throughput transfers. Its 512 KB flash accommodates protocol stacks, configuration tables, diagnostics, and boot code, while 64 KB of SRAM supports active frames and queue management. The device is particularly attractive for compact embedded network terminals rather than high-volume consumer products. Final design work must verify baud-rate support, buffer limits, DMA channel allocation, Ethernet clock requirements, and the availability of suitable PHY and magnetics components.
Recomendado
Building and Environmental Control
The LPC1767FBD100K can serve as the controller in a building-control or environmental monitoring unit that combines network access, analog sensing, and serial peripherals. The eight-channel 12-bit ADC can acquire temperature, light, pressure, occupancy, or analog control feedback, while I2C suits sensors with addressable registers and SPI suits higher-speed sensors or display controllers. The integrated Ethernet MAC enables centralized reporting, and four UARTs provide local service or legacy-device connections. A 10-bit DAC can generate a basic analog control or test signal when appropriate filtering is added. Because the same MCU also targets low-power embedded systems, power-mode behavior and wakeup sources matter; consult the exact manufacturer documentation for clock, sleep, and I/O retention details.
Recomendado
Audio and Digital Interface Control
The LPC1767FBD100K can control audio-adjacent embedded functions because it provides three SSP/SPI interfaces, I2S support, a 10-bit DAC, and an eight-channel 12-bit ADC. A system can use I2S for digital audio transport, SPI for codecs or converters, and the DAC for control or test signals. The 100 MHz Cortex-M3 core can manage buffering and control functions, and eight-channel DMA reduces the processing burden of continuous transfers. Its 512 KB of flash is useful for substantial protocol and control firmware. The MCU is not a dedicated audio codec, so clock accuracy, data format, impedance, grounding, and analog signal integrity remain design tasks. Validate the required I2S mode and supported pin multiplexing against the manufacturer datasheet.

Notas de projeto
Use the exact NXP 100-LQFP land pattern and verify pin 1 orientation before placement. The supplied sources identify a 14 x 14 mm package but do not provide the complete pin table, so do not infer analog, Ethernet, clock, or boot connections from an adjacent LPC17xx design. Confirm every alternate-function assignment in the manufacturer datasheet, maintain a continuous ground reference, and place required decoupling capacitors at the associated supply pins according to the official recommended layout.
Treat the Ethernet interface as a controlled-impedance subsystem rather than ordinary digital routing. The MCU includes an Ethernet MAC, but the external PHY, isolation barrier, magnetics, protection components, and board stack-up determine signal integrity. Follow the NXP reference design when available, keep the Ethernet differential pair free of stubs and test pads, provide a continuous reference plane, and verify differential impedance and isolation requirements with the selected PHY implementation.
Separate analog and digital return paths carefully because the LPC1767FBD100K combines a 12-bit ADC, 10-bit DAC, Ethernet MAC, and high-speed digital interfaces. Use a low-impedance ground architecture, keep sensitive analog traces away from switching nodes and high-current return paths, and verify the ADC and DAC reference requirements in the manufacturer datasheet. The supplied data does not state supply voltages, output-noise values, or decoupling values, so those must not be inferred or copied from another LPC17xx board.
Do not treat a matching package as proof that any related LPC17xx device is an automatic drop-in replacement. LPC1768FBD100K adds CAN, LPC1766FBD100 has a different memory configuration, and the LPC1768 ordering suffixes can differ in packing rather than function. For an assembled board, compare the exact device identity, memory requirements, boot configuration, pin multiplexing, peripheral population, and firmware image. For a new PCB, treat the alternatives as redesign candidates until the NXP pin tables and errata are checked.
