LPC1758FBD80K Descripción general
A microcontroller is a programmable embedded-system component that combines a processor core, memory, communication peripherals, timers, and analog interfaces on one integrated circuit. In the device hierarchy, the LPC1758FBD80K is an ARM Cortex-M3 microcontroller, a 32-bit embedded MCU, and a member of NXP's LPC17xx family. Its integration reduces component count and simplifies firmware-driven control, data acquisition, communications, and actuator management.
The principal features include 100 MHz processing, 512 KB flash, 64 KB data memory, Ethernet, USB 2.0 connectivity, and extensive serial-peripheral support. Eight DMA channels can move data with reduced processor intervention, while four UARTs and two CAN channels support multiple industrial and communications links. The 12-bit ADC and integrated DAC provide analog measurement and output capability, and the motor-control PWM and quadrature encoder resources suit closed-loop motion systems.
The ARM Cortex-M3 architecture supports efficient real-time embedded control while the extensive peripheral set allows multiple functions to share one controller. Eight-channel DMA is especially useful for simultaneous sampling, waveform generation, Ethernet servicing, and transfers to or from external peripherals. Integrated USB and Ethernet provide two distinct high-speed connectivity paths, although firmware drivers, transceiver requirements, connector implementation, and protocol stacks remain design responsibilities.
Typical applications include industrial automation, Ethernet-connected equipment, USB data acquisition, CAN network nodes, motor and encoder control, metering, data logging, and low-power embedded boards. The LPC1758FBD80K is appropriate when one device must provide substantial memory, serial connectivity, analog conversion, and deterministic peripheral access without requiring a higher-complexity processor.
PCB design should preserve clean power, ground, clock, high-speed communication, and analog signal paths in accordance with the manufacturer datasheet. Decoupling, exposed-pad thermal management, Ethernet magnetics, USB routing, and differential-pair geometry must be validated for the selected board stack-up. Firmware should also include clock, USB, Ethernet, CAN, DMA, and analog-conversion initialization before production use.
This page consolidates verified distributor and manufacturer information with interface-focused engineering guidance. It also distinguishes exact published LPC1758FBD80 specifications from parameters that require confirmation from the complete manufacturer datasheet before design release.

Aplicaciones típicas
LPC1758FBD80K es adecuado para 8 aplicacións: Industrial Automation Controller, CAN Network Control Node, USB Data-Acquisition System, Motor Control and Encoder Feedback, Ethernet-Connected Monitoring Equipment, Metering and Data Logger, Audio and Digital Signal Interface, Secure Network Appliance Controller.
Industrial Automation Controller
The LPC1758FBD80K fits industrial automation because its 100 MHz Cortex-M3 core coordinates two CAN channels, four UARTs, eight DMA channels, Ethernet, and 12-bit analog conversion on one MCU. The 512 KB flash and 64 KB data memory support control firmware, communications buffers, and supervisory logic. Use the CAN and UART interfaces for fieldbus or service links, Ethernet for supervisory communication, and DMA for transferring sensor or actuator blocks with reduced CPU involvement. Final suitability depends on verified supply voltage, temperature grade, isolation, protection, and functional-safety requirements.
Recomendado
CAN Network Control Node
The LPC1758FBD80K is suitable for a CAN network node because NXP specifies two CAN channels alongside a 100 MHz Cortex-M3 core and 512 KB flash. Firmware can manage message filtering, periodic status frames, event logging, diagnostics, and coordination with local actuators. Eight DMA channels can support background movement of data between memory and communication peripherals, while the ADC and motor-control PWM resources assist sensor acquisition and closed-loop outputs. An isolated CAN transceiver, termination, surge protection, grounding strategy, and safety-compliant software remain external design requirements.
Recomendado
USB Data-Acquisition System
The LPC1758FBD80K supports USB Device, Host, and OTG operation, 8-channel 12-bit ADC conversion, multiple serial buses, eight DMA channels, and 512 KB flash. These resources fit data loggers, laboratory interfaces, portable instruments, and embedded test equipment where measured analog data must be transferred to a host without excessive CPU overhead. DMA can buffer conversion and communications data, while the DAC supports stimulus or reference output. USB connector protection, device or host support components, firmware stack configuration, impedance-controlled routing, and verified electrical limits must be developed separately.
Recomendado
Motor Control and Encoder Feedback
The LPC1758FBD80K combines motor-control PWM, a quadrature encoder interface, eight-channel 12-bit ADC, and a 100 MHz Cortex-M3 core for real-time motor-control tasks. The PWM resources can generate commanded drive signals, the ADC can monitor current or position-related analog feedback, and the quadrature interface can decode incremental encoder motion. DMA can reduce transfers to memory while control calculations run. Practical implementations still require power stages, gate drivers, current sensing, voltage protection, filtering, grounding, and timing verification against the complete datasheet.
Recomendado
Ethernet-Connected Monitoring Equipment
The LPC1758FBD808 is a strong fit for Ethernet-connected monitoring equipment because it integrates Ethernet, 100 MHz processing, 512 KB flash, 64 KB data memory, ADC, DAC, and multiple serial peripherals. It can acquire sensor data, maintain local control, log events, and expose data through an Ethernet network while USB provides an alternate maintenance or local-host path. The eight-channel 12-bit ADC supports multi-input monitoring, and DMA can improve data throughput. Production boards still need qualified magnetics, isolation decisions, controlled-impedance routing, surge protection, and complete protocol-stack validation.
Recomendado
Metering and Data Logger
The LPC1758FBD80K supports metering and logging functions with its eight-channel 12-bit ADC, DAC, four UARTs, two CAN channels, Ethernet, USB, and 64 KB data memory. Multiple analog inputs can be sampled while communications peripherals report measurements or transfer records to a host. DMA assists in moving acquisition and logging data, and the Cortex-M3 core performs calibration, filtering, and supervisory control. Analog accuracy depends on reference quality, excitation, front-end design, calibration, and grounding. External nonvolatile storage, data integrity protection, and long-term supply planning are application-specific additions.
Recomendado
Audio and Digital Signal Interface
The LPC1758FBD80K can serve as the control hub in audio or mixed-signal equipment because it provides I2S, I2C, SPI, SSP, USB, ADC, DAC, and DMA resources. A system can sample or generate digital audio, route control data, maintain timing, and expose configuration through USB or Ethernet. The 100 MHz Cortex-M3 core and 512 KB flash provide room for control code and interface drivers, while DMA helps maintain continuous data flow. Audio-clock design, grounding, codec requirements, signal levels, latency targets, and exact peripheral mappings must be confirmed before layout or firmware commitment.
Recomendado
Secure Network Appliance Controller
The LPC1758FBD80K is suitable for embedded network-appliance control when both Ethernet and USB are useful but an application does not require a high-end application processor. Its 100 MHz Cortex-M3 core, 512 KB flash, and 64 KB data memory can support protocol processing, management, logging, and peripheral control. Four UARTs and two CAN channels provide service and sensor links, while the ADC can monitor health signals. It is not presented as a substitute for cryptography-focused secure-element parts; any security boundary requires a dedicated hardware root of trust, protected keys, secure boot, and threat modeling.

Notas de diseño
Base the footprint and all 80 connections on the official LPC1758FBD80 package drawing rather than the distributor snippet alone. Confirm whether the thermal or exposed pad is electrically designated, which power pins must be tied together, and whether unused pins have defined levels. Place required bypass capacitors close to their intended supply pins and preserve a continuous ground reference beneath the device where the package and board stack-up permit.
Separate analog and digital return paths where practical, keep the 12-bit ADC inputs away from switching nodes and high-current motor-drive returns, and provide local filtering at analog pins. The verified MCU integrates ADC, DAC, Ethernet, USB, CAN, and motor-control resources, so simultaneous use can create conflicting noise and return-current requirements. Validate reference voltage, analog input impedance, acquisition time, and grounding against the complete electrical specification before setting sample rates.
Ethernet and USB are high-speed differential interfaces and cannot be treated like general-purpose low-speed routing. Determine target impedance from the complete interface specification, preserve continuous reference planes, minimize stubs and vias, and control differential spacing and length behavior through board-stack-up calculation and measurement. USB connector protection, Ethernet magnetic components, isolation boundaries, and ESD design must be coordinated with the enclosure and grounding architecture.
Do not assume that an LPC17xx family member is pin-compatible merely because it uses a Cortex-M3 core or a related package. The retrieved LPC1785FBD208K and LPC1776FBD208 comparison references do not prove an 80-LQFP pin match. For any substitute, compare every package terminal, supply tolerance, I/O type, analog limit, clock requirement, peripheral mapping, bootloader behavior, and firmware dependency before removing the original part.
The supplied search data does not specify supply voltage, current limits, or absolute maximum ratings, so those values must be taken from the full NXP datasheet before power-supply and decoupling design. Account for 100 MHz operation, analog references, Ethernet PHY or magnetics when present, USB loads, and external power domains when sizing the board supply. Avoid inferring a regulator selection from processor frequency alone; calculate worst-case load and startup conditions from verified data.
Información de cumplimiento
The supplied NXP, DigiKey, Mouser, Octopart, and third-party search snippets do not explicitly state compliance declarations for LPC1758FBD80K. Compliance and automotive qualification must be confirmed using current official NXP documentation before design release.
