LPC1752FBD80K 概要
A microcontroller is a programmable system-on-chip that integrates a processor core, nonvolatile program memory, volatile data memory, and peripherals into one package. The LPC1752 belongs to the Cortex-M3 -> 32-bit microcontroller -> embedded processor -> semiconductor hierarchy. It combines deterministic peripheral access with low power consumption for embedded control, communications, data acquisition, and industrial automation designs.
Key verified features include a 100 MHz maximum frequency, 64 KB of 64K x 8 flash, and 16 KB of data memory. The peripheral mix supports USB-connected control devices, multi-sensor measurement systems, CAN or serial network nodes, motor-control equipment, and data-logging platforms. Its eight-channel 12-bit ADC is useful when multiple analog inputs must be acquired, while the motor-control PWM and quadrature-encoder interface reduce the need for separate controller devices.
The Cortex-M3 architecture provides a 32-bit processing platform for control loops and protocol handling. The LPC1752 integrates communications and timing resources around that core, including four UARTs, two I2C interfaces, two SSP controllers, SPI, CAN, and USB Device. Its DMA controller can move data without requiring each transfer to be serviced by the CPU, which is valuable when the firmware must maintain deterministic timing across communication and control tasks.
Typical applications include USB data-acquisition controllers, CAN-connected industrial nodes, motor-control boards, encoder-based positioning systems, serial gateways, and compact embedded instrumentation. The 12 x 12 mm LQFP-80 package is suitable for multilayer PCB layouts where 0.5 mm lead pitch and exposed thermal considerations must be handled according to the manufacturer footprint guidance.
A key design consideration is firmware and peripheral reassignment. Although the device integrates many peripherals, firmware, startup code, pin multiplexing, clock configuration, and memory placement must be validated against the complete NXP datasheet before release. Do not infer equivalent behavior from a similarly named MCU without checking pin function, peripheral mapping, interrupt vectors, and electrical constraints.
This page combines verified manufacturer and distributor information with practical selection and design guidance. It also clearly separates confirmed facts from data that was not supplied, avoiding unsupported claims about electrical limits, package details, lifecycle status, or replacement compatibility.

主な用途
LPC1752FBD80K の用途: 7 件s: USB Data-Acquisition Controller, CAN-Connected Industrial Control Node, Motor-Control and Encoder Positioning, USB Service and Configuration Interface, Multi-Sensor Embedded Instrumentation, Serial Gateway and Protocol Converter, Compact Embedded Data Logger.
USB Data-Acquisition Controller
LPC1752FBD80K fits a USB-connected acquisition controller because the verified device combines a 100 MHz ARM Cortex-M3 core, an eight-channel 12-bit ADC, USB Device connectivity, and eight DMA channels. The MCU can sample multiple analog inputs and move data through DMA while the USB peripheral handles host communication, reducing CPU involvement during transfers. Four UARTs also leave room for external sensors or service ports. The 80-pin LQFP provides access to the integrated interface signals, but the exact pin mux, analog input routing, USB transceiver arrangement, and electrical limits must be checked in the NXP documentation. Firmware should define buffering, calibration, fault detection, and USB enumeration states before production testing.
おすすめ
CAN-Connected Industrial Control Node
The LPC1752FBD80K is a reasonable candidate for distributed industrial control because it provides one CAN channel alongside four UARTs, two I2C interfaces, two SSP interfaces, SPI, and an eight-channel 12-bit ADC. A controller can use CAN for peer communications, UARTs for local service or sensors, and the ADC for analog process inputs. DMA support is valuable when sensor or network traffic must remain scheduled while control software executes. The verified sources do not specify transceiver voltage levels, termination requirements, isolation, or industrial temperature qualification, so the final design must add the appropriate CAN transceiver and protection network and confirm the LPC1752 electrical and environmental limits from NXP documentation.
おすすめ
Motor-Control and Encoder Positioning
LPC1752FBD80K supports motor-control PWM and a quadrature-encoder interface, making it suitable for compact positioning and actuator-control boards. The 100 MHz Cortex-M3 core can execute control calculations, while the dedicated encoder interface can decode position signals and the ADC can monitor analog feedback such as current or temperature. Four UARTs and multiple serial interfaces allow connection to a host, parameter programmer, or external drive electronics. Because the verified data does not identify PWM frequency, encoder electrical limits, power-stage requirements, or thermal ratings, engineers should use the complete NXP datasheet and validate timing, isolation, gate-driver selection, and fault shutdown behavior on the target board.
おすすめ
USB Service and Configuration Interface
The integrated USB Device function supports a clean service path for configuration, diagnostics, logging, or firmware maintenance in embedded equipment. LPC1752FBD80K can expose a USB interface to a host while using its four UARTs and two SSP controllers for local equipment connections. This architecture is useful in instruments where a field technician needs a standardized service connector rather than a proprietary serial cable. The verified data confirms USB Device support but does not specify USB speed, endpoint arrangement, power sourcing, or transceiver implementation. Hardware and firmware decisions must therefore follow the NXP reference information and USB electrical requirements, while the 80-pin LQFP layout must preserve adequate signal integrity and decoupling around the MCU.
おすすめ
Multi-Sensor Embedded Instrumentation
The LPC1752FBD80K can serve as the central controller in a compact instrument that combines analog measurement with digital sensors and local communications. Its eight-channel 12-bit ADC supports multiple analog inputs, while two I2C interfaces accommodate low-speed sensors, two SSP controllers support synchronous serial devices, and SPI provides a higher-speed peripheral path. Four UARTs allow connection to external instruments or service ports, and DMA helps transfer data without excessive CPU intervention. The verified sources do not specify sample rate, ADC accuracy, reference voltage, sensor timing, or input multiplexing details, so these parameters must be checked before claiming measurement performance. Firmware should calibrate channels and implement range, saturation, and fault monitoring.
おすすめ
Serial Gateway and Protocol Converter
LPC1752FBD80K is suitable for a compact serial gateway because it combines four UARTs, two SSP controllers, SPI, two I2C interfaces, CAN, USB Device, and eight DMA channels. The gateway can translate between a host USB connection and embedded serial peripherals while distributing data through CAN or UART links. DMA reduces interrupt pressure when several ports move continuous data, and the 100 MHz core leaves headroom for protocol framing and buffering. The supplied results do not define baud-rate limits, USB throughput, CAN timing, peripheral pin mappings, or low-power modes. Final validation should include worst-case interrupt latency, buffer depth, electrical protection, and recovery behavior. The MCU should be selected only after confirming the required port count and protocol mix in the complete datasheet.
おすすめ
Compact Embedded Data Logger
The LPC1752FBD80K can act as the control processor for an embedded data logger when the design needs USB connectivity, serial sensors, analog acquisition, and deterministic peripheral handling. The eight-channel 12-bit ADC can collect process or test signals, while the four UARTs and two I2C interfaces connect to external sensors or storage electronics. USB Device support provides a convenient path for downloading records or configuring a unit, and DMA can support buffering while the Cortex-M3 core performs file and control tasks. The verified data does not identify external storage interfaces, log-format requirements, USB throughput, or endurance requirements. Engineers should validate the chosen storage medium, write buffering, power-loss recovery, clock strategy, and brownout behavior before using the MCU in unattended logging equipment.

設計ノート
Treat the LPC1752FBD80K as an 80-pin LQFP design and route all leads with the exact NXP footprint. The verified package is 12 x 12 mm, but the complete pad dimensions, exposed-pad arrangement, pin-1 orientation, and recommended land pattern were not supplied. Before fabrication, compare the PCB footprint against the current NXP package drawing and confirm that all power, ground, decoupling, and alternate-function pins are reachable without violating the manufacturer clearance and solderability guidance.
Implement the MCU power tree only after checking the complete NXP electrical specification for supply voltage, sequencing, current limits, and decoupling. Place required bulk and high-frequency decoupling capacitors close to the relevant supply pins and preserve low-return-path impedance from the device ground pins into the ground plane. Do not infer USB, ADC, or transceiver power requirements from the product-page summary; derive them from the official datasheet and the selected external-interface design.
Reserve pin-multiplexing options early in schematic capture because the LPC1752FBD80K integrates USB, four UARTs, CAN, SSP, SPI, I2C, ADC, PWM, and encoder functions. A footprint-compatible substitution is not enough: an alternate function may move to a different ball or lead, and a peripheral may share a pin with another block. Freeze the pin assignment after reviewing the complete pin table, then reserve routing for external transceivers, protection devices, clocks, reset, and programming/debug access.
For USB, high-speed SSP, SPI, or other timing-sensitive interfaces, follow the manufacturer’s recommended termination, impedance, and reference-plane arrangements. Keep clock and high-speed traces short, avoid unnecessary stubs, and provide a continuous ground reference where the package permits. The verified data identifies the interfaces but does not provide trace-impedance, rise-time, or timing values, so these requirements must be confirmed in the NXP hardware design guidance and the selected peripheral specifications.
Do not substitute a similar-looking LPC17xx or Cortex-M3 part solely by package name or marketing frequency. Check memory size, pin names, alternate-function mapping, USB and CAN availability, ADC channels, DMA behavior, clock tree, package temperature grade, and firmware startup requirements. A replacement that is electrically related can still require board respin, software changes, or a different programming and debug setup. This record does not assert unverified drop-in alternatives.
