LPC1759FBD80K Présentation
A Cortex-M3 microcontroller is a 32-bit reduced-instruction-set processor designed for embedded systems. The LPC1759 belongs to the MCU hierarchy: microcontroller, embedded processor, ARM Cortex-M core, and integrated semiconductor device. Its combination of local flash, SRAM, serial interfaces, USB, analog conversion, timers, and DMA enables one device to supervise real-time control and communication tasks without requiring a separate host processor.
Verified product information identifies a 120 MHz operating frequency, 512 KB flash, 64 KB SRAM, 4 UARTs, 2 CAN channels, 2 SSP controllers, 1 SPI interface, 2 I2C interfaces, I2S, an 8-channel 12-bit ADC, a DAC, motor-control PWM, and a quadrature encoder interface. USB Device, Host, and OTG modes broaden its suitability for USB peripherals, service interfaces, and portable embedded systems.
The peripheral mix supports several concurrent workloads. DMA can transfer data between peripherals and memory, while UART, CAN, SPI, I2C, and USB interfaces connect sensors, human-interface modules, industrial networks, and service equipment. The 12-bit ADC and DAC support analog measurement and signal generation, and the PWM plus quadrature encoder resources are useful for motor and position-control systems.
Typical applications include industrial data acquisition, USB-to-serial gateways, CAN-connected machinery, laboratory instruments, building-control equipment, and compact embedded controllers. At 120 MHz, the Cortex-M3 core provides processing headroom for protocol handling and control logic, while the integrated peripherals reduce the need for external interface devices.
A critical design consideration is the LPC1759's broad supply-voltage and pin-function network: the datasheet snippet identifies 2.5 V/3.3 V operation, while exact operating limits and decoupling requirements are not included in the supplied data. Board designers should therefore verify the manufacturer datasheet for power sequencing, USB transceiver requirements, peripheral pin multiplexing, and LQFP thermal and layout guidance.
This page combines verified manufacturer and distributor information with purchasing context and practical integration guidance. It distinguishes confirmed LPC1759FBD80K features from unverified details and focuses alternatives on same-package compatibility rather than presenting electrically different MCUs as drop-in replacements.

Applications typiques
LPC1759FBD80K convient pour 6 applications: Industrial Data Acquisition, USB Service Interface, CAN-Connected Machinery, USB-to-Serial Gateway, Position and Motor Control, Building and Environmental Control.
Industrial Data Acquisition
The LPC1759FBD80K fits compact industrial measurement systems that need local control, analog inputs, and communications in one MCU. Its verified 8-channel 12-bit ADC can acquire multiple sensor signals, while the 120 MHz Cortex-M3 core handles sampling coordination, filtering, and control logic. Four UARTs and 2 CAN channels provide paths to sensors, service consoles, remote nodes, and industrial equipment. The 512 KB flash supports application firmware, configuration data, and communication stacks, while 64 KB of data memory can support buffering. For a robust design, verify the ADC timing, input range, calibration method, electrical limits, and calibration strategy from the complete manufacturer datasheet before setting sample rates or safety limits.
Recommandé
USB Service Interface
The LPC1759FBD80K is suitable for a USB-connected embedded service port because it supports USB Device, Host, and OTG operation. A USB interface can replace a large collection of serial-port components in a controller, configuration tool, or peripheral while retaining the 4 UARTs for legacy equipment. The 120 MHz Cortex-M3 core leaves processing capacity for protocol handling and application logic, and the 8-channel DMA controller can improve data movement for USB and serial traffic. The board design still needs verified USB transceiver, connector, power, impedance, and signal-integrity decisions; these are system-level requirements not fully specified by the supplied search snippets.
Recommandé
CAN-Connected Machinery
The LPC1759FBD80K fits CAN-connected machinery that needs both network communication and deterministic embedded control. Its two CAN channels can support communication with sensors, drive electronics, operator stations, or other embedded controllers. The motor-control PWM and quadrature encoder interface make the MCU relevant to position and motion-control subsystems, while the 4 UARTs remain available for local sensors and diagnostics. The 120 MHz core and 8-channel DMA help separate protocol traffic from control work, but the design must verify CAN timing, transceiver requirements, isolation strategy, fault handling, pin multiplexing, and motor-driver limits in the complete NXP documentation.
Recommandé
USB-to-Serial Gateway
The LPC1759FBD80K can serve as the controller in a USB-to-serial gateway where USB connectivity must coexist with multiple legacy communication ports. USB Device, Host, and OTG support provides a flexible host-side architecture, while the four UARTs can connect to external transceivers or service headers. The Cortex-M3 core at 120 MHz can manage framing, buffering, and protocol conversion, and the 8-channel DMA controller can reduce CPU involvement in transfers. For production, verify USB electrical requirements, UART voltage levels, baud-rate support, ESD protection, connector design, and the exact package pin assignments; those details are not present in the supplied snippets.
Recommandé
Position and Motor Control
The LPC1759FBD80K is relevant to compact position-control and motor-control systems because it combines a 120 MHz Cortex-M3 core with motor-control PWM and a quadrature encoder interface. Those resources can support encoder decoding, speed estimation, and closed-loop control while the 8-channel 12-bit ADC samples current, position, or temperature feedback. The two CAN channels can connect the controller to a larger machine network, and the four UARTs can support debugging or local configuration. Actual suitability depends on unverified motor-driver topology, PWM frequency, ADC acquisition time, current sensing accuracy, thermal conditions, and protection requirements, so use the manufacturer datasheet before selecting components or control-loop timing.
Recommandé
Building and Environmental Control
The LPC1759FBD80K can act as a local controller in a building-control or environmental-monitoring node. Four UARTs and two CAN channels allow the MCU to coordinate distributed sensors and actuators, while the 8-channel 12-bit ADC can acquire analog measurements from temperature, humidity, occupancy, or air-quality front ends. Its 120 MHz processing capability supports protocol management, filtering, and local logic, and 512 KB flash leaves room for firmware and configuration. For field deployment, verify low-power behavior, watchdog requirements, sensor accuracy, EMC constraints, connector protection, and supply behavior; those parameters are not available in the supplied verified data and must come from the full manufacturer documentation.

Notes de conception
Use a power plan that follows the exact LPC1759FBD80 datasheet for core, I/O, analog, and USB supply requirements. The verified distributor material identifies 2.5 V/3.3 V operation, but it does not provide individual rail tolerances, current limits, sequencing rules, or decoupling values. Place required bypass capacitors close to the relevant pins, preserve the permitted voltage levels on unused I/O, and verify USB transceiver power requirements separately from MCU digital rails.
Do not finalize the 80-LQFP footprint or peripheral assignments from the package size alone. The verified source confirms an 80-LQFP, 12 x 12 mm package, but the supplied data does not include the complete pin list. Before PCB release, compare the NXP package drawing and datasheet pin table for power pins, ground pins, USB signals, ADC inputs, oscillator connections, reset, boot, and all alternate-function muxing. This is especially important because moving a CAN, UART, SSP, or PWM signal can change the entire board architecture.
Avoid selecting LPC1759FBD80, LPC1759FBD80K, or LPC1759FBD80,551 solely by the visible base-number similarity. The suffixes can encode ordering and packaging information that is not explained in the supplied snippets. Confirm the manufacturer ordering table, temperature grade, package, pinout, flash configuration, and marking before substituting a related part. A compatible software family is not sufficient evidence of a drop-in electronic replacement.
Informations de conformité
The supplied NXP and distributor snippets do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Verify the current manufacturer declarations for the exact ordering code before production release.
