LPC1764FBD100K - 100MHz Cortex-M3 MCU with Ethernet | NXP
MPN: LPC1764FBD100K ✓ فعالLPC1764FBD100K نمای کلی
A microcontroller is a programmable integrated circuit containing a processor core, memory, and communication peripherals on one device. The LPC1764 belongs to the ARM Cortex-M3 microcontroller family, which sits within the broader embedded processor and semiconductor hierarchy. Unlike a general-purpose application processor, this device is designed for real-time control, sensor monitoring, communications, and system management tasks where deterministic peripheral access and compact embedded integration are important.
The LPC1764's three principal characteristics are its 100 MHz Cortex-M3 operating frequency, 128 kB flash memory, and 32 kB SRAM. Flash supports firmware and nonvolatile configuration storage, while SRAM provides working memory for stacks, buffers, protocol handling, and real-time data processing. The Ethernet MAC and USB Device controller add wired network and USB connectivity without requiring separate interface devices. The integrated CAN controllers support industrial networking, and the four UARTs provide multiple serial communication channels.
The peripheral set is designed to reduce external component count in embedded systems. Eight DMA channels can move data between memory and peripherals while the CPU performs other tasks, improving responsiveness in data-heavy designs. Three SSP/SPI and three I2C interfaces suit sensors, flash memory, displays, and expansion devices. The 8-channel 12-bit ADC supports analog monitoring, while motor-control PWM and the quadrature encoder interface address motion and motor-control systems. The 100-pin LQFP package exposes these resources while remaining compatible with conventional PCB assembly methods.
Typical applications include Ethernet-connected industrial controllers, USB data-acquisition equipment, CAN-based automation nodes, serial gateways, motor-control boards, and embedded instrumentation. The 128 kB flash capacity can accommodate substantial application firmware, while 32 kB SRAM supports network buffering and protocol state. When firmware exceeds local memory, designers should evaluate the LPC1768 or other family members rather than assuming every larger-memory variant is a drop-in replacement.
Design considerations include separating analog and digital return paths, providing local decoupling at the 3.3 V supply pins, and routing Ethernet differential pairs according to the manufacturer layout guidance. Firmware should also handle DMA alignment and peripheral interrupt priorities. Because the verified material does not provide a complete public pin table or detailed thermal and timing figures in the supplied excerpts, those values are not inferred in this record.

کاربردهای معمول
LPC1764FBD100K مناسب است برای 6 کاربردs: Industrial Ethernet Controller, USB Data-Acquisition System, CAN-Based Automation Node, Motor and Encoder Control, USB Communications Gateway, Embedded Instrumentation and Sensor Node.
Industrial Ethernet Controller
The LPC1764FBD100K fits industrial Ethernet controllers because it combines a 100 MHz ARM Cortex-M3 core with an integrated Ethernet MAC, 8-channel DMA, and 128 kB of flash. The DMA can transfer network data with reduced CPU intervention, while 32 kB of SRAM supports packet buffers, protocol state, and diagnostics. An external Ethernet physical-layer transceiver, isolation components, magnetics, and connector are still required to create a physical network port. This integration is valuable when a board must combine network management, local control, and serial-device connectivity without using multiple processors.
پیشنهادی
USB Data-Acquisition System
The LPC1764FBD100K is suitable for USB-connected data acquisition because its USB Device controller can interface directly with a host while the 8-channel 12-bit ADC performs analog measurements. Four UARTs and three I2C channels allow the same controller to collect data from sensors and communicate with local equipment. Its 100 MHz Cortex-M3 core provides processing capacity for filtering and packet preparation, and the 8-channel DMA can move samples efficiently. Designers should budget USB routing, ESD protection, analog filtering, reference design, and appropriate data-acquisition calibration.
پیشنهادی
CAN-Based Automation Node
The LPC1764FBD100K fits CAN-based automation nodes because it provides two CAN channels, four UARTs, three I2C ports, and 8-channel DMA alongside the 100 MHz Cortex-M3 processor. These resources allow a single controller to manage a CAN network while performing local acquisition and serial diagnostics. The integrated 12-bit ADC supports analog process monitoring, and the 128 kB flash capacity accommodates application firmware and configuration data. A protected CAN transceiver and correctly terminated bus interface are required, with isolation considered for installations spanning long or noisy cable runs.
پیشنهادی
Motor and Encoder Control
The LPC1764FBD100K supports motor and encoder control through its dedicated motor-control PWM resources, quadrature encoder interface, and 8-channel 12-bit ADC. The 100 MHz Cortex-M3 core can execute control algorithms while DMA and serial peripherals handle independent data movement. The three I2C and three SSP/SPI channels allow connection to position sensors, gate drivers, current sensors, and configuration devices. Practical designs must manage motor-current spikes, grounding, filtering, and timing margins, and must verify the exact PWM and encoder pin assignments in the manufacturer pinout.
پیشنهادی
USB Communications Gateway
The LPC1764FBD100K is suitable for a USB communications gateway because it places USB Device, Ethernet MAC, four UARTs, two CAN channels, and three I2C interfaces around one processor. The 32 kB SRAM can hold protocol buffers, and the 8-channel DMA supports efficient transfers between memory and communications peripherals. The gateway can translate between USB-connected host software and embedded field-bus or serial equipment without a separate interface processor. A real implementation still needs suitable transceivers, ESD protection, protocol firmware, and careful separation of high-speed digital routing from sensitive analog sections.
پیشنهادی
Embedded Instrumentation and Sensor Node
The LPC1764FBD100K fits embedded instrumentation and sensor nodes because its 8-channel 12-bit ADC, three I2C channels, three SSP/SPI channels, and four UARTs provide several ways to collect and forward measurements. The 100 MHz core can perform local filtering, calibration, and data packaging, while 128 kB flash stores firmware and configuration. Ethernet or USB provides a higher-speed path to a host, whereas CAN or UART supports slower field equipment. Engineering effort should focus on analog reference quality, input protection, calibration, low-noise grounding, and deterministic peripheral scheduling.

یادداشت‌های طراحی
Design the LPC1764FBD100K supply around its documented 2.4 V to 3.6 V operating range and nominal 3.3 V rail. Place the required local bypass capacitors close to the device power pins, provide a low-impedance return path, and keep switching-converter routing away from the analog inputs. The verified material does not provide the complete decoupling network or absolute maximum ratings, so engineers must follow the manufacturer datasheet and power-reference schematic rather than infer capacitor values.
Route Ethernet and other high-speed interfaces as controlled-impedance or differential pairs where applicable, following the NXP layout guidance. The Ethernet MAC requires an external physical-layer device, magnetics, and connector, so the MCU, transceiver, isolation barrier, and protection components should be planned as one signal chain. Keep the analog ground and digital return strategy deliberate, especially around the 8-channel 12-bit ADC, motor-control PWM, and quadrature encoder signals.
Do not treat the LPC1764FBD100, LPC1764FBD100K, and related LPC17xx designations as automatically interchangeable. Confirm the exact ordering code, package form, pin assignments, boot configuration, and supplied interface mix. Likewise, sharing an LQFP-100 body with another MCU does not establish pin-to-pin compatibility. Validate every power, ground, debug, analog, communications, and motor-control signal in the manufacturer documentation before reusing an existing PCB.
