LPC1763FBD100K - 100MHz Cortex-M3 256KB Flash | NXP
料号： LPC1763FBD100K ✓ 量产中LPC1763FBD100K 概述
The core ARM Cortex-M3 architecture supports efficient event-driven control and real-time signal handling. Its integrated peripherals include an 8-channel DMA controller, four UARTs, three SSP/SPI interfaces, three I2C interfaces, I2S, an 8-channel 12-bit ADC, a 10-bit DAC, motor-control PWM, a Quadrature Encoder interface, four general-purpose timers, and six additional timer-related functions identified in the manufacturer product information. These resources reduce the need for external peripherals in industrial controllers, data-acquisition systems, motor-control platforms, and connected embedded equipment.
Communication interfaces are the central strength of the LPC1763 family. The four UARTs support asynchronous serial communication, while SSP/SPI and I2C interfaces connect to sensors, displays, memory, and expansion devices. The I2S interface supports digital audio paths, and the integrated ADC and DAC allow analog measurements and signal generation without requiring separate converters in suitable designs. The 8-channel DMA controller enables efficient transfers between peripherals and memory, reducing processor involvement in repetitive data movement.
For motor and motion applications, the dedicated motor-control PWM and Quadrature Encoder interface support closed-loop positioning, speed measurement, and actuator control. The 12-bit ADC provides a practical resolution for many industrial, instrumentation, and consumer-control tasks, while the 10-bit DAC supports control-signal generation and test functions. The combination of flash, SRAM, high-speed serial interfaces, and dedicated motion-control peripherals makes the device suitable for gateways, embedded instruments, motor controllers, and communication bridges.
PCB design should account for the 100-pin LQFP footprint, the 3.3 V supply arrangement, decoupling requirements, oscillator support, programming access, and signal routing to external memories or peripherals. Confirm startup, pin multiplexing, and peripheral configuration against the NXP datasheet and application guidance before releasing the PCB. The manufacturer documents the LPC1763 as a 100 MHz Cortex-M3 device with 256 KB flash, 64 KB data memory, and low-power characteristics for embedded systems.
This product overview combines manufacturer and distributor information with application guidance for engineers evaluating the LPC1763FBD100K. It highlights the device's processing, connectivity, analog, and motion-control resources while directing designers to the official datasheet for authoritative pin, timing, electrical, and programming details.

典型应用
LPC1763FBD100K 适用于 6 应用s: Industrial Data Acquisition, Motor Control and Position Feedback, Serial Communication Gateway, Audio Signal Processing, IoT Sensor Node, Embedded Test and Measurement.
Industrial Data Acquisition
The LPC1763FBD100K fits industrial measurement systems that combine multiple analog inputs with reliable serial data transfer. Its 8-channel 12-bit ADC provides a practical resolution for sensors and process monitoring, while the 8-channel DMA controller can move sampled data without tying up the 100 MHz Cortex-M3 core on every transfer. Four UARTs and three I2C interfaces allow the controller to communicate with external transceivers, data loggers, and expansion modules. At 3.3 V in a 100-LQFP package, it supports compact embedded instrumentation while leaving USB, Ethernet, or isolated communication interfaces available for higher-level system functions.
推荐
Motor Control and Position Feedback
The LPC1763FBD100K is suitable for motor controllers requiring fast computation, dedicated PWM, and position feedback. Its motor-control PWM and Quadrature Encoder interface support speed and position control loops, while four general-purpose timers provide timing for complementary or sequential operations. The 100 MHz Cortex-M3 core can execute control algorithms and manage communications concurrently, and the 8-channel DMA controller improves data-transfer efficiency. Designers can use the 12-bit ADC for current or position sensing and the four UARTs for tuning, diagnostics, and a host interface within the same 3.3 V embedded platform.
推荐
Serial Communication Gateway
The LPC1763FBD100K works well in a multi-protocol communication gateway because it combines four UARTs, three SSP/SPI interfaces, and three I2C interfaces in a single microcontroller. Its 256 KB flash supports gateway firmware, configuration, and protocol conversion, while 64 KB of SRAM accommodates message buffers and temporary protocol data. The 8-channel DMA controller helps sustain serial traffic, and the Cortex-M3 core can manage several communication tasks concurrently. This arrangement is useful for industrial bridges, equipment controllers, and service interfaces where legacy UART devices must be connected to SPI or I2C peripherals.
推荐
Audio Signal Processing
The LPC1763FBD100K can serve as the control and signal-processing center in embedded digital-audio equipment. Its I2S interface supports digital audio data transfer, while the 12-bit ADC and 10-bit DAC provide analog measurement and output paths for monitor, test, or control applications. Four UARTs allow configuration and telemetry, and the 8-channel DMA controller efficiently transfers audio blocks through memory. The 100 MHz Cortex-M3 core provides more processing headroom than typical low-end Cortex-M0+ controllers, making the device relevant for audio appliances, sound controllers, and compact instrumentation requiring more than basic connectivity.
推荐
IoT Sensor Node
The LPC1763FBD100K supports connected sensor nodes where several peripherals, local processing, and serial communications are required. The 8-channel 12-bit ADC can acquire environmental or conditioning signals, three I2C ports can connect common digital sensors, and the SSP/SPI interfaces can serve external radios or memory. Low-power characteristics and DMA-assisted transfers suit responsive embedded designs. Four UARTs provide expansion and diagnostic channels, while 256 KB flash and 64 KB SRAM are sufficient for moderate protocol stacks, control logic, and local buffering in a 100-LQFP 3.3 V implementation.
推荐
Embedded Test and Measurement
The LPC1763FBD100K is a practical controller for compact automated test equipment because it combines fast control logic, flexible serial interfaces, and onboard analog conversion. The 12-bit ADC can acquire sensor or stimulus feedback, while the 10-bit DAC can generate basic control waveforms. Three SSP/SPI channels support instruments and memories, and four UARTs handle test commands and results. With 256 KB flash, 64 KB SRAM, and eight DMA channels, the device can coordinate deterministic data movement across a 3.3 V embedded test platform without requiring a separate communications processor.

关键差异点
- Higher CPU performance than the LPC11U68 comparison family （对比 LPC11U68JBD100E)
- Broader serial interface selection in the same NXP family （对比 LPC1766FBD100)
- Direct LPC176x resource profile for designs without CAN （对比 LPC1769FBD100K)
设计说明
Place the required 3.3 V supply and decoupling network directly beside the LPC1763FBD100K power pins. Keep each supply path short, use the capacitor values and placement specified in the NXP design guidance, and provide adequate source current for the processor, analog converters, and enabled communication peripherals. Separate noisy digital return paths from analog ground references where the board architecture supports a partitioned ground plane.
Design the 100-LQFP footprint to the manufacturer land pattern and maintain the specified lead, pad, solder-mask, and paste geometry. Route the 100 MHz clock and high-speed signals away from noisy switching nodes, provide a continuous ground reference beneath signal paths, and place oscillator, bypass, and debug-access components where they remain mechanically stable and electrically short.
Do not assume that another LPC17xx device with the same package is firmware-compatible without checking pin multiplexing, memory sizes, peripheral availability, and startup requirements. The LPC1763FBD100K notably has no CAN interface, so designs migrating to a CAN-equipped family member may require both software changes and board-level routing changes.
Use the datasheet pin-muxing table to assign alternate functions before routing. Treat clock, debug, communications, and analog inputs as separate signal groups, and provide low-impedance returns for high-speed edges. Where SPI, I2S, or UART signals leave the controller, check connector and cable requirements for series termination, ground-reference strategy, and isolation needs.
