LPC1763FBD100Y - 100MHz Cortex-M3 MCU | NXP Semiconductors
料号： LPC1763FBD100Y ✓ 量产中LPC1763FBD100Y 概述
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals into one device. The Cortex-M3 processor provides a compact 32-bit architecture with deterministic interrupt handling, while the LPC1763FBD100Y adds communication, analog, timing, and data-movement peripherals needed by industrial controllers, embedded gateways, and connected equipment. Its family position is microcontroller → 32-bit embedded MCU → ARM Cortex-M3 microcontroller → NXP LPC17xx series.
Communication resources include four UARTs, three SSP/SPI interfaces, three I2C interfaces, and an I2S interface. These peripherals allow simultaneous connection of sensors, displays, external flash, audio codecs, and service interfaces. The eight-channel 12-bit ADC supports analog measurement, while the 10-bit DAC provides an analog output for control, waveform generation, or biasing. An eight-channel DMA controller reduces interrupt overhead during high-rate peripheral transfers.
The LPC1763FBD100Y includes motor-control PWM, a Quadrature Encoder interface, and four general-purpose timers, making it suitable for motion-control systems that require deterministic timing. Its integration is valuable when board area, firmware complexity, and peripheral sharing are priorities. Compared with a discrete processor implementation, the device can reduce external interface count and simplify synchronization between analog sampling, communications, and timing functions.
Typical uses include industrial automation controllers, motor-drive interfaces, data-acquisition equipment, building-control gateways, embedded serial-to-Ethernet equipment, and compact industrial user-interface modules. The 256 kB flash capacity supports a bootloader plus a moderate embedded application, while 64 kB of SRAM accommodates protocol buffers, sampling data, graphics state, and real-time control variables. The 100 MHz Cortex-M3 core provides additional computing headroom for networking stacks and supervisory logic.
Designers should match all 100 package pins against the manufacturer pin description before layout release and preserve the device's power, ground, decoupling, clock, and programming requirements. Firmware should also validate peripheral availability because closely related LPC17xx devices can differ in memory, Ethernet, CAN, and other integrated functions. For existing LPC1763FBD100 designs, the LPC1763FBD100Y ordering code is the subject of this data sheet and product record.
This page combines the official LPC1763 product information with distributor packaging details, practical interface guidance, drop-in-family comparisons, and application-specific design guidance. It helps engineers distinguish the exact LPC1763FBD100Y configuration from related LPC17xx devices before committing a 100-lead LQFP design to production.

典型应用
LPC1763FBD100Y 适用于 6 应用s: Industrial Automation Controller, Brushless Motor Controller, Industrial Data-Acquisition Module, Building-Control Gateway, Serial Protocol Bridge, Embedded Audio Interface.
Industrial Automation Controller
The LPC1763FBD100Y fits an industrial automation controller that must coordinate sensors, actuators, and service communications in one 100 MHz embedded platform. Its four UARTs support barcode scanners, serial instruments, or service consoles, while three I2C channels can connect sensors and I/O expanders. The eight-channel 12-bit ADC supports process monitoring, and eight-channel DMA moves sampled data with less processor intervention. Four general-purpose timers provide independent timing for scan cycles and output events. Integrating these functions reduces the number of external interface devices and keeps control-loop timing within one MCU domain.
推荐
Brushless Motor Controller
The LPC1763FBD100Y is well suited to a brushless motor controller combining position feedback, PWM generation, and current or voltage measurement. Its motor-control PWM and Quadrature Encoder interface support closed-loop commutation and position tracking, while the eight-channel 12-bit ADC can sample phase-current or position-sensor signals. The 100 MHz Cortex-M3 core leaves processing margin for a control loop and supervisory functions, and eight-channel DMA can transfer timing-critical samples. External MOSFET gate drivers, current-sense conditioning, and protection remain necessary because those power-stage functions are outside the MCU.
推荐
Industrial Data-Acquisition Module
The LPC1763FBD100Y supports a compact data-acquisition module built around its eight-channel 12-bit ADC and eight-channel DMA controller. DMA can transfer sampled data while the 100 MHz core performs filtering, calibration, and packet preparation, reducing the interruption burden of repeated conversions. Three SSP/SPI channels can connect external flash, ADC stages, or field-programmable sensors, while four UARTs provide configuration and diagnostic links. The 64 kB SRAM provides room for acquisition buffers, and the 256 kB flash can hold firmware, calibration constants, and communication protocols.
推荐
Building-Control Gateway
The LPC1763FBD100Y can serve as a building-control gateway where multiple low-speed sensors and actuators share a compact controller. Three I2C interfaces suit environmental sensors and digital I/O devices, three SSP/SPI channels support local expansion, and four UARTs connect controllers, displays, or service tools. The 10-bit DAC can generate analog control or test signals, while the 12-bit ADC supports supervisory measurements. A bootloader stored in flash can support field updates, and the 64 kB SRAM provides protocol buffers without requiring a separate communications processor.
推荐
Serial Protocol Bridge
The LPC1763FBD100Y is appropriate for a multi-protocol industrial bridge because it combines four UARTs with three SSP/SPI and three I2C controllers. Firmware can translate between legacy serial equipment and a local embedded network while the DMA controller handles repetitive transfers. Its 100 MHz Cortex-M3 core can support protocol conversion, filtering, and diagnostic logging in one device. The integrated ADC and DAC also allow the bridge to monitor a supply rail or generate a test output. Protocol timing and buffer sizes must be sized together to avoid overrun under worst-case traffic.
推荐
Embedded Audio Interface
The LPC1763FBD100Y can support an embedded audio interface because it includes I2S alongside three SSP/SPI channels, four UARTs, and a 10-bit DAC. I2S can connect a suitable audio codec, while the DAC can provide a basic analog output for monitoring or low-complexity signal generation. The eight-channel 12-bit ADC is useful for input monitoring, and eight-channel DMA reduces the processing load associated with continuous audio transfer. The actual signal path still depends on codec selection, sample-rate requirements, clocking, and whether the MCU's 10-bit DAC meets the application's output-quality target.

设计说明
Route all 100 LQFP lands according to the manufacturer package drawing and pin-description table, including every power and ground connection. Place local input and output decoupling capacitors beside their associated pins with short, low-inductance connections. Keep analog sensor inputs away from switching-node and high-current return paths. Because the part offers 256 kB of flash and 64 kB of SRAM, confirm that the selected board footprint also accommodates programming access, boot control, and any crystal or clock circuitry.
Separate quiet analog and digital return paths carefully. The eight-channel 12-bit ADC can be affected by impedance and ground coupling even though its conversion rate is high enough for many control signals. Use short traces from sensor sources to the ADC pins, provide a stable analog reference, and place any input filtering close to the device. Validate the completed layout with an ADC noise test because the 12-bit nominal resolution does not guarantee 12-bit effective system accuracy.
Do not assume that all LPC17xx devices in the 100-pin LQFP family are interchangeable. A candidate can match the 100 MHz core and package while changing memory capacity, Ethernet, USB, CAN, or peripheral-pin assignments. Before substituting LPC1763FBD100, LPC1765FBD100K, LPC1766FBD100, LPC1768FBD100, or LPC1769FBD100K, compare the exact ordering code, power pins, boot behavior, used peripheral pins, clocking, and firmware configuration against the schematic.
Use the Cortex-M3 debug and serial-programming interface during development, but include the correct pull states and boot configuration in the production schematic. For the 100 MHz maximum operating frequency, enforce signal-integrity and power-integrity constraints from the manufacturer timing and electrical specifications. If an external oscillator is used, isolate it from ADC and communication traces. Validate startup, reset release, clock stability, and peripheral timing at both the intended operating voltage and temperature limits.
