MPN： LPC1768FET100Y ✓ 啟用中LPC1768FET100Y 概覽
An Arm Cortex-M3 microcontroller is a 32-bit embedded processor built around the ARMv7-M architecture and the Cortex-M3 profile. This product type sits within the hierarchy of embedded processor, microcontroller, and semiconductor. Unlike a general-purpose application processor, a Cortex-M3 MCU combines a processor core with memory and peripherals in one device, allowing compact embedded systems to execute control firmware, acquire analog data, exchange digital information, and drive timers or PWM outputs without a separate external processor.
The LPC1768FET100Y provides 512 kB of flash for firmware and 64 kB of data memory for working storage. Its four UART interfaces support serial communications, while the two CAN channels are suited to robust controller-area-network communication. Three SSP/SPI interfaces, three I2C interfaces, and I2S support expand the range of sensors, displays, storage devices, audio peripherals, and bus devices that can be connected. The 8-channel 12-bit ADC supports multi-channel analog measurements, while the 10-bit DAC provides an analog output function.
Peripheral integration reduces the component count in connected embedded equipment. The Ethernet MAC supports network-oriented designs, while the combined USB Device, Host, and OTG capability allows one controller architecture to serve peripheral, host, and dual-role applications. An 8-channel DMA controller can transfer data between memory and peripherals with limited processor intervention, which is useful when data movement must remain deterministic while the core executes control logic. Motor-control PWM supports timing and power-control functions in embedded systems.
Typical applications include industrial automation and factory control, networked sensor gateways, CAN-based equipment controllers, USB-connected data acquisition units, communications equipment, and compact motor-control systems. The 100-TFBGA package is particularly relevant to space-constrained products where a high pin count and integrated communications peripherals are needed. PCB designers should assess via access, exposed-pad thermal requirements, and assembly capability before committing the design to this fine-pitch package.
Before schematic capture, use the manufacturer pin-description and package-information tables to assign power, ground, clock, reset, analog, and communications signals. Confirm the external crystal or clock arrangement, decoupling requirements, Ethernet PHY interface, USB routing, and programming/debug access in the manufacturer documentation. The BGA land pattern also requires careful escape routing and via planning to preserve signal integrity and manufacturing yield.
This page consolidates the exact device identity, interface inventory, package information, sourcing path, and application guidance for engineers evaluating the LPC1768FET100Y. It also distinguishes verified drop-in options from broader functional alternatives, helping teams make a footprint, memory, peripheral, and firmware-migration decision before committing an embedded design to production.

典型應用
LPC1768FET100Y 適用於 6 應用s: Industrial Automation Controllers, Ethernet-Connected Sensor Gateways, USB Data-Acquisition Equipment, CAN-Based Equipment Control, Communications and Network Control, Embedded Motor-Control Systems.
Industrial Automation Controllers
The LPC1768FET100Y fits industrial automation controllers that require deterministic control, communications, and analog measurement in one device. Its 100 MHz Arm Cortex-M3 core provides processing headroom, while four UARTs, two CAN channels, three SSP/SPI interfaces, and three I2C interfaces support sensors, actuators, gateways, and service equipment. The 8-channel 12-bit ADC supports multichannel process monitoring, and motor-control PWM assists timing and power-control functions. Using one MCU simplifies the hardware architecture, although industrial designs must implement suitable protection, isolation, grounding, and fault-handling measures around external interfaces.
推薦
Ethernet-Connected Sensor Gateways
The LPC1768FET100Y is well suited to an Ethernet-connected sensor gateway because it combines an Ethernet MAC with three serial buses and extensive analog acquisition. The 100 MHz Cortex-M3 core can aggregate readings and manage communications, while the 8-channel 12-bit ADC accepts multiple analog inputs from industrial or environmental sensors. Its 64 kB of data memory supports runtime working storage, and the 8-channel DMA controller can reduce processor involvement during data transfers. An external Ethernet PHY is still required, and the PCB must preserve the high-speed integrity of the Ethernet interface.
推薦
USB Data-Acquisition Equipment
The LPC1768FET100Y supports USB data-acquisition equipment through its integrated USB Device, Host, and OTG capability. Its 8-channel 12-bit ADC can sample multiple analog inputs, and the 8-channel DMA controller can move captured data efficiently while the 100 MHz core performs filtering, scaling, and protocol handling. The 512 kB of flash provides substantial firmware space, while 64 kB of data memory can support acquisition buffers and control structures. Designers should budget USB routing and impedance-control space, provide stable clocking and decoupling, and verify enumeration behavior for the intended host or peripheral role.
推薦
CAN-Based Equipment Control
The LPC1768FET100Y is appropriate for CAN-based equipment control because it includes two CAN channels alongside four UARTs and three SSP/SPI interfaces. Its 100 MHz Cortex-M3 core can execute control algorithms and service multiple communications tasks, while the 8-channel 12-bit ADC monitors equipment condition and the 10-bit DAC can support analog control outputs. The two CAN controllers make it practical to divide traffic across separate buses or isolate high-priority and diagnostic traffic. A production design still needs an appropriate CAN physical-layer transceiver, protection components, common-mode strategy, and validated termination.
推薦
Communications and Network Control
The LPC1768FET100Y can act as a compact communications controller because it combines Ethernet MAC, USB Device, Host, and OTG, four UARTs, three SSP/SPI interfaces, three I2C interfaces, and I2S. This breadth allows one processor to supervise serial links, storage, audio peripherals, and network traffic without depending on a separate communications processor. The 100 MHz core and 8-channel DMA controller are useful for protocol processing and concurrent data movement, while 512 kB of flash supports a substantial firmware image. Deployment quality depends on careful clock planning, peripheral pin multiplexing, Ethernet impedance control, and firmware resource budgeting.
推薦
Embedded Motor-Control Systems
The LPC1768FET100Y supports embedded motor-control systems by combining a 100 MHz Cortex-M3 core with motor-control PWM, an 8-channel 12-bit ADC, and a 10-bit DAC. PWM outputs can generate commanded motor timing, while ADC channels can monitor position, current, temperature, or other control variables. The 64 kB of data memory supports control state and working buffers, while four UARTs and two CAN channels enable configuration, diagnostics, and network coordination. The MCU should be used with suitable gate drivers, power stages, current sensing, and protection; its internal analog and PWM resources do not replace the external power-conversion hardware.

設計說明
Plan the 100-TFBGA layout from the official land pattern rather than from a generic BGA drawing. Maintain the manufacturer's ball-pitch and pad geometry, place decoupling capacitors close to the associated power balls, and provide adequate escape-routing vias between the fine-pitch device and the surrounding PCB layers. Ethernet and USB traces require controlled impedance and an uninterrupted return path. Review assembly yield, inspection access, and thermal-via placement before releasing the board for production.
Confirm the LPC1768FET100Y supply-voltage limits and external clock requirements in the NXP datasheet before fixing the power tree. Apply the manufacturer-recommended decoupling network at each relevant supply ball and account for the current required by the 100 MHz core and enabled peripherals. Isolate analog and digital return paths where the layout permits, and define power-up and reset behavior so peripheral interfaces do not drive external buses before the MCU reaches a valid operating state.
Give Ethernet, USB, and high-speed clock signals continuous reference planes and verify controlled-impedance routing through the BGA escape region. Keep crystal or clock traces short, route them away from switching nodes and noisy digital returns, and follow the manufacturer guidance for adjacent decoupling and guard routing. Although the MCU provides USB Device, Host, OTG, and Ethernet MAC functionality, connector launch geometry, return-path continuity, and external PHY layout remain critical to reliable operation.
Do not treat a similar Cortex-M3 processor as an automatic drop-in replacement. Verify every BGA assignment, supply ball, clock pin, reset connection, debug interface, and multiplexed peripheral signal against the exact datasheet. For firmware migration, review startup code, linker placement, interrupt vectors, peripheral base addresses, pin-mux registers, and driver APIs. The LPC1768FET100Y supports USB in Device, Host, and OTG roles, but each role requires the correct external connection and firmware configuration.
