Overview

The LPC1768FBD100Y is an NXP ARM Cortex-M3 microcontroller running up to 100 MHz with 512 KB of on-chip flash and 64 KB of RAM in a 100-pin LQFP package. It provides a broad set of connectivity and peripheral options (Ethernet, USB OTG, CAN, I2C, SPI, UART, I2S, PWM and more) and around 70 general-purpose I/O pins. The device targets applications that need moderate CPU performance together with rich networking and real-time I/O.

Why Choose This Part

This MCU combines a full-featured 32-bit Cortex-M3 core at up to 100 MHz with a large on-chip flash (512 KB) and 64 KB of SRAM, giving room for complex firmware and network stacks. Hardware peripherals include Ethernet MAC, USB OTG, CAN, multiple UART/SPI/I2C, timers with PWM and DMA, which reduces external component count for connected and real-time designs. The 100-pin package provides many accessible I/O lines useful for sensor-dense or multi-peripheral applications.

Applications

Industrial motor drives and motion control
Multiple PWM channels, DMA and timer peripherals make it well suited for controlling motors and closed-loop motion systems.
Ethernet- and USB-enabled gateways
Integrated Ethernet MAC and USB OTG allow use as a network gateway, protocol converter, or data-logger with host/device USB support.
Robotics controllers
Plenty of GPIO, serial buses (CAN, UART, SPI, I2C) and real-time timers support sensor fusion, actuator control and inter-module comms in robots.
Embedded networking and CAN bus nodes
Built-in CAN and Ethernet support makes it a solid choice for vehicle or industrial networked nodes.
Data acquisition and signal pre-processing
On-chip DMA, ADCs and plenty of I/O let it collect and preprocess sensor data before passing it to higher-level systems.

Getting Started

Common toolchains include Arm Keil MDK, GCC Arm toolchain (arm-none-eabi-gcc) and NXP software support/SDKs. Development boards and starter kits based on the LPC1768 (mbed-style boards and vendor eval boards) simplify early prototyping; program and debug over SWD/JTAG using CMSIS-DAP, J-Link or similar probes. Use a regulated 3.3 V supply, good decoupling on VDD pins and follow NXP application notes for reset, crystal and USB/Ethernet interface designs.
