Overview

The LPC1769FBD100K is a high-performance ARM Cortex-M3 microcontroller designed for embedded applications requiring high integration and low power consumption. Running at up to 120MHz, it features an Ethernet MAC, USB 2.0 Host/Device/OTG interface, and two CAN 2.0B controllers, making it a robust choice for industrial networking and communication gateways.

Why Choose This Part

The 120MHz clock speed provides a significant performance boost over standard 100MHz Cortex-M3 variants while maintaining a low-power 3.3V operating profile. With 512KB of Flash and 64KB of SRAM, it offers ample memory for RTOS-based applications and complex communication stacks without requiring external memory.

Applications

Industrial Networking
Leverages the integrated Ethernet MAC and dual CAN interfaces for reliable communication in factory automation systems.
Motor Control
Utilizes dedicated Motor Control PWM and 10 32-bit timers to manage complex motion control algorithms.
USB Connectivity
Acts as a USB Host or Device for data logging, human interface devices, or firmware updates via USB OTG.
Communication Gateways
Functions as a bridge between multiple protocols including UART, SPI, I2C, and Ethernet.
