Product Overview

LPC1768FBD100K is a high-performance microcontroller (MCU) from NXP’s LPC17xx Series, based on the ARM® Cortex-M3 core, designed for scenarios requiring high integration and reliability such as industrial control, smart meters, security equipment, and consumer electronics. This product supports a maximum clock frequency of 100 MHz, integrates 512 kB programmable Flash and 64 kB SRAM, and is equipped with Ethernet MAC, USB 2.0 full-function interface, multi-channel analog modules, and rich industrial-grade peripherals. Adopting a 100-pin LQFP package (14mm×14mm×1.4mm), it operates within a voltage range of 2.4-3.6 V and a temperature range of -40°C to 85°C, perfectly suitable for complex embedded applications such as industrial networking, motor control, and smart metering. As the core model of the LPC17xx Series, its balanced performance, comprehensive function coverage, and mature ecosystem support make it an optimal choice for mid-to-high-end 32-bit MCUs.

Key Features
