The NXP LPC1778FBD144K is a 32-bit ARM Cortex-M3 MCU clocked at 120 MHz, with 512 KB of Flash program memory, 96 KB of SRAM, and 4 KB of on-chip EEPROM for parameter storage without external serial memory. It integrates Ethernet MAC and USB OTG controllers, so a connected industrial panel or gateway design can avoid adding separate PHY or bridge ICs.
The Cortex-M3 at 120 MHz handles a real-time control loop alongside a TCP/IP stack and a USB host stack without a second processor.
The LPC1778 family shares pin-compatibility across Flash density options (512 KB / 256 KB) in the same 144-LQFP footprint, so the LPC1776FBD144 (256 KB Flash) or LPC1777FBD144 (512 KB, different peripheral set) are direct alternatives depending on memory and feature requirements.
The ARM Cortex-M3 core runs at 120 MHz.
