Product details

What this MCU brings to the BOM

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 109 general-purpose I/O lines in a 144-LQFP package give enough headroom for parallel bus interfaces (EBI/EMI), multiple UART/SPI/I²C peripherals, and a motor-control PWM block — all on one chip.

120 MHz core — what it buys you

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.

Frequently asked questions

What is the closest pin-compatible alternative to LPC1778FBD144K?

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.

What is the core speed of LPC1778FBD144K?

The ARM Cortex-M3 core runs at 120 MHz.
