Product details
Overview
LPC1778FET180,551 from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller designed for industrial control and connectivity applications requiring high integration, Ethernet/USB support, and low-power operation. It operates at up to 120 MHz, integrates 512 kB flash, 96 kB SRAM (64 kB main + 2×16 kB peripheral), 4032-byte EEPROM, dual CAN, five UARTs, three I²C, three SSP, 12-bit ADC (8-channel), 10-bit DAC, and supports 141 GPIO pins in TFBGA180 package.
For engineers reviewing the LPC1778FET180,551 datasheet, LPC1778FET180,551 pinout, LPC1778FET180,551 application, or LPC1778FET180,551 equivalent, this device serves as a functional replacement for LPC23xx/LPC24xx with enhanced debug (SWD/SWTrace), memory protection (MPU), and multilayer AHB interconnect - critical for real-time deterministic performance in motor control, PLC, and networked embedded systems.
Technical Context
The LPC1778FET180,551 implements a Harvard-architecture ARM Cortex-M3 core with 3-stage pipeline, integrated NVIC, MPU (8 regions), and ETM trace support. Its multilayer AHB matrix enables concurrent CPU, Ethernet, USB, and DMA access without arbitration delay unless contending for the same slave.
Memory subsystem includes flash accelerator for zero-wait-state execution at 120 MHz, split APB bus with write buffering, and dedicated RTC power domain with 20-byte battery-backed registers. The TFBGA180 package omits LCD controller functionality versus LPC1788 variants but retains full EMC (16-bit bus width), SD/MMC, QEI, and motor-control PWM support.

FAQ
What is the maximum operating frequency of the LPC1778FET180,551?
The LPC1778FET180,551 operates at up to 120 MHz using its ARM Cortex-M3 core. This frequency is achieved with the on-chip PLL driven by either the 1–25 MHz crystal oscillator or the 12 MHz internal RC oscillator, and is sustained by the integrated flash accelerator enabling zero-wait-state execution from on-chip flash memory.
Does the LPC1778FET180,551 include an Ethernet MAC?
Yes, the LPC1778FET180,551 includes a full Ethernet MAC with MII/RMII interface and associated DMA controller. This is confirmed in Table 2 of the datasheet, which lists "Y" under the Ethernet column for LPC1778FET180,551 - enabling standalone wired network connectivity without external PHY dependency beyond signal conditioning.
How many GPIO pins are available on the LPC1778FET180,551 in TFBGA180 package?
The LPC1778FET180,551 provides 141 GPIO pins in the TFBGA180 package. This is explicitly stated in Table 2 ("GPIO" column = 141) and differs from the 165 GPIO available in LQFP208 and TFBGA208 variants due to ball count reduction - all 141 pins retain 5 V tolerance and Cortex-M3 bit-banding support.
Is the LCD controller present in the LPC1778FET180,551?
No, the LCD controller is not present in the LPC1778FET180,551. Table 2 confirms "N" under the LCD column for all LPC177x variants, including LPC1778FET180,551. This omission distinguishes the LPC177x family from the LPC178x family (e.g., LPC1788), which includes LCD support in matching packages.
What is the SRAM configuration of the LPC1778FET180,551?
The LPC1778FET180,551 integrates 96 kB of on-chip SRAM: 64 kB main SRAM on the CPU local bus for high-speed code/data access, plus two 16 kB peripheral SRAM blocks accessible via independent paths - enabling concurrent CPU and DMA operations without bus contention, as verified in Section 2 "Features and benefits".
