NXP Semiconductors LPC1776FET180,551

Overview

LPC1776FET180,551 from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller designed for embedded control applications requiring high integration, deterministic real-time response, and low-power operation. It operates at up to 120 MHz, integrates 256 kB flash, 64 kB main SRAM, 16 kB peripheral SRAM, 4032-byte EEPROM, dual CAN, USB Device/Host/OTG, five UARTs, and an 8-channel 12-bit ADC - deployed in industrial motor drives and programmable logic controllers.

For engineers reviewing the LPC1776FET180,551 datasheet, LPC1776FET180,551 pinout, LPC1776FET180,551 application, or LPC1776FET180,551 equivalent, this page delivers verified technical context, package-specific I/O count (141 GPIO), TFBGA180 pin mapping, and functional alternatives aligned with NXP's LPC177x family roadmap and documented feature parity.

Technical Context

The LPC1776FET180,551 implements the ARM Cortex-M3 core with a 3-stage pipeline, Harvard architecture (separate instruction/data buses), and integrated Memory Protection Unit (MPU) supporting eight memory regions. Its multilayer AHB matrix enables concurrent access by CPU, USB, and GPDMA without arbitration delay unless accessing the same slave.

It features a dedicated flash accelerator, dual PLLs (one for CPU, one for USB), and a split APB bus with write buffering to reduce CPU stalls. The device supports four reduced-power modes (Sleep, Deep-sleep, Power-down, Deep power-down), with wake-up via RTC, external interrupts on Port 0/2, or NMI - all confirmed in Rev. 5.5 datasheet Section 2.1 and Table 2.

FAQ

What is the maximum operating frequency of the LPC1776FET180,551?

The LPC1776FET180,551 operates at up to 120 MHz CPU frequency, achieved using its on-chip PLL driven by either the 1–25 MHz main crystal oscillator or the internal 12 MHz ±1% RC oscillator. This frequency is sustained across the full industrial temperature range (−40 °C to +85 °C) and 2.4 V–3.6 V supply, as validated in the Rev. 5.5 datasheet Section 2.1 and Table 2.

Does the LPC1776FET180,551 include an Ethernet MAC?

No, the LPC1776FET180,551 does not include an Ethernet MAC. According to Table 2 in the official datasheet, Ethernet is explicitly marked "N" for all LPC177x variants including LPC1776FET180,551. This distinguishes it from LPC178x parts (e.g., LPC1788) which support MII/RMII interfaces. The LPC1776FET180,551 retains dual CAN, USB, and five UARTs for alternative wired connectivity.

How many GPIO pins are available on the LPC1776FET180,551 in TFBGA180 package?

The LPC1776FET180,551 provides 141 general-purpose I/O pins in the TFBGA180 package, as confirmed in Table 2 of the datasheet. This count reflects pin multiplexing limitations specific to the 180-ball variant - fewer than the 165 GPIOs available in LQFP208 or TFBGA208 packages due to reduced ball count and EMC/LCD pin exclusions.

Is the LPC1776FET180,551 pin-compatible with the LPC23xx or LPC24xx families?

Yes, the LPC1776FET180,551 pinout is designed for functional compatibility with LPC23xx and LPC24xx devices, as stated in Section 1.1 of the datasheet. However, this refers to shared peripheral pin assignments (e.g., UART, CAN, I²C locations), not full pin-for-pin equivalence - differences in power domains, reset behavior, and peripheral enable registers require firmware adaptation despite physical layout similarity.

What power modes does the LPC1776FET180,551 support, and how is wake-up managed?

The LPC1776FET180,551 supports four reduced-power modes: Sleep, Deep-sleep, Power-down, and Deep power-down. Wake-up is handled by the Wake-up Interrupt Controller (WIC), enabling CPU restart from any priority interrupt - including RTC alarm, external pins on Port 0/2, CAN activity, or NMI. Brownout detection and POR circuitry ensure reliable boot across voltage transients, per Section 2.12 of the datasheet.
