Product details
Overview
LPC4078FET180 from NXP Semiconductors is a 32-bit ARM Cortex-M4 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 512 kB flash, 96 kB SRAM, and 4032 B EEPROM, and supports Ethernet, dual CAN, five UARTs, USB Device/Host/OTG, and LCD (disabled in this variant), targeting industrial automation and motor control systems.
For engineers reviewing the LPC4078FET180 datasheet, LPC4078FET180 pinout, LPC4078FET180 application, or LPC4078FET180 equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-ready procurement details - all grounded in NXP's official LPC408x/7x product data sheet Rev. 3 (2017).
Technical Context
The LPC4078FET180 implements an ARM Cortex-M4 core with hardware floating-point unit (FPU), Memory Protection Unit (MPU), and Nested Vectored Interrupt Controller (NVIC), enabling deterministic execution of DSP-intensive firmware. Its multilayer AHB matrix interconnect decouples CPU, DMA, and peripheral traffic, while the dedicated GPDMA controller supports concurrent transfers across UART, ADC, I2S, SSP, and memory-to-memory paths.
System-level features include a 16-bit External Memory Controller (EMC) interface, RTC with battery-backed registers and event recorder, windowed watchdog timer, CRC engine with DMA offload, and pin-multiplexed I/O supporting 5 V tolerance (except ADC/RTC/VREF pins). The TFBGA180 package omits LCD controller signals versus LQFP208 variants, aligning with cost-optimized industrial HMI and connectivity designs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC4088FET180 | Same TFBGA180 package but includes LCD controller and 32-bit EMC bus (vs. 16-bit in LPC4078FET180); identical flash/SRAM/peripherals otherwise. | Required for designs needing integrated TFT/STN display driving; unnecessary if display is handled externally or omitted. | Select LPC4088FET180 only when LCD interface is mandatory; LPC4078FET180 offers lower cost and reduced pin complexity for non-display applications. |
| LPC4357JBD208 | Dual-core architecture (Cortex-M4 + Cortex-M0), no FPU in M0 core, 264 kB RAM (no EEPROM), different pinout and package (LQFP208), lacks RTC battery domain and event recorder. | Better suited for asymmetric multiprocessing (e.g., M4 for control, M0 for comms), but requires redesign for power management and time-stamped logging. | Choose LPC4357JBD208 only for true dual-core workload partitioning; LPC4078FET180 provides superior RTC integrity and simpler migration from LPC17xx/LPC23xx families. |
Compared with LPC4088FET180, the LPC4078FET180 removes LCD functionality and reduces EMC bus width to 16 bits - lowering BOM cost and simplifying layout where display is external. Against LPC4357JBD208, it retains single-core determinism, battery-backed RTC, and legacy pin compatibility - critical for drop-in upgrades in industrial field equipment.

FAQ
Does the LPC4078FET180 include a hardware floating-point unit (FPU)?
Yes, the LPC4078FET180 integrates a full IEEE 754-compliant hardware FPU within its ARM Cortex-M4 core. This enables single-cycle floating-point arithmetic essential for motor control algorithms, digital filters, and sensor fusion - eliminating reliance on slower software libraries and preserving real-time determinism in the LPC4078FET180 application.
What is the maximum operating frequency of the LPC4078FET180?
The LPC4078FET180 operates at a maximum CPU frequency of 120 MHz, achieved via its on-chip PLL driven by either the 1–25 MHz crystal oscillator or the 12 MHz internal RC oscillator. This clock speed is sustained across the full −40 °C to +85 °C temperature range and 2.4–3.6 V supply, ensuring consistent performance in the LPC4078FET180 design.
How many UART interfaces does the LPC4078FET180 support, and what advanced features do they offer?
The LPC4078FET180 supports five UARTs, each with fractional baud rate generation, 16-byte FIFOs, and DMA capability. UART1 includes full modem control (RTS/CTS/DSR/DTR), USART4 supports IrDA, synchronous mode, and ISO7816-3 smart card protocols, and one UART provides RS-485/EIA-485 driver enable control - making the LPC4078FET180 ideal for industrial serial networking.
Is the LPC4078FET180 pin-compatible with earlier NXP microcontrollers like the LPC178x or LPC23xx families?
Yes, the LPC4078FET180 pinout is explicitly designed for functional replacement of LPC178x/7x and LPC23xx/24xx devices, particularly in TFBGA208 and LQFP208 packages. While the TFBGA180 variant shares peripheral signal mapping, designers must verify ball-to-pin equivalence and update IOCON register configurations - confirming backward compatibility in the LPC4078FET180 migration path.
What power management features does the LPC4078FET180 provide for battery-operated applications?
The LPC4078FET180 offers four reduced-power modes: Sleep, Deep-sleep, Power-down, and Deep power-down. Its RTC resides in a separate power domain with dedicated 3 V battery backup, retaining timekeeping and 20 B of status registers down to 2.1 V. Wake-up is supported via external interrupts, RTC alarms, or PORT0/2 pin events - extending runtime in the LPC4078FET180 battery-powered design.
