Product details
Overview
LPC4078FET180K from NXP Semiconductors is a 32-bit ARM Cortex-M4 microcontroller designed for high-integration embedded control applications, operating at up to 120 MHz with 512 kB flash, 96 kB SRAM, and hardware floating-point unit (FPU). It integrates Ethernet MAC, dual CAN controllers, five UARTs, and 165 GPIO pins, and is deployed in industrial motor drives and programmable logic controllers requiring deterministic real-time response.
For engineers reviewing the LPC4078FET180K datasheet, LPC4078FET180K pinout, LPC4078FET180K application, or LPC4078FET180K equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-chain support details for industrial-grade MCU selection.
Technical Context
The LPC4078FET180K implements an ARM Cortex-M4 core with Harvard architecture, 3-stage pipeline, integrated MPU and NVIC, and optional FPU - enabling single-cycle DSP and SIMD operations. Its multilayer AHB matrix interconnect decouples CPU, DMA, and peripheral masters to eliminate arbitration stalls during concurrent access.
It features dedicated peripherals including a 12-bit ADC with 8-channel multiplexing and 400 kHz sampling, two analog comparators, a 10-bit DAC with timer/DMA support, and a battery-backed RTC with event recorder in its own power domain. The TFBGA180 package omits LCD controller functionality compared to LPC408x variants but retains full EMC, USB Device/Host/OTG, and Ethernet support.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.

FAQ
What is the maximum CPU frequency supported by the LPC4078FET180K?
The LPC4078FET180K supports 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 frequency is sustained across the full industrial temperature range (−40 °C to +85 °C) under 3.3 V supply conditions, and is validated in the official NXP datasheet Rev. 3.
Does the LPC4078FET180K include a hardware floating-point unit (FPU)?
Yes, the LPC4078FET180K integrates a hardware floating-point unit compliant with IEEE 754 single-precision standard. This FPU is part of the ARM Cortex-M4 core and accelerates trigonometric, exponential, and matrix operations essential for motor control and signal processing - confirmed in Section 2.1 of the LPC408X_7X datasheet.
How many CAN interfaces does the LPC4078FET180K support?
The LPC4078FET180K supports two independent CAN 2.0B controllers (CAN0 and CAN1), each with dedicated message RAM, acceptance filtering, and loopback/self-test modes. These interfaces operate concurrently and are accessible via P0[0]/P0[1] and P0[4]/P0[5] pin pairs - as specified in Table 3 of the datasheet.
Is the LPC4078FET180K pin-compatible with the LPC178x family?
Yes, the LPC4078FET180K maintains pin function compatibility with the LPC178x/7x family in the same package variant (TFBGA180), enabling migration paths for existing designs. However, some peripheral signals (e.g., LCD pins) are disabled in LPC4078FET180K due to feature differentiation - per General Description Section 1.
What is the EMC bus width supported by the LPC4078FET180K?
The LPC4078FET180K supports a 16-bit External Memory Controller (EMC) bus width, as documented in Table 2 of the datasheet. This enables direct interfacing with 16-bit NOR flash, SRAM, or PSRAM devices - distinct from the 32-bit EMC option available on LPC4088 variants.
