Product details
Overview
LPC4078FBD144 from NXP Semiconductors is a 32-bit ARM Cortex-M4 microcontroller designed for high-integration embedded control applications, featuring 512 kB flash, 96 kB SRAM, Ethernet MAC with MII/RMII, USB 2.0 full-speed device/host/OTG, and five UARTs. It operates up to 120 MHz and supports CAN 2.0B dual-channel communication, making it suitable for industrial motor drives and networked automation controllers.
For engineers reviewing the LPC4078FBD144 datasheet, LPC4078FBD144 pinout, LPC4078FBD144 application, or LPC4078FBD144 equivalent, this page delivers verified technical context, LQFP144 package mapping, confirmed peripheral set (no LCD), real-time clock with battery-backed event recorder, and validated alternative options for migration from LPC17xx or LPC24xx platforms.
Technical Context
The LPC4078FBD144 implements an ARM Cortex-M4 core with hardware floating-point unit (FPU), Memory Protection Unit (MPU), and Nested Vectored Interrupt Controller (NVIC), executing at up to 120 MHz via dual PLL architecture-one for CPU and one dedicated for USB. Its multilayer AHB matrix interconnect enables concurrent CPU and DMA access without arbitration delay unless contending for the same slave.
Peripheral integration includes a General Purpose DMA controller supporting SSP, I2C, UART, ADC, DAC, timers, and GPIO; a CRC engine usable with DMA for zero-CPU overhead checksumming; and a windowed watchdog timer with dedicated oscillator. Unlike LPC4088 variants, LPC4078FBD144 excludes LCD controller but retains full Ethernet, USB, CAN, SD/MMC, and QEI functionality.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC1788FBD208 | No FPU; Cortex-M3 core; max 100 MHz; 512 kB flash, 64 kB SRAM; includes LCD controller; no USB OTG support. | Lacks hardware floating-point and USB OTG; supports STN/TFT displays directly - suited for display-centric HMI but not compute-intensive control. | Select LPC1788FBD208 only if display interface is required and FPU is unnecessary; verify layout compatibility due to LQFP208 vs LQFP144 footprint. |
| LPC4357JBD208 | Dual-core (Cortex-M4 + Cortex-M0); 264 kB SRAM; no on-chip flash (uses external SPIFI); includes Ethernet, USB HS/FS, CAN, and LCD - higher performance but requires external memory boot. | Requires external flash boot and more complex memory mapping; better for asymmetric multiprocessing but increases BOM and design complexity. | Choose LPC4357JBD208 when dual-core task partitioning (e.g., M4 for control, M0 for comms) justifies external flash dependency and larger package. |
Compared with LPC1788FBD208 and LPC4357JBD208, the LPC4078FBD144 uniquely balances Cortex-M4 FPU performance, integrated 512 kB flash, LQFP144 compactness, and full USB/Ethernet/CAN connectivity - making it optimal for space-constrained industrial controllers requiring floating-point math and fieldbus interoperability.

FAQ
Does LPC4078FBD144 include a hardware floating-point unit (FPU)?
Yes, the LPC4078FBD144 integrates a single-precision IEEE 754 hardware FPU as part of its ARM Cortex-M4 core. This enables efficient execution of floating-point arithmetic without software emulation, critical for real-time control algorithms, sensor fusion, and digital signal processing tasks within the LPC4078FBD144's 120 MHz operating envelope.
What is the maximum operating frequency of LPC4078FBD144?
The LPC4078FBD144 operates at a maximum CPU frequency of 120 MHz, achieved via its on-chip PLL driven by either the main oscillator (1–25 MHz crystal) or the internal 12 MHz 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 voltage.
Does LPC4078FBD144 support LCD display interfaces?
No, the LPC4078FBD144 does not include an LCD controller. Per Table 2 of the datasheet, LCD support is explicitly marked "no" for all LPC4078 variants, including LPC4078FBD144. In contrast, LPC4088 variants retain LCD functionality. Designers requiring display support must select an LPC4088 variant or add external display controller logic.
How many UARTs does LPC4078FBD144 provide, and do they support RS-485?
The LPC4078FBD144 features five UARTs, all supporting fractional baud rate generation, internal FIFO, and DMA. UART1 and UART4 include dedicated RS-485/EIA-485 support: UART1 has full modem control I/O and configurable RTS as output enable, while UART4 provides OE (output enable) signal (U4_OE) and synchronous mode - enabling robust multi-drop industrial serial communication.
What package type and pin count does LPC4078FBD144 use?
LPC4078FBD144 uses a plastic low-profile quad flat package (LQFP144) with 144 leads, body dimensions 20 × 20 × 1.4 mm (SOT486-1). It provides access to up to 165 GPIO pins across four 32-bit ports, with 5V-tolerant digital I/O (excluding analog and power pins), and supports pin function multiplexing via the Pin Connect Block.
