Product details
Overview
LPC4078FET208 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 dual CAN interfaces. It integrates Ethernet MAC, USB Device/Host/OTG, five UARTs, and a 12-bit ADC - deployed in industrial motor drives and networked HVAC controllers.
For engineers reviewing the LPC4078FET208 datasheet, LPC4078FET208 pinout, LPC4078FET208 application, or LPC4078FET208 equivalent, key selection criteria include TFBGA208 package compatibility, absence of LCD controller (vs. LPC4088), FPU availability, EMC bus width, and CAN channel count for real-time fieldbus integration.
Technical Context
The LPC4078FET208 implements a Harvard-architecture ARM Cortex-M4 core with 3-stage pipeline, hardware floating-point unit (FPU), Memory Protection Unit (MPU), and Nested Vectored Interrupt Controller (NVIC). Its multilayer AHB matrix enables concurrent CPU and DMA access without arbitration delay, while dedicated APB bridges reduce stalls between peripherals and system bus.
Peripheral subsystems include a General Purpose DMA controller supporting UART, ADC, DAC, I2S, and SSP; an RTC with battery-backed registers and event recorder; and a CRC engine usable with DMA for offload checksum computation. The device supports four low-power modes - Sleep, Deep-sleep, Power-down, and Deep power-down - with wake-up via PORT0/2 pins, RTC, or external interrupts.

FAQ
Does LPC4078FET208 include a hardware floating-point unit (FPU)?
Yes, the LPC4078FET208 integrates a hardware floating-point unit compliant with IEEE-754 single-precision format. This FPU accelerates trigonometric, exponential, and matrix operations essential for motor control algorithms and digital signal processing - eliminating software emulation latency and improving real-time loop performance in the LPC4078FET208.
What is the maximum operating frequency of LPC4078FET208?
The LPC4078FET208 operates at a maximum CPU frequency of 120 MHz. This is achieved using the on-chip PLL driven by either the internal 12 MHz RC oscillator (trimmed to ±1 %) or an external crystal (1–25 MHz). The flash accelerator ensures zero-wait-state execution at this speed, maintaining deterministic timing in the LPC4078FET208.
How many CAN interfaces does LPC4078FET208 support?
The LPC4078FET208 supports two independent CAN 2.0B controllers. Each provides full message filtering, transmit/receive FIFOs, and error handling - enabling redundant communication paths or multi-network architectures in industrial automation and automotive diagnostics. This dual-CAN capability is confirmed in Table 2 of the official datasheet for the LPC4078FET208.
Is the LCD controller present in LPC4078FET208?
No, the LCD controller is disabled in the LPC4078FET208 variant. As shown in Table 2 of the datasheet, "LCD" is marked "no" for all LPC4078 part numbers, including LPC4078FET208. This distinguishes it from the LPC4088 family, which includes full STN/TFT support - making the LPC4078FET208 appropriate for headless or externally driven display applications.
What package type is used for LPC4078FET208?
The LPC4078FET208 uses a TFBGA208 package: plastic thin fine-pitch ball grid array with 208 solder balls, body size 15 × 15 × 0.7 mm. This high-density package supports 165 GPIOs and is optimized for compact industrial PCB layouts - matching pinout compatibility with LQFP208 variants while reducing footprint area compared to LPC4078FBD208.
