Product details
Overview
LPC4078FET208 from NXP Semiconductors is a 32-bit ARM Cortex-M4 microcontroller designed for industrial and 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, dual CAN interfaces, Ethernet MAC with MII/RMII, USB 2.0 full-speed device/host/OTG, five UARTs, and a 12-bit ADC - deployed in motor drive and PLC systems.
For engineers reviewing the LPC4078FET208 datasheet, LPC4078FET208 pinout, LPC4078FET208 application, or LPC4078FET208 equivalent, key selection considerations include its TFBGA208 package with 208-ball layout, absence of LCD controller (vs. LPC4088), hardware FPU availability, EMC support, and pin-compatible migration path from LPC178x/7x and LPC24xx families.
Technical Context
The LPC4078FET208 implements an ARM Cortex-M4 core with Harvard architecture, 3-stage pipeline, integrated MPU, NVIC, and optional hardware floating-point unit - enabling deterministic DSP operations and real-time interrupt handling. Its multilayer AHB matrix interconnect decouples CPU, DMA, and peripheral masters to eliminate arbitration stalls during concurrent access.
System-level features include dedicated RTC power domain with 20-byte battery-backed registers, event recorder synchronized to RTC clock, windowed watchdog timer with internal oscillator, and CRC engine supporting three standard polynomials - all accessible via GPDMA without CPU intervention for efficient data integrity verification.

FAQ
Does LPC4078FET208 include a hardware floating-point unit (FPU)?
Yes, the LPC4078FET208 integrates an ARM Cortex-M4 core with optional hardware floating-point unit (FPU). The FPU is present in this variant and supports IEEE 754 single-precision operations, accelerating mathematical computations required for motor control algorithms and digital signal processing tasks within the LPC4078FET208.
What is the maximum operating frequency of LPC4078FET208?
The LPC4078FET208 operates at a maximum CPU frequency of 120 MHz. This speed is achieved using the on-chip PLL driven by either the main oscillator (1–25 MHz crystal) or the internal 12 MHz RC oscillator, with flash accelerator enabling zero-wait-state execution from on-chip flash memory.
How many UART interfaces does LPC4078FET208 support?
The LPC4078FET208 supports five UART interfaces. UART0 through UART3 and USART4 each provide fractional baud rate generation, internal FIFO, DMA support, and RS-485/EIA-485 capability. USART4 additionally supports IrDA, synchronous mode, and ISO7816-3 smart card protocols - all implemented natively within the LPC4078FET208.
Is LPC4078FET208 pin-compatible with earlier NXP microcontrollers?
Yes, the LPC4078FET208 maintains pin function compatibility with the LPC178x/7x and LPC24xx/23xx families in the same package variant (e.g., LQFP208 or TFBGA208). This allows direct migration paths for existing designs, preserving PCB layout while upgrading to Cortex-M4 performance, dual CAN, and Ethernet capabilities in the LPC4078FET208.
Does LPC4078FET208 support external memory expansion?
Yes, the LPC4078FET208 includes an External Memory Controller (EMC) supporting asynchronous static memories (SRAM, ROM, NOR flash) and dynamic memories including single-data-rate SDRAM. In TFBGA208 package, it provides a 32-bit data bus width - enabling high-bandwidth off-chip memory access directly managed by the LPC4078FET208 without external glue logic.
