NXP Semiconductors LPC4088FET208,551

Overview

LPC4088FET208 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 integrated Ethernet, USB Device/Host/OTG, LCD controller, and dual CAN interfaces. It targets industrial automation, motor drive, and communications infrastructure requiring deterministic real-time performance and low-power operation.

For engineers reviewing the LPC4088FET208 datasheet, LPC4088FET208 pinout, LPC4088FET208 application, or LPC4088FET208 equivalent, this page delivers verified technical context, validated pin functions for TFBGA208, confirmed peripheral integration (EMC, SPIFI, GPDMA), and precise alternative selection guidance aligned with NXP's documented functional replacement strategy.

Technical Context

The LPC4088FET208 implements an ARM Cortex-M4 core with hardware floating-point unit (FPU), Memory Protection Unit (MPU), and Nested Vectored Interrupt Controller (NVIC), executing from on-chip flash accelerated by a dedicated flash accelerator. Its multilayer AHB matrix interconnect enables concurrent CPU and General Purpose DMA (GPDMA) access without arbitration delay to peripherals including Ethernet MAC, USB controllers, and LCD.

System-level features include a dedicated RTC power domain with battery-backed registers and event recorder, dual PLLs (one for CPU, one for USB), and a versatile pin-muxing architecture supporting up to 165 GPIOs across multiple packages. The TFBGA208 variant retains full peripheral complement-including 32-bit EMC bus width, LCD support, and dual CAN-matching the LQFP208 pin-compatible family member.

FAQ

Does LPC4088FET208 include a hardware floating-point unit (FPU)?

Yes, the LPC4088FET208 integrates a hardware floating-point unit (FPU) as part of its ARM Cortex-M4 core. This enables efficient execution of single-precision floating-point arithmetic required for digital signal processing, motor control algorithms, and sensor fusion tasks without software emulation overhead. The FPU is present across all LPC4088 variants, including LPC4088FET208.

What is the maximum operating frequency of LPC4088FET208?

The LPC4088FET208 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 clock speed is sustained across the full industrial temperature range (−40 °C to +85 °C) and 3.3 V supply, enabling high-throughput real-time processing in demanding applications.

How many CAN interfaces does LPC4088FET208 support?

The LPC4088FET208 supports two independent CAN 2.0B controllers (CAN0 and CAN1), each with dedicated transmit and receive pins (e.g., P0[0]/P0[1] for CAN1). Both controllers feature hardware message filtering, FIFO buffering, and programmable bit timing, making LPC4088FET208 suitable for multi-node industrial networks or automotive after-market systems requiring protocol redundancy.

Is LPC4088FET208 pin-compatible with other LPC408x family members?

Yes, the LPC4088FET208 shares identical pin functions and peripheral mapping with other 208-pin variants in the LPC408x/7x family, including LPC4088FBD208 (LQFP208) and LPC4078FET208 (TFBGA208). Pin compatibility extends to signal names, reset states, and multiplexing options per the IOCON register, enabling direct substitution in compatible layouts.

What peripheral interfaces are supported by the External Memory Controller (EMC) in LPC4088FET208?

The External Memory Controller (EMC) in LPC4088FET208 supports asynchronous static memory devices (SRAM, ROM, NOR flash) and synchronous dynamic memories including single-data-rate SDRAM. It provides a configurable 32-bit data bus width, programmable timing parameters, and dedicated address/control signals-enabling expansion of program/data memory for HMI, data logging, or firmware update storage.
