LPC2388FBD144K - 72MHz ARM7 MCU, 512KB Flash | NXP
料号： LPC2388FBD144K ✓ 量产中LPC2388FBD144K 概述
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals into one device. The LPC2388 belongs to the ARM7 microcontroller family and the LPC2300 series, positioning it between a general-purpose embedded CPU and a highly integrated system-on-chip. It is designed for industrial equipment, communications equipment, data acquisition, control panels, and USB- or Ethernet-connected products.
Key features include 512 KB of high-speed embedded flash with ISP and IAP support, 98 KB of SRAM, a 128-bit memory interface, and an accelerator architecture that supports 32-bit code execution at the maximum clock rate. Communication interfaces include Ethernet MAC, USB 2.0 Device, Host and OTG, four UARTs, two CAN channels, three SSP/SPI interfaces, three I2C interfaces, and I2S. An 8-channel 10-bit ADC and 10-bit DAC support analog measurement and output functions.
The 72 MHz ARM7TDMI-S core uses a 32-bit architecture, while a 16-bit Thumb instruction set supports compact code. A 128-bit external memory interface and accelerator architecture improve code execution and interrupt-service performance. The integrated Ethernet MAC, USB controller, CAN channels, DMA, and low-power Real-Time Clock reduce the need for external interface components in connected industrial designs.
Typical applications include Ethernet-connected industrial controllers, USB data-acquisition equipment, CAN-based automation systems, communications gateways, medical instrumentation, and embedded control systems. The combination of local flash, SRAM, analog conversion, and multiple serial interfaces supports standalone control as well as networked data collection.
Designers should assign every pin by consulting the LPC2388 manufacturer datasheet, especially the multiplexing and startup functions shared by boundary, Ethernet, USB, and analog pins. The 144-LQFP footprint requires careful escape routing, while external crystal, reset, and power-supply arrangements must follow the recommended application circuit.
This page consolidates the key MCU specifications, interface capabilities, application guidance, and available sourcing path into one engineering-focused reference. It also distinguishes the exact LPC2388FBD144K ordering code from related LPC2388 variants to reduce procurement and footprint-selection errors.

典型应用
LPC2388FBD144K 适用于 6 应用s: Ethernet-Connected Industrial Control, USB Data-Acquisition Equipment, CAN-Based Automation Controller, Medical Instrument Control Board, Communications Gateway, USB-Checked Test and Control Module.
Ethernet-Connected Industrial Control
The LPC2388FBD144K fits Ethernet-connected industrial controllers because its 72 MHz ARM7TDMI-S core handles control logic while the integrated Ethernet MAC supports network communication. With 512 KB of embedded flash, 98 KB of SRAM, four UARTs, three SSP/SPI interfaces, and three I2C interfaces, the device can connect sensors, local I/O, and operator equipment without requiring several separate interface ICs. The 128-bit memory interface and accelerator architecture support efficient 32-bit execution, while DMA helps transfer data with less processor involvement. The 144-LQFP 20 x 20 mm package remains practical for industrial boards that require many pins and a surface-mount assembly process.
推荐
USB Data-Acquisition Equipment
The LPC2388FBD144K is well suited to USB data-acquisition equipment because it combines USB 2.0 Device, Host and OTG with an 8-channel 10-bit ADC and a 10-bit DAC. The 512 KB of embedded flash can hold application firmware and configuration data, while 98 KB of SRAM supports sampling buffers and protocol handling. Its four UARTs and three SPI/SSP channels allow expansion with sensors, memory, and external converters. DMA can move sampled data efficiently, and the 72 MHz core provides capacity for signal conditioning calculations and a responsive USB control interface. Use the NXP recommended layout for USB routing, power delivery, and decoupling.
推荐
CAN-Based Automation Controller
The LPC2388FBD144K supports CAN-based automation systems through its two integrated CAN channels and extensive serial peripherals. A single controller can manage machine-state logic, collect sensor data through I2C or SPI, and communicate over Ethernet or USB without duplicating interface hardware. The 72 MHz ARM7TDMI-S processor allows deterministic control tasks to coexist with communications, and the 128-bit memory interface and accelerator architecture improve interrupt-service performance. The 98 KB of SRAM is useful for buffering protocol frames and diagnostic information, while 512 KB of flash supports firmware, calibration data, and communication stacks.
推荐
Medical Instrument Control Board
The LPC2388FBD144K can serve as the central controller in medical instrumentation when the system requires deterministic local control and multiple communication paths. Its integrated 10-bit ADC and DAC support analog measurement and output functions, while USB, Ethernet, UART, SPI, and I2C interfaces connect to sensors, displays, storage, and service ports. The 512 KB of embedded flash accommodates embedded firmware, and the 98 KB of SRAM supports working buffers and protocol stacks. The 72 MHz core provides performance for control loops and foreground processing. Because the device is not established as an automotive-qualified part, medical use should follow the applicable risk, quality, and electrical-validation process for the finished equipment.
推荐
Communications Gateway
The LPC2388FBD144K is suitable for a communications gateway that must bridge industrial or embedded protocols. Two CAN channels, four UARTs, three SSP/SPI interfaces, three I2C interfaces, USB 2.0, and Ethernet MAC provide several paths for protocol conversion and local device management. The 72 MHz ARM7 core can manage concurrent protocol tasks, while DMA and the 128-bit memory interface support efficient data movement. Local flash and SRAM allow the gateway to retain firmware and use buffers without an external memory component in many configurations. The 144-LQFP package exposes the many required I/O functions while supporting standard surface-mount manufacturing.
推荐
USB-Checked Test and Control Module
The LPC2388FBD144K fits compact test and control modules that need a host processor, data conversion, and flexible communications. USB 2.0 Device, Host and OTG support direct PC connectivity or peripheral control, and the 10-bit ADC and DAC support analog stimulus and measurement functions. Four UARTs and three SPI channels allow connection to instruments or fixture hardware. At 72 MHz, the ARM7TDMI-S core can execute control sequences and protocol handling, while 98 KB of SRAM provides useful working memory. Its active manufacturer status supports lifecycle planning for existing industrial test equipment, although the exact temperature grade and any required regulatory qualifications must be confirmed for the finished system.

设计说明
Assign boundary, Ethernet, USB, and analog functions from the LPC2388 manufacturer datasheet before laying out the 144-LQFP PCB. Several pins serve multiple functions, so fixing the required peripheral mix early prevents late layer changes. Keep the supported USB and Ethernet routes short, preserve the reference return paths, and follow the manufacturer footprint and land-pattern recommendations.
Design the 3.3 V supply and decoupling around the recommended LPC2388 application circuit. Place high-frequency bypass capacitors close to the relevant supply pins, verify the regulator's transient response against the selected clock and I/O activity, and provide clean analog grounding where the ADC and DAC are used. Confirm absolute maximum and operating voltages in the datasheet before finalizing the power tree.
Treat clock, reset, and high-speed USB traces as layout-sensitive nets. Route the crystal or clock connection with short traces away from Ethernet and switching nodes, use the documented reset network, and avoid routing interrupt-heavy interfaces beneath noisy power or digital activity. The 144-LQFP footprint demands deliberate escape routing, so check every multilayer transition before fabrication.
Do not substitute a Cortex-M or other similarly positioned MCU solely because it offers comparable clock speed. The LPC2388FBD144K relies on ARM7 memory mapping, startup behavior, peripheral registers, and multiplexed pin functions. A replacement is safe only after checking the complete pin list, package, interrupt configuration, clock tree, memory map, peripheral equivalents, and firmware requirements.
