The LPC microcontrollers ecosystem

We get you up and developing in minutes, not hours, and on world-class development platforms. The LPC software ecosystem offers advanced yet low-cost ways to evaluate and develop with LPC MCUs and, because the entire Cortex-M portfolio works with a single MCU toolchain, you can use a familiar set of tools no matter which LPC family you choose. Our software libraries, in combination with world class solutions from our software and hardware platform partners, save you time and free you to focus your attention on what sets your product apart.

Development tools

Toolchains are the cornerstone of MCU software development, and we recognize that one size does not fit all needs. NXP’s tool offerings are complemented by our third-party partnerships to help us tailor our offerings for specific applications, so you always get the best options for developing and debugging software on your chosen LPC MCU.

LPCOpen software platform

LPCOpen is a comprehensive set of RTOS-agnostic, LPC family-specific libraries that give software developers quick access to key product features. It includes chip- and board-level device drivers, plus protocol stacks for TCP/IP (LWIP) and USB devices and hosts. Two graphics libraries (SWIM and SEGGER emWin), let you choose to minimize footprint or implement full-featured graphics. Available as a free download from, LPCOpen includes examples using FreeRTOS and Micrium μCOS-III for most devices, and lets you build common APIs with Keil, IAR, and LPCXpresso toolchains.

LPCXpresso IDE

This powerful, highly-integrated software development environment provides everything needed to develop high-quality applications. Building on its Eclipse foundation, the free edition of LPCXpresso adds many enhancements that simplify development. It features the industry-standard GNU toolchain, and lets you use a proprietary C library based on the standard Newlib library. The Pro edition supports unlimited code downloads and includes one year of email-based support from our own LPCXpresso experts.

For further information click here.

LPCXpresso development boards

Designed for rapid prototyping and evaluation, these inexpensive boards work with the LPCXpresso IDE. Debug can be done using the integrated probe or an external one, and each board can act as a debug probe for other targets. The latest LPCXpresso boards include Arduino Uno and Pmod™ connectors and free pads for easy prototyping.
