Accelerate your design success with complimentary RTOS, TCP/IP and USB stacks provided by NXP® MQX™ RTOS. Available on NXP processors, NXP MQX RTOS offer a straightforward API with a modular architecture, making it simple to fine tune custom applications and scalable to fit most requirements. The combination of market-proven NXP MQX RTOS and silicon portfolio provides a streamlined and powerful platform by creating a comprehensive source for hardware, software, tools and services needs.
NXP MQX™ RTOS a full-featured complimentary real-time operating system including the MQX™ Kernel, TCP/IP stack (RTCS), embedded MS-DOS file system (MFS), USB host/device stack, and more. The MQX™ multitasking kernel provides pre-emptive scheduling, fast interrupt response, extensive inter-process communication and synchronization facilities. MQX RTOS includes its own peripheral drivers.
Shipped in millions of products for more than 20 years, NXP MQX™ Software Solutions continue to be a popular choice for embedded designers looking for a rock-solid software platform to enable their deterministic and connected designs.
MQX™ Software Solutions require only a small number of core components, thus enabling memory-efficient applications. However, if more sophisticated application features are what you need, MQX can scale with the addition of optional lightweight or fully-featured components.
Active development of the MQX RTOS continues by NXP with MQX v5. With new commercial licensing, customers can use MQX v5 for designs with the latest Kinetis® and i.MX devices. Compare MQX options and give your feedback below.
Previously released versions of MQX RTOS are now called MQX Classic and include all versions up to MQX v4.x. This software remains available for free download, but does not include support for the latest Kinetis MCUs and i.MX processors. (see MQX v5).
Get ready for the worldwide transition to the next generation of the Internet (IPv6), with the new IPv6 extension for MQX Real Time TCP/IP Communication Suite (RTCS). This optional IPv6 add-on extends the RTCS TCP/IP stack to enable single and dual stack operation (IPv4 + IPv6) to ease your transition to IPv6. Learn more.
