emNet is an industry-leading dual IPv4/IPv6 TCP/IP stack for embedded systems.

Designed from the ground up for embedded systems, it is renowned for its high-performance and small memory footprint while still providing flexibility and extensibility. It is at the heart of many industrial and IoT applications and provides support for a wide variety of standard protocols.

  • Easy to use
  • Wide variety of upper layer protocols available
  • Standard socket API for user applications
  • Zero-copy supported for ultra-high performance and efficiency
  • Simple compile-time configuration
  • Extensive runtime configuration
  • IEEE 1588 PTP precision time protocol support
  • Works with or without RTOS
  • Outstanding documentation

emNet (formerly embOS/IP) has proven its value over the years in many customer products and in our own products such as J-Link PRO, Flasher PRO, Flasher ATE, Flasher Secure, Flasher ARM and Flasher 5 PRO. emNet is more than an IP stack, it is a complete and modern networking software to meet the requirements of all network related applications including the Internet of Things. emNet works best with an RTOS. Naturally SEGGER recommends the use of embOS, but if for any reason the customer uses a different RTOS, he still can use emNet.

In the world of embedded systems, IP based communication lays the groundwork for any modern device. Internet of Things (IoT) protocols such as MQTT (Message Queue Telemetry Transport) rely on the availability of IP communication. The industry-leading IP stack emNet, is the first choice for the required IP connectivity. This IP stack is straight forward to configure and integrate. emNet can easily be tuned to adapt to the different communication requirements of your embedded system.








  • Professional IP stack for embedded systems
  • ANSI C socket.h-like API for user applications. An application using the standard C socket library can easily be ported to use emNet.
  • High performance IP stack
  • Small memory footprint
  • Runs "out-of-the-box"
  • No configuration required
  • Works with any RTOS in a multitasking environment (embOS recommended)
  • Easy to use on embedded devices

The IP stack for embedded devices emNet, is offered in two different editions, a BASE package which includes the most important protocols related to Ethernet communication, the stack itself, and a PRO package. Depending on the engineer's needs, there are several protocols available as an add-on, as well as the emNet PRO software which adds a device driver, web server functionality, and email client for extended communication via Internet.

Additional modules

 Wifi driver require

The IP stack emNet does not contain any hardware dependencies. These are encapsulated through a hardware abstraction layer, which consists of interface functions. All of these functions for a particular Ethernet controller are typically located in a single file, the emNet driver. More information about these functions can be found in the emNet manual.

Range of Supported Ethernet Hardware

The interface has been designed in such a way that it should be possible to use the most common Ethernet controllers as external chips and part of microcontrollers.
