'''Segger Microcontroller''' is a private company involved in the embedded systems industry.<ref name="Segger-Home">{{cite web |title=Home Page |url=https://www.segger.com/ |website=Segger |archive-url=https://web.archive.org/web/20241206190353/https://www.segger.com/ |archive-date=December 6, 2024 |url-status=live}}</ref> It provides products used to develop and manufacture four categories of embedded systems: real-time operating systems (RTOS) and software libraries (middleware), debugging and trace probes, programming tools (integrated development environment (IDE), compiler, linker), and in-system programmers (Flasher line of products). The company is headquartered in Monheim am Rhein, Germany, with remote offices in Gardner, Massachusetts; Milpitas, California; and Shanghai, China.
==History== Segger Microcontroller was founded in 1992 by Rolf Segger in Hilden, Germany.<ref name="Segger-About-Company">{{cite web |title=About Us - The Company |url=https://www.segger.com/about-us/the-company/ |website=Segger |archive-url=https://web.archive.org/web/20241206190958/https://www.segger.com/about-us/the-company/ |archive-date=December 6, 2024 |url-status=live}}</ref> The first product was the real-time operating system (RTOS), now named embOS. It was followed by emWin two years later. Initial products focused on RTOS and middleware products. However, the company later produced ISP-programming tools (Flasher) and debug probes (J-Link). In 2015, Segger introduced Embedded Studio, their cross-platform IDE for central processing units conforming to the ARM architecture, though recent versions are also used by RISC-V. All products are developed, maintained and updated in Germany except for Embedded Studio, which is primarily developed by a team of developers in the United Kingdom.
==Product categories== ===Debug and trace probes=== Segger is most noted for its J-Link family, which supports JTAG (Joint Test Action Group) and SWD (Serial Wire Debug) debug probes for microcontrollers that have older ARM cores (ARM7, ARM9, ARM11), ARM Cortex-M cores (M0, M0+, M1, M3, M4, M7, M23, M33, M85), ARM Cortex-R cores (R4, R5, R8), ARM Cortex-A cores (A5, A7, A8, A9, A12, A15, A17, A53, A72), Renesas RX, Microchip PIC32, SiLab EFM8, RISC-V.<ref>[http://www.segger.com/cms/development-tools.html Segger J-Link Product Line]</ref> It is also repackaged and sold as an OEM item<ref>[http://www.edn.com/article/CA6301710.html Advertisement<!-- Bot generated title -->]</ref> by Analog Devices as the mIDASLink, Atmel as the SAM-ICE, Digi International as the Digi JTAG Link, and IAR Systems as the J-Link and the J-Link KS. This is the only JTAG emulator that can add Segger's patented flash breakpoint software to a debugger to enable the setting of multiple breakpoints in flash while running on an ARM device which is typically hindered by the limited availability of hardware breakpoints.<ref>[http://www.circuitcellar.com/library/newproducts/180/segger.htm Circuit Cellar - Digital Library - New Product News<!-- Bot generated title -->] {{webarchive|url=https://web.archive.org/web/20070311133130/http://www.circuitcellar.com/library/newproducts/180/segger.htm |date=2007-03-11 }}</ref>
In the following table, the top group are trace devices, the bottom group are educational / hobbyist devices.
