Segger Microcontroller Type GmbH Industry Embedded software Products Middleware components, JTAG development tools Website www.segger.com

**Segger Microcontroller** is a private company involved in the [embedded systems](/source/Embedded_system) industry.[1] It provides products used to develop and manufacture four categories of embedded systems: [real-time operating systems](/source/Real-time_operating_system) (RTOS) and software [libraries](/source/Library_(computing)) ([middleware](/source/Middleware)), [debugging](/source/Debugging) and [trace](/source/Stack_trace) probes, [programming tools](/source/Programming_tool) ([integrated development environment](/source/Integrated_development_environment) (IDE), [compiler](/source/Compiler), [linker](/source/Linker_(computing))), and [in-system programmers](/source/In-system_programming) (Flasher line of products). The company is headquartered in [Monheim am Rhein](/source/Monheim_am_Rhein), Germany, with remote offices in [Gardner, Massachusetts](/source/Gardner%2C_Massachusetts); [Milpitas, California](/source/Milpitas%2C_California); and [Shanghai](/source/Shanghai), China.

## History

Segger Microcontroller was founded in 1992 by Rolf Segger in [Hilden](/source/Hilden), Germany.[2] The first product was the [real-time operating system](/source/Real-time_operating_system) (RTOS), now named embOS. It was followed by emWin two years later. Initial products focused on RTOS and [middleware](/source/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](/source/Cross-platform_software) IDE for [central processing units](/source/Central_processing_unit) conforming to the [ARM architecture](/source/ARM_architecture), though recent versions are also used by [RISC-V](/source/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](/source/United_Kingdom).

## Product categories

### Debug and trace probes

Segger is most noted for its J-Link family, which supports [JTAG](/source/JTAG) (Joint Test Action Group) and SWD (Serial Wire Debug) debug probes for microcontrollers that have older ARM cores ([ARM7](/source/ARM7), [ARM9](/source/ARM9), [ARM11](/source/ARM11)), ARM Cortex-M cores ([M0](/source/ARM_Cortex-M0), [M0+](/source/ARM_Cortex-M0%2B), [M1](/source/ARM_Cortex-M1), [M3](/source/ARM_Cortex-M3), [M4](/source/ARM_Cortex-M4), [M7](/source/ARM_Cortex-M7), [M23](/source/ARM_Cortex-M23), [M33](/source/ARM_Cortex-M33), M85), ARM Cortex-R cores ([R4](/source/ARM_Cortex-R4), [R5](/source/ARM_Cortex-R5), [R8](/source/ARM_Cortex-R8)), ARM Cortex-A cores ([A5](/source/ARM_Cortex-A5), [A7](/source/ARM_Cortex-A7), [A8](/source/ARM_Cortex-A8), [A9](/source/ARM_Cortex-A9), [A12](/source/ARM_Cortex-A12), [A15](/source/ARM_Cortex-A15), [A17](/source/ARM_Cortex-A17), A53, A72), [Renesas RX](/source/Renesas_RX), Microchip [PIC32](/source/PIC32), [SiLab](/source/Silicon_Labs) EFM8, [RISC-V](/source/RISC-V).[3] It is also repackaged and sold as an OEM item[4] by [Analog Devices](/source/Analog_Devices) as the mIDASLink, [Atmel](/source/Atmel) as the SAM-ICE, [Digi International](/source/Digi_International) as the Digi JTAG Link, and [IAR Systems](/source/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](/source/Breakpoint) in flash while running on an ARM device which is typically hindered by the limited availability of hardware breakpoints.[5]

In the following table, the top group are trace devices, the bottom group are educational / hobbyist devices.

- Note: Further models are J-Link LITE ARM, J-Link LITE CortexM, J-Link LITE RX, J-Link OEM.[8]

- Note: Software options vary by model: J-Flash, J-Flash-SPI, Ozone, RDDI, RDI, Unlimited Flash Breakponts.

- Note: The EDU & EDU Mini models cannot be used for commercial software development, also doesn't come with J-Flash, J-Flash-SPI, RDDI, RDI options.

- Note: Adapters and isolators are available to convert the 20-pin 0.1"/2.54mm [male shrouded (box) header](/source/Pin_header) to another target board connector.[9]

- Note: The compact variants are functionally identical to their larger variants.
