Segger Microcontroller, founded in 1992, is a private company involved in the embedded systems industry. 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. 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. [1] It is also repackaged and sold as an OEM item [2] 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.

AVR is a family of microcontrollers developed since 1996 by Atmel, acquired by Microchip Technology in 2016. These are modified Harvard architecture 8-bit RISC single-chip microcontrollers. AVR was one of the first microcontroller families to use on-chip flash memory for program storage, as opposed to one-time programmable ROM, EPROM, or EEPROM used by other microcontrollers at the time.

In-circuit emulation (ICE) is the use of a hardware device or in-circuit emulator used to debug the software of an embedded system. It operates by using a processor with the additional ability to support debugging operations, as well as to carry out the main function of the system. Particularly for older systems, with limited processors, this usually involved replacing the processor temporarily with a hardware emulator: a more powerful although more expensive version. It was historically in the form of bond-out processor which has many internal signals brought out for the purpose of debugging. These signals provide information about the state of the processor.
