Segger J-Link family ARM debug probes and Memory Programmers

Home » Segger J-Link family ARM debug probes and Memory Programmers

The SEGGER J-Link debugger is the most widely used line of debug probes on the embedded development market. For more than a decade, it has provided solid value to embedded engineers worldwide. Furthermore, Sightsys officially distributes the SEGGER J-Link family in Israel, offering local sales, technical support, and fast delivery to Israeli development teams.

Why Choose the SEGGER J-Link Debugger

Unparalleled performance, an extensive feature set, broad CPU support, and compatibility with popular development environments all make J-Link an unbeatable choice. In addition, J-Link debug probes optimize the entire debugging and flash programming experience. For example, you benefit from record-breaking flash loaders, RAM download speeds up to 4 MB/s, and the ability to set an unlimited number of breakpoints in the flash memory of MCUs.

Moreover, J-Link supports a wide range of CPUs and architectures. From single 8051 chips, through mass-market Cortex-M devices, all the way to high-end Cortex-A cores (32-bit and 64-bit), J-Link covers virtually every modern embedded platform. As a result, it has become the standard tool for professional embedded developers worldwide.

Direct SPI Flash Programming

In contrast to traditional debuggers, the SEGGER J-Link debugger directly interfaces with SPI flash devices. Therefore, you don’t need a CPU between J-Link and the SPI flash, because it communicates via the SPI protocol directly. This dramatically simplifies production programming workflows.

Supported IDEs

All major embedded IDEs support the SEGGER J-Link debugger, including:

  • SEGGER Embedded Studio
  • Visual Studio Code
  • IAR Embedded Workbench
  • Keil MDK
  • Eclipse-based environments

Jlink-Base

J-Link BASE is a USB-powered JTAG debug probe supporting a large number of CPU cores. Based on a 32-bit RISC CPU, it can communicate at high speed with the supported target CPUs. J-Link is used around the world in tens of thousand places for development and production (flash programming) purposes.

The J-Link debug probes are supported by all major IDEs including Eclipse, GDB-based IDEs and SEGGER Embedded Studio. For a complete list, please refer to supported IDEs. Including all models, more than 1,000,000 J-Links have been shipped so far, making J-Link probably the most popular debug probe for Arm cores and the de-facto standard.

The J-Link BASE as a member of the SEGGER J-Link debug probes supports a wide range of CPU cores. The list of supported manufacturers, families, and devices and SoCs includes tens of thousands of devices in hundreds of device families.

Jlink-Plus

J-Link PLUS is a USB-powered JTAG debug probe supporting a large number of CPU cores. Based on a 32-bit RISC CPU, it can communicate at high speed with the supported target CPUs. J-Link is used around the world in tens of thousands of places for development and production (flash programming) purposes. with Jlink plus you can use Jflash programing software to program the MCU without the need of using the development IDE.

Jlink Ultra+

Up to 4 MB/s download speed make J-Link ULTRA+ the fastest debug probe on the market.

it also has fast SWO speed for fast output from the target.

Jlink-Pro

J-Link PRO is fully compatible with J-Link and can be used “out-of-the-box”. J-Link PRO uses DHCP per default. The built-in web server makes manual configuration easy. Ethernet allows the use of the debug probe far away from the PC, over a hardwired or wireless network, in a development or production environment. It also makes download and debugging speeds higher and provides electrical isolation from the PC. The product also comes with all features of the regular J-Link.
