Customer Questions & Answers
What functional advantages does the J-Link V9 offer over earlier versions such as V7?
The J-Link V9 includes important improvements over the V7 version: it uses an AT91SAM7S64 chip with greater Flash and SRAM capacity, which makes future firmware updates easier. It improves the SWD interface by using a two-level converter that protects the chip against configuration errors, and adds separate status LEDs (USB, target CPU, 5V output). ARM11 support is better and faster, despite SWD speed being slightly lower than on the V7. These changes improve compatibility and safety during debugging.
What are the dimensions, weight and main materials of the J-Link V9 emulator, and what is included in the box when you buy it?
The J-Link V9 emulator typically measures around 90 mm x 45 mm x 20 mm and weighs about 65 g, although these values may vary slightly depending on the manufacturer. It is mainly built from high-strength ABS plastic and internal electronic components. The box usually contains the emulator, a USB Type-A to mini-B (or micro-B) cable, and one or two JTAG/SWD connection cables. It is advisable to check the exact contents with the seller.
What compatibility and connection requirements does the J-Link V9 have with microcontrollers and operating systems?
The J-Link V9 is compatible with ARM7, ARM9, ARM11 and Cortex-M3 architectures, as well as STM32 microcontrollers and similar devices that support JTAG and SWD interfaces. It operates via USB 2.0 and requires a free USB port. It is compatible with development environments such as Keil MDK, IAR EWARM and ADS, and works on Windows and, with the appropriate drivers, on Linux and macOS. The typical target interface operating voltage ranges from 1.2 V to 3.3 V.
What should be considered when installing and setting up the J-Link V9 for the first time?
It is essential to install the latest drivers from SEGGER on your operating system before connecting the device. For the first connection, plug the J-Link V9 into the USB port and then carefully connect it to the target microcontroller’s JTAG/SWD header, respecting the orientation and pinout. Avoid changing the SWD mode if you are unsure about compatibility, to prevent damage to the device.
What are the speed or debugging performance limitations compared with alternatives such as ST-Link or CMSIS-DAP?
The J-Link V9 offers competitive transfer and debugging speeds compared with alternatives such as ST-Link or CMSIS-DAP, although SWD speed is marginally lower than on the V7 (around 1–3 MHz depending on configuration). Its main advantage lies in stability, broad ARM core support and compatibility with multiple IDEs. ST-Link is usually faster on STM32 but only supports STM chips, whereas J-Link has more universal ARM support and better state handling.
Which ARM cores is the J-Link V9 compatible with?
The J-Link V9 is compatible with ARM7TDMI cores (Rev. 1, 3 and 4), ARM720T, ARM920T, ARM926EJ-S, ARM946E-S, ARM966E-S, ARM11 and Cortex-M3.
Which development environments does the J-Link V9 support?
It supports environments such as IAR EWARM, ADS, KEIL, WINARM and Real View, making integration and debugging easier in these systems.
What is the maximum JTAG transfer speed?
The maximum JTAG transfer speed is 12 MHz, with download speeds of up to 600 kB/s for ARM7 and 550 kB/s for ARM9.
Which operating systems are compatible with this emulator?
It is compatible with Microsoft Windows 2000, XP, 2003 and Vista, including 64-bit versions.
Is the J-Link V9 currently available to buy?
The product is currently out of stock. We recommend checking availability on the website or looking for similar alternatives.
