Next generation of J-Link debugger boosts power resolution

November 19, 2012 // By Nick Flaherty
SEGGER is shipping the 2013 models of the J Link family of debuggers to provide higher performance and greater power consumption resolution.

At 3MB/s the high-end models J-Link PRO, J Link ULTRA+ and J-Link ULTRA support target processor interfaces running up to 60MHz, while the standard J-Link and the J-Link PLUS also benefit from a new platform and raise their download speed to 1MB/s. Power debugging with the J-Link PRO, J-Link ULTRA and J-Link ULTRA+ has been improved to achieve a resolution of 50 uA at sampling frequencies of up to 200 KHz.
The new 2013 models are available at no additional cost and are fully compatible to each other as well as to older models. Owners of previous models may benefit from the new hardware design by making use of SEGGER’s trade-in-program.
“It is easy for a developer to make a choice on his JTAG/SWD emulator. With the new hardware platform, we now offer the fastest, the most robust and the most versatile option in the market”, said Alexander Gruener, J-Link Product Manager of SEGGER. "At 3MB/sec with a maximum Target interface speed of 60MHz, the J-Link ULTRA, ULTRA+ and PRO models are the fastest emulators on the market. As with all J-Links, download into flash memory is supported. Not only the download speed, but all other values such as single step performance is second to none", says Dirk Akemann, Marketing Manager of SEGGER.
The SEGGER J Link supports all major tool chains for ARM cores and works with IDEs from Atmel, Atollic, Freescale, IAR, KEIL, Mentor Graphics, Rowley, Renesas, Tasking, Phyton and others. Any RDI compliant debugger can be used with the optional RDI module, and any GDB compliant debugger with the free GDB-Server.
J-Link supports multiple CPU families, such as ARM 7, 9, 11, Cortex-M0, M1, M3, M4, R4, A5, A8, A9 and Renesas RX in a single model; there is typically no need to buy a new J-Link or new license when switching to a different CPU family or tool-chain.
