Segger J-Link 5V JTAG Adapter (8.08.15)

J-Link 5V JTAG Adapter, RoHS, Segger

The J-Link 5V JTAG Adapter extends the output voltage range of J-Link to 5V. Most targets have JTAG signals at voltage levels between 1.2V and 3.3V. These targets can be used with J-Link ARM without a 5V adapter. Higher voltages are common primarily in the automotive sector.
Note: Current J-Links are 5V tolerant, but output levels are limited to about 4V (See J-Link specifications for more details).
These output levels are sufficient for most 5V targets, meaning that current J-Links can be used with most 5V targets without adapter. The adapter is only required for 5V targets that require (input) signals above 3.3V.

Technical data

• 20 pin connector, female (plugs into J-Link)
• 20 pin connector male, for target ribbon cable
• LED shows power status
• Adapter is powered by target
• Power consumption < 20 mA
• Target supply voltage: 3.3V - 5V
• Max. JTAG-frequency: 12 MHz

Compatibility noteThe J-Link ARM 5V JTAG adapter is compatible to J-Link ARM revisions 5 or newer.

Usage

The 5V JTAG adapter should be plugged directly into J-Link ARM with the 20 pin female connector. The target ribbon cable is then attached to the 20 pin male connector of the adapter. The picture below shows a J-Link ARM with a connected 5 volt adapter.
