6.000 MHz (n = 8)
5.333 MHz (n = 9)
4.800 MHz (n = 10)
Adaptive clocking is supported.
Target Interface
nTRST is push-pull type
RESET is push-pull type
Version 5.2
Identical to version 5.0 with the following exception:
Target Interface
nTRST is push-pull type
RESET is open drain
Version 5.3
Identical to version 5.2 with the following exception:
• 5V target supply current limited
5V target supply (pin 19) of Kick-Start versions of J-Link is current monitored
and limited. J-Link automatically switches off 5V supply in case of over-current to
protect both J-Link and host computer. Peak current (<= 10 ms) limit is 1A,
operating current limit is 300mA.
Version 5.4
Identical to version 5.3 with the following exception:
• JTAG interface is 5V tolerant.
Version 6.0
Identical to version 5.4 with the following exception:
• Outputs can be tristated (Effectively disabling the JTAG interface)
• J-Link supports SWV (Speed limited to 500 kHz)
Version 7.0
• Uses an additional pin to the UART unit of the target hardware for SWV support
(Speed limited to 6 MHz).
Version 8.0
• SWD support for non-3.3V targets.
