Dimension

Connector Type

  • This is a standard 14 pin double row (two rows of seven pins) connector (pin to pin spacing: 2.54mm/0.100").

  • If terminal strip without shroud is used, the spacing marked with "A" must be a minimum of 23mm/0.9".

JTAG connector recommendations

  • TDI, TDO, TCK, TMS and JCOMP- should be connected directly to the CPU. Don't connect serial resistors or RC terminations to those signals.

  • Avoid routing the JTAG signals close to the NEXUS signals.

  • Connect VDD to the voltage which also supplies the processor's JTAG signals (esp. TDO). VDD can be connected directly to the target's power supply, or optional with a resistor < 5kOhm

  • The RDY- signal (pin 13) is optional.
    If the signal is not available, or can not be connected because of other reasons, the RDY- pin on the debug connector should be connected to GND.
    If the RDY- signal on the debug connector is not connected, set SYStem.Option.NOJTAGRDY ON.

  • If the signal JCOMP (pin 14) is not available on the used processor/package type, leave the JCOMP pin on the debug connector unconnected.

  • We recommend to follow Freescale's Application Note AN2614.

Debug Cable Information

  • When the debugger is inactive (SYStem.Mode.DOWN and NoDebug), all output pins of the debug cable are tri-stated (hot-plug capability)

  • During the debug session: TDI, TCK, TMS and JCOMP- are driven to both low and high levels. Only RESET is an open-drain output. The voltage level of a pin driven to high is the same soltage level as connected to VDD target (pin 11).

  • All output signals of the debug cable have a 47 Ohm serial termination. Usually no further termination is needed on the target hardware.

  • Maximum supported voltage range (check debug cable's serial number CYYMMxxxxxx):
    • Debug cable produced before 09/2009: 1.8-5.5V
    • Debug cable produced 09/2009 or later: 0.9-5.5V

  • Input impedance on VDD target (pin 11):
    • Debug cable produced before 09/2009: >45 kOhm
    • Debug cable produced 09/2009 or later: >90 kOhm

  • IEEE 1149.7 (aka cJTAG) supported by debug cables produced 09/2009 or later.
