10-pin 1.27mm Tricore ECU14 Cable Adapter
Ordering code
IC50160-ECU14
This connector has been defined by Bosch and supports JTAG debug interface.
This adapter is used to connect the iC5000 / iC5500 / iC5700 development system to Infineon XC166, XC2000
and TriCore based target via JTAG debug interface. It connects to Debug/Trace module on one side and to the
target debug connector on the other side. It can be used for targets featuring 10-pin 1.27 mm pitch target debug
connector with Bosch ECU14 pinout.
The following pinout is valid on the target side:

10-pin Bosch ECU14 target pinout
Mandatory pins on the microcontroller side are TMS, TDO, TDI, ~TRST, TCLK and ~RESET. USERIO signal
can be used optionally.
Note: 10-pin 1.27mm TriCore ECU14 Cable Adapter features resettable fuses on all connected pins. These
protect debug signals against overcurrent and cycle back to a conductive state after the excessive current fades
away.
Jumper J1
Jumper J1 has been put on the adapter only for making provision for future extensions of the “ECU14” target
connection. The USERIO signal (target debug connector pin 7) is connected to the emulator output (J1 position
1-2) or to the emulator input (J1 position 2-3). Currently the signal has no functionality and consequentially J1 is
not populated. Shall the USERIO signal become functional, the jumper position will become relevant and a
support from the emulator will be required.
Jumper J2
Jumper J2 is optional and by default not populated. It connects 10k pull-down resistor to the USERIO pin when
bridged.
The jumper has been introduced for a custom target, where the target watchdog gets disabled during the
debugging, when low level at the USERIO signal (target debug connector pin 7) is detected.
The adapter connects to the target via a 10-pin 1.27mm connector (for example SAMTEC: SFM-105-01-S-D). A
target should feature a matching part (for example SAMTEC: TFM-105-01-L-D).
