ECU14 JTAG 10-pin 1.27mm Converter
|
The ECU14 connector and the pinout has been defined by Bosch. A converter connecting at the end of the 14-pin 2.54mm MPC5xxx Debug Adapter (Ordering code IC50150) is available for the MPC5xxx/SPC5 target featuring the ECU14 10-pin 1.27mm connector and must be ordered separately.
|
This converter supports only the JTAG debug interface. |
Converter can be used for MPC5xxx/SPC5 architecture or Infineon TriCore since both can feature ECU14 target connection connector. For this reason the converter provides two “input” connectors. Use 14-pin 2.54 mm connector when used for the MPC5xxx/SPC5 architecture. If the converter would be used for Infineon TriCore architecture, 16-pin 2.54 mm connector would be used. Don’t use this “input” in conjunction with the MPC5xxx/SPC5 architecture.
The following pinout is valid on the target side:

10-pin Bosch ECU14 target pinout
Signal Direction is described from the BlueBox perspective.
|
When initially connecting the BlueBox to a target, ensure the debug adapter pinout matches the Target connector to avoid potential hardware failure. |
Jumper J2
The jumper J2 is optional and by default not bridged. 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 (pin 7) is detected.
The converter connects to the target via a 10-pin 1.27mm connector, Samtec SFM-105-01-S-D). A target should feature a matching part, for example Samtec TFM-105-01-L-D.
|
This converter is used only in conjunction with the 14-pin 2.54mm MPC5xxx Debug Adapter (Ordering code IC50150) or alternatively with the 16-pin 2.54mm Infineon JTAG Debug Adapter (Ordering code IC50160) when used for TriCore architecture. |
|
Make sure this adapter fits on your target connector - check Cross Table. |
