1. Product description
The SICA20I2P is designed to save space on the target board when using JTAG
equipment to test, debug or evaluate a system. The target board connector has a 5 x 7mm
footprint, which is 1/6th the size compared with traditional connector with 2.54mm pitch.
This cable adapter converts 2.54mm pitch connector at an emulator side into 0.5mm pitch
at a target board. Therefore, this cable can be placed closed to CPU. The target board
connector surface mounted on PCB without needing any “through holes”. Now, the other
side of PCB is available for mounting more components.

3. How to use it:
1. Turn off the power to emulator and the
target board! Connect the emulator cable,
the emulator and target board as shown in
Fig 3.1.
A polarity key prevents the user to plug the
emulator cable and the SICA together in the
wrong direction as shown in Fig 3.2. Check
the key’s position before assembling the
header and the socket.
2. Again observing the proper key alignment,
plug the socket on SICA cable target end
onto the header on the target board as
shown in Fig3.3.

4. Cable wiring diagram
Cable wiring diagram is shown in
Fig4.1. Triangle mark indicates
pin#1. The pin#1 on the SICA
connected to pin#1 on the other end.
That is, pins are connected to
straight across the cable.
5. Notes for handling SICA -Small Interface Cable Adapter-
1) SICA is developed for tests, evaluations, and / or development of the electronics system
development in laboratory environment; Therefore SICA does not satisfy any EMI
standards or safety rules.
2) SICA should not be used for the electronics or electrical systems where EMI and
reliability against environments can be a safety factor, such as transportation, medical,
navigation, nuclear power control system and etc.
3) While developing a new application using SICA make sure you follow the pin diagram
exactly as shown in this manual.
4) Do NOT bend flex cable too sharply, because it might break the internal conductive
trace. Insert or extract the cable using the stiffener.
Specifications, the mechanical construction, all other information might be changed without notice.
