Mictor 38-pin ARM ETM 8-bit Cable Adapter
Ordering code
IC50114
This adapter is used to connect the iC5000 / iC5500 / iC5700 development system to ARM7/ARM9 based target.
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 Mictor 38-pin target debug connector with ARM7/ARM9 ETM pinout.
Only 4 or 8-bit ETM port width (physical port size) is supported with this adapter. However, it can be also used
for ETM trace on targets where physically more than 8 ETM data lines are connected to the target debug
connector by configuring the on-chip ETM module for operation with 8 or less data lines (‘Hardware/CPU
Setup/ETM tab). Note that ETM port bandwidth proportionally drops off when less ETM data lines are used and
trace overflows are more likely to occur. If maximum bandwidth is needed, use IC50115, ARM ETM 16-bit
cable adapter.
The following pinout is valid on the target side:

8-bit ARM ETM target pinout
Blue colored signals are required for trace.
Note: Mictor 38-pin ARM ETM Cable Adapter features resettable fuses on pins 9, 11, 12, 15, 17, 19 and 21.
These protect debug signals against overcurrent and cycle back to a conductive state after the excessive current
fades away. Signals on pins 6, 16, 18, 20, 22, 24, 26, 26, 28, 30, 32, 34, 36 and 38 are protected via 47 ohm
serial resistors.
The adapter connects to the target via a 38-pin Mictor connector (Tyco Electronics 5767055-1). A target should
feature a matching part (for example Tyco Electronics 5767081-1 in SMT technology).
