Tyco Electronics Amp and is a 38-way receptacle Mictor connector, 0.025” pitch, part number:

767054-1 or 2-5767004-2 (RoHS compliant).

 J10 – this is the new and smaller footprint standard ARM Cortex-M3/M4 connector for trace. It

carries the trace signals as well as the debug signals found on J7. Note that this connector

is not used when working with the LPC4357. Instead a 20 pos trace connector, J1,

exists on the LPC4357 OEM board itself.

When working with the LPC4357 OEM Board, J7 is typically used. If an older and big footprint JTAG

debug pod is used, J8 can alternatively be used.

If trace is also used, use the connector J1 on the LPC4357 OEM board. Note that this requires an

advanced JTAG probe that supports trace.

Note that JP4 shall be shorted in order to enable the JTAG/SWD interface on the LPC4357. JP4

might not be inserted by default on the OEM Base Board.

JP3 is not used for debug purposes when working with the LPC4357 OEM Board.
