About Connection to Target System
Seeing the following pin assignment table, etc., lay out/mount the Communication Connector (FTSH series 20pin connector made by Samtec, Inc.) on to the target system where the On-chip debug emulation system is to be connected.
One Communication Connector comes with an emulator, but those of the identical series (FTSH series) released from Samtec, Inc. are also available.

(Notes) For the MCU pin numbers, signal names and connection method, be sure to see a data sheet for the target MCU.
Note for Layout of Communication Cable Connector
To monitor the waveforms of the EI_TRGIN and EO_TRGOUT signals, prepare external I/O pins on the target system as required. The following figure shows the cable pull-out direction and connector pin position, when the emulator is connected. To design the board, take into account interference with other parts at the time of connecting the communication cable. For a connector size, please visit Samtec, Inc. website.
Points of concern in signal wiring
To monitor the waveforms of the EI_TRGIN and EO_TRGOUT signals, prepare external I/O pins on the target system as required.
Each debug communication signal should be connected by locating the communication cable connecor within 10 cm (4 inches) from the MCU. Especially, the EI_SYNCLK, EO_MCUDATA, EI_PODDATA, EO_MCUREQ and EI_PODREQ signals must be connected with the same length of wire. If the wire length is longer than 10 cm, or it varies greately among these signals, proper operation may not be obtained.
All the DVCC3A and GND lines between the MCU and the communication cable connector should be as short as possible (preferably within 5 cm, within 10 cm at the longest). If the DVCC3A and GND lines are long, proper operation may not be ontained.
The communication connector should be connected directly to the MCU pattern. If a dumping resistor is inserted between the MCU and the communication cable connector, be careful of signal delays.
About Emulation Operating Voltage/Frequency
- Any operating Voltage/Frequency in the device operation assurance range is available.
- Note that the power/clock cannot be supplied from the emulator to the target system.
Limitation of the On-Chip Debug Emulation
- When connecting an on-chip debug emulator to a debug target system, communication pins and monitor pins are not available as a combined feature because they are occupied by the emulator.
- For the operation assurance range and characteristics of the supplied power/clock, see the microcomputer's datasheet.
Precautions for USB Connection
- The emulator is connected to the host system via the USB. (USB2.0 High-speed)
- To newly connect the emulator to the host system, it is necessary to install a USB driver.
