6.1 Notes on Use of ICDmini Ver. 3.0
• Turning power on/off
The ICDmini Ver. 3.0 requires at least a 10-second interval between turning power off once and turning power
on again by unplugging and plugging the USB cable. If not enough interval is taken between power off and on,
the power-on reset may not be performed normally and the ICDmini Ver. 3.0 may not operate normally or it
may cause a malfunction.
• Connecting with the target system
Since very high-speed signals are connected to the ICDmini Ver. 3.0, the connector on the target system must be
placed within 5 cm from the target S1C17 MCU. Otherwise, the ICDmini Ver. 3.0 may not operate normally.
Furthermore, the supplied 10-pin cable or an optional 10-pin cable compatible with the the ICDmini Ver. 1.0,
1.1, and 2.0 (refer to Appendix B) should be used for connecting the ICDmini Ver. 3.0 with the target system.
• Operating the ICDmini Ver. 3.0 system
To operate the ICDmini Ver. 3.0 system, a target system that includes an actual S1C17 MCU should be prepared
by the user, as no target system board is included in the ICDmini Ver. 3.0 package.
• Wiring between the S1C17 MCU to the connector on the target system
For the signals and elements to be connected, refer to the Technical Manual for the target S1C17 MCU.
• Target system interface voltage
The allowable voltage range of the signals input to the ICDmini Ver. 3.0 through the target system connection
cable is 1.2 to 5.5 V. If a voltage that exceeds the range is applied, the ICDmini Ver. 3.0 may become damaged.
The target system to be connected should be designed so that voltage out of the range, especially overvoltage
that may occur when the target system is turned on and off, will not be applied to the ICDmini Ver. 3.0.
• Execution counter
The execution counter included in the ICDmini Ver. 3.0 can measure execution time up to 4,294.967295
seconds. The minimum resolution is 1 µs, so a time shorter than 1 µs cannot be measured. A measurement error
within ±30 ppm may occur due to the accuracy of the resonator included in the ICDmini Ver. 3.0.
6.2 Other
• The ICDmini Ver. 3.0 should be used so that the surface with screw holes is facing down.
• Use the USB cable and target system connection cable included in the ICDmini Ver. 3.0 package.
• The ICDmini Ver. 3.0 should be used indoors.
• Do not use the ICDmini Ver. 3.0 with the bottom cover left open except when the firmware is updated, as it may
cause a malfunction.
