Notes:
•
The signals connected to the S5U1C33001H are very high-speed signals, so the target connector must be mounted
within 5 cm from the S1C33xxx. If there is more distance between the connector and the S1C33xxx chip, the
S5U1C33001H may not work properly.
•
A 33 Ω resistor must be connected in series to the DSIO signal line between the connector and the S1C33xxx chip.
The resistor should be placed as close to the S1C33xxx as possible.
•
Be sure to use the supplied 10-pin or 4-pin, or 30-pin cable for Connecting the target system to the S5U1C33001H.
Using another cable may cause a malfunction. Furthermore, do not use the 30-pin cable and 10-pin or 4-pin cable
simultaneously.
•
Disable the trace function of the S5U1C33001H using DIP switch 4 in the following cases:
- when using the 4-pin cable and connector.
- when the signals (DST0, DST1, DPCO) necessary for tracing are not connected even if the 30-pin or 10-pin cable
and connector is used.
- when the trace function is not used due to some reason even if the 30-pin or 10-pin cable and connector is used
and all the signals are connected.
•
The 4-pin connector does not have a projection for preventing reverse insertion. Check the cable marker of pin 1 to be
sure the insertion of connector is proper when connecting it to the target system.
•
The product package does not include a 30-pin cable or the corresponding connector. Please contact us if you need
this cable or the corresponding connector.
