7.4 TARGET INTERFACE SPECIFICATIONS
The target interface has signals such as GND, SI, SO, SCK, CLK, _RESET, V
DD
, V
PP
, and HS. These signals are
used to connect the target. For the information on the required signal lines, refer to the user's manual for each device.
The PG-FP3 comes with two types of cables that can be used to connect the target. Use of these cables is
recommended.
The target interface is provided with a protection circuit that protects the PG-FP3 from damage due to input of an
overvoltage from an external source. This protection circuit disconnects from the target a signal line that may cause
damage if a signal line with a voltage higher than the rated voltage is connected to the interface by mistake. The
circuit also informs the user of the abnormal condition. If an abnormal condition is detected, check whether the
interface is correctly connected and whether the target is normal. The overvoltage level each signal line of the
interface can withstand is shown below. If a voltage exceeding this level is applied to a signal line, the PG-FP3 may be
damaged.
