Table 2-4. JP3 and JP4 Setting in IE-703002-MC JP3, JP4 Description JP3 The operation voltage range of the IE-703002-MC is to 2 to 3.6 V 1 2 (Open) JP4 1 The operation voltage range of the target system is 2 to 4.5 V. (Use this setting since the operation voltage range of the V850/SV1 is 2 to 3.6 V.) 2 3 Caution By settings of JP3, JP4 above, when the power supply of the target system is on, the IE-703002MC operates at the same voltage as the target system. The IE-703002-MC always operates at 3.3 V when the power supply of the target system is off and using emulator as standalone unit.

The IE-703002-MC uses BVDD of the target system for the following purposes: * Power ON/OFF detection of target system * BVDD emulation of target system (2) When the voltage of the target system is 1 V or higher, the evaluation chip in the emulator operates using the supply of VDD from the target system. The power consumption is equivalent to that of the V850/SV1. (3) When the voltage of the target system is lower than 1 V, the emulator recognizes the target system power is off and operates at 3.3 V.

In addition, the DC characteristics change. The input voltage becomes VIH = 2.0 V (MIN.), VIL = 0.8 V (MAX.), and the input current becomes IIN = 0.5 A (MAX.). Figure 4-2.
