1.6 Connection between IE-703002-MC and IE-703017-MC-EM1
The procedure for connecting the IE-703002-MC and IE-703017-MC-EM1 is described below.
Caution Connect carefully so as not to break or bend connector pins.
<1> Remove the pod cover (upper and lower) of the IE-703002-MC.
<2> Replace the crystal oscillator mounted in the pod of the IE-703002-MC with the attached crystal oscillator (17
MHz) or user’s oscillator (with user’s frequency).
<3> Set the PGA socket lever of the IE-703017-MC-EM1 to the OPEN position as shown in Figure 1-4 (b).
<4> Connect the IE-703017-MC-EM1 to the PGA socket at the back of the pod (refer to Figure 1-4 (c)). When
connecting, position the IE-703002-MC and IE-703017-MC-EM1 so that they are horizontal.
<5> Set the PGA socket lever of the IE-703017-MC-EM1 to the CLOSE position as shown in Figure 1-4 (b).
<6> Set the jumpers (JP1 to JP4). Open JP1 and JP3 (Remove the jumper contact. Attach the removed jumper
contact to one of the jumper pins to avoid losing them.)
Retain the factory settings of JP2 (first and second pins shorted, and the fifth and sixth pins shorted).
Short the second and third pins of JP4.
<7> Fix the IE-703017-MC-EM1 between the pod covers (upper and lower) with the plastic screws (supplied in
IE-703002-MC).
<8> Secure the pod cover (upper) end with nylon rivets.
Remark For JP1 setting, refer to 2.3 Illegal Access Detection ROM Setting. For JP3 and JP4, refer to
2.4 CPU Operation Voltage Range Switch Setting.

(Open)
Operating voltage range of target system is from 2 to 4.5 V. (Since operating
voltage of V850/SA1 is from 2 to 3.6 V, this setting is effective)

Caution With the setting of JP3 and JP4, the IE-703002-MC operates in the same voltage as the target
system if the target system power is ON. If the target system power is OFF or the emulator is used
as a stand-alone unit, the IE-703002-MC always operates in 3.3 V.

CHAPTER 4 CAUTIONS
4.1 VDD and BVDD of Target System
(1) BVDD in the target system is not connected to BVDD in the evaluation chip in the IE-703002-MC.
The IE-703002-MC uses the 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 is supplied VDD to
operate by the target system. The power consumption is equivalent to that of the µPD70F3017.
(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.

CHAPTER 4 CAUTIONS
4.2 NMI Signal
The input signal (NMI signal) from the target system is delayed (tpD = 10 ns (MAX.)) because it passes through
FPGA before it is input to the I/O chip of the emulator.
In addition, the DC characteristics change. The input voltage becomes VIH = 2.0 V (MIN.) and VIL = 0.8 V (MAX.).
The input current becomes IIN = ±1.0 µA (MAX.).

4.3 VPP Signal
The VPP signal from the target system is connected to LED via a 330-Ω resistor in the emulator. It is not
connected to the evaluation chip in the emulator.

4.4 MAM Register
Debugging of MAM register cannot be performed in the emulator. If debugging MAM register with software,
proceed with care.
In the target device, the port can be used as an address bus by setting a value to the MAM register (address:
FFFFF068H) that is mapped in the internal peripheral I/O area with the software (Separate bus function). In the
emulator, however, switching to the separate bus through MAM register setting by software is impossible.
To use the separate bus function, set the J1 jumper in advance. (refer to 2.5 Separate Bus Function Setting)

CHAPTER 4 CAUTIONS
4.5 NMI Signal Mask Function
When using the P00/NMI pin in the port mode, do not mask the NMI signal.
4.6 Bus Interface Pin
The operation of the pin for the bus interface differs between the emulator and the target device as follows.
