Customers must check the quality grade of each semiconductor product before using it in a particular
application.
"Standard": Computers, office equipment, communications equipment, test and measurement equipment, audio
and visual equipment, home electronic appliances, machine tools, personal electronic equipment
and industrial robots
"Special": Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)
"Specific": Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems and medical equipment for life support, etc.
The quality grade of NEC semiconductor products is "Standard" unless otherwise expressly specified in NEC's
data sheets or data books, etc. If customers wish to use NEC semiconductor products in applications not
intended by NEC, they must contact an NEC sales representative in advance to determine NEC's willingness
to support a given application.
(Note)
(1) "NEC" as used in this statement means NEC Corporation and also includes its majority-owned subsidiaries.
(2) "NEC semiconductor products" means any semiconductor product developed or manufactured by or for

Connection Between IE-703002-MC and IE-703079-MC-EM1
The procedure for connecting the IE-703002-MC and IE-703079-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> Set the PGA socket lever of the IE-703079-MC-EM1 to the OPEN position as shown in Figure 1-4 (b).
<3> Connect the IE-703079-MC-EM1 to the PGA socket at the back of the IE-703002-MC pod (refer to Figure 1-4
(c)). When connecting, position the IE-703002-MC and IE-703079-MC-EM1 so that they are horizontal.
<4> Set the PGA socket lever of the IE-703079-MC-EM1 to the CLOSE position as shown in Figure 1-4 (b).
<5> Set the IE-703002-MC pod jumpers (JP1 to JP3).
The factory settings of JP2 are pins 1 and 2 shorted.
<6> Place the supplied spacers in the four corner holes of the IE-703079-MC-EM1. Fix the spacers with the
supplied screws.
<7> Fix the IE-703002-MC pod cover (upper) end with nylon rivets.

CAUTIONS
VDD0 and PORTVDD of Target System
(1) VDD0 in the target system is used to sense the level for target system power supply ON/OFF.
• When VDD0 is lower than 1 V, it is judged that the target system is not connected, and mapping of the target
memory cannot be performed with a debugger (FCAN cannot be used).
• When VDD0 is 1 V or higher, it is judged that the target system is connected, and mapping of the target
memory can be performed with a debugger (FCAN can be used).
(2) PORTVDD in the target system is not supplied directly to the emulator chip; it is connected to the target voltage
emulation circuit.
• When PORTVDD is lower than 3 V, VCC (5 V) in the internal emulator is supplied to the emulator chip.
• When PORTVDD is 3 V or higher, a voltage of the same potential as PORTVDD in the target system is
generated and supplied to the emulator chip.

NMI Signal
The input signal (NMI signal) from the target system is delayed (tpD = 0.25 ns (TYP.)) because it passes through
QS3125 (Q switch), and I/O signals (ports 4, 5, 6, 9, 11) pass through QS3384 (Q switch) before it is input to the
emulator chip.
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 µA (MAX.).

CHAPTER 5
DIFFERENCES BETWEEN TARGET DEVICE AND TARGET INTERFACE CIRCUIT
Differences between the signal lines of the target device and the signal lines of the IE-703079-MC-EM1 target
interface circuit are described in this chapter.
The target device is a CMOS circuit, whereas the target interface circuit of the IE-703079-MC-EM1 is configured
with an emulation circuit such as a gate array TTL or CMOS-IC.
When debugging the IE system connected to the target system, the IE system emulates as if the real target device
is operating on the target system.
Small differences occur however, because the IE system is emulating actual operation.
(1) Signals input/output to/from the emulation CPU µPD70F3079Y
(2) Other signals
The IE-703079-MC-EM1 circuit regarding the (1) and (2) signals described above is as follows.
