Descriptions of circuits, software and other related information in this document are provided for illustrative  
purposes in semiconductor product operation and application examples. The incorporation of these  
circuits, software and information in the design of customer's equipment shall be done under the full  
responsibility of customer. NEC assumes no responsibility for any losses incurred by customers or third

While NEC endeavours to enhance the quality, reliability and safety of NEC semiconductor products, customers  
agree and acknowledge that the possibility of defects thereof cannot be eliminated entirely. To minimize  
risks of damage to property or injury (including death) to persons arising from defects in NEC  
semiconductor products, customers must incorporate sufficient safety measures in their design, such as  
redundancy, fire-containment, and anti-failure features.  
NEC semiconductor products are classified into the following three quality grades:  
"Standard", "Special" and "Specific". The "Specific" quality grade applies only to semiconductor products  
developed based on a customer-designated "quality assurance program" for a specific application. The  
recommended applications of a semiconductor product depend on its quality grade, as indicated below.  
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  
NEC (as defined above).

The procedure for connecting the IE-703002-MC and IE-703089-MC-EM1 is described below.  
Caution  
Connect carefully so as not to break or bend connector pins.  
<1> Remove the pod cover (lower) of the IE-703002-MC.  
<2> Set the PGA socket lever of the IE-703089-MC-EM1 to the OPEN position as shown in Figure 1-4 (b).  
<3> Connect the IE-703089-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-703089-MC-EM1 so that they are horizontal.  
<4> Set the PGA socket lever of the IE-703089-MC-EM1 to the CLOSE position as shown in Figure 1-4 (b).  
<5> When connecting the probe (SWEX-144SD-1) to the IE-703089-MC-EM1, attach it to CN1 on the rear of the  
IE-703089-MC-EM1, aligning each pin 1 (refer to Figure 1-5).  
<6> Place the supplied spacers in the four corner holes of the IE-703089-MC-EM1. Fix the spacers with the  
supplied SEMS screws.  
<7> Fix the IE-703002-MC pod cover (upper) with nylon rivets.

CHAPTER 4 CAUTIONS  
4.1 VDD and PORTVDD of Target System  
(1) VDD in the target system is used to sense the level for target system power supply ON/OFF.  
When VDD is lower than 3.5 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 VDD is 3.5 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) PORTVDDn (n = 0 to 2) in the target system is not supplied directly to the emulator chip; it is connected to the  
target voltage emulation circuit.  
When PORTVDDn is lower than 3.3 V, VCC (5 V) in the internal emulator is supplied to the emulator chip.  
When PORTVDDn is 3.3 V or higher, a voltage of the same potential as PORTVDDn in the target system is  
generated and supplied to the emulator chip.

CHAPTER 4 CAUTIONS  
(3) The VDD1 signal from the target system is left open in the IE-703089-MC-EM1.  
(4) The following conditions must be satisfied when other than VDD0 = VDD1 = ADCVDD = PORTVDD1 = PORTVDD2.  
1. When FCAN is used, PORTVDD1 PORTVDD2 (restricted by the power supply voltage conditions of the in-  
circuit emulator)  
2. When ADC is used, VDD0 = ADCVDD = 4.5 to 5.5 V  
4.2 I/O Signal  
The input signal (NMI signal) from the target system, the I/O signals for ports 4, 5, 6, and 11, and the I/O signal for  
port 9 are all delayed (tPD = 0.25 ns (typ.)) because they pass through Q switches QS3125, QS3384, and QS3244,  
respectively, before being input to the emulator chip.  
The DC characteristics also 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-703089-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-703089-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.
