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.

CHAPTER 1 GENERAL
The IE-77016-CM-LC is a JTAG signal level converter that converts +5 V JTAG interface signals input/output from
an IE-77016-98/PC, which is an in-circuit emulator for the
µ
PD77016 FamilyNote and the
µ
PD77111 Family, to +3 V or
+2.5 V JTAG interface signals.
By combining the IE-77016-CM-LC with the IE-77016-98/PC and ID77016 (debugger control software), it is
possible to use the in-circuit emulation function built in the
µ
PD77016 Family and the
µ
PD77111 Family.
Figure 1-1 shows the system configuration.
Note The
µ
PD77016 is excluded. In the case of the
µ
PD77016, the +5 V JTAG interface signals input/output
from the IE-77016-98/PC can be input/output as is to the device debug pin. At this time, use the cable
provided with the IE-77016-98/PC.

CHAPTER 3 INSTALLATION
3.1 IE-77016-CM-LC Settings
3.1.1 DIPSW1: Selecting the JTAG interface signal level
This DIP switch is used to select whether to convert the +5 V signal output from the IE-77016-98/PC to +2.5 V or
+3.3 V.
If a device of the
µ
PD77016 Family or
µ
PD77111 Family is used, set this DIP switch to OFF.
To select the +2.5 V input/output voltage for the JTAG interface, for example in order to support ASIC products,
set this DIP switch to ON.
Setting value Function
ON Signal is converted to +2.5 V and output from the TARGET (J1) connector.
OFF Signal is converted to +3.3 V and output from the TARGET (J1) connector (factory setting).
3.1.2 DIPSW2: Forced TRST signal output enable/disable selection
The TRSTB (SW2) switch is used to enable/disable forced TRST signal output.
Normally, set this switch to OFF.
Also, if the target device that is used belongs to the
µ
PD77016 Family, the TRSTB (SW2) switch is disabled
regardless of the setting of this switch.
Setting value Function
ON Enables TRSTB (SW2) switch.
OFF Disables TRSTB (SW2) switch (factory setting).
3.2ýIE-77016-98/PC Settings
Following the instructions given in the IE-77016-98/PC User’s Manual, set up the IE-77016-98/PC to the host
machine.
3.2.1 Connecting the IE-77016-CM-LC and IE-77016-98/PC
Connect the J2 connector of the IE-77016-CM-LC and the CN3 connector of the IE-77016-98/PC to the IE
connection cable supplied with the IE-77016-CM-LC. Do not use the JTAG cable supplied with the IE-77016-98/PC.

µ
PD77016)
Connect the IE-77016-CM-LC to the target system using the 10-pin flat cable supplied with the IE-77016-CM-LC.
First connect the 14-pin connector of the flat cable to the J1 connector of the IE-77016-CM-LC. Then connect the
10-pin connector to the pin provided on the target system side (Refer to APPENDIX TARGET SYSTEM PINS).
3.3.2 In the case of the
µ
µµ
µ
PD77111 Family
Connect the IE-77016-CM-LC to the target system using the 12-pin (or 14-pin) flat cable supplied with the IE-
77016-CM-LC.
First connect the 14-pin connector of the flat cable to the J1 connector of the IE-77016-CM-LC. Then connect the
12-pin (or 14-pin) connector to the pin provided on the target system side (Refer to APPENDIX TARGET SYSTEM
PINS).
Remark Connector pins with 14-pin specifications are recommended for the target system side. In the case of
the supplied flat cables, the 14-pin flat cable is recommended over the 12-pin flat cable due to its higher
strength.
If connecting a connector pin with 12-pin specifications to the target system, the 14-pin flat cable can be
used, if enough space is left when positioning components around the connector pin so that the flat
cable connector does not interfere with the components on the target device. In this case, since there
are no signals for the 2 extra pins of the 14-pin flat cable, no special handling is required for these 2
pins.

Next, switch the power ON following the sequence described below. Follow the reverse sequence when switching
the power OFF.
(1) Switch ON the host machine.
(2) Switch ON the target system.
(3) Set the SW1 of the IE-77016-CM-LC to ONNote (JTAG signal is output).
Note This switch does not control the power of the IE-77016-CM-LC.
Caution If removing or replacing devices on the target system, be sure to set SW1 of the IE-77016-CM-LC
to OFF when you switch OFF the power of the target system.
