The information in this document is current as of August, 2002. The information is subject to
change without notice. For actual design-in, refer to the latest publications of NEC's data sheets or
data books, etc., for the most up-to-date specifications of NEC semiconductor products. Not all
products and/or types are available in every country. Please check with an NEC sales representative
for availability and additional information.

written consent of NEC. NEC assumes no responsibility for any errors that may appear in this document.
NEC does not assume any liability for infringement of patents, copyrights or other intellectual property rights of
third parties by or arising from the use of NEC semiconductor products listed in this document or any other
liability arising from the use of such products. No license, express, implied or otherwise, is granted under any
patents, copyrights or other intellectual property rights of NEC or others.
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).

INTRODUCTION
Product Overview The IE-178054-NS-EM1 is designed to be used with the IE-78K0-NS or IE-78K0-NS-A to
debug the following target devices that belong to the 178K Series of 8-bit single-chip
microcontrollers.

Target Readers This manual is intended for engineers who will use the IE-178054-NS-EM1 with the IE-
78K0-NS or IE-78K0-NS-A to perform system debugging.
Engineers who use this manual are expected to be thoroughly familiar with the target
device’s functions and use methods and to be knowledgeable about debugging.
Organization When using the IE-178054-NS-EM1, refer to not only this manual (supplied with the IE-
178054-NS-EM1) but also the manual that is supplied with the IE-78K0-NS or IE-78K0-
NS-A.
The IE-78K0-NS used in combination with the IE-78K0-NS-PA is functionally equivalent
to the IE-78K0-NS-A. As necessary therefore, read IE-78K0-NS + IE-78K0-NS-PA for IE-
78K0-NS-A in this document.

CHAPTER 3 INSTALLATION
This chapter describes methods for connecting the IE-178054-NS-EM1 to the IE-78K0-NS or IE-78K0-NS-A,
emulation probe, etc. Mode setting methods are also described.
Caution Connecting or removing components to or from the target system, or making switch or other
setting changes must be carried out after the power supply to both the IE system and the target
system has been switched OFF.

CHAPTER 3 INSTALLATION
User’s Manual U16043EJ2V0UM 19
3.1 Connection
(1) Connection with IE-78K0-NS or IE-78K0-NS-A main unit
See IE-78K0-NS User’s Manual (U13731E) for a description of how to connect the IE-178054-NS-EM1 to the IE-
78K0-NS. See IE-78K0-NS-A User’s Manual (U14889E) for a description of how to connect the IE-178054-NS-
EM1 to the IE-78K0-NS-A.
(2) Connection with emulation probe
See the manual of the in-circuit emulator to be used (IE-78K0-NS User’s Manual (U13731E) or IE-78K0-NS-A
User’s Manual (U14889E)) for a description of how to connect the emulation probe to the IE-178054-NS-EM1.
Connect the emulation probe to CN2 on the 178054 PROBE board.
(3) Connection with 178054 PROBE board
Connect CN5 of the IE-178054-NS-EM1 and CN1 of the 178054 PROBE board, aligning pin 1 of each.
(4) Connection with BNC PROBE
Connect the supplied BNC PROBE to the J1 to J4 connectors on the IE-178054-NS-EM1.
Signals corresponding to J1 to J4 are as follows. Connect to amplify inputs from the target system.
J1: VCOL
J2: VCOH
J3: FMIFC
J4: AMIFC
Cautions 1. Incorrect connection may damage the IE system.
Be sure to read the emulation probe’s user’s manual for a detailed description of the
correct connection method.
2. Do not use CN6 as this connector is for expansion.
