S5U1C62N51E1 MANUAL (Rev.1.0)
5.1.1 Creation of target system
Mount the LCD panel, keys, and switches on the board to build a target system. Use the I/O connector and LCD
connector supplied with the S5U1C62N51E1 to connect the S5U1C62N51E1 to the target system. (For the pin
layout of each connector, refer to Section 3.3, "S5U1C62N51E1 I/O and LCD Connectors".)
Note: There is some difference in specifications between the S5U1C62N51E1 and the actual CPU. Refer to Section
6.2, "Differences from Actual IC" when building a target system.
5.1.2 Creation and installation of ROMs
Create the program ROMs, function option ROM and segment option ROM, and insert them into the sockets of the
S5U1C62N51E1.
• Program ROMs (two)
The program ROMs contain the application program machine code. Write the HEX files output by the
ASM62N51, 6S3N7, 60N01, 60N02, 60N05 cross-assembler for S5U1C62N51E1 into EPROMs to create
program ROMs. Since two HEX files containing the high-order section (C251XXXH.HEX*) and the low-order
section (C251XXXL.HEX*) of the machine code are output, two ROMs are created. Insert them into the socket
H.HEX and L.HEX under the top cover, respectively.
These ROMs are not necessary when connecting the
S5U1C62N51E1 to the ICE. In addition, it is necessary to
write the object data into the EPROM attaching the offset
address as Table 5.1.2.1 according to the type of EPROM that
is used.
EPROM type
Offset value
27C64
0000H (without offset)
27C128
0000H (without offset)
27C256
4000H
27C512
C000H
• Function option ROM (one)
The function option ROM is used to specify function options, such as I/O ports. Create the option ROM from
the function option HEX file (C251XXXF.HEX*) output by the function option generator, and insert it into the
F.HEX socket under the top cover.
This ROM is effective even when the ICE is connected, however, this ROM is disregarded due to the loading of
the data from the ICE.
• Segment option ROM (one)
The segment option ROM is used to specify segment output port. Create the segment ROM from the segment
option HEX file (C251XXXS.HEX*) output by the segment option generator, and insert it into the S.HEX
socket in the top cover.
This ROM is effective even when the ICE is connected, however, this ROM is disregarded due to the loading of
the data from the ICE.
• EPROM specifications
Use EPROMs with the following specifications:
Program ROM:
27C64 to 27C512
(250 ns or less access time)
Function option ROM:
27C64 to 27C512
(250 ns or less access time)
Segment option ROM:
27C64 to 27C512
(250 ns or less access time)
* "C251XXX" is an example when set for the S1C62N51.

5.1 Preparation
This section describes the common preparation work necessary when the S5U1C62N51E1 is used by itself and
when it is connected to the ICE.
Before doing the following, be sure to turn the POWER switch of the S5U1C62N51E1 off.
