1.1 S5U1C60N15E Outline
The S5U1C60N15E is a development tool for the
S1C60N15.
Almost the same functions that the S1C60N15
CPU has can be implemented by writing
application program and option data created by
the option generator into EPROM, and installing
it in the S5U1C60N15E.
In addition, the S5U1C60N15E can interface
with the in-circuit emulator ICE (S5U1C62000H),
and so perform a higher level of debugging.

4.2 Power Cable Connection
When using the S5U1C60N15E on its own, it must be supplied with power (5 V DC, 3 A or more) from an
external source through the power cable.
When the S5U1C60N15E is connected to the ICE, power is supplied by the ICE; therefore, the power cable
is not necessary. Disconnect the power cable if it is already connected.
Figure 4.2.1 shows the connection of the power cable pins.

5.1 Preparation
This section describes the common preparation work necessary when the S5U1C60N15E 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 S5U1C60N15E off.
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 S5U1C60N15E to connect the S5U1C60N15E to the target system.
(For the pin layout of each connector, refer to Section 3.3, "S5U1C60N15E I/O, LCD and Sub-board
Connectors".)
Note: There is some difference in specifications between the S5U1C60N15E 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 S5U1C60N15E.
•Program ROMs (two)
The program ROMs contain the application program machine code. Write the HEX files, that are
converted into the Intel-HEX format by the HEX converter (hx62) from the object files generated by
the linker (lk62), into EPROMs to create program ROMs. Refer to the "S5U1C62000A Manual" for lk62
and hx62. Since two HEX files containing the high-order section (zzzzzzzH.HEX) and the low-order
section (zzzzzzzL.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

5 OPERATION METHOD OF S5U1C60N15E
5.2 Independent Use of S5U1C60N15E
This section describes operation when using the S5U1C60N15E by itself.
The S5U1C60N15E may be used independently by connecting a power supply to it. Use a 5 V DC regula-
tor (more than 3 A) as an external power supply. Connect it with the correct polarity (+ and -).
(Refer to Section 4.2, "Power Cable Connection".)
5.2.1 Power on/off
Before turning the POWER switch of the S5U1C60N15E on, confirm the following:
(1) The power cable is connected correctly.
(2) The target system is connected correctly.
(3) The ROMs have been installed correctly.
After confirming the above items, turn the POWER switch of the S5U1C60N15E on using the following
procedure:
(1) Turn the regulator on. If the regulator is a variable-voltage type, set the output voltage to 5 V ±10%.
(2) Turn the POWER switch of the S5U1C60N15E on.
5.2.2 Debugging
When the S5U1C60N15E is used alone, it provides the following debugging function. The method of
operation is given below.
• Program free run
When the RESET switch (under the top cover) is pressed, the S5U1C60N15E enters the program run
state, and executes the application program from page 1, step 0.
5.3 OperationWhen ICE is Connected
This section explains the operation and use of the S5U1C60N15E when it is connected to the ICE.
Set up the S5U1C60N15E as follows when it is connected to the ICE:
(1) Do not connect the power supply.
(2) Keep on turning the POWER switch off.
5.3.1 Power on/off
Power to the S5U1C60N15E is supplied by the ICE, and the power is switched on and off by pressing the
POWER switch of the ICE. Keep the POWER switch of the S5U1C60N15E off.
5.3.2 Debugging
Debugging is done with the host computer, and the S5U1C60N15E is controlled by the ICE. For the
method of operation, refer to the "S5U1C62000A Manual". The S5U1C60N15E can control the following
four functions:
(1) RESET input
(2) OSC3 CR oscillation frequency adjustment with the OSC3CR control
(3) Pseudo power supply voltage change with the SVDT control
(4) LCD contrast adjustment with the VADJ control

6PRECAUTIONS
Take the following precautions when using the S5U1C60N15E:
6.1 Precautions for Operation
•Turn the power of all equipment off before connecting or disconnecting cables.
•To turn the POWER switch of the S5U1C60N15E off, then on again, wait for at least 10 seconds after
turning off before turning on.
•When ROMs are inserted into the ROM sockets, lock the lever securely by positioning it horizontally.
After the ROMs have been removed from the sockets, lock the lever at the same position above. If the
lever is left upright, poor contact may result.
• Confirm that the following ROMs have been installed correctly, then operate the S5U1C60N15E.
(Top panel) Program ROM 2 L.HEX, H.HEX
(Under top cover) Function option ROM 1 F.HEX
(Under top cover) Segment option ROM 1 S.HEX
6.2 Differences from Actual IC
There are some differences in functions between the S5U1C60N15E and the actual IC.
■I/O
• The response time has been changed by the differences in logic level, output drive capability, and
pull-down resistance. The minimum operating voltage is also different from the actual IC.
• The K ports and the P ports of the S5U1C60N15E have a 100 kΩpull-down resistor which are different
from those of the actual IC.
•When the segment terminals are set to DC output, the output signals are delivered with 0 V and +5 V.
■LCD
• The LCD contrast is adjusted by the VADJ control. However, the contrast level of each actual IC is
fixed, so it cannot be adjusted.
• The output drive capability is different.
• If the internal voltage regulator is disabled by mask option, short-circuit the LCD power supply
terminals and supply external voltage as shown in Table 6.2.1.

■Power-on sequence differences
The S5U1C60N15E performs configuration and determines the internal state when the power is
turned on. Then, it works as the actual IC does. Therefore, the I/O state of the S5U1C60N15E is
unstable until configuration is completed. This affects the power-on reset time.
■Difference in current consumption
It is impossible to evaluate current consumption using the S5U1C60N15E.

(EVALUATION BOARD FOR S1C60N15)
6 PRECAUTIONS
■Function differences
<SVD circuit>
• The SVD function is implemented by varying the apparent power supply voltage with the SVDT
control.
• The SVD response time is different from the actual IC. It is necessary to take an appropriate waiting
time for getting the SVD result.
<Oscillation circuit>
• For OSC1, 32.768 kHz or 38.4 kHz crystal oscillation can be selected.
The OSC3 oscillation frequency is fixed at 1 MHz when ceramic oscillation is used. When CR oscilla-
tion is used, the frequency can be adjusted approximately from 50 kHz to 1400 kHz using the OSC3CR
control mounted on the board.
Either OSC1 or OSC3 can be selected as the system clock.
• The oscillation stabilization time for OSC3 and OSC1 is shorter than the actual IC. The time from
turning the OSC3 oscillation on to switching the system clock to OSC3 should be secured according to
the time of the actual IC.
• Use separate instructions for turning the OSC3 oscillation on and for switching the clock from OSC1
to OSC3. The same applies when turning the OSC1 oscillation off after switching the clock from OSC3
to OSC1. The S5U1C60N15E may operate if this processing is performed at the same time. Be sure to
use separate instructions according to the actual IC when creating the program.
• The oscillation start and stop times are different from those of the actual IC, because the logic level of
the S5U1C60N15E is higher than that of the actual IC.
<Undefined data memory area>
In the S5U1C60N15E, values that are read from unmapped memory areas will be undefined. How-
ever, the undefined status differs from the actual IC, therefore pay attention to the memory area when
creating programs. Refer to the "S1C60N15 Technical Manual" for the memory map.
