1 INTRODUCTION
1INTRODUCTION
1.1S5U1C6S3N2E2 Outline
The S5U1C6S3N2E2 is a development tool
for the S1C6S3N2, S1C62N33 and
S1C60N09.
Most of the same functions that the
S1C6S3N2/62N33/60N09 CPU has can be
implemented by writing an application
program and by creating option data with
the function and segment option generators
into EPROMs, and then installing them in
the S5U1C6S3N2E2. (The model to be
evaluated can be switched using the DIP
switch on the S5U1C6S3N2E2 board.)
In addition, the S5U1C6S3N2E2 can interface with the in-circuit emulator ICE (S5U1C62000H), and so
perform a higher level of debugging. The set-up data for each option can be loaded from a PC.

5OPERATION METHOD OF S5U1C6S3N2E2
5.1Preparation
This section describes the common preparation work necessary when the S5U1C6S3N2E2 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 S5U1C6S3N2E2 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 S5U1C6S3N2E2 to connect the S5U1C6S3N2E2 to the target system.
(For the pin layout of each connector, refer to Section 3.3, "S5U1C6S3N2E2 I/O and LCD Connectors".)
Note: There is some difference in specifications between the S5U1C6S3N2E2 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 S5U1C6S3N2E2.
• Program ROMs (two)
The program ROMs contain the application program machine code. Write the Intel-HEX format files
output by the HEX converter or the cross-assembler into EPROMs to create program ROMs. Since two
HEX files containing the high-order section (-H.HEX) and the low-order section (-L.HEX) of the
machine code are output, two EPROMs are created. Insert them into the socket H.HEX and L.HEX
under the top cover, respectively.
These ROMs are not effective when connecting the
S5U1C6S3N2E2 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 to
be used.
• Function option ROM (one)
The function option ROM is used to specify function options, such as I/O port specifications. Create
the function option ROM from the function option HEX file (-F.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.
Table 5.1.2.1 Offset address
EPROM typeOffset value
27C640000H (no offset)
27C1280000H (no offset)
27C2564000H
27C512C000H
• Segment option ROM (one)
The segment option ROM is used to specify segment options for LCD assignment and SEG terminal
output specifications. Create the segment option ROM from the segment option HEX file (-S.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)

Segment option ROM1S.HEX
6.2Differences from Actual IC
Be aware that the S5U1C6S3N2E2 differs in terms of functionality and characteristics from the actual IC.
If these differences are ignored, there is a possibility that the application will not operate properly on an
actual IC even though it might have performed well on the ICE.
Note: The functions indicated with an "∗" in the following explanation can be used when the
S5U1C6S3N2E2 is set for the S1C6S3N2 or the S1C62N33.
■ Core CPU
The S5U1C6S3N2E2 supports the three models, S1C6S3N2, S1C62N33 and S1C60N09. Since each
model has a different core CPU built-in, there is a difference as shown in the following table.
When developing the software for the S1C62N33,
•
be sure to initialize the D flag by the initial routine in the application program,
•
do not read interrupt factor flags and do not write data to the interrupt mask register in the EI status.

<Protective diode at each port>
The S5U1C6S3N2E2 I/O ports are all connected to V
DD and VSS through a protective diode and the
interface voltage with the target system is fixed at +5 V. Therefore, the ports cannot interface with a
voltage level exceeding V
DD–VSS even when the output specification is set to open-drain output.
<Pull-down resistance>
The K ports of the S5U1C6S3N2E2 have a 1 MΩ pull-down resistor and the P ports have a 200 kΩ
pull-down resistor which are different from those of the actual IC. For the resistor value of the actual
IC, refer to the Technical Manual for each model.
The set-up time when the input port is pulled down to low with the pull-down resistor is different
from the actual IC. For example, when a key matrix circuit is configured with input and output ports,
a delay occurs in the input fall time by the pull-down resistor. Note that the delay time between the
S5U1C6S3N2E2 and the actual IC is not same.
■ LCD
• The S5U1C6S3N2E2 has the VADJ control for adjusting the LCD contrast. In the actual IC, the LCD
drive voltage level is fixed.
• The S5U1C6S3N2E2 can output 1/3-bias waveforms only, and cannot output 1/2-bias waveforms.
• The output drive capability of the SEG and COM terminals is different.
• When a SEG terminal is set to DC output, the output level is not be initialized in the S5U1C6S3N2E2.
However, it is initialized in the S1C6S3N2 and S1C60N09. In the S1C62N33, it is not initialized similar
to the S5U1C6S3N2E2, but the undefined status is different from the S5U1C6S3N2E2.
■ Difference in current consumption
Current consumption in the S5U1C6S3N2E2 greatly differs from that in the actual IC. To evaluate the
approximate current consumption of the actual IC, check the LEDs on the S5U1C6S3N2E2. The
following lists the items that greatly affect the amount of current consumption:
• Those that can be estimated by checking LEDs and monitor pins
a) Run and Halt execution ratio (on the ICE)
b) AMP operation (AMPON)*
c) OSC3 oscillation ON/OFF circuit (OSCC)*
d) SVD circuit ON/OFF circuit (SVDON or BLS)*
e) Heavy load protection mode (HVLD or HLMOD)
• Those that require attention during system and software design
f) Currents consumed by the internal pull-down resistors
g) Input ports in a floating state
■ Functional difference
<SVD (BLD) circuit>*
• The SVD (BLD) function is implemented by varying the apparent power supply voltage with the
VSVD volume on the S5U1C6S3N2E2 board.
• There is a delay between the time change the power supply voltage and the SVD (BLD) data is
detected. For the S5U1C6S3N2E2, it is shorter than the actual IC. For the actual IC, refer to the Technical Manual of each model and detect the voltage after the sufficient time interval.
<AMP circuit>*
There is a delay between the time change the voltage of the AMP pins and the AMP data is detected.
For the S5U1C6S3N2E2, it is shorter than the actual IC. For the actual IC, refer to the Technical Manual
of each model and choose the sufficient time interval.

<Oscillation circuit>
• The oscillation circuits in the S5U1C6S3N2E2 and the oscillation frequencies are configured according
to the selected model as follows:
When the S5U1C6S3N2E2 is set for the S1C6S3N2:
The OSC1 oscillation frequency is fixed at 32.768 kHz with a crystal oscillator.
The OSC3 oscillation frequency is fixed at 1 MHz when ceramic oscillation is selected. When CR
oscillation is selected, the frequency can be adjusted approximately from 700 kHz to 1.3 MHz.
When the S5U1C6S3N2E2 is set for the S1C62N33:
The OSC1 oscillation frequency is fixed at 32.768 kHz with a crystal oscillator.
The OSC3 oscillation frequency is fixed at 455 kHz when ceramic oscillation is selected. When CR
oscillation is selected, the frequency can be adjusted approximately from 300 kHz to 560 kHz.
When the S5U1C6S3N2E2 is set for the S1C60N09:
The OSC1 oscillation frequency is fixed at 32.768 kHz when crystal oscillation is selected. When CR
oscillation is selected, the frequency can be adjusted approximately from 44 kHz to 85 kHz.
Refer to the Technical Manual of each model for the operating frequency range of the actual IC.
• 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 S5U1C6S3N2E2 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 S5U1C6S3N2E2 is higher than that of the actual IC.
<Waiting time>
The actual IC requires an appropriate waiting time for the operation of the following functions, but
the S5U1C6S3N2E2 may operate properly without the waiting time. Therefore, it may cause a malfunction in the actual IC even though the program operates properly in the S5U1C6S3N2E2. Be sure to
follow the notes described in the Technical Manual of each model.
SVD function(SVDON or BLS)*
AMP function(AMPON)*
<Undefined data memory area>
In the S5U1C6S3N2E2, values that are read from unmapped memory areas will be undefined. However, the undefined status differs from the actual IC, therefore pay attention to the memory area when
creating programs. Refer to the Technical Manual of each model for the memory map.
<Reset circuit>
• The S5U1C6S3N2E2 does not contain an oscillation stop detection circuit (to generate a system reset
signal when the oscillation has stopped). Note that the oscillation stop detection circuit can not
guarantee operation with 100% accuracy.
• The sequence of operations from when the S5U1C6S3N2E2 is turned on until the program starts
operating is different from the actual IC. The S5U1C6S3N2E2 can start executing the program after the
user program and option data are loaded on the S5U1C6S3N2E2.
